ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we filed with the SEC utilizing a “shelf” registration process. Under this shelf registration process, we may, from time to time, sell the debt securities described in this prospectus in one or more offerings.

This prospectus provides you with a general description of the debt securities that we may offer. Each time we sell debt securities, we will provide a prospectus supplement that will contain specific information about the terms of the debt securities and the offering. The prospectus supplement may also add, update or change information contained in this prospectus. The prospectus supplement will supersede this prospectus to the extent it contains information that is different from, or conflicts with, the information contained in this prospectus. You should read this prospectus, any applicable prospectus supplement and any related free writing prospectus that we authorize to be delivered to you together with additional information described under the heading “Where You Can Find More Information” in this prospectus before purchasing any of our debt securities.

We have not authorized any other person to provide you with any information other than that contained or incorporated by reference in this prospectus or in any applicable prospectus supplement or free writing prospectus prepared by or on behalf of us or to which we have referred you. “Incorporated by reference” means that we can disclose important information to you by referring you to another document filed separately with the SEC. We are not responsible for, and can provide no assurance as to the accuracy of, any other information that any other person may give you. We are not making, nor will we make, an offer to sell securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information appearing in this prospectus or in any applicable prospectus supplement or free writing prospectus prepared by or on behalf of us or to which we have referred you, including any information incorporated by reference herein or therein, is accurate as of any date other than their respective dates. Our business, financial condition, results of operations and prospects may have changed since those respective dates.

In this prospectus and any prospectus supplement, “MHFG,” “we,” “us,” and “our” refer to Mizuho Financial Group, Inc. and, unless the context indicates otherwise, its consolidated subsidiaries. “Mizuho Financial Group” refers to Mizuho Financial Group, Inc. Furthermore, unless the context indicates otherwise, these references are intended to refer to us as if we had been in existence in our current form for all periods referred to herein.

Our primary financial statements for SEC reporting purposes are prepared on an annual and semi-annual basis in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), while our financial statements for reporting in our jurisdiction of incorporation and Japanese bank regulatory purposes are prepared in accordance with accounting principles generally accepted in Japan (“Japanese GAAP”). Unless otherwise specified, for purposes of this prospectus, we have presented our financial information in accordance with U.S. GAAP. Unless otherwise stated or otherwise required by the context, all amounts in our financial statements are expressed in yen.

There are certain differences between U.S. GAAP and Japanese GAAP. For a description of certain differences between U.S. GAAP and Japanese GAAP, see “Item 5. Operating and Financial Review and Prospects—Reconciliation with Japanese GAAP” in our most recent annual report on Form 20-F filed with the SEC. You should consult your own professional advisers for a more complete understanding of the differences between U.S. GAAP, Japanese GAAP and the generally accepted accounting principles of other countries and how those differences might affect the financial information contained or incorporated by reference in this prospectus or the accompanying prospectus.

This prospectus or any prospectus supplement or the documents incorporated by reference herein or therein may contain a translation of certain Japanese yen amounts into U.S. dollars for your convenience. However, these translations should not be construed as representations that such yen amounts have been, could have been or could be converted into dollars at the relevant rate or at all.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the financial statements and other documents incorporated by reference in this prospectus contain in a number of places forward-looking statements regarding the intent, belief, current expectations and targets of our management with respect to our financial condition and future results of operations. These statements constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”). In many cases, but not all, we use such words as “aim,” “anticipate,” “believe,” “endeavor,” “estimate,” “expect,” “intend,” “may,” “plan,” “probability,” “project,” “risk,” “seek,” “should,” “strive,” “target” and similar expressions in relation to us or our management to identify forward-looking statements. You can also identify forward-looking statements by discussions of strategy, plans or intentions. These statements reflect our current views with respect to future events and are subject to risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, our actual results may vary materially from those we currently anticipate.

Our actual results or performance could differ materially from those expressed in, or implied by, any forward-looking statements relating to those matters. Accordingly, no assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do so, what impact they will have on our results of operations, cash flows or financial condition. Except as required by law, we are under no obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward-looking statement, whether written or oral, that may be made from time to time, whether as a result of new information, future events or otherwise.

DESCRIPTION OF THE DEBT SECURITIES

The following is a summary of certain general terms and provisions of the senior and subordinated debt securities (collectively, the “debt securities”) that we may offer under this prospectus. The specific terms and provisions of a particular series of debt securities to be offered, and the extent, if any, to which the general terms and provisions summarized below apply to such securities, will be described in an applicable prospectus supplement or free writing prospectus that we authorize to be delivered in connection with such offering. If there is any inconsistency between the general terms and provisions presented here and those in the applicable prospectus supplement or free writing prospectus, those in the applicable prospectus supplement or free writing prospectus will apply.

Because this section is a summary, it does not describe every aspect of the debt securities. It is qualified in its entirety by the provisions of the senior and subordinated indentures (as described below) and the senior and subordinated debt securities, forms of which will be filed as exhibits to a current report on Form 6-K in connection with an offering of the relevant series of debt securities. You should refer to those documents for additional information.

General

We may issue senior debt securities from time to time, in one or more series under a senior indenture between us and The Bank of New York Mellon, which we refer to as the senior trustee, dated as of September 13, 2016, as amended or supplemented from time to time. We may issue subordinated debt securities from time to time, in one or more series under a subordinated indenture between us and The Bank of New York Mellon, which we refer to as the subordinated trustee, dated as of September 13, 2021, as amended or supplemented from time to time, or, if applicable, under a new subordinated indenture to be entered into between us and the subordinated trustee. Subordinated debt securities may be issued with or without a fixed maturity date. The senior indenture and the subordinated indenture are sometimes referred to in this prospectus collectively as the “indentures” and each, individually, as an “indenture,” and the senior trustee and the subordinated trustee are sometimes referred to in this prospectus as the “trustee.” The terms “senior indenture,” “subordinated indenture” and “indenture” as used herein may, depending on the context, refer to such indenture, as amended or supplemented.

The indentures provide or, if applicable, will provide that we may issue debt securities up to an aggregate principal amount as we may authorize from time to time. Neither of the indentures limits or, if applicable, will limit the amount of debt securities that we may issue thereunder, nor contains or, if applicable, will contain any limitations on the amount of other indebtedness or other liabilities that we or any of our subsidiaries may incur.

The senior debt securities of each series will constitute direct, unconditional, unsubordinated and unsecured obligations of Mizuho Financial Group and rank pari passu and without preference among themselves and with all other unsecured obligations, other than subordinated obligations, of Mizuho Financial Group (except for statutorily preferred exceptions) from time to time outstanding.

The subordinated debt securities of each series will constitute direct, subordinated and unsecured obligations of Mizuho Financial Group and rank pari passu and without preference among themselves.

Further Issuances

Mizuho Financial Group reserves the right, from time to time, without the consent of the holders of the debt securities of a particular series, to issue additional debt securities on terms and conditions identical to those of a series offered by this prospectus and the applicable prospectus supplement, which additional debt securities shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the debt securities of such series; provided however that Mizuho Financial Group shall not issue any further debt securities with the same CUSIP, ISIN or other identifying number as that series of debt securities unless such further debt securities will be treated as fungible with that series of debt securities for U.S. federal income tax purposes. Mizuho Financial Group may also, without the consent of the holders of the outstanding debt securities, issue other debt securities under the indentures as part of a separate series that have different terms from the debt securities offered hereby.

Payment of Additional Amounts

All payments of principal and interest in respect of the debt securities by Mizuho Financial Group shall be made without withholding or deduction for, or on account of, any present or future taxes, duties, assessments, levies or governmental charges of whatever nature imposed or levied by or on behalf of Japan, or any political subdivision of, or any authority in, or of, Japan having power to tax (“Japanese taxes”), unless such withholding or deduction is required by law. In that event, Mizuho Financial Group shall pay to the holder of each debt security such additional amounts (all such amounts being referred to herein as “additional amounts”) as may be necessary so that the net amounts received by it after such withholding or deduction shall equal the respective amounts which would have been receivable in respect of such debt security in the absence of such withholding or deduction.

However, no such additional amounts shall be payable in relation to any such withholding or deduction in respect of any payment on a debt security:

(i) to or on behalf of a holder or beneficial owner of a debt security who is an individual non-resident of Japan or a non-Japanese corporation and is liable for such Japanese taxes in respect of such debt security by reason of its (a) having some connection with Japan other than the mere holding of such

10

debt security, or (b) being a person having a special relationship with Mizuho Financial Group (a “specially-related person of Mizuho Financial Group”) as described in Article 6, Paragraph 4 of the Special Taxation Measures Act of Japan (Act No. 26 of 1957, as amended; the “Special Taxation Measures Act”);

(ii) to or on behalf of a holder or beneficial owner of a debt security (a) who would be exempt from any such withholding or deduction but who fails to comply with any applicable requirement to provide certification, information, documents or other evidence concerning its nationality, residence, identity or connection with Japan, including any requirement to provide interest recipient information (as defined below) or to submit a written application for tax exemption (as defined below) to Mizuho Financial Group or a paying agent, as appropriate, or (b) whose interest recipient information is not duly communicated through the participant (as defined below) and the relevant international clearing organization to a paying agent;

(iii) to or on behalf of a holder or beneficial owner of a debt security who is for Japanese tax purposes treated as an individual resident of Japan or a Japanese corporation (except for (A) a designated financial institution (as defined below) who complies with the requirement to provide interest recipient information or to submit a written application for tax exemption and (B) an individual resident of Japan or a Japanese corporation who duly notifies (directly or through the participant or otherwise) a paying agent of its status as not being subject to Japanese taxes to be withheld or deducted by Mizuho Financial Group, by reason of such individual resident of Japan or Japanese corporation receiving interest on the relevant debt security through a payment handling agent in Japan appointed by it);

(iv) to or on behalf of a holder or beneficial owner of a debt security who presents a debt security for payment (where presentation is required) more than 30 days after the relevant date (as defined below), except to the extent that such holder or beneficial owner of a debt security would have been entitled to such additional amounts on presenting the same on any date during such 30-day period;

(v) to or on behalf of a holder who is a fiduciary or partnership or is not the sole beneficial owner of the payment of the principal of, or any interest on, any debt security, and Japanese law requires the payment to be included for tax purposes in the income of a beneficiary or settlor with respect to such fiduciary or a member of such partnership or a beneficial owner, in each case, who would not have been entitled to such additional amounts had it been the holder of such debt security; or

(vi) in any case that is a combination of any of (i) through (v) above.

