Item 1. Business

Overview

The CurrencyShares^® Japanese Yen Trust (the “Trust”) is a grantor trust that was formed on February 1, 2007. The Shares began trading on the New York Stock Exchange (“NYSE”) under the ticker symbol “FXY” on February 13, 2007. The primary listing of the Shares was transferred to NYSE Arca on October 30, 2007. The Trust issues shares (the “Shares”) in blocks of 50,000 (a “Basket”) in exchange for deposits of Japanese Yen and distributes Japanese Yen in connection with the redemption of Baskets.

The investment objective of the Trust is for the Shares to reflect the price of Japanese Yen plus accrued interest, if any, less the expenses of the Trust’s operations. The Shares are intended to offer investors an opportunity to participate in the market for the Japanese Yen through an investment in securities. The Shares are intended to provide institutional and retail investors with a simple, cost-effective means of gaining investment benefits similar to those of holding the Japanese Yen. The Shares are bought and sold on NYSE Arca like any other exchange-listed security. The Shares are backed by the assets of the Trust, which does not hold or use derivative products. Investing in the Shares does not insulate the investor from certain risks, including price volatility. The value of the holdings of the Trust is reported on the Trust’s website, www.currencyshares.com, each business day.

The Trust

General

The Trust holds Japanese Yen and, from time to time, issues Baskets in exchange for deposits of Japanese Yen and distributes Japanese Yen in connection with redemptions of Baskets. The Japanese Yen held by the Trust will be sold only if needed to pay Trust expenses, in the event the Trust terminates and liquidates its assets or as otherwise required by law or regulation.

The Sponsor

The Sponsor of the Trust generally oversees the performance of the Trustee and the Trust’s principal service providers, but does not exercise day-to-day oversight over the Trustee or the Trust’s service providers. The Sponsor is Guggenheim Specialized Products, LLC, a Delaware limited liability company. The Sponsor changed its name from Rydex Specialized Products LLC as of March 30, 2012.

The Trust’s only ordinary recurring expense is the Sponsor’s fee. The Sponsor is responsible for payment of the following administrative and marketing expenses of the Trust: the Trustee’s monthly fee, typical maintenance and transaction fees of the Depository, NYSE listing fees, NYSE Arca listing fees, printing and mailing costs, audit fees and expenses, up to $100,000 per year in legal fees and expenses, and applicable license fees. The Sponsor also paid the costs of the Trust’s organization, including the applicable SEC registration fees. The Sponsor’s fee accrues daily at an annual nominal rate of 0.40% of the Japanese Yen in the Trust (including all unpaid interest but excluding unpaid fees, each as accrued through the immediately preceding day). The Sponsor was paid $1,344,961 for the fiscal year ended October 31, 2012.

The Trustee

The Bank of New York Mellon, a banking corporation with trust powers organized under the laws of the State of New York, serves as the Trustee. The Trustee is responsible for the day-to-day administration of the Trust, including keeping the Trust’s operational records.

Net Asset Value

The Trustee calculates, and the Sponsor publishes, the Trust’s Net Asset Value (“NAV”) each business day. To calculate the NAV, the Trustee adds to the amount of Japanese Yen in the Trust at the end of the preceding day accrued but unpaid interest, Japanese Yen receivable under pending purchase orders and the value of other Trust assets, and subtracts the accrued but unpaid Sponsor’s fee, Japanese Yen payable under pending redemption orders and other Trust expenses and liabilities, if any. Prior to November 13, 2008, the NAV was expressed in U.S. Dollars

1

(“USD”) based on the “Noon Buying Rate,” which is the Japanese Yen/USD exchange rate as determined by the Federal Reserve Bank of New York at 12:00 PM (New York time). As of November 13, 2008, the NAV is expressed in USD based on the Japanese Yen/USD as determined by The World Markets Company PLC, a State Street business, at 4:00 PM (London fixing) (the “Closing Spot Rate”) on each day that NYSE Arca is open for regular trading. If, on a particular evaluation day, the Closing Spot Rate has not been determined and announced by 6:00 PM (London time), then the most recent Closing Spot Rate is used to determine the NAV of the Trust unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for the valuation.

The Trustee also determines the NAV per Share, which equals the NAV of the Trust, divided by the number of outstanding Shares. The NAV of the Trust and the NAV per Share are published by the Sponsor on each day that NYSE Arca is open for regular trading and is posted on the Trust’s website, www.currencyshares.com.

Depository and Deposit Accounts

JPMorgan Chase Bank, N.A., London Branch, is the Depository. The Depository maintains two deposit accounts for the Trust, a primary deposit account which is expected to earn interest and a secondary deposit account which does not earn interest (collectively, the “Deposit Accounts”). Interest on the primary deposit account, if any, accrues daily and is paid monthly. If the Sponsor believes that the interest rate paid by the Depository is not competitive, the Sponsor’s recourse is to remove the Depository by terminating the Deposit Account Agreement and closing the Deposit Accounts. The Depository is not paid a fee for its services to the Trust. The Depository may earn a “spread” or “margin” over the rate of interest it pays to the Trust on the Japanese Yen deposit balances.

The secondary deposit account is used to account for any interest that may be received and paid on creations and redemptions of Baskets. The secondary deposit account is also used to account for interest earned on the primary deposit account, if any, pay Trust expenses and distribute any excess interest to Shareholders on a monthly basis. In the event that the interest deposited exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, then the Trustee will direct that the excess be converted into USD at a prevailing market rate and the Trustee will distribute the USD as promptly as practicable to Shareholders on a pro-rata basis (in accordance with the number of Shares that they own).

Trust Expenses

In certain exceptional cases the Trust may pay expenses in addition to the Sponsor’s fee. These exceptions include expenses not assumed by the Sponsor, taxes and governmental charges, expenses and costs of any extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust or action taken by the Trustee or the Sponsor to protect the Trust or the interests of Shareholders, indemnification of the Sponsor under the Depositary Trust Agreement, and legal expenses in excess of $100,000 per year.

Termination

The Trust will terminate upon the occurrence of any of the termination events listed in the Depositary Trust Agreement and will otherwise terminate on February 1, 2047.

The Shares

General

Each Share represents a proportional interest, based on the total number of Shares outstanding, in the Japanese Yen owned by the Trust, plus accrued and unpaid interest, if any, less accrued but unpaid expenses (both asset-based and non-asset based) of the Trust. All Shares are of the same class with equal rights and privileges. Each Share is transferable, is fully paid and non-assessable and entitles the holder to vote on the limited matters upon which Shareholders may vote under the Depositary Trust Agreement.

Limited Rights

The Shares are not a traditional investment. They are dissimilar from the shares of a corporation operating a business enterprise, with management and a board of directors. Trust Shareholders do not have rights normally associated with owning shares of a business corporation, including, for example, the right to bring “oppression” or “derivative” actions. Shareholders’ have only those rights explicitly set forth in the Depositary Trust Agreement. The Shares do not entitle their holders to any conversion or pre-emptive rights or, except as described herein, any redemption or distribution rights.

2

Voting and Approvals

Shareholders have no voting rights under the Depositary Trust Agreement, except in limited circumstances. If the holders of at least 25% of the Shares outstanding determine that the Trustee is in material breach of its obligations under the Depositary Trust Agreement, they may provide written notice to the Trustee (or require the Sponsor to do so) specifying the default and requiring the Trustee to cure such default. If the Trustee fails to cure such breach within 30 days after receipt of the notice, the Sponsor, acting on behalf of the Shareholders, may remove the Trustee. The holders of at least 66 2/3% of the Shares outstanding may vote to remove the Trustee. The Trustee must terminate the Trust at the request of the holders of at least 75% of the outstanding Shares.

Creation and Redemption of Shares

The creation and redemption of Baskets requires the delivery to the Trust or the distribution by the Trust of the amount of Japanese Yen represented by the Baskets being created or redeemed. This amount is based on the combined NAV per Share of the number of Shares included in the Baskets being created or redeemed, determined on the day the order to create or redeem Baskets is accepted by the Trustee.

Only Authorized Participants may place orders to create and redeem Baskets. An Authorized Participant is a Depository Trust Company participant that is a registered broker-dealer or other securities market participant, such as a bank or other financial institution that is not required to register as a broker-dealer to engage in securities transactions.

Before initiating a creation or redemption order, an Authorized Participant must have entered into a Participant Agreement with the Sponsor and the Trustee. The Participant Agreement provides the procedures for the creation and redemption of Baskets and for the delivery of Japanese Yen required for creations and redemptions. The Participant Agreements may be amended by the Trustee and the Sponsor. Authorized Participants pay a transaction fee of $500 to the Trustee for each order that they place to create or redeem one or more Baskets. In addition to the $500 transaction fee paid to the Trustee, Authorized Participants pay a variable fee to the Sponsor for creation orders and redemption orders of two or more Baskets to compensate the Sponsor for costs associated with the registration of Shares. The variable fee paid to the Sponsor by an Authorized Participant will not exceed $2,000 for each creation or redemption order, as set forth in the Participant Agreement. Authorized Participants who make deposits with the Trust in exchange for Baskets receive no fees, commissions or other form of compensation or inducement of any kind from either the Sponsor or the Trust. No Authorized Participant has any obligation or responsibility to the Sponsor or the Trust to effect any sale or resale of Shares.

Availability of SEC Reports and Other Information

The Sponsor, on behalf of the Trust, files quarterly and annual reports and other information with the Sec. The reports and other information can be accessed through the Trust’s website at www.currencyshares.com.

ITEM 1A. Risk Factors

You should consider carefully the risks described below before making an investment decision. You should also refer to the other information included in this report, including the Trust’s financial statements and the related notes.

The value of the Shares relates directly to the value of the Japanese Yen held by the Trust. Fluctuations in the price of the Japanese Yen could materially and adversely affect the value of the Shares.

The Shares are designed to reflect the price of the Japanese Yen, plus accumulated interest, less the Trust’s expenses. Several factors may affect the price of the Japanese Yen, including:

• Sovereign debt levels and trade deficits;

• Domestic and foreign inflation rates and interest rates and investors’ expectations concerning those rates;

• Currency exchange rates;

3

• Investment and trading activities of mutual funds, hedge funds and currency funds; and

• Global or regional political, economic or financial events and situations.

In addition, the Japanese Yen may not maintain its long-term value in terms of purchasing power in the future. When the price of the Japanese Yen declines, the Sponsor expects the price of a Share to decline as well.

The USD/Japanese Yen exchange rate, like foreign exchange rates in general, can be volatile and difficult to predict. This volatility could materially and adversely affect the performance of the Shares.

Foreign exchange rates are influenced by the factors identified immediately above and may also be influenced by: changing supply and demand for a particular currency; monetary policies of governments (including exchange control programs, restrictions on local exchanges or markets and limitations on foreign investment in a country or on investment by residents of a country in other countries); changes in balances of payments and trade; trade restrictions; and currency devaluations and revaluations. Also, governments from time to time intervene in the currency markets, directly and by regulation, in order to influence prices directly. These events and actions are unpredictable. The resulting volatility in the USD/Japanese Yen exchange rate could materially and adversely affect the performance of the Shares.

The Trustee has recently withdrawn Japanese Yen from the Trust to pay expenses, reducing the amount of Japanese Yen represented by each Share and potentially resulting in adverse tax consequences for Shareholders.

Each outstanding Share represents a fractional, undivided interest in the Japanese Yen held by the Trust. Historically, the amount of interest earned by the Trust has not exceeded the Trust’s expenses; accordingly, the Trustee has been required to withdraw Japanese Yen from the Trust to pay these excess expenses. As long as the amount of interest earned does not exceed expenses, the amount of Japanese Yen represented by each Share will gradually decline. This is true even if additional Shares are issued in exchange for additional deposits of Japanese Yen into the Trust, as the amount of Japanese Yen required to create Shares will proportionately reflect the amount of Japanese Yen represented by the Shares outstanding at the time of creation. As long as the Trust’s expenses are greater than the amount of interest earned, the Shares will only maintain their original price if the price of Japanese Yen increases. There is no guarantee that interest earned by the Trust in the future will exceed the Trust’s expenses.

Investors should be aware that a gradual decline in the amount of Japanese Yen represented by the Shares may occur regardless of whether the trading price of the Shares rises or falls in response to changes in the price of Japanese Yen. The estimated ordinary operating expenses of the Trust, which accrue daily, are described in “Business — The Trust —Trust Expenses.”

The payment of expenses by the Trust will result in a taxable event to Shareholders. To the extent Trust expenses exceed interest paid to the Trust, a gain or loss may be recognized by Shareholders depending on the tax basis of the tendered Japanese Yen.

The interest rate paid by Depository, if any, may not be the best rate available. If the Sponsor determines that the interest rate is inadequate, then its sole recourse is to remove the Depository and terminate the Deposit Accounts.

The Depository is committed to endeavor to pay a competitive interest rate on the balance of Japanese Yen in the primary deposit account of the Trust, but there is no guarantee of the amount of interest that will be paid, if any, on this account. Interest on the primary deposit account, if any, accrues daily and is paid monthly. The Depository may change the rate at which interest accrues, including reducing the interest rate to zero or below zero, based upon the Depository’s belief that the Bank of Japan Overnight Call Rate does not accurately reflect the market, other market conditions or the Depository’s liquidity needs. The Depository notifies the Sponsor of the interest rate applied each business day after the close of such business day. The Sponsor discloses the current interest rate on the Trust’s website. If the Sponsor believes that the interest rate paid by the Depository is not adequate, the Sponsor’s sole recourse is to remove the Depository and terminate the Deposit Accounts. The Depository is not paid a fee for its services to the Trust; rather, it generates income or loss based on its ability to earn a “spread” or “margin” over the interest it pays to the Trust by using the Trust’s Japanese Yen to make loans or in other banking operations. For these reasons, you should not expect that the Trust will be paid the best available interest rate at any time or over time.