Where a debt security is held through a participant of a clearing organization or a financial intermediary (each, a “participant”), in order to receive payments free of withholding or deduction by Mizuho Financial Group for, or on account of, Japanese taxes, if the relevant beneficial owner of a debt security is (i) an individual non-resident of Japan or a non-Japanese corporation that in either case is not a specially-related person of Mizuho Financial Group or (ii) a Japanese financial institution (a “designated financial institution”) falling under certain categories prescribed by Article 6, Paragraph 11 of the Special Taxation Measures Act and the cabinet order thereunder (together with the ministerial ordinance and other regulations thereunder, the “Act”), all in accordance with the Act, such beneficial owner of a debt security must, at the time of entrusting a participant with the custody of the relevant debt security, provide certain information prescribed by the Act to enable the participant to establish that such beneficial owner of a debt security is exempted from the requirement for Japanese taxes to be withheld or deducted (the “interest recipient information”) and advise the participant if such beneficial owner of a debt security ceases to be so exempted, including the case where the relevant beneficial owner of the debt security who is an individual non-resident of Japan or a non-Japanese corporation becomes a specially-related person of Mizuho Financial Group.

Where a debt security is not held by a participant, in order to receive payments free of withholding or deduction by Mizuho Financial Group for, or on account of, Japanese taxes, if the relevant beneficial owner of a debt security is (i) an individual non-resident of Japan or a non-Japanese corporation that in either case is not a

11

specially-related person of Mizuho Financial Group or (ii) a designated financial institution, all in accordance with the Act, such beneficial owner of a debt security must, prior to each date on which it receives interest, submit to Mizuho Financial Group or a paying agent, as appropriate, a written application for tax exemption (hikazei tekiyo shinkokusho) (a “written application for tax exemption”) in the form obtainable from Mizuho Financial Group or any paying agent, as appropriate, stating, among other things, the name and address (and, if applicable, the Japanese individual or corporation ID number) of such beneficial owner of a debt security, the title of the debt securities, the relevant interest payment date, the amount of interest payable and the fact that such beneficial owner of a debt security is qualified to submit the written application for tax exemption, together with documentary evidence regarding its identity and residence.

As used in this section, the “relevant date” means the date on which any payment in respect of a debt security first becomes due, except that, if the full amount of the moneys payable has not been duly received by the paying agent on or prior to such due date, it means the date on which, the full amount of such moneys having been so received, notice to that effect is duly given to the holders in accordance with the indenture.

The obligation to pay additional amounts shall not apply to (i) any estate, inheritance, gift, sales, excise, transfer, personal property or any similar tax, assessment or other governmental charge or (ii) any tax, assessment or other governmental charge that is payable otherwise than by deduction or withholding from payments of principal or interest on the debt securities; provided that, except as otherwise set forth in the debt securities and the indenture, Mizuho Financial Group shall pay all stamp and other duties, if any, which may be imposed by Japan, the United States or any respective political subdivision or any taxing authority thereof or therein, with respect to the indenture or as a consequence of the issuance of the debt securities.

In addition, no additional amounts will be payable for or on account of any deduction or withholding imposed pursuant to Sections 1471-1474 of the U.S. Internal Revenue Code, the U.S. Treasury regulations thereunder and any other official guidance thereunder (“FATCA”), any intergovernmental agreement entered into with respect to FATCA, or any law, regulation or other official guidance enacted in any jurisdiction implementing, or relating to, FATCA, similar legislation under the laws of any other jurisdiction, or any such intergovernmental agreement.

References to principal or interest in respect of the debt securities shall be deemed to include any additional amounts due in respect of Japanese taxes which may be payable as set forth in the debt securities and the indenture.

Events of Default and Events of Acceleration

Senior Debt Securities

An event of default with respect to any series of senior debt securities is defined under the senior indenture as any one or more of the following events, subject to modification in a supplemental indenture, each of which we refer to in this prospectus and the applicable prospectus supplement or free writing prospectus as an event of default, having occurred and be continuing:

(i) default by Mizuho Financial Group in the payment when due of the interest or principal in respect of any of the senior debt securities of such series and the continuance of any such default for a period of 30 days after the date when due, unless Mizuho Financial Group shall have cured such default by payment within such period;

(ii) Mizuho Financial Group shall fail duly to perform or observe any other term, covenant or agreement contained in any of the senior debt securities of such series or in the senior indenture in respect of the senior debt securities of such series for a period of 90 days after the date on which written notice of such failure, requiring Mizuho Financial Group to remedy the same, shall have been given first to Mizuho Financial Group (and to the trustee in the case of notice by holders referred to in “—Acceleration Upon an Event of Default” below) by the senior trustee or holders of at least 25% in

Provision and Withholding of Notice of Default. Pursuant to the senior indenture, the senior trustee shall give notice to the holders of the relevant series of senior debt securities of all defaults known to the senior trustee which have occurred. The senior trustee shall transmit the notice within 90 days after the occurrence of an event of default, unless the defaults have been cured before the transmission of such notice. However, except in the case of default in the payment of principal of or interest on the senior debt securities, the senior trustee may withhold notice of default if and so long as responsible officers of the trustee determine in good faith that the withholding of the notice is in the interests of the holders of the relevant series of senior debt securities.

Acceleration Upon an Event of Default. The senior indenture provides that, unless otherwise set forth in a supplemental indenture, if any event of default occurs and is continuing with respect to a series of senior debt securities, either the senior trustee or the holders of not less than 25% in aggregate principal amount of the outstanding senior debt securities of such series, by notice in writing to Mizuho Financial Group (and to the trustee if given by the holders), may declare the principal of and accrued interest on the senior debt securities of such series to be due and payable immediately.

Subordinated Debt Securities

Events of acceleration applicable to a series of subordinated debt securities will be described in an applicable prospectus supplement or free writing prospectus and set forth in the subordinated indenture relating to such series of subordinated debt securities.

Annulment of Acceleration and Waiver of Defaults

In the case of senior debt securities, in some circumstances, if any or all of the events leading to acceleration under the senior indenture, other than the non-payment of the principal of the senior debt securities that has become due as a result of an acceleration, have been cured, waived or otherwise remedied, then the holders of a majority in aggregate principal amount of a series of senior debt securities may (if certain conditions are satisfied) annul past declarations of acceleration or waive past defaults of such series of senior debt securities.

13

Application of Proceeds

Any money collected from Mizuho Financial Group by a trustee under the relevant indenture upon an event of default (in the case of senior debt securities) or any wind-up, bankruptcy or similar proceeding, subject to subordination provisions and write-down provisions that will be described in an applicable prospectus supplement or free writing prospectus and set forth in the subordinated indenture (in the case of subordinated debt securities) shall be applied in the order described below:

(i) first, to the payment of costs, fees and expenses to the applicable trustee and any paying agent for the series of debt securities for which money was collected, including reasonable compensation;

(ii) second, if payment is not due on the principal of the series of debt securities for which money was collected, to the payment of interest on such series of debt securities;

(iii) third, if payment in accordance with the relevant indenture is due on the principal of the series of debt securities for which money was collected, to the payment of the whole amount then owing and unpaid upon all of the debt securities of such series for principal and interest, with interest on the overdue principal; and in case the money collected shall be insufficient to pay in full the whole amount so due and unpaid upon the debt securities of such series, then to the payment of principal and interest without preference or priority of principal over interest, ratably to the aggregate of such principal and accrued and unpaid interest; and

(iv) finally, to the payment of the remainder, if any, to Mizuho Financial Group or any other person lawfully entitled thereto.

Indemnification of Trustee for Actions Taken on Behalf of Securityholders

The indentures provide or, if applicable, will provide that the trustee with respect to the relevant debt securities shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the holders of such debt securities relating to the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred upon the trustee. In addition, the indentures contain or, if applicable, will contain a provision entitling the relevant trustee, subject to the duty of the trustee to act with the required standard of care during a default, to be indemnified to its satisfaction by the holders of relevant debt securities under the relevant indenture before proceeding to exercise any right or power at the request of such holders. Subject to these provisions and specified other limitations, the holders of a majority in aggregate principal amount of a series of debt securities outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the relevant trustee, or exercising any trust or power conferred on the relevant trustee.

Limitation on Suits by Individual Securityholders

The indentures provide that no individual holder of debt securities may institute any action against Mizuho Financial Group under the relevant indenture, except actions for payment of overdue principal and interest, unless the following actions have occurred:

(i) (in the case of senior debt securities) a holder must have previously given written notice to the trustee of the continuing default;

(ii) the holders of not less than 25% in aggregate principal amount of the debt securities of the affected series, with each such series treated as a single class, must have:

(a) made written request to the trustee to institute that action; and

(b) offered the trustee reasonable indemnity;

(iii) the trustee must have failed to institute that action within 60 days after receipt of the request referred to above; and

14

(iv) the holders of a majority in principal amount of the debt securities of the affected series, voting as one class, must not have given directions to the trustee inconsistent with those of the holders referred to above.

However, the right of any holder of debt securities to institute suit for the enforcement of any such payment of overdue principal and interest on or after the respective due dates shall not be affected or impaired; provided that, in the case of subordinated debt securities, notwithstanding the foregoing, the rights of holders of subordinated debt securities specified above are subject to the limitations and suspension of rights triggered by an event triggering any write-down. For the avoidance of doubt, nothing shall be construed to impair the effectiveness of the provisions of subordination and write-down set forth in the subordinated indenture or related provisions of the subordinated debt securities.

Covenants

Consolidation, Merger, Sale or Conveyance. The indentures contain or, if applicable, will contain provisions permitting Mizuho Financial Group, without the consent of the holders of the debt securities, to merge or consolidate with or merge into, or sell, assign, transfer, lease or convey all or substantially all of its properties or assets to any person or persons, provided that (i) Mizuho Financial Group is the surviving party of the consolidation or merger or sale, assignment, transfer, lease or conveyance, or (ii) the successor person or persons that is formed by such consolidation, into which Mizuho Financial Group is merged, or that acquires such properties or assets by the sale, assignment, transfer, lease or conveyance is a joint stock company (kabushiki kaisha) organized under the laws of Japan and assumes Mizuho Financial Group’s obligations on the debt securities and under the indenture and on all series of securities issued thereunder and certain other conditions are met, including that, immediately after giving effect to such transaction, no event of default, in the case of the senior debt securities, and no event of acceleration, in the case of the subordinated debt securities, has occurred and is continuing.

Before the consummation of the proposed consolidation, merger, sale, assignment, transfer, lease or conveyance, Mizuho Financial Group shall deliver an officer’s certificate, and an opinion of counsel, to the effect that the conditions set forth above and in the indenture have been met. The trustee shall be entitled to rely conclusively and without liability upon such officer’s certificate and opinion of counsel.