4

If the Trust incurs expenses in USD, the Trust would be required to sell Japanese Yen to pay these expenses. The sale of the Trust’s Japanese Yen to pay expenses in USD at a time of low Japanese Yen prices could adversely affect the value of the Shares.

The Trustee will sell Japanese Yen held by the Trust to pay Trust expenses, if any, incurred in USD, irrespective of then-current Japanese Yen prices. The Trust is not actively managed and no attempt will be made to buy or sell Japanese Yen to protect against or to take advantage of fluctuations in the price of the Japanese Yen. Consequently, if the Trust incurs expenses in USD, the Trust’s Japanese Yen may be sold at a time when the Japanese Yen price is low, resulting in a negative effect on the value of the Shares.

The Deposit Accounts are not entitled to payment at any office of JPMorgan Chase Bank, N.A. located in the United States.

The federal laws of the United States prohibit banks located in the United States from paying interest on unrestricted demand deposit accounts. Therefore, payments out of the Deposit Accounts will be payable only at the London branch of JPMorgan Chase Bank, N.A., located in England. The Trustee will not be entitled to demand payment of these accounts at any office of JPMorgan Chase Bank, N.A. that is located in the United States. JPMorgan Chase Bank, N.A. will not be required to repay the deposit if its London branch cannot repay the deposit due to an act of war, insurrection or civil strife or an action by a foreign government or instrumentality (whether de jure or de facto) in England.

Shareholders do not have the protections associated with ownership of a demand deposit account insured in the United States by the Federal Deposit Insurance Corporation nor the protection provided for bank deposits under English law.

Neither the Shares nor the Deposit Accounts and the Japanese Yen deposited in them are deposits insured against loss by the FDIC, any other federal agency of the United States or the Financial Services Compensation Scheme of England.

If the Depository becomes insolvent, its assets might not be adequate to satisfy a claim by the Trust or any Authorized Participant. In addition, in the event of the insolvency of the Depository, the U.S. bank of which it is a branch or any local cash correspondent holding the currency on deposit for the benefit of the Trust, there may be a delay and costs incurred in recovering the Japanese Yen held in the Deposit Accounts.

Japanese Yen deposited in the Deposit Accounts by an Authorized Participant are commingled with Japanese Yen deposited by other Authorized Participants and are held by the Depository in either the primary deposit account or the secondary deposit account of the Trust. Japanese Yen held in the Deposit Accounts are not segregated from the Depository’s other assets.

The Trust has no proprietary rights in or to any specific Japanese Yen held by the Depository and will be an unsecured creditor of the Depository with respect to the Japanese Yen held in the Deposit Accounts in the event of the insolvency of the Depository or the U.S. bank of which it is a branch. In the event the Depository, the U.S. bank of which it is a branch or any local cash correspondent holding the currency on deposit for the benefit of the Trust becomes insolvent, the Depository’s assets might not be adequate to satisfy a claim by the Trust or any Authorized Participant for the amount of Japanese Yen deposited by the Trust or the Authorized Participant and, in such event, the Trust and any Authorized Participant will generally have no right in or to assets other than those of the Depository.

In the case of insolvency of the Depository or JPMorgan Chase Bank, N.A., the U.S. bank of which the Depository is a branch, a liquidator may seek to freeze access to the Japanese Yen held in all accounts by the Depository, including the Deposit Accounts. In the case of insolvency of a local cash correspondent, a liquidator may seek to freeze access to the Japanese Yen held in all accounts by such local cash correspondent, including the Deposit Accounts held by such cash correspondent. The Trust and the Authorized Participants could incur expenses and delays in connection with asserting their claims. These problems would be exacerbated by the fact that the Deposit Accounts are not held in the U.S. but instead are held at the London branch of a U.S. national bank or with a local cash correspondent, where they are subject to English and Japanese insolvency law. Further, under U.S. law, in the case of the insolvency of JPMorgan Chase Bank, N.A., the claims of creditors in respect of accounts (such as the Trust’s Deposit Accounts) that are maintained with an overseas branch of JPMorgan Chase Bank, N.A. or with a local cash correspondent will be subordinate to claims of creditors in respect of accounts maintained with JPMorgan Chase Bank, N.A. in the U.S., greatly increasing the risk that the Trust and the Trust’s beneficiaries would suffer a loss.

5

Shareholders do not have the protections associated with ownership of shares in an investment company registered under the Investment Company Act.

The Investment Company Act is designed to protect investors by preventing insiders from managing investment companies to their benefit and to the detriment of public investors; the issuance of securities having inequitable or discriminatory provisions; the management of investment companies by irresponsible persons; the use of unsound or misleading methods of computing earnings and asset value; changes in the character of investment companies without the consent of investors; and investment companies from engaging in excessive leveraging. To accomplish these ends, the Investment Company Act requires the safekeeping and proper valuation of fund assets, restricts greatly transactions with affiliates, limits leveraging, and imposes governance requirements as a check on fund management.

The Trust is not registered as an investment company under the Investment Company Act and is not required to register under that act. Consequently, Shareholders do not have the regulatory protections afforded to investors in registered investment companies.

Shareholders do not have the rights enjoyed by investors in certain other financial instruments.

As interests in a grantor trust, the Shares have none of the statutory rights normally associated with the ownership of shares of a business corporation, including, for example, the right to bring “oppression” or “derivative” actions. Apart from the rights afforded to them by federal and state securities laws, Shareholders have only those rights relative to the Trust, the Trust property and the Shares that are set forth in the Depositary Trust Agreement. In this connection, the Shareholders have limited voting and distribution rights. They do not have the right to elect directors. See “Business – The Shares – Limited Rights” for a description of the limited rights of the Shareholders.

The Shares may trade at a price which is at, above, or below the NAV per Share.

The NAV per Share fluctuates with changes in the market value of the Trust’s assets. The market price of Shares can be expected to fluctuate in accordance with changes in the NAV per Share, but also in response to market supply and demand. As a result, the Shares might trade at prices at, above or below the NAV per Share.

The Depository owes no fiduciary duties to the Trust or the Shareholders, is not required to act in their best interest and could resign or be removed by the Sponsor, which would trigger early termination of the Trust.

The Depository is not a trustee for the Trust or the Shareholders. As stated above, the Depository is not obligated to maximize the interest rate paid to the Trust. In addition, the Depository has no duty to continue to act as the depository of the Trust. The Depository can terminate its role as depository for any reason whatsoever upon 90 days’ notice to the Trust. If directed by the Sponsor, the Trustee must terminate the Depository. Such a termination might result, for example, if the Sponsor determines that the interest rate paid by the Depository is inadequate. In the event that the Depository was to resign or be removed, the Trust will be terminated.

Shareholders may incur significant fees upon the termination of the Trust.

The occurrence of any one of several events would either require the Trust to terminate or permit the Sponsor to terminate the Trust. For example, if the Depository were to resign or be removed, then the Sponsor would be required to terminate the Trust. Shareholders tendering their Shares within 90 days of the Trust’s termination will receive the amount of Japanese Yen represented by their Shares. Shareholders may incur significant fees if they choose to convert the Japanese Yen they receive to USD.

Redemption orders are subject to rejection by the Trustee under certain circumstances.

The Trustee will reject a redemption order if the order is not in proper form as described in the Participant Agreement or if the fulfillment of the order, in the opinion of its counsel, might be unlawful. Any such rejection could adversely affect a redeeming Shareholder. For example, the resulting delay would adversely affect the value of the Shareholder’s redemption distribution if the NAV were to decline during the delay. In the Depositary Trust Agreement, the Sponsor and the Trustee disclaim any liability for any loss or damage that may result from any such rejection.

6

Substantial sales of Japanese Yen by the official sector could adversely affect an investment in the Shares.

The official sector consists of central banks, other governmental agencies and multi-lateral institutions that buy, sell and hold Japanese Yen as part of their reserve assets. The official sector holds a significant amount of Japanese Yen that can be mobilized in the open market. In the event that future economic, political or social conditions or pressures require members of the official sector to sell their Japanese Yen simultaneously or in an uncoordinated manner, the demand for Japanese Yen might not be sufficient to accommodate the sudden increase in the supply of Japanese Yen to the market. Consequently, the price of the Japanese Yen could decline, which would adversely affect an investment in the Shares.

Shareholders that are not Authorized Participants may only purchase or sell their Shares in secondary trading markets.

Only Authorized Participants may create or redeem Baskets through the Trust. All other investors that desire to purchase or sell Shares must do so through NYSE Arca or in other markets, if any, in which the Shares are traded.

The liability of the Sponsor and the Trustee under the Depositary Trust Agreement is limited and, except as set forth in the Depositary Trust Agreement, they are not obligated to prosecute any action, suit or other proceeding in respect of any Trust property.

The Depositary Trust Agreement provides that neither the Sponsor nor the Trustee assumes any obligation or is subject to any liability under the Trust Agreement to any Shareholder, except that they each agree to perform their respective obligations specifically set forth in the Depositary Trust Agreement without negligence or bad faith. Additionally, neither the Sponsor nor the Trustee is obligated to, although each may in its respective discretion, prosecute any action, suit or other proceeding in respect of any Trust property. The Depositary Trust Agreement does not confer upon Shareholders the right to prosecute any such action, suit or other proceeding.

The Depositary Trust Agreement may be amended to the detriment of Shareholders without their consent.

The Sponsor and the Trustee may amend most provisions (other than those addressing core economic rights) of the Depositary Trust Agreement without the consent of any Shareholder. Such an amendment could impose or increase fees or charges borne by the Shareholders. Any amendment that increases fees or charges (other than taxes and other governmental charges, registration fees or other expenses), or that otherwise prejudices any substantial existing rights of Shareholders, will not become effective until 30 days after written notice is given to Shareholders.

The License Agreement with The Bank of New York Mellon may be terminated by The Bank of New York Mellon in the event of a material breach. Termination of the License Agreement might lead to early termination and liquidation of the Trust.

The Bank of New York Mellon and an affiliate of the Sponsor have entered into a License Agreement granting the Sponsor’s affiliate a license to certain patent applications made by The Bank of New York Mellon covering systems and methods for securitizing a commodity. The Sponsor’s affiliate has sublicensed the license to the Sponsor. The license is limited to a non-exclusive grant for the life of The Bank of New York Mellon’s patents and patent applications. The License Agreement provides that each of the parties may provide notice of intent to terminate the License Agreement in the event the other party commits a material breach. If the License Agreement is terminated and one or more of The Bank of New York Mellon’s patent applications issue as patents, then The Bank of New York Mellon may claim that the operation of the Trust violates its patent or patents and seek an injunction forcing the Trust to cease operation and the Shares to cease trading. In that case, the Trust might be forced to terminate and liquidate, which would adversely affect Shareholders.

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as “anticipate,” “expect,” “intend,” “plan,” “believe,” “seek,” “outlook” and “estimate” and other similar words. Forward-looking statements are based upon our current expectations and beliefs concerning future developments and their potential effects on us. Such forward-looking statements are not guarantees of future performance. Various factors may cause our actual results to differ materially from those expressed in our forward-looking statements. These factors include fluctuations in the price of the Japanese Yen, as the value of the Shares relates directly to the value of the Japanese Yen held by the Trust and price fluctuations could materially adversely affect an investment in the Shares. Readers are urged to review the “Risk Factors” section in this report for a description of other risks and uncertainties that may affect an investment in the Shares.

Neither Guggenheim Specialized Products, LLC d/b/a Guggenheim Investments (the “Sponsor”) nor any other person assumes responsibility for the accuracy or completeness of forward-looking statements contained in this report. The forward-looking statements are made as of the date of this report, and will not be revised or updated to reflect actual results or changes in the Sponsor’s expectations or predictions.

Movements in the Price of Japanese Yen

The investment objective of the Trust is for the Shares to reflect the price of the Japanese Yen plus accrued interest, less the expenses of the Trust’s operations. The Shares are intended to provide institutional and retail investors with a simple, cost-effective means of gaining investment benefits similar to those of holding Japanese Yen. Each outstanding Share represents a proportional interest in the Japanese Yen held by the Trust. The following chart provides recent trends on the price of Japanese Yen. The chart illustrates movements in the price of Japanese Yen in USD and is based on the Noon Buying Rate (prior to November 13, 2008) and the Closing Spot Rate (as of and after November 13, 2008).

NAV per Share; Valuation of the Japanese Yen

The following chart illustrates the movement in the price of the Shares based on (1) NAV per Share, (2) the “bid” and “ask” midpoint offered on the NYSE (prior to October 30, 2007) and NYSE Arca (on or after October 30, 2007) and (3) the Noon Buying Rate (prior to November 13, 2008) and the Closing Spot Rate (as of and after November 13, 2008), expressed as a multiple of 10,000 Japanese Yen.

Liquidity

The Sponsor is not aware of any trends, demands, conditions or events that are reasonably likely to result in material changes to the Trust’s liquidity needs. The Trust’s Depository, JPMorgan Chase Bank, N.A., London Branch, maintains two deposit accounts for the Trust, a primary deposit account which is expected to earn interest and a secondary deposit account which does not earn interest. Interest on the primary deposit account, if any, accrues daily and is paid monthly. The interest rate in effect as of October 31, 2012 was an annual nominal rate of 0%. The following chart provides the daily rate paid by the Depository since the Shares began trading:

In exchange for a fee, the Sponsor bears most of the expense incurred by the Trust. As a result, the only ordinary expense of the Trust during the periods covered by this report was the Sponsor’s fee. Each month the Depository deposits into the secondary deposit account accrued but unpaid interest, if any, and the Trustee withdraws Japanese Yen from the secondary deposit account to pay the accrued Sponsor’s fee for the previous month plus other Trust expenses, if any. When the interest deposited, if any, exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trustee converts the excess into USD at a prevailing market rate and distributes the USD as promptly as practicable to Shareholders on a pro-rata basis (in accordance with the number of Shares that they own). To date, the Trust has not made any distributions.