Evidence of Mizuho Financial Group’s Compliance. There are or, if applicable, will be provisions in the indentures requiring Mizuho Financial Group to furnish to the trustee each year a brief certificate from its principal executive, financial or accounting officer as to his or her knowledge of Mizuho Financial Group’s compliance with all conditions and covenants under the indenture.

Limitation on Actions for Attachment

Each holder of the senior debt securities and the senior trustee acknowledge, accept, consent and agree, for a period of 30 days from and including the date upon which the Prime Minister of Japan confirms that specified item 2 measures (tokutei dai nigo sochi), which are the measures set forth in Article 126-2, Paragraph 1, Item 2 of the Deposit Insurance Act of Japan (Act No. 34 of 1971, as amended) (the “Deposit Insurance Act”) (or any successor provision thereto), need to be applied to Mizuho Financial Group, not to initiate any action to attach any of our assets, the attachment of which has been prohibited by designation of the Prime Minister of Japan pursuant to Article 126-16 of the Deposit Insurance Act (or any successor provision thereto).

Mizuho Financial Group shall, as soon as practicable after the Prime Minister of Japan has confirmed that specified item 2 measures (tokutei dai nigo sochi) need to be applied to Mizuho Financial Group, deliver a written notice of such event to the senior trustee and to the holders of the senior debt securities. Any failure or delay by Mizuho Financial Group to provide such written notice shall not change or delay the effect of the acknowledgement, acceptance, consent and agreement described in the preceding paragraph.

15

Limited Rights to Set Off by Holders

Subject to applicable law, each holder of the senior debt securities, by acceptance of any interest in the senior debt securities, agrees that, if (a) Mizuho Financial Group shall institute proceedings seeking adjudication of bankruptcy or seeking reorganization under the Bankruptcy Act of Japan (act No. 75 0f 2004, as amended), the Civil Rehabilitation Act of Japan (Act No. 225 of 1999, as amended), the Corporate Reorganization Act of Japan (Act No. 154 of 2002, as amended), the Companies Act of Japan (Act No. 86 of 2005, as amended) or any other similar applicable law of Japan, and as long as such proceedings shall have continued, or a decree or order by any court having jurisdiction shall have been issued adjudging Mizuho Financial Group bankrupt or insolvent or approving a petition seeking reorganization under any such laws, and as long as such decree or order shall have continued undischarged or unstayed, or (b) the Prime Minister of Japan confirms that specified item 2 measures (tokutei dai nigo sochi) need to be applied to Mizuho Financial Group, it will not, and waives its right to, exercise, claim or plead any right of set off, compensation or retention in respect of any amount owed to it by Mizuho Financial Group arising under, or in connection with, the senior debt securities or the senior indenture.

Permitted Transfer of Assets or Liabilities

Notwithstanding certain requirements under the senior indenture relating to Mizuho Financial Group’s ability to merge or consolidate with or merge into, or sell, assign, transfer, lease or convey all or substantially all of its properties or assets to any person or persons as described in “—Covenants—Consolidation, Merger, Sale or Conveyance”, each holder of the senior debt securities and the senior trustee acknowledge, accept, consent and agree to any transfer of Mizuho Financial Group’s assets (including shares of subsidiaries of Mizuho Financial Group) or liabilities, or any portions thereof, with permission of a Japanese court in accordance with Article 126-13 of the Deposit Insurance Act (or any successor provision thereto), including any such transfer made pursuant to the authority of the Deposit Insurance Corporation of Japan to represent and manage and dispose of Mizuho Financial Group’s assets under Article 126-5 of the Deposit Insurance Act (or any successor provision thereto), and that any such transfer shall not constitute a sale, assignment, transfer, lease or conveyance of its properties or assets for the purpose of such requirements.

Discharge

Unless otherwise set forth in a supplemental indenture, Mizuho Financial Group may discharge all of its obligations with respect to any or all series of debt securities, other than as to transfers and exchanges, under each indenture after Mizuho Financial Group has, among other things:

(i) paid or caused to be paid the principal of and interest on all of the outstanding debt securities or such series outstanding under the relevant indenture in accordance with their terms;

(ii) delivered to the paying agent or registrar, as applicable, for cancellation all of such outstanding debt securities or such series; or

(iii) in the case of subordinated debt securities, all securities of a series outstanding under the subordinated indenture shall have been cancelled in connection with a write-down pursuant to write-down provisions set forth in the subordinated indenture.

Modification of the Indenture

In the case of subordinated debt securities, no amendment or modification which is prejudicial to any present or future creditor in respect of any senior indebtedness (as such term is defined with respect to the relevant series of subordinated debt securities) shall be made to the subordination provision contained in the relevant subordinated indenture. No such amendment shall in any event be effective against such creditor.

16

Modification without Consent of Holders. Mizuho Financial Group and the trustee may enter into supplemental indentures without the consent of the holders of debt securities issued under each indenture to:

(i) evidence the assumption by a successor corporation of Mizuho Financial Group’s obligations under the indenture;

(ii) add covenants for the protection of the holders of debt securities;

(iii) cure any ambiguity or correct any inconsistency;

(iv) add to, change or eliminate any of the provisions of the indenture (provided that such addition, change or elimination shall not adversely affect the interests of the holders of any outstanding series of debt securities in any material respect);

(v) establish the forms or terms of the debt securities of any series;

(vi) evidence the acceptance of appointment by a successor trustee; or

(vii) in the case of subordinated debt securities, allow for the possibility of repayment of principal and interest that is written down pursuant to any write-down, bail-in or other provisions applicable to a particular series of subordinated debt securities, to the extent that Mizuho Financial Group considers that it has become permissible to do so under relevant laws and regulations applicable at the time of modification.

Modification with Consent of Holders. Mizuho Financial Group and the trustee, with the consent of the holders of not less than a majority in aggregate principal amount of each affected series of outstanding debt securities, may add any provisions to, or change in any manner or eliminate any of the provisions of, the indentures or modify in any manner the rights of the holders of debt securities issued under each indenture; provided, however, that Mizuho Financial Group and the trustee may not make any of the following changes to the terms of the debt securities, without the consent of each holder that would be affected by the change:

(i) extend the final maturity of any debt securities of any series or of any installment of principal of any such debt securities;

(ii) reduce the principal amount;

(iii) reduce the rate or extend the time of payment of interest;

(iv) reduce any amount payable on redemption;

(v) change the currency or other terms in or under which the principal, including any amount of original issue discount, premium, or interest on any debt securities of any series is payable;

(vii) impair the right to receive payment of the principal of and interest on any debt securities on or after the respective due dates expressed in such debt securities;

(viii) impair the right to institute suit for the enforcement of any payment on any debt securities when or after due;

17

Concerning the Trustee

Any trustee appointed pursuant to the indentures will have and will be subject to all of the duties and responsibilities under the relevant indenture and those with respect to an indenture trustee under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The indentures provide or, if applicable, will provide that upon the occurrence of an event of default with respect to a series of senior debt securities (in the case of senior debt securities) or an event of acceleration with respect to a series of subordinated debt securities (in the case of the subordinated debt securities), the trustee with respect to the relevant debt securities will exercise the rights and powers vested in it by the relevant indenture, using the same degree of care and skill as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. In the absence of such event of default or event of acceleration, the trustee need only perform those duties that are specifically set forth in the relevant indenture or are applicable pursuant to the Trust Indenture Act.

Subject to the relevant indenture and the provisions of the Trust Indenture Act, the trustee will be under no obligation to exercise any rights, trusts or powers conferred under the relevant indenture or the debt securities for the benefit of the holders of the debt securities, unless the holders have offered to the trustee indemnity and/or security reasonably satisfactory to the trustee against any loss, cost, liability or expense which might be incurred by it in exercising any such rights, trusts or powers.

The indentures contain or, if applicable, will contain, and the Trust Indenture Act contains, limitations on the rights of the trustee thereunder, should it become a creditor of ours or any of our subsidiaries, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The trustee is permitted to serve as trustee under the senior indenture while also serving as trustee under the subordinated indenture, and to engage in other transactions, provided that if it acquires any conflicting interest (as defined in Section 310(b) of the Trust Indenture Act), it must eliminate such conflict or resign.

The indentures provide or, if applicable, will provide that we will indemnify the trustee and each predecessor trustee for, and to hold it harmless against, any loss, liability or expenses arising out of or in connection with the acceptance or administration of the relevant indenture or the trusts thereunder and the performance of such party’s duties thereunder, including properly incurred costs and expenses of defending itself against or investigating any claim of liability, except to the extent such loss, liability or expense is due to the negligence or bad faith of the trustee or such predecessor trustee.

We and our subsidiaries and affiliates may maintain ordinary banking relationships and custodial facilities with any trustee or its affiliates.

Successor Trustee

The indentures provide or, if applicable, will provide that the trustee with respect to a series of debt securities may resign or be removed by us, effective upon acceptance by a successor trustee of its appointment. The indentures require or, if applicable, will require, and the Trust Indenture Act requires, that any successor trustee shall be a corporation with a combined capital and surplus of not less than $50,000,000 and shall be a corporation organized and doing business under the laws of the United States or any state or territory or of the District of Columbia. No person may accept its appointment as a successor trustee with respect to the debt securities of a series unless at the time of such acceptance such successor trustee is qualified and eligible under the relevant indenture and the applicable provisions of the Trust Indenture Act.

Repayment of Funds

The indentures provide or, if applicable, will provide that all monies paid by Mizuho Financial Group to the trustee or paying agent for a particular series of debt securities for payment of principal or interest on any debt

18

security which remains unclaimed at the end of two years after such payment shall become due and payable will be repaid to Mizuho Financial Group and all liability of the trustee or paying agent with respect thereto will cease, and to the extent permitted by law, the holder of such debt security shall thereafter look only to Mizuho Financial Group for any payment which such holder may be entitled to collect.

New York Law to Govern

The indentures and the debt securities are or, if applicable, will be governed by and construed in accordance with the laws of the State of New York.

Consent to Service of Process and Submission to Jurisdiction

Under the indentures, Mizuho Financial Group irrevocably designates Mizuho Bank, Ltd. as its authorized agent for service of process in any legal action or proceeding arising out of or relating to the indentures or any debt securities brought in any federal or state court in the County of New York, and Mizuho Financial Group irrevocably submits to the jurisdiction of those courts.

Methods of Receiving Payments

The principal of, and interest and additional amounts on, the debt securities represented by the Global Notes (as defined below) will be payable in U.S. dollars, unless the applicable prospectus supplement or free writing prospectus will specify otherwise. Subject to the terms of the relevant indenture, the paying agent will hold all sums received by it for the payment of the principal and interest on the debt securities in trust for the benefit of the holders. Mizuho Financial Group will cause the paying agent to pay such amounts received by it, on the dates payment is to be made, directly to The Depository Trust Company (“DTC”).

Book-Entry; Delivery and Form

DTC

The debt securities will initially be issued to investors only in book-entry form. Each series of debt securities will initially be in the form of one or more fully registered global notes (the “Global Notes”). The Global Notes will be issued and registered in the name of Cede & Co., acting as nominee for DTC, which will act as securities depositary for the debt securities. The Global Notes will initially be deposited with The Bank of New York Mellon, acting as custodian for DTC.

Ownership of beneficial interests in a Global Note will be limited to persons who have accounts with DTC (“participants”), or persons who hold interests through participants (including Euroclear and Clearstream). Ownership of beneficial interests in a Global Note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). Unless and until debt securities in certificated form are issued, the only registered holder will be Cede & Co., as nominee of DTC, or the nominee of a successor depositary.

Investors may hold their interests in a Global Note directly through DTC if they are participants in such system, or indirectly through organizations that are participants in such system, including Euroclear or Clearstream. Euroclear and Clearstream will hold interests in the Global Notes on behalf of their participants through DTC. Beneficial owners will be permitted to exercise their rights only indirectly through DTC, Euroclear, Clearstream and their participants.

DTC advises that it is a limited purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of New York Banking Law, a member of the Federal Reserve System, a

19

“clearing corporation” within the meaning of the New York Uniform Commercial Code and a “Clearing Agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities for its participants and facilitates the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of securities certificates. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly (“indirect participants”).

Euroclear

Euroclear holds securities and book-entry interests in securities for participating organizations and facilitates the clearance and settlement of securities transactions between Euroclear participants, and between Euroclear participants and participants of certain other securities intermediaries through electronic book-entry changes in accounts of such participants or other securities intermediaries. Euroclear provides Euroclear participants, among other things, with safekeeping, administration, clearance and settlement, securities lending and borrowing, and related services. Euroclear participants are investment banks, securities brokers and dealers, banks, central banks, supranationals, custodians, investment managers, corporations, trust companies and certain other organizations. Non-participants in the Euroclear system may hold and transfer book-entry interests in the debt securities through accounts with a participant in the Euroclear system or any other securities intermediary that holds a book-entry interest in the securities through one or more securities intermediaries standing between such other securities intermediary and Euroclear.

Investors electing to acquire, hold or transfer debt securities through an account with Euroclear or some other securities intermediary must follow the settlement procedures of such intermediary with respect to the settlement of secondary market transactions in debt securities. Euroclear will not monitor or enforce any transfer restrictions with respect to the debt securities. Investors that acquire, hold and transfer interests in the debt securities by book-entry through accounts with Euroclear or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such intermediary and each other intermediary, if any, standing between themselves and the individual debt securities.

Euroclear has advised that, under Belgian law, investors that are credited with securities on the records of Euroclear have a co-property right in the fungible pool of interests in securities on deposit with Euroclear in an amount equal to the amount of interests in securities credited to their accounts. In the event of the insolvency of Euroclear, Euroclear participants would have a right under Belgian law to the return of the amount and type of interests in securities credited to their accounts with Euroclear. If Euroclear did not have a sufficient amount of interests in securities on deposit of a particular type to cover the claims of all participants credited with such interests in securities on Euroclear’s records, all participants having an amount of interests in securities of such type credited to their accounts with Euroclear would have the right under Belgian law to the return of their pro rata share of the amount of interests in securities actually on deposit. Under Belgian law, Euroclear is required to pass on the benefits of ownership in any interests in debt securities on deposit with it (such as dividends, voting rights and other entitlements) to any person credited with such interests in securities on its records.

Distributions with respect to the debt securities held beneficially through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the Euroclear terms and conditions.

Clearstream

Clearstream advises that it is incorporated under the laws of Luxembourg and licensed as a bank and professional depositary. Clearstream holds securities for its participating organizations and facilitates the clearance and settlement of securities transactions among its participants through electronic book-entry changes in accounts of

20

its participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to its participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. Clearstream has established an electronic bridge with the Euroclear operator to facilitate the settlement of trades between Clearstream and Euroclear. As a registered bank in Luxembourg, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector. Clearstream customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations. In the United States, Clearstream customers are limited to securities brokers and dealers and banks, and may include the underwriters of an offering of debt securities. Other institutions that maintain a custodial relationship with a Clearstream customer may obtain indirect access to Clearstream. Clearstream is an indirect participant in DTC.

Distributions with respect to debt securities held beneficially through Clearstream will be credited to cash accounts of Clearstream participants in accordance with its rules and procedures.

Other Clearing Systems

We may choose any other clearing system for a particular series of debt securities. The clearance and settlement procedures for the clearing system we choose will be described in the applicable prospectus supplement or free writing prospectus.

Transfers

Purchases of debt securities within the DTC system must be made by or through DTC participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each actual purchaser of debt securities, a beneficial owner of an interest in a Global Note, is in turn to be recorded on the DTC participants’ and indirect participants’ records. Beneficial owners of interests in a Global Note will not receive written confirmation from DTC of their purchases, but they are expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the DTC participants or indirect participants through which they purchased the debt securities. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of DTC participants and indirect participants acting on behalf of beneficial owners of interests in a Global Note. Beneficial owners of interests in a Global Note will not receive debt securities in certificated form representing their ownership interests in the debt securities unless use of the book-entry system for the debt securities is discontinued.

Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds. Transfers between participants in Euroclear and Clearstream will be effected in the ordinary way in accordance with their respective rules and operating procedures.

Subject to compliance with the transfer restrictions applicable to the debt securities, cross-market transfers between persons holding, directly or indirectly through DTC, on the one hand, and directly or indirectly through Euroclear or Clearstream participants, on the other, will be effected in DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the relevant European depositary; however, those cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in that system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the relevant European depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the European depositaries.

Because of time zone differences, credits of securities received in Euroclear or Clearstream as a result of a transaction with a person that does not hold the debt securities through Euroclear or Clearstream will be made

21

during subsequent securities settlement processing and dated the clearing system business day following the DTC settlement date. Those credits or any transactions in those securities settled during that processing will be reported to the relevant Euroclear or Clearstream participants on that business day. Cash received in Euroclear or Clearstream as a result of sales of securities by or through a Euroclear participant or a Clearstream participant to a DTC participant will be received with value on the DTC settlement date, but will be available in the relevant Euroclear or Clearstream cash account only as of the clearing system business day following settlement in DTC.

Limitations on Responsibilities

DTC, Euroclear and Clearstream have no knowledge of the actual beneficial owners of interests in a Global Note. DTC’s records reflect only the identity of the DTC participants to whose accounts those debt securities are credited, which may or may not be the beneficial owners of interests in a Global Note. Similarly, the records of Euroclear and Clearstream reflect only the identity of the Euroclear or Clearstream participants to whose accounts those debt securities are credited, which also may or may not be the beneficial owners of interests in a Global Note. DTC, Euroclear and Clearstream participants and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

DTC’s Procedures for Notices, Voting and Payments

So long as DTC, or its nominee, is the registered owner or holder of a Global Note, DTC or that nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the Global Note for all purposes under the debt securities and the indentures. No beneficial owner of an interest in a Global Note will be able to transfer that interest except in accordance with DTC’s applicable procedures, in addition to those provided for under the indentures.

Mizuho Financial Group expects that DTC will take any action permitted to be taken by a holder of the debt securities, including the presentation of debt securities for exchange, only at the direction of one or more of its participants to whose account DTC’s interests in the Global Notes are credited and only in respect of that portion of the aggregate, principal amount of debt securities as to which that participant or participants has or have given the direction.

Conveyance of notices and other communications by DTC to its participants, by those participants to its indirect participants, and by participants and indirect participants to beneficial owners of interests in a Global Note will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

The paying agent will send or forward any notices in respect of the debt securities held in book-entry form to DTC.

Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the debt securities unless authorized by a participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an omnibus proxy to Mizuho Financial Group as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those participants to whose account the debt securities are credited on the record date.

Payment of principal of and interest on the debt securities held in book-entry form will be made to Cede & Co. or another nominee of DTC by the paying agent in immediately available funds. DTC’s practice is to credit its participants’ accounts on the relevant payment date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payments on such payment date. Payments by DTC’s participants and indirect participants to beneficial owners of interests in a Global Note will be governed by standing instructions and customary practices, and will be the responsibility of those participants and indirect participants and not of DTC or Mizuho Financial Group, subject to any statutory or regulatory requirements that

22

may be in effect from time to time. Payment of principal of and interest on the debt securities or other amounts to DTC is the responsibility of Mizuho Financial Group, disbursement of these payments to participants is the responsibility of DTC, and disbursement of those payments to the beneficial owner of an interest in a Global Note is the responsibility of participants and indirect participants.

Although DTC, Euroclear and Clearstream are expected to follow the foregoing procedures in order to facilitate transfers of interests in a Global Note among participants of DTC, Euroclear and Clearstream, they are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither Mizuho Financial Group nor the trustees, the registrar or the paying agent will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their respective operations.

Exchange of Global Notes for Certificated Debt Securities

If DTC is at any time unwilling or unable to continue as a depositary for the Global Notes and a successor depositary is not appointed within 90 days, or if there shall have occurred and be continuing an event of default with respect to the senior debt securities or an event of acceleration with respect to the subordinated debt securities, Mizuho Financial Group will issue debt securities in certificated form in exchange for the Global Notes. The certificated debt securities delivered in exchange for beneficial interests in any Global Note will be registered in the names requested by or on behalf of DTC (in accordance with its customary procedures). Any such exchange shall be made free of charge to the beneficial owners of the Global Notes, except that a person receiving certificated debt securities must bear the cost of insurance, postage, transportation and other related costs in the event that such person does not take delivery of such certificated debt securities at the offices of the paying agent. The debt securities are not issuable in bearer form. Except in the limited circumstances described above, owners of interests in the Global Notes will not be entitled to receive physical delivery of debt securities in certificated form.

Payment of principal and interest in respect of the certificated debt securities shall be payable at the office of agency of Mizuho Financial Group in the City of New York which shall initially be the corporate trust office of the trustees, at 240 Greenwich Street, New York, New York 10286, U.S.A. or at the office of the paying agent (which shall initially be The Bank of New York Mellon), provided that, at the option of Mizuho Financial Group, payment may be made by wire transfer or by mailing checks for such interest payable to or upon the written order of such holders at their last addresses as they appear on the registry books of Mizuho Financial Group (in the case of registered securities) or at such other addresses as may be specified in the written orders of the holders; and provided further that, payments of any interest on certificated debt securities (other than at maturity) may be made by the paying agent, in the case of a registered holder of at least $10,000,000 principal amount of debt securities, by electronic funds transfer of immediately available funds to a United States dollar account maintained by the payee, provided such registered holder so elects by giving written notice to the paying agent designating such account, no later than 15 days immediately preceding the relevant date for payment (or such other date as the paying agent may accept in its discretion). Unless such designation is revoked, any such designation made by such holder with respect to such debt securities shall remain in effect with respect to any future payments with respect to such debt securities payable to such holder.