Critical Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Sponsor’s management to make estimates and assumptions that affect the reported amounts of the assets and liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period covered by this report.

In addition to the description below, please refer to Note 2 to the consolidated financial statements for further discussion of our accounting policies.

The functional currency of the Trust is the Japanese Yen in accordance with ASC 830, Foreign Currency Translation.

Results of Operations

As of October 31, 2010, the number of Japanese Yen owned by the Trust was 18,803,479,994, resulting in a redeemable capital share value of $233,348,012. During the year ended October 31, 2011, an additional 9,000,000 shares were created in exchange for 88,793,945,166 Japanese Yen and 5,700,000 shares were redeemed in exchange for 56,278,620,069 Japanese Yen. In addition, 65,679,396 Japanese Yen were withdrawn to pay the portion of sponsor fee that exceeded the interest earned. As of October 31, 2011, the number of Japanese Yen owned by the Trust was 51,253,125,695, resulting in a redeemable capital share value of $657,092,957. During the year ended October 31, 2012, an additional 5,050,000 shares were created in exchange for 49,684,003,600 Japanese Yen and 9,200,000 shares were redeemed in exchange for 90,510,599,952 Japanese Yen. In addition, 118,087,857 Japanese Yen were withdrawn to pay the portion of sponsor fee that exceeded the interest earned. As of October 31, 2012, the number of Japanese Yen owned by the Trust was 10,308,441,486, resulting in a redeemable capital share value of $128,920,251.

A decrease in the Trust’s redeemable capital share value from $657,092,957 at October 31, 2011 to $128,920,251 at October 31, 2012, was primarily the result of a decrease in the number of Shares outstanding from 5,200,000 at October 31, 2011 to 1,050,000 at October 31, 2012 and a decrease in the Closing Spot Rate from 0.012825 at October 31, 2011 to 0.012511 at October 31, 2012. An increase in the Trust’s redeemable capital share value from $233,348,012 at October 31, 2010 to $657,092,957 at October 31, 2011, was primarily the result of an increase in the number of Shares outstanding from 1,900,000 at October 31, 2010 to 5,200,000 at October 31, 2011 and an increase in the Closing Spot Rate from .012415 at October 31, 2010 to .012825 at October 31, 2011.

No interest income was earned during the years ended October 31, 2012, October 31, 2011 and October 31, 2010, due to an annual nominal interest rate of 0.00% through those periods as set forth in the chart above.

The Sponsor’s fee accrues daily at an annual nominal rate of 0.40% of the Japanese Yen in the Trust. Due primarily to an increase in the weighted-average Japanese Yen in the Trust, the Sponsor’s fee increased from $935,531 for the year ended October 31, 2011 to $1,344,961 for the year ended October 31, 2012. The only expense of the Trust during the year ended October 31, 2012 was the Sponsor’s fee. Due primarily to a decrease in the weighted-average Japanese Yen in the Trust, the Sponsor’s fee decreased from $1,137,346 for the year ended October 31, 2010 to $935,531 for the year ended October 31, 2011. The only expense of the Trust during the year ended October 31, 2011 was the Sponsor’s fee.

The Trust’s net loss for the year ended October 31, 2012 was $1,344,961 as a result of the Sponsor’s fee of $1,344,961 exceeding interest income of $0. The Trust’s net loss for the year ended October 31, 2011 was $935,531 due to the Sponsor’s fee of $935,531 exceeding interest income of $0. The Trust’s net loss for the year ended October 31, 2010 was $1,137,346 as a result of the Sponsor’s fee of $1,137,346 exceeding interest income of $0.

Cash dividends were not paid by the Trust in the years ended October 31, 2012, October 31, 2011 and October 31, 2010, as the Trust’s interest income did not exceed the Trust’s expenses during those periods.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The chief executive officer and chief financial officer of the Sponsor have evaluated the effectiveness of the Trust’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of October 31, 2012. Based on that evaluation, the chief executive officer and chief financial officer of the Sponsor have concluded that the disclosure controls and procedures of the Trust were effective as of the end of the period covered by this annual report.

Management’s Report on Internal Control over Financial Reporting

The Sponsor’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined under Rules 13a-15(f) and 15d-15(f) of the Exchange Act. The Trust’s internal control over financial reporting is based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Trust’s assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that the Trust’s receipts and expenditures are being made only in accordance with appropriate authorizations; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Trust’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become ineffective because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate.

The chief executive officer and chief financial officer of the Sponsor have assessed the effectiveness of the Trust’s internal control over financial reporting as of October 31, 2012. Their assessment included an evaluation of the design of the Trust’s internal control over financial reporting and testing of the operation effectiveness of its internal controls over financial reporting. Based on their assessment and those criteria, the chief executive officer and chief financial officer of the Sponsor believe that the Trust maintained effective internal control over financial reporting as of October 31, 2012.

Effectiveness of the Trust’s internal control over financial reporting as of October 31, 2012 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report included herein.

Changes in Internal Control over Financial Reporting

There were no changes in the Trust’s internal control over financial reporting that occurred during the Trust’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Trust’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders of CurrencyShares^® Japanese Yen Trust:

We have audited the accompanying statements of financial condition of CurrencyShares^® Japanese Yen Trust (the “Trust”) as of October 31, 2012 and 2011, and the related statements of income and comprehensive income, changes in shareholders' equity, and cash flows for each of the three years in the period ended October 31, 2012. These financial statements are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of CurrencyShares^® Japanese Yen Trust at October 31, 2012 and 2011, and the results of its operations and its cash flows for each of the three years in the period ended October 31, 2012, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), CurrencyShares^® Japanese Yen Trust's internal control over financial reporting as of October 31, 2012, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated January 14, 2013 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

To the Shareholders of CurrencyShares^® Japanese Yen Trust:

We have audited CurrencyShares^® Japanese Yen Trust’s (the “Trust”) internal control over financial reporting as of October 31, 2012, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). The Trust’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting appearing under Item 9A. Our responsibility is to express an opinion on the Trust’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, CurrencyShares^® Japanese Yen Trust maintained, in all material respects, effective internal control over financial reporting as of October 31, 2012, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the statements of financial condition as of October 31, 2012 and 2011, and the related statements of income and comprehensive income, changes in shareholders’ equity and cash flows for each of the three years in the period ended October 31, 2012 of CurrencyShares^® Japanese Yen Trust and our report dated January 14, 2013, expressed an unqualified opinion thereon.