If any debt securities are listed on any securities exchange, such debt securities will be subject to any applicable rules of such securities exchange.

Other Procedures

The applicable prospectus supplement for subordinated debt securities may describe procedures for any write-down, write-up, bail-in or other provisions applicable to such subordinated debt securities.

23

Registration, Transfer and Exchange of Debt Securities

The registrar will maintain a register with respect to the debt securities. The name of the registered holder of each debt security will be recorded in the register. Mizuho Financial Group, the trustees, the registrar and the paying agent may treat the person in whose name any debt security is registered as the absolute owner of the debt security for all purposes and none of them shall be affected by any notice to the contrary.

At the option of the holder, subject to the restrictions contained in the debt security and in the indenture, the debt security may be transferred or exchanged for a like aggregate principal amount of debt securities of different authorized denominations, upon surrender for exchange or registration of transfer, at the registrar’s office. Any debt security surrendered for exchange or presented for registration of transfer shall be duly endorsed, or be accompanied by a written instrument of transfer or other documentation in a form identified in the indenture. Debt securities issued upon exchange or transfer shall be registered in the name of the holder requesting the exchange or, as the case may be, the designated transferee or transferees and delivered at the registrar’s office, or mailed, at the request, risk and expense of, and to the address requested by, the designated transferee or transferees. No service charge, other than any cost of delivery not made by regular mail, shall be imposed for any transfer or exchange of debt securities, but Mizuho Financial Group or the registrar may require payment of a sum sufficient to cover any stamp duty, tax or governmental charge or insurance charge that may be imposed in connection with any transfer or exchange of debt securities.

Upon the transfer, exchange or replacement of certificated debt securities bearing the legend, the registrar will deliver only certificated debt securities bearing such legend unless Mizuho Financial Group otherwise consents.

Authenticating Agent

The indentures permit or, if applicable, will permit the trustees to appoint an authenticating agent or agents with respect to the debt securities. Such authenticating agent will be authorized to act on behalf of the trustee to authenticate the debt securities and debt securities authenticated by such authenticating agent will be entitled to the benefits of the indenture and valid and obligatory for all purposes as if authenticated by the trustee. The trustee may change the authenticating agent at any time, as more fully described in the indentures.

PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

General

We may offer the debt securities described in this prospectus in one or more of the following ways from time to time:

• to or through underwriters or dealers;

• by ourselves directly;

• through agents;

• through one or more special purpose entities;

• through an exchange distribution in accordance with the rules of the applicable exchange;

• through a combination of any of these methods of sale.

The prospectus supplement relating to an offering of debt securities will set forth the terms of the offering, including:

• a description of the transaction and the debt securities to be offered;

• the name or names of any underwriters, dealers or agents;

• the purchase price of the debt securities and the proceeds we will receive from the sale;

• any underwriting discounts and commissions or agency fees and other items constituting underwriters’ or agents’ compensation;

• the public offering price;

• any discounts or concessions to be allowed or reallowed or paid to dealers; and

• any securities exchanges on which the debt securities may be listed.

Any public offering prices, discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If underwriters are used in an offering of the debt securities, the debt securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The debt securities may be either offered to the public through underwriting syndicates represented by one or more managing underwriters or by one or more underwriters without a syndicate. Unless otherwise set forth in the

25

prospectus supplement, the underwriters will not be obligated to purchase debt securities that are offered unless specified conditions are satisfied, and, unless otherwise set forth in the prospectus supplement, if the underwriters do purchase any debt securities, they will purchase all securities that are offered.

If Mizuho Securities USA LLC or any other broker-dealer affiliate of ours participates in the distribution of our securities, such offering will be conducted in accordance with the applicable requirements of Rule 5121 of the Financial Industry Regulatory Authority’s rules or any successor provisions.

In connection with underwritten offerings of the debt securities offered by this prospectus and in accordance with applicable law and industry practice, underwriters may over-allot or effect transactions that stabilize, maintain or otherwise affect the market price of the debt securities offered by this prospectus at levels above those that might otherwise prevail in the open market, including by entering stabilizing bids, effecting syndicate covering transactions or imposing penalty bids, each of which is described below.

• A stabilizing bid means the placing of any bid, or the effecting of any purchase, for the purpose of pegging, fixing or maintaining the price of a security.

• A syndicate covering transaction means the placing of any bid on behalf of the underwriting syndicate or the effecting of any purchase to reduce a short position created in connection with the offering.

• A penalty bid means an arrangement that permits the managing underwriter to reclaim a selling concession from a syndicate member in connection with the offering when offered securities originally sold by the syndicate member are purchased in syndicate covering transactions.

These transactions may be effected on an exchange or automated quotation system, if the debt securities are listed on that exchange or admitted for trading on that automated quotation system, or in the over-the-counter market or otherwise. Underwriters are not required to engage in any of these activities or to continue these activities if commenced.

If dealers are utilized in the sale of debt securities offered by this prospectus, we will sell the debt securities to the dealers as principals. The dealers may then resell the debt securities to the public at varying prices to be determined by the dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating to that transaction.

Debt securities may be sold directly by us to one or more institutional purchasers, or through agents designated by us from time to time, at a fixed price or prices, which may be changed, or at varying prices determined at the time of sale. Any agent involved in the offer or sale of the debt securities in respect of which this prospectus is delivered will be named, and any commissions payable by us to the agent will be set forth, in the prospectus supplement relating to that offering. Unless otherwise indicated in the applicable prospectus supplement, any agent will be acting on a best efforts basis for the period of its appointment.

If so indicated in the applicable prospectus supplement, we will authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase offered debt securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. These contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth the commission payable for solicitation of the contracts.

Underwriters, dealers and agents may be entitled, under agreements with us, to indemnification by us relating to material misstatements or omissions. Underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for, us and our subsidiaries or affiliates in the ordinary course of business.

Each series of debt securities offered by this prospectus will be a new issue of securities and will have no established trading market. Any underwriters to whom offered securities are sold for public offering and sale

26

may make a market in the offered debt securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The debt securities offered by this prospectus may or may not be listed on a national securities exchange. No assurance can be given that there will be a market for any debt securities offered by this prospectus.

Market-Making Transactions by Affiliates

Mizuho Securities USA LLC or our other affiliates may use this prospectus and the applicable prospectus supplement in market-making transactions involving the debt securities after the initial sale. These transactions may be executed at negotiated prices that are related to market prices at the time of purchase or sale, or at other prices. These affiliates may act as principal or agent in these transactions. These affiliates are not obligated to make a market in any of the debt securities and may discontinue any market-making activities at any time without notice.

The debt securities to be sold in market-making transactions include debt securities to be issued after the date of this prospectus as well as debt securities issued prior to the date of this prospectus.

Information on the trade and settlement dates, as well as the purchase price, for a market-making transaction will be provided to the purchaser in a separate confirmation of sale. Unless you are informed otherwise in the confirmation of sale, this prospectus is being used in a market-making transaction.

LEGAL MATTERS

The validity of the debt securities with respect to United States federal law and New York State law will be passed upon for us by Simpson Thacher & Bartlett LLP, our United States counsel, and for any underwriters, dealers or agents by Davis Polk & Wardwell LLP, United States counsel for them. Nagashima Ohno & Tsunematsu, our Japanese counsel, will pass upon certain legal matters as to Japanese law for us.

ENFORCEMENT OF CIVIL LIABILITIES

Mizuho Financial Group is a joint stock corporation incorporated with limited liability under the laws of Japan. All of its directors and executive officers are non-residents of the United States. All or a substantial portion of the assets of Mizuho Financial Group and the assets of such non-resident persons are located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon us or those persons or to enforce court judgments predicated upon the civil liability provisions of the U.S. federal or state securities laws against us or those persons in the United States. We have been advised by our Japanese counsel, Nagashima Ohno & Tsunematsu, that there is doubt as to the enforceability in Japan, in

27

original actions or in actions for enforcement of judgments of U.S. courts brought before Japanese courts, of civil liabilities predicated solely upon the U.S. federal or state securities laws.

Our agent for service of process is Mizuho Bank, Ltd.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 8. Indemnification of Officers and Directors.

Article 330 and Article 402, Paragraph 3 of the Companies Act of Japan (the “Companies Act”), make the provisions of Articles 643 through 656 of the Civil Code of Japan (the “Civil Code”) applicable to the relationship between us and our directors and executive officers, respectively. Section 10, Chapter 2, Book III of the Civil Code, which consists of Articles 643 to 656, when so applied to the directors or executive officers, among other things, provides in effect that:

(1) any director or executive officer of a company may demand advance payment of expenses which are considered necessary for the management of the affairs of such company entrusted to him or her;

(2) if a director or an executive officer of a company has defrayed any expenses which are considered necessary for the management of the affairs of such company entrusted to him or her, he or she may demand reimbursement therefor together with interest thereon from the company;

(3) if a director or an executive officer has assumed an obligation necessary for the management of the affairs entrusted to him or her, he or she may require the company to perform it in his or her place or, if it is not due, to furnish adequate security; and

(4) if a director or an executive officer, without any fault on his or her part, sustains damage through the management of the affairs entrusted to him or her, he or she may demand compensation therefor from the company.

Under Article 404, Paragraph 4 of the Companies Act, a company may not refuse a demand referred to in subparagraphs (1) through (3) above from a director who serves as member of any of the nominating committee, the audit committee or the compensation committee unless the company establishes that the relevant expense or obligations was or is not necessary for the performance of the director’s duties. The form of underwriting agreement filed as an exhibit to this registration statement provides for indemnification and contribution by the underwriters with respect to certain liabilities of our directors, officers and other controlling persons.

Our directors and executive officers are, to a limited extent, insured under a directors and officers liability insurance policy.

Under the Companies Act, we may exempt, by a resolution of a general meeting of shareholders, our directors and executive officers from liabilities to us arising in connection with their failure to execute their duties if they execute their duties in good faith and without gross negligence, within the limits stipulated by applicable laws and regulations. Our articles of incorporation, in accordance with the Companies Act, allow us to enter into an agreement with outside directors that limits their liabilities incurred in connection with their service. The limitation of liabilities under such agreement, if the outside director performed his or her duty in good faith and without gross negligence, must be the higher of either (i) a pre-determined amount not less than ¥20 million or (ii) the amount prescribed in laws and regulations. Pursuant to the relevant provisions in our articles of incorporation, we have entered into such agreements with all of our outside directors that are currently in office.