CurrencyShares^® Japanese Yen Trust

Notes to Financial Statements

1. Organization and Description of the Trust

The CurrencyShares^® Japanese Yen Trust (the “Trust”) was formed under the laws of the State of New York on February 1, 2007 when Guggenheim Specialized Products, LLC d/b/a “Guggenheim Investments” (the “Sponsor”) deposited 10,000 Japanese Yen in the Trust’s primary deposit account held by JPMorgan Chase Bank, N.A., London Branch (the “Depository”). The Sponsor is a Delaware limited liability company whose sole member is Security Investors, LLC (also d/b/a “Guggenheim Investments”). The Sponsor is responsible for, among other things, overseeing the performance of The Bank of New York Mellon (the “Trustee”) and the Trust’s principal service providers, including the preparation of financial statements. The Trustee is responsible for the day-to-day administration of the Trust.

The investment objective of the Trust is for the Trust’s shares (the “Shares”) to reflect the price of the Japanese Yen plus accrued interest less the Trust’s expenses and liabilities. The Shares are intended to provide investors with a simple, cost-effective means of gaining investment benefits similar to those of holding Japanese Yen. The Trust’s assets primarily consist of Japanese Yen on demand deposit in two deposit accounts maintained by the Depository: a primary deposit account which may earn interest and a secondary deposit account which does not earn interest. The secondary deposit account is used to account for any interest that may be received and paid out on creations and redemptions of blocks of 50,000 Shares (“Baskets”). The secondary account is also used to account for interest earned, if any, on the primary deposit account, pay Trust expenses and distribute any excess interest to holders of Shares (“Shareholders”) on a monthly basis.

The accompanying audited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America.

2. Significant Accounting Policies

A. Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of the assets, liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period and the evaluation of subsequent events through the issuance date of the financial statements. Actual results could differ from those estimates.

B. Foreign Currency Translation

The Trustee calculates the Trust’s net asset value (“NAV”) each business day, as described in Note 4. As of November 13, 2008, Japanese Yen deposits (cash) are translated for NAV calculation purposes at the Closing Spot Rate, which is the USD/Japanese Yen exchange rate as determined by The World Markets Company PLC, a State Street business, at 4:00 PM (London fixing) on each day that NYSE Arca is open for regular trading.

The functional currency of the Trust is the Japanese Yen in accordance with generally accepted accounting standards. For financial statement reporting purposes, the U.S. Dollar is the reporting currency. As a result, the financial records of the Trust are translated from Japanese Yen to USD. The Closing Spot Rate on the last day of the period is used for translation in the statements of financial condition. The average Closing Spot Rate for the period is used for translation in the statements of income and comprehensive income and the statements of cash flows. Any currency translation adjustment is included in comprehensive income.

C. Federal Income Taxes

The Trust is treated as a “grantor trust” for federal income tax purposes and, therefore, no provision for federal income taxes is required. Interest, gains and losses are passed through to the Shareholders.

F-8

Shareholders generally will be treated, for U.S. federal income tax purposes, as if they directly owned a pro-rata share of the assets held in the Trust. Shareholders also will be treated as if they directly received their respective pro-rata portion of the Trust’s income, if any, and as if they directly incurred their respective pro-rata portion of the Trust’s expenses. The acquisition of Shares by a U.S. Shareholder as part of a creation of a Basket will not be a taxable event to the Shareholder.

The Sponsor’s fee accrues daily and is payable monthly. For U.S. federal income tax purposes, an accrual-basis U.S. Shareholder generally will be required to take into account as an expense its allocable portion of the USD-equivalent of the amount of the Sponsor’s fee that is accrued on each day, with such USD-equivalent being determined by the currency exchange rate that is in effect on the respective day. To the extent that the currency exchange rate on the date of payment of the accrued amount of the Sponsor’s fee differs from the currency exchange rate in effect on the day of accrual, the U.S. Shareholder will recognize a currency gain or loss for U.S. federal income tax purposes.

The Trust does not expect to generate taxable income except for interest income (if any) and gain (if any) upon the sale of Japanese Yen. A non-U.S. Shareholder generally will not be subject to U.S. federal income tax with respect to gain recognized upon the sale or other disposition of Shares, or upon the sale of Japanese Yen by the Trust, unless: (1) the non-U.S. Shareholder is an individual and is present in the United States for 183 days or more during the taxable year of the sale or other disposition, and the gain is treated as being from United States sources; or (2) the gain is effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

A non-U.S. Shareholder’s portion of any interest income earned by the Trust generally will not be subject to U.S. federal income tax unless the Shares owned by such non-U.S. Shareholder are effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

D. Revenue Recognition

Interest on the primary deposit account, if any, accrues daily as earned and is received on a monthly basis.

E. Dividends

To the extent that the interest earned by the Trust exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trust will distribute, as a dividend (herein referred to as dividends or distributions), the excess interest earned in Japanese Yen effective on the first business day of the subsequent month. The Trustee will direct that the excess Japanese Yen be converted into USD at the prevailing market rate and the Trustee will distribute the USD as promptly as practicable to Shareholders on a pro-rata basis (in accordance with the number of Shares that they own).

3. Japanese Yen Deposits

Japanese Yen principal deposits are held in a Japanese Yen -denominated, interest-bearing demand account. The interest rate in effect as of October 31, 2012 was an annual nominal rate of 0%. For the year ended October 31, 2012, there were Japanese Yen principal deposits of 49,684,003,600, Japanese Yen principal redemptions of 90,510,599,952 and Japanese Yen withdrawals (to pay expenses) of 118,087,857, resulting in an ending Japanese Yen principal balance of 10,308,441,486. This equates to 128,968,366 USD. For the year ended October 31, 2011, there were Japanese Yen principal deposits of 88,793,945,166, Japanese Yen principal redemptions of 56,278,620,069 and Japanese Yen withdrawals (to pay expenses) of 65,679,396 resulting in an ending Japanese Yen principal balance of 51,253,125,695. This equates to 657,302,029 USD (which includes USD subscriptions receivable and USD redemptions payable). For the year ended October 31, 2010, there were Japanese Yen principal deposits of 39,143,674,136, Japanese Yen principal redemptions of 56,996,238,776 and Japanese Yen withdrawals (to pay expenses) of 108,016,272 resulting in an ending Japanese Yen principal balance of 18,803,479,994. This equates to 233,438,609 USD (which includes USD subscriptions receivable and USD redemptions payable).

Net interest, if any, associated with creation and redemption activity is held in a Japanese Yen-denominated non-interest-bearing account, and any balance is distributed in full as part of the monthly income distributions, if any.

F-9

4. Redeemable Capital Shares

Shares are classified as “redeemable” for financial statement purposes, since they are subject to redemption. Shares are issued and redeemed continuously in Baskets in exchange for Japanese Yen. Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. Only Authorized Participants (as defined below) may place orders to create and redeem Baskets. An Authorized Participant is a Depository Trust Company (“DTC”) participant that is a registered broker-dealer or other institution eligible to settle securities transactions through the book-entry facilities of DTC and which has entered into a contractual arrangement with the Trust and the Sponsor governing, among other matters, the creation and redemption process. Authorized Participants may redeem their Shares at any time in Baskets.

Due to expected continuing creations and redemptions of Baskets and the three-day period for settlement of each creation or redemption, the Trust reflects Shares created as a receivable. Shares redeemed are reflected as a liability on the trade date. Outstanding Shares are reflected at a redemption value, which is the NAV per Share at the period end date. Adjustments to redeemable capital Shares at redemption value are recorded against retained earnings or, in the absence of retained earnings, by charges against the cumulative translation adjustment.

Activity in redeemable capital Shares is as follows:

	Year ended October 31, 2012						Year ended October 31, 2011						Year ended October 31, 2010
	Shares			U.S. Dollar Amount			Shares			U.S. Dollar Amount			Shares			U.S. Dollar Amount
Opening balance		5,200,000		$	657,092,957			1,900,000		$	233,348,012			3,700,000		$	405,985,408
Shares issued		5,050,000			628,647,246			9,000,000			1,101,865,545			3,950,000			440,351,417
Shares redeemed		(9,200,000	)		(1,145,222,513	)		(5,700,000	)		(698,375,010	)		(5,750,000	)		(641,185,966	)
Adjustment to period Shares due to currency movement and other		—			(11,597,439	)		—			20,254,410			—			28,197,153
Ending balance		1,050,000		$	128,920,251			5,200,000		$	657,092,957			1,900,000		$	233,348,012

The Trustee calculates the Trust’s NAV each business day. To calculate the NAV, the Trustee subtracts the Sponsor’s accrued fee through the previous day from the Japanese Yen held by the Trust (including all unpaid interest accrued, if any, through the preceding day) and calculates the value of the Japanese Yen in USD based upon the Closing Spot Rate. If, on a particular evaluation day, the Closing Spot Rate has not been determined and announced by 6:00 PM (London time), then the most recent Closing Spot Rate will be used to determine the NAV of the Trust unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for the valuation. If the Trustee and the Sponsor determine that the most recent Closing Spot Rate is not an appropriate basis for valuation of the Trust’s Japanese Yen, they will determine an alternative basis for the valuation. The Trustee also determines the NAV per Share, which equals the NAV of the Trust divided by the number of outstanding Shares. Shares deliverable under a purchase order are considered outstanding for purposes of determining NAV per Share; Shares deliverable under a redemption order are not considered outstanding for this purpose.

F-11

6. Sponsor’s Fee

The Sponsor’s fee accrues daily at an annual nominal rate of 0.40% of the Japanese Yen in the Trust (including all unpaid interest but excluding unpaid fees, each as accrued through the immediately preceding day) and is paid monthly.

The Sponsor assumes and pays the following administrative and marketing expenses incurred by the Trust: the Trustee’s monthly fee, NYSE Arca listing fees, SEC registration fees, typical maintenance and transaction fees of the Depository, printing and mailing costs, audit fees and expenses, up to $100,000 per year in legal fees and expenses, and applicable license fees.

In certain exceptional cases the Trust will pay for some expenses in addition to the Sponsor’s fee. These exceptions include expenses not assumed by the Sponsor (i.e., expenses other than those identified in the preceding paragraph), taxes and governmental charges, expenses and costs of any extraordinary services performed by the Trustee or the Sponsor on behalf of the Trust or action taken by the Trustee or the Sponsor to protect the Trust or the interests of Shareholders, indemnification of the Sponsor under the Depositary Trust Agreement, and legal expenses in excess of $100,000 per year.

7. Related Parties

The Sponsor is a related party of the Trust. The Sponsor oversees the performance of the Trustee and the Trust’s principal service providers, including the preparation of financial statements, but does not exercise day-to-day oversight over the Trustee or the Trust’s service providers.

8. Concentration Risk

All of the Trust’s assets are Japanese Yen, which creates a concentration risk associated with fluctuations in the price of the Japanese Yen. Accordingly, a decline in the Japanese Yen to USD exchange rate will have an adverse effect on the value of the Shares. Factors that may have the effect of causing a decline in the price of the Japanese Yen include national debt levels and trade deficits, domestic and foreign inflation rates, domestic and foreign interest rates, investment and trading activities of institutions and global or regional political, economic or financial events and situations. Substantial sales of Japanese Yen by the official sector (central banks, other governmental agencies and related institutions that buy, sell and hold Japanese Yen as part of their reserve assets) could adversely affect an investment in the Shares.

All of the Trust’s Japanese Yen are held by the Depository. Accordingly, a risk associated with the concentration of the Trust’s assets in accounts held by a single financial institution exists and increases the potential for loss by the Trust and the Trust’s beneficiaries in the event that the Depository becomes insolvent.

9. Commitments and Contingencies

Under the Trust’s organizational documents, the Sponsor is indemnified against any liability or expense it incurs without negligence, bad faith or willful misconduct on its part. The Trust’s maximum exposure under this arrangement is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred.

Japanese Yen principal deposits are held in a Japanese Yen -denominated, interest-bearing demand account. The interest rate in effect as of October 31, 2012 was an annual nominal rate of 0%. For the year ended October 31, 2012, there were Japanese Yen principal deposits of 49,684,003,600, Japanese Yen principal redemptions of 90,510,599,952 and Japanese Yen withdrawals (to pay expenses) of 118,087,857, resulting in an ending Japanese Yen principal balance of 10,308,441,486. This equates to 128,968,366 USD. For the year ended October 31, 2011, there were Japanese Yen principal deposits of 88,793,945,166, Japanese Yen principal redemptions of 56,278,620,069 and Japanese Yen withdrawals (to pay expenses) of 65,679,396 resulting in an ending Japanese Yen principal balance of 51,253,125,695.

Significant Accounting Policies [Abstract]

Significant Accounting Policies

2. Significant Accounting Policies

A. Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of the assets, liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period and the evaluation of subsequent events through the issuance date of the financial statements. Actual results could differ from those estimates.

B. Foreign Currency Translation

The Trustee calculates the Trust’s net asset value (“NAV”) each business day, as described in Note 4. As of November 13, 2008, Japanese Yen deposits (cash) are translated for NAV calculation purposes at the Closing Spot Rate, which is the USD/Japanese Yen exchange rate as determined by The World Markets Company PLC, a State Street business, at 4:00 PM (London fixing) on each day that NYSE Arca is open for regular trading.

The functional currency of the Trust is the Japanese Yen in accordance with generally accepted accounting standards. For financial statement reporting purposes, the U.S. Dollar is the reporting currency. As a result, the financial records of the Trust are translated from Japanese Yen to USD. The Closing Spot Rate on the last day of the period is used for translation in the statements of financial condition. The average Closing Spot Rate for the period is used for translation in the statements of income and comprehensive income and the statements of cash flows. Any currency translation adjustment is included in comprehensive income.

C. Federal Income Taxes

The Trust is treated as a “grantor trust” for federal income tax purposes and, therefore, no provision for federal income taxes is required. Interest, gains and losses are passed through to the Shareholders.