Item 9. Exhibits.

Reference is made to the Exhibit Index included herewith which is incorporated herein by reference.

Item 10. Undertakings.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(a) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, or the Securities Act;

(b) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of a prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(c) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a), (b) and (c) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered in the post-effective amendment, and the offering of those securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) To file a post-effective amendment to the registration statement to include any financial statements required by Item 8A of Form 20-F at the start of any delayed offering or throughout a continuous offering. Financial statements and information otherwise required by Section 10(a)(3) of the Securities Act need not be furnished, provided that the registrant includes in the prospectus, by means of a post-effective amendment, financial statements required pursuant to this paragraph (4) and other information necessary to ensure that all other information in the prospectus is at least as current as the date of those financial statements. Notwithstanding the foregoing, a post-effective amendment need not be filed to include financial statements and information required by Section 10(a)(3) of the Securities Act or Item 8A of Form 20-F if such financial statements and information are contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

(5) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be

II-2

deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(7) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the SEC under section 305(b)(2) of the Trust Indenture Act.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

As Representative(s) of the several Underwriters named in Schedule A hereto

Ladies and Gentlemen:

Subject to the terms and conditions stated herein, Mizuho Financial Group, Inc. (the “Issuer”), a joint stock company incorporated under the laws of Japan, confirms its agreement with the several underwriters named in Schedule A hereto (collectively, the “Underwriters”, which term shall also include any underwriter substituted as hereinafter provided in Section 11 hereof), with respect to the issue and sale by the Issuer and the purchase by the Underwriters, acting severally and not jointly, of the respective amounts set forth in such Schedule A of [insert description of the securities] ([insert name of securities], [and together with the [insert name(s) of securities], / or] the “Notes”). [insert name(s) of Representative(s)] have agreed to act as representatives of the Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Notes.

The Notes will be issued pursuant to [a senior indenture dated September 13, 2016][a subordinated indenture dated September 13, 2021] (the “Indenture”) between the Issuer and The Bank of New York Mellon, as trustee and registrar (the “Trustee”). The Indenture, as used herein, includes any Officer’s Certificates (as defined in the Indenture) establishing the form and terms of the Notes pursuant to Section 2.03 of the Indenture. The Notes will be issued in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (“DTC”), pursuant to a letter agreement, dated before the Closing Time (as defined in Section 2(c) below), between the Issuer and DTC.

The Issuer has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “1933 Act”) an “automatic shelf registration statement”, as defined under Rule 405 under the 1933 Act (“Rule 405”), on Form F-3 (File No. 333-[        ]), including a prospectus, relating to debt securities, including the Notes. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the 1933 Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means any prospectus filed with the Commission pursuant to Rule 424(b) under the 1933 Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the 1933 Act) in connection with confirmation of sales of the Notes. If the Issuer has filed an abbreviated registration statement pursuant to Rule 462(b) under the 1933 Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement.

deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “1934 Act”) that are deemed to be incorporated by reference therein.

(xxxi) Accounting Controls and Disclosure Controls

The Issuer and its consolidated subsidiaries maintain systems of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the 1934 Act) that comply with the requirements of the 1934 Act and have been designed by, or under the supervision of, their respective principal executive and principal financial officers, or persons performing similar functions, to provide reasonable assurances regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. The Issuer and each Principal Subsidiary maintain a system of internal accounting controls sufficient to provide reasonable assurances that (1) transactions are executed in accordance with management’s general or specific authorization; (2) transactions are recorded as necessary to permit the preparation of financial statements in conformity with U.S. GAAP or Japanese GAAP, as the case may be, and to maintain accountability for assets; (3) access to assets is permitted only in accordance with management’s general or specific authorization; (4) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (5) interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus is prepared in accordance with the Commission’s rules and guidelines applicable thereto.

(xxxiii) Statistical and Market-Related Data

SECTION 6. Offers and Resales of the Notes

(a) Offer and Sale Procedures

Each of the Underwriters hereby represents and agrees that it has not used and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the 1933 Act (which term includes use of any written information furnished to the Commission by the Issuer and not incorporated by reference into the Registration Statement and any press release issued by the Issuer) other than (i) a free writing prospectus that, solely as a result of use by such Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433, (ii) any Issuer Free Writing Prospectus listed on Annex A or prepared pursuant to Section 1(a)(iii) or Section 3(d) above (including any electronic road show), or (iii) any free writing prospectus prepared by such Underwriter and approved by the Issuer in advance in writing. Notwithstanding the foregoing, the Underwriters may use the Pricing Term Sheet referred to in Annex B hereto without the consent of the Issuer. Each Underwriter, severally and not jointly, represents, warrants and agrees that it and its Affiliates have not offered, sold or delivered and will not offer, sell or deliver any of the Notes in any jurisdiction outside the United States except under circumstances that will result in compliance with the applicable laws thereof, and that it has taken or will take at its own expense whatever action is required to permit its purchase and resale of the Notes in such jurisdictions.

(b) Specially-Related Persons

The Issuer covenants with each Underwriter that prior to the finalization of the allocation of the Notes to the Subsequent Purchasers, the Issuer will identify and inform the Representatives of all Specially-Related Persons of the Issuer (as defined in Section 6(c) below) from the list compiled by the Underwriters of potential Subsequent Purchasers that may purchase any of the Notes from the Underwriters as part of the distribution of the Notes under this Agreement as soon as reasonably practical after the Issuer has received such list from the Underwriters.

(c) Japanese Selling Restrictions

The Notes have not been and will not be registered under the FIEL and are subject to the Special Taxation Measures Act of Japan (Act No. 26 of 1957, as amended) (the “Special Taxation Measures Act”). Each Underwriter, severally and not jointly, represents and warrants to, and agrees with, the Issuer that (i) it has not, directly or indirectly, offered or sold and will not, directly or indirectly, offer or sell any Notes in Japan or to, or for the benefit of, any resident of Japan (which term as used in this clause (i) means any person resident of Japan, including any corporation or other entity organized under the laws of Japan) or to others for reoffering or resale, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the FIEL and any other applicable laws, regulations and governmental guidelines of Japan; and (ii) it has not, directly or indirectly, offered or sold and will not, as part of its distribution pursuant to this Agreement at any time, directly or indirectly offer or sell any Notes to, or for the benefit of, any person other than a beneficial owner that is (a) for Japanese tax purposes, neither (x) an individual resident of Japan or a Japanese corporation, nor (y) an individual non-resident of Japan or a non-Japanese corporation that in either case is a person having a special relationship with the Issuer as described in Article 6, paragraph (4) of the Special Taxation Measures Act (such person is referred to as a “Specially-Related Person of the Issuer”) or (b) a Japanese financial institution, designated in Article 6, paragraph (11) of the Special Taxation Measures Act. Notwithstanding the restriction set forth in (ii) above, pursuant to the Special Taxation Measures Act, Mizuho Securities USA LLC, a Specially-Related Person of the Issuer and acting in its capacity as an Underwriter, will be permitted to acquire or purchase, as part of the distribution of the Notes, the remainder of the Notes from any of the other Underwriters, where such other Underwriter has failed to

25

sell to subsequent purchasers all of the Notes that it acquired or purchased from the Issuer in its capacity as an Underwriter.

SECTION 7. Indemnification

(a) Indemnification of the Underwriters

The Issuer agrees to indemnify and hold harmless each Underwriter, its Affiliates, Selling Agents, directors and officers and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of or based on any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or any omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of or based on any untrue statement or alleged untrue statement of material fact included in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto) or any omission or alleged omission in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto) of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 7(d) below) any such settlement is effected with the written consent of the indemnifying party; and

(iii) against any and all expense whatsoever, as reasonably incurred (including the fees and disbursements of counsel chosen by the Representatives), in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with any information relating to any Underwriter furnished to the Issuer in writing by such Underwriter through the Representatives expressly for use therein.

(b) Indemnification of the Issuer, its Directors and Officers

Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Issuer, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Issuer within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 7, as incurred, but only with respect to any untrue statement or omission,

26

or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or in any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Time of Sale Information or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with any information relating to any Underwriter furnished to the Issuer in writing by such Underwriter through the Representatives expressly for use therein.

(c) Actions Against Parties; Notification

Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 7(a) above, counsel to the indemnified parties shall be selected by the Representatives, and, in the case of parties indemnified pursuant to Section 7(b) above, counsel to the indemnified parties shall be selected by the Issuer. An indemnifying party may participate at its own expense in the defence of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 or Section 8 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse

If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 8. Contribution

If the indemnification provided for in Section 7 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuer, on the one hand, and the Underwriters, on the other hand, from the offering of the Notes pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred

27

to in clause (i) above but also the relative fault of the Issuer, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Issuer, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Notes pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes pursuant to this Agreement (before deducting expenses) received by the Issuer, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, bear to the aggregate initial offering price of the Notes as set forth in the Prospectus.

The relative fault of the Issuer, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Issuer or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Issuer and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 8 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes purchased and sold by it hereunder exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates, officers, directors and Selling Agents shall have the same rights to contribution as such Underwriter, and each director of the Issuer, each officer of the Issuer who signed the Registration Statement, and each person, if any, who controls the Issuer within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Issuer. The Underwriters respective obligations to contribute pursuant to this Section 8 are several in proportion to the principal amount of Notes set forth opposite their respective names in Schedule A hereto, and not joint.

SECTION 9. Representations, Warranties and Agreements to Survive

All representations, warranties and agreements contained in this Agreement or in certificates of officers or directors of the Issuer or any of its subsidiaries submitted pursuant hereto shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates, or Selling Agents, any person controlling any Underwriter, its officers or directors or any person controlling the Issuer and (ii) delivery of and payment for the Notes.

28

SECTION 10. Termination of Agreement

(a) Termination; General

The Representatives may terminate this Agreement, by notice to the Issuer, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the Time of Sale Information or the Prospectus (exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), any material adverse change, or any development involving a prospective material adverse change, in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Issuer and its subsidiaries (considered as one enterprise), in either case whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in Japan, the United Kingdom, the United States or other international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions or currency exchange rates, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Notes, to enforce contracts for the sale of the Notes or to deliver the Notes, or (iii) if trading in any securities of the Issuer or any of its subsidiaries has been suspended or materially limited on any exchange, or (iv) if trading generally on the Tokyo Stock Exchange, the New York Stock Exchange, NYSE Amex Equities (formerly the American Stock Exchange), the London Stock Exchange, The NASDAQ Stock Market or the SGX-ST has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the FSA, the U.K. Listing Authority, the London Stock Exchange plc, the Monetary Authority of Singapore or any other governmental authority other than daily limits or ranges imposed in the ordinary course by the Tokyo Stock Exchange, or (v) if a material disruption has occurred in commercial banking or securities settlement or clearance services in Japan or the United States, or with respect to Clearstream or Euroclear in Europe, or (vi) if there occurs any change or development involving a prospective change in Japanese taxation adversely affecting the Issuer, the Notes or the transfer thereof, or (vii) if a banking moratorium has been declared by any relevant authority in Japan, the United Kingdom or the United States.

(b) Liabilities

If this Agreement is terminated pursuant to this Section 10, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Section 1, Section 7, Section 8, Section 9, Section 13, Section 14, Section 15, Section 16, Section 17, Section 18, Section 20 and Section 21 hereof shall survive such termination and remain in full force and effect.

SECTION 11. Default by One or More of the Underwriters

If one or more of the Underwriters shall fail or refuse to purchase the Notes that it or they have agreed to purchase under this Agreement (the “Defaulted Notes”), the Representatives shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other Underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 36 hour period, then:

(a) if the number of Defaulted Notes does not exceed 10% of the aggregate principal amount of the Notes to be purchased hereunder, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount of the Notes constituting Defaulted Notes in the proportions

29

that their respective obligations to purchase the [series of] Notes [constituting Defaulted Notes] hereunder bear to the obligations of [such series of] the Notes of all non-defaulting Underwriters; or

(b) if the number of Defaulted Notes exceeds 10% of the aggregate principal amount of the Notes to be purchased hereunder, upon notice from the Underwriters to the Issuer, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 11 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, any of the Representatives or the Issuer shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 11.

Notices to the Underwriters shall be directed to the Representatives to [address(es)]; and notices to the Issuer shall be directed to it at 5-5, Otemachi 1-chome, Chiyoda-ku, Tokyo 100-8176, Japan, facsimile: +81 3 5224 1057, attention of Financial Planning Division.

SECTION 13. No Advisory or Fiduciary Relationship

The Issuer acknowledges and agrees that (a) the purchase and sale of the Notes pursuant to this Agreement, including the determination of the initial offering price of the Notes and any related discounts and commissions, is an arm’s-length commercial transaction among the Issuer, on the one hand, and the several Underwriters, on the other hand, (b) in connection with the offering contemplated hereby and the process leading to such transaction, each of the Underwriters is and has been acting solely as a principal and is not the agent or fiduciary of the Issuer, or any of its stockholders, creditors or employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Issuer with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Issuer on other matters) and no Underwriter has any obligation to the Issuer with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (d) the Underwriters and each of their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Issuer and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Issuer has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 15. Consent to Jurisdiction; Appointment of Agent for Service of Process; Jury Trial Waiver

(a) The Issuer irrevocably consents and agrees for the benefit of the holders of the Notes and the Underwriters that any legal action, suit or proceeding against it with respect to its obligations, liabilities or any other matter arising out of or in connection with this Agreement or the Notes may be brought in the courts of the State of New York or the courts of the United States of America located in the Borough of Manhattan, The City of New York, and any appellate court from any thereof and, until all amounts due and to become due in respect of all the Notes have been paid, or until any such legal action, suit or proceeding commenced prior to such payment has been concluded, hereby irrevocably consents and irrevocably submits to the non-exclusive jurisdiction of each such court in person and generally and unconditionally with respect to any action, suit or proceeding for itself and in respect of its properties, assets and revenues.

(b) The Issuer hereby irrevocably designates, appoints and empowers Mizuho Bank, Ltd., at its office currently located at 1271 Avenue of the Americas, New York, NY 10020, U.S.A., Attention: Managing Director, Americas Legal and Compliance Department, as its designee, appointee and agent to receive, accept and acknowledge for and on its behalf, and its properties, assets and revenues, service of any and all legal process, summons, notices and documents that may be served in any action, suit or proceeding brought against it in any such United States federal or New York state court located in the Borough of Manhattan, The City of New York, with respect to its obligations, liabilities or any other matter arising out of or in connection with this Agreement, the Notes or any additional agreement and that may be made on such designee, appointee and agent in accordance with legal procedures prescribed for such courts, it being understood and agreed that the designation, appointment and empowerment of Mizuho Bank, Ltd. as such authorized agent shall become effective immediately upon the execution of this Agreement without any further action on the part of the Issuer or any other person or entity. The Issuer represents to each Underwriter that it has notified Mizuho Bank, Ltd. of such designation, appointment and empowerment and that Mizuho Bank, Ltd. has accepted the same. If for any reason such designee, appointee and agent hereunder shall cease to be available to act as such, the Issuer agrees to designate a new designee, appointee and agent in the Borough of Manhattan, The City of New York, on the terms and for the purposes of this Section 15 satisfactory to the Representatives. The Issuer further hereby irrevocably consents and agrees to the service of any and all legal process, summons, notices and documents in any such action, suit or proceeding against it by serving a copy thereof upon the relevant agent for service of process referred to in this Section 15 (whether or not the appointment of such agent shall for any reason prove to be ineffective or such agent shall accept or acknowledge such service) or by mailing copies thereof by registered or certified air mail, postage prepaid, to it, at its address specified in or designated pursuant to this Agreement. The Issuer agrees that the failure of any such designee, appointee and agent to give any notice of such service to it shall not impair or affect in any way the validity of such service or any judgment rendered in any action or proceeding based thereon. Nothing herein shall in any way be deemed to limit the ability of the Underwriters to serve any such legal process, summons, notices and documents in any other manner permitted by applicable law or to obtain jurisdiction over the Issuer or bring actions, suits or proceedings against either of them in such other jurisdictions, and in such manner, as may be permitted by applicable law. The Issuer hereby irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of venue of any of the aforesaid actions, suits or proceedings arising out of or in connection with this Agreement or the Notes brought in the United States federal courts located in the Borough of Manhattan, The City of New York, or the courts of the State of New York located in the Borough of Manhattan, The City of New York, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. The provisions of this Section 15 shall survive any termination of this Agreement, in whole or in part.

31

(c) The Issuer hereby irrevocably waives, to the full extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 16. Waiver of Immunities

To the extent that the Issuer or any of its properties, assets or revenues may have or may hereafter become entitled to, or have attributed to them, any right of immunity, on the grounds of sovereignty, from any legal action, suit or proceeding, from set-off or counterclaim, from the jurisdiction of any court, from service of process, from attachment upon or prior to judgment, or from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any jurisdiction in which proceedings may at any time be commenced, with respect to its obligations, liabilities or any other matter under or arising out of or in connection with this Agreement, the Indenture or any additional agreement in connection with the offering, the Issuer hereby irrevocably and unconditionally, to the extent permitted by applicable law, waives and agrees not to plead or claim any such immunity and consents to such relief and enforcement.

SECTION 17. Foreign Taxes

All payments by the Issuer to each of the Underwriters hereunder shall be made free and clear of, and without deduction or withholding for or on account of, any and all present and future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereinafter imposed, levied, collected, withheld or assessed by Japan or any other jurisdiction in which the Issuer has an office from which payment is made or deemed to be made, excluding (i) any such tax imposed by reason of such Underwriter having some connection with any such jurisdiction other than its participation as the Underwriter hereunder and (ii) any income or franchise tax on the overall net income of such Underwriter imposed by the United States or any political subdivision thereof (all such non-excluded taxes, “Foreign Taxes”). If the Issuer is prevented by operation of law or otherwise from paying, causing to be paid or remitting that portion of amounts payable hereunder represented by Foreign Taxes withheld or deducted, then amounts payable under this Agreement shall, to the extent permitted by law, be increased to such amount as is necessary to yield and remit to each Underwriter an amount which, after deduction of all Foreign Taxes (including all Foreign Taxes payable on such increased payments) equals the amount that would have been payable if no Foreign Taxes applied.

SECTION 18. Judgment Currency

If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Underwriters could purchase United States dollars with such other currency in The City of New York on the New York Business Day preceding that on which final judgment is given. The obligation of the Issuer with respect to any sum due from it to the Underwriters, or any person controlling the Underwriters or any affiliate of any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first New York Business Day following receipt by such Underwriter or controlling person or affiliate of any sum in such other currency, and only to the extent that such Underwriter or controlling person or affiliate may in accordance with normal banking procedures purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person or affiliate hereunder, the Issuer agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person or affiliate against such loss, include any premiums and costs of exchange payable in connection with the purchase of, or conversion into, the relevant currency. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person or affiliate hereunder, such Underwriter or controlling person or affiliate agrees to pay to the Issuer an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person or affiliate hereunder.

32

SECTION 19. Authority of the Representative

Any action by the Underwriters hereunder may be taken by the Representatives on behalf of the Underwriters, and any such action taken by the Representatives shall be binding upon the Underwriters.

SECTION 20. Recognition of the U.S. Special Resolution Regimes

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime.

Registration Statement on Form F-3

Ladies and Gentlemen:

In connection with the registration statement (the “Registration Statement”) on Form F-3 dated the date hereof relating to debt securities (the “Debt Securities”) of Mizuho Financial Group, Inc. (the “Issuer”), we have acted as Japanese legal counsel to the Issuer and have been requested to provide our opinion to be filed as an exhibit to the Registration Statement.

For the purposes of giving this opinion, we have reviewed certified copies of the Articles of Incorporation, the Regulations of the Board of Directors, the Approval and Authorization Rules and the Regulations of the Executive Management Committee of the Issuer, and such agreements and other certificates and corporate and other records and documents of the Issuer and such other matters, documents and records, and considered such questions of the laws of Japan, as we have deemed necessary or appropriate for the purpose of rendering the opinion hereinafter set forth.

Having examined the above documents and having regard to the laws of Japan which we deem relevant, and subject to the assumptions, qualifications and limitations specified herein, we are of the opinion that:

The Debt Securities, upon the due authorization by all necessary corporate actions of the Issuer and the due execution of all necessary agreements by the respective parties, and when payment for the Debt Securities has been duly made in full, and the certificates for the Debt Securities have been duly signed by the Issuer, duly authenticated and delivered, and other necessary procedures have been completed, each in accordance with and in the manner contemplated in all related agreements, Japanese law and the Articles of Incorporation, the Regulations of the Board of Directors, the Approval and Authorization Rules and the Regulations of the Executive Management Committee of the Issuer, and assuming that the Debt Securities will constitute valid and legally binding obligations of the Issuer enforceable in accordance with their terms under their governing law, to which they are subject and as to which we render no opinion, will constitute valid and legally binding obligations of the Issuer enforceable in accordance with their terms.

We have assumed, for the purpose of rendering this opinion, that (i) all signatures or seal impressions on any documents we reviewed are true and genuine; (ii) all documents submitted to us as originals are authentic and complete; (iii) all documents submitted to us as copies are complete and conform to the originals thereof that are authentic and complete; (iv) all documents submitted to us as forms are, or will be, executed in such forms; (v) statements included, expressly or impliedly, in the documents, record and certificate of the Issuer or public officials are true and conform to the relevant facts thereof; (vi) all natural person-signatories who have executed or delivered the relevant documents on behalf of the relevant parties thereto have and had at the relevant times the sufficient and competent legal capacity to take such actions; (vii) nothing in the applicable law of any jurisdiction other than Japan would conflict with, or preclude the performance, legality, validity, effectiveness or enforcement of the Debt Securities and other relevant documents; and (viii) the Debt Securities and other relevant documents are legal, valid and binding on the parties thereto and enforceable in accordance with their respective terms under their respective governing laws (other than the laws of Japan). We have not independently verified any of the matters referred to in (i) through (viii) above.

The foregoing opinion is based on the assumptions, qualified by and subject to the limitations, set forth below:

(i) This opinion letter is strictly limited to the matters stated herein and may not be read as extending by implication to any other matters or documents not specifically referred to herein;

(ii) We are members of the bar of Japan and our opinion is limited solely to the laws of Japan in force and as interpreted as of the date hereof. In giving the opinion set forth above, we have relied, as to matters governed by the laws of the State of New York or the federal laws of the United States of America, upon the legal opinion of Simpson Thacher & Bartlett LLP, United States counsel to the Issuer dated the date hereof;

(iii) We neither express nor imply any view or opinion with regard to the requirements of any state or country other than Japan;

(iv) We express no opinion as to the availability of specific performance, injunctive relief or any other similar remedy;

(v) The opinion expressed above is subject to applicable bankruptcy, civil rehabilitation, insolvency, reorganization, fraudulent conveyance, moratorium or similar laws affecting the rights of creditors generally;

(vi) The opinion expressed above is subject to any applicable statutes of limitation, lapse of time, appropriate court procedures, the public order or policy, good morals doctrine, the good faith and fair dealing doctrine and the abuse of rights doctrine;

(vii) The opinion expressed above does not cover any matters related to tax laws, treaties, regulations or guidelines;

(viii) Certain terms used in documents referred to above or in any other document examined in connection with this opinion letter, and certain concepts expressed therein (i) may not have equivalents in the Japanese language or under Japanese legal principles, or (ii) may have a different meaning in legal practice under the governing law thereof from those understood by Japanese counsel, including ourselves, based upon the plain-English meaning of such terms or concepts, as the case may be;

(ix) In the opinion herein, Japanese legal concepts are expressed in English terms and not in their original Japanese terms. The concepts concerned may not be identical to the concept described by the equivalent English terms as they exist under the laws of other jurisdictions. We do not render any opinion as to how judges qualified in a foreign jurisdiction would interpret Japanese legal concepts or expressions, and this opinion may only be relied upon under the express condition that any issues of interpretation or liability arising thereunder will be governed by the laws of Japan and be brought before a Japanese court;

(x) We express no opinion as to any amendments, supplements, renewals, extensions or other modification of any documents referred to herein which may be made after the delivery of this opinion; and

(xi) The opinion expressed above relating to the legality, validity, effectiveness or enforceability of the obligations under any documents governed by any laws other than the laws of Japan shall mean that the laws of Japan will permit the application of the relevant governing law other than the laws of Japan to the legality, validity, effectiveness or enforceability of the obligations under such documents.

-2-

We hereby consent to the use of this opinion as an exhibit to the Registration Statement and to the use of our name under the captions “Legal Matters” and “Enforcement of Civil Liabilities” contained in the Registration Statement. In giving this consent, we do not thereby admit that we come within the category of persons whose consent is required by the U.S. Securities Act of 1933, as amended, or by the rules and regulations under it.

Exhibits 5.2 and 23.3

August 5, 2022

Mizuho Financial Group, Inc.

1-5-5 Otemachi, Chiyoda-ku

Tokyo 100-8176, Japan

Ladies and Gentlemen:

We have acted as United States counsel to Mizuho Financial Group, Inc., a joint stock corporation incorporated with limited liability under the law of Japan (the “Company”), in connection with the Registration Statement on Form F-3 (the “Registration Statement”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) under the U.S. Securities Act of 1933, as amended, relating to debt securities, which may be either senior (the “Senior Debt Securities”) or subordinated (the “Subordinated Debt Securities” and, together with the Senior Debt Securities, the “Securities”). The Securities may be issued and sold or delivered from time to time for an indeterminate aggregate initial offering price.

The Senior Debt Securities will be issued under a Senior Indenture (the “Senior Indenture”), dated as of September 13, 2016, between the Company and The Bank of New York Mellon, as trustee (the “Trustee”), and the Subordinated Debt Securities will be issued under a Subordinated Indenture (the “Subordinated Indenture” and, together with the Senior Indenture, the “Indentures”), dated as of September 13, 2021, between the Company and the Trustee.

We have examined the Registration Statement and the Indentures, each of which is an exhibit to the Registration Statement. In addition, we have examined, and have relied as to matters of fact upon, originals, or duplicates or certified or conformed copies, of such records, agreements, documents and other instruments and such certificates or comparable documents of public officials and of officers and representatives of the Company and have made such other investigations as we have deemed relevant and necessary in connection with the opinion hereinafter set forth.

In rendering the opinion set forth below, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as duplicates or certified or conformed copies, and the authenticity of the originals of such latter documents. We also have assumed that, at the time of execution, authentication, issuance and delivery of any of the Securities, the applicable Indenture will be the valid and legally binding obligation of each party thereto other than the Company.

In rendering the opinion set forth below, we have assumed further that (1) the Company is validly existing and in good standing under the law of Japan and has duly authorized, executed and delivered the Indentures in accordance with its organizational documents and the law of Japan, (2) the execution, delivery and performance by the Company of the Indentures do not constitute a breach or violation of its organizational documents or violate the law of Japan or any other jurisdiction (except that no such assumption is made with respect to the law of the State of New York) and (3) the execution, delivery and performance by the Company of the Indentures (a) do not constitute a breach or default under any agreement or instrument which is binding upon the Company and (b) comply with all applicable regulatory requirements.

Based upon the foregoing, and subject to the qualifications, assumptions and limitations stated herein, we are of the opinion that, assuming (a) the taking of all necessary corporate action by the Board of Directors of the Company, a duly constituted and acting committee of such Board of Directors or duly authorized officers of the Company (such Board of Directors, committee or authorized officers being referred to herein as the “Company Authorizing Party”) to authorize and approve the issuance and terms of any Securities and the terms of the offering thereof so as not to violate any applicable law or agreement or instrument then binding on the Company, and (b) the due execution, authentication, issuance and delivery of the Securities, upon payment therefor in

accordance with the applicable definitive underwriting, purchase or similar agreement approved by the Company Authorizing Party and otherwise in accordance with the provisions of such agreement and the applicable Indenture, such Securities will constitute valid and legally binding obligations of the Company enforceable against the Company in accordance with their terms.

Our opinion set forth above is subject to (i) the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws relating to or affecting creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law), (iii) an implied covenant of good faith and fair dealing and (iv) the effects of the possible judicial application of foreign laws or foreign governmental or judicial action affecting creditors’ rights.

In connection with the provisions of the Indentures whereby the parties submit to the jurisdiction of U.S. federal courts located in the Borough of Manhattan, The City of New York, we note the limitations of 28 U.S.C. Sections 1331 and 1332 on subject matter jurisdiction of the federal courts. In connection with the provisions of the Indentures that relate to forum selection (including, without limitation, any waiver of any objection to venue or any objection that a court is an inconvenient forum), we note that under N.Y.C.P.L.R. Section 510 a New York State court may have discretion to transfer the place of trial, and under 28 U.S.C. Section 1404(a) a United States District Court has discretion to transfer an action from one U.S. federal court to another.

In rendering the opinion set forth above, we have assumed that under the law of any jurisdiction in whose currency (or whose currency is a component currency of a composite currency in which) any Securities are denominated or payable, if other than in U.S. dollars, (A) no consent, approval, authorization, qualification or order of, or filing or registration with, any governmental agency or body or court of such jurisdiction is required for the issuance or sale of the Securities by the Company and (B) the issuance or sale of the Securities and compliance with the terms and provisions thereof will not result in a breach or violation of any of the terms or provisions of any statute, rule, regulation or order of any governmental agency or body or any court of such jurisdiction.

We note that (i) a New York State statute provides that, with respect to a foreign currency obligation, a New York State court shall render a judgment or decree in such foreign currency and such judgment or decree shall be converted into currency of the United States at the rate of exchange prevailing on the date of entry of such judgment or decree and (ii) with respect to a foreign currency obligation, a U.S. federal court sitting in New York State may award a judgment based in whole or in part in U.S. dollars, provided that we express no opinion as to the rate of exchange that such court would apply.

We do not express any opinion herein concerning any law other than the law of the State of New York and the federal law of the United States.

We hereby consent to the filing of this opinion letter as Exhibit 5.2 to the Registration Statement and to the use of our name under the caption “Legal Matters” in the prospectus included in the Registration Statement.

Very truly yours,

(1) An indeterminate amount of senior debt securities and subordinated debt securities to be offered at indeterminate prices is being registered pursuant to this registration statement. In accordance with Rules 456(b) and 457(r) under the Securities Act, the registrant is deferring payment of the registration fee. The registrant will calculate the registration fee applicable to an offering of securities pursuant to this registration statement based on the fee payment rate in effect on the date of such fee payment.

(2) This registration statement also relates to offers and sales of senior debt securities and subordinated debt securities after the initial sale of such securities in connection with market-making transactions by and through broker-dealer affiliates of Mizuho Financial Group, Inc., including Mizuho Securities USA LLC. These securities consist of an indeterminate amount of such securities that are initially being registered, and will initially be offered and sold, under this registration statement and an indeterminate amount of such securities that were initially registered, and were initially offered and sold, under registration statements previously filed by the registrant. Pursuant to Rule 457(q) under the U.S. Securities Act of 1933, as amended, no separate filing fee is required for the registration of securities to be reoffered solely for market-making purposes by an affiliate of the registrant. All such market-making reoffers and resales that are made pursuant to a registration statement after the effectiveness of this registration statement are being made solely pursuant to this registration statement.