Shareholders generally will be treated, for U.S. federal income tax purposes, as if they directly owned a pro-rata share of the assets held in the Trust. Shareholders also will be treated as if they directly received their respective pro-rata portion of the Trust’s income, if any, and as if they directly incurred their respective pro-rata portion of the Trust’s expenses. The acquisition of Shares by a U.S. Shareholder as part of a creation of a Basket will not be a taxable event to the Shareholder.

The Sponsor’s fee accrues daily and is payable monthly. For U.S. federal income tax purposes, an accrual-basis U.S. Shareholder generally will be required to take into account as an expense its allocable portion of the USD-equivalent of the amount of the Sponsor’s fee that is accrued on each day, with such USD-equivalent being determined by the currency exchange rate that is in effect on the respective day. To the extent that the currency exchange rate on the date of payment of the accrued amount of the Sponsor’s fee differs from the currency exchange rate in effect on the day of accrual, the U.S. Shareholder will recognize a currency gain or loss for U.S. federal income tax purposes.

The Trust does not expect to generate taxable income except for interest income (if any) and gain (if any) upon the sale of Japanese Yen. A non-U.S. Shareholder generally will not be subject to U.S. federal income tax with respect to gain recognized upon the sale or other disposition of Shares, or upon the sale of Japanese Yen by the Trust, unless: (1) the non-U.S. Shareholder is an individual and is present in the United States for 183 days or more during the taxable year of the sale or other disposition, and the gain is treated as being from United States sources; or (2) the gain is effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

A non-U.S. Shareholder’s portion of any interest income earned by the Trust generally will not be subject to U.S. federal income tax unless the Shares owned by such non-U.S. Shareholder are effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

D. Revenue Recognition

Interest on the primary deposit account, if any, accrues daily as earned and is received on a monthly basis.

E. Dividends

To the extent that the interest earned by the Trust exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trust will distribute, as a dividend (herein referred to as dividends or distributions), the excess interest earned in Japanese Yen effective on the first business day of the subsequent month. The Trustee will direct that the excess Japanese Yen be converted into USD at the prevailing market rate and the Trustee will distribute the USD as promptly as practicable to Shareholders on a pro-rata basis (in accordance with the number of Shares that they own).

Organization and Description of the Trust [Abstract]

Organization and Description of the Trust

1. Organization and Description of the Trust

The CurrencyShares ^® Japanese Yen Trust (the “Trust”) was formed under the laws of the State of New York on February 1, 2007 when Guggenheim Specialized Products, LLC d/b/a “Guggenheim Investments” (the “Sponsor”) deposited 10,000 Japanese Yen in the Trust’s primary deposit account held by JPMorgan Chase Bank, N.A., London Branch (the “Depository”). The Sponsor is a Delaware limited liability company whose sole member is Security Investors, LLC (also d/b/a “Guggenheim Investments”). The Sponsor is responsible for, among other things, overseeing the performance of The Bank of New York Mellon (the “Trustee”) and the Trust’s principal service providers, including the preparation of financial statements. The Trustee is responsible for the day-to-day administration of the Trust.

The investment objective of the Trust is for the Trust’s shares (the “Shares”) to reflect the price of the Japanese Yen plus accrued interest less the Trust’s expenses and liabilities. The Shares are intended to provide investors with a simple, cost-effective means of gaining investment benefits similar to those of holding Japanese Yen. The Trust’s assets primarily consist of Japanese Yen on demand deposit in two deposit accounts maintained by the Depository: a primary deposit account which may earn interest and a secondary deposit account which does not earn interest. The secondary deposit account is used to account for any interest that may be received and paid out on creations and redemptions of blocks of 50,000 Shares (“Baskets”). The secondary account is also used to account for interest earned, if any, on the primary deposit account, pay Trust expenses and distribute any excess interest to holders of Shares (“Shareholders”) on a monthly basis.

The accompanying audited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America.

9. Commitments and Contingencies

Under the Trust’s organizational documents, the Sponsor is indemnified against any liability or expense it incurs without negligence, bad faith or willful misconduct on its part. The Trust’s maximum exposure under this arrangement is unknown, as this would involve future claims that may be made against the Trust that have not yet occurred.

Concentration Risk

Oct. 31, 2012

Concentration Risk [Abstract]

Concentration Risk

8. Concentration Risk

All of the Trust’s assets are Japanese Yen, which creates a concentration risk associated with fluctuations in the price of the Japanese Yen. Accordingly, a decline in the Japanese Yen to USD exchange rate will have an adverse effect on the value of the Shares. Factors that may have the effect of causing a decline in the price of the Japanese Yen include national debt levels and trade deficits, domestic and foreign inflation rates, domestic and foreign interest rates, investment and trading activities of institutions and global or regional political, economic or financial events and situations. Substantial sales of Japanese Yen by the official sector (central banks, other governmental agencies and related institutions that buy, sell and hold Japanese Yen as part of their reserve assets) could adversely affect an investment in the Shares.

All of the Trust’s Japanese Yen are held by the Depository. Accordingly, a risk associated with the concentration of the Trust’s assets in accounts held by a single financial institution exists and increases the potential for loss by the Trust and the Trust’s beneficiaries in the event that the Depository becomes insolvent.

Significant Accounting Policies [Abstract]

Use of Estimates

A. Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of the assets, liabilities and disclosures of contingent liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period and the evaluation of subsequent events through the issuance date of the financial statements. Actual results could differ from those estimates.

Foreign Currency Translation

B. Foreign Currency Translation

The Trustee calculates the Trust’s net asset value (“NAV”) each business day, as described in Note 4. As of November 13, 2008, Japanese Yen deposits (cash) are translated for NAV calculation purposes at the Closing Spot Rate, which is the USD/Japanese Yen exchange rate as determined by The World Markets Company PLC, a State Street business, at 4:00 PM (London fixing) on each day that NYSE Arca is open for regular trading.

The functional currency of the Trust is the Japanese Yen in accordance with generally accepted accounting standards. For financial statement reporting purposes, the U.S. Dollar is the reporting currency. As a result, the financial records of the Trust are translated from Japanese Yen to USD. The Closing Spot Rate on the last day of the period is used for translation in the statements of financial condition. The average Closing Spot Rate for the period is used for translation in the statements of income and comprehensive income and the statements of cash flows. Any currency translation adjustment is included in comprehensive income.

Federal Income Taxes

C. Federal Income Taxes

The Trust is treated as a “grantor trust” for federal income tax purposes and, therefore, no provision for federal income taxes is required. Interest, gains and losses are passed through to the Shareholders.

Shareholders generally will be treated, for U.S. federal income tax purposes, as if they directly owned a pro-rata share of the assets held in the Trust. Shareholders also will be treated as if they directly received their respective pro-rata portion of the Trust’s income, if any, and as if they directly incurred their respective pro-rata portion of the Trust’s expenses. The acquisition of Shares by a U.S. Shareholder as part of a creation of a Basket will not be a taxable event to the Shareholder.

The Sponsor’s fee accrues daily and is payable monthly. For U.S. federal income tax purposes, an accrual-basis U.S. Shareholder generally will be required to take into account as an expense its allocable portion of the USD-equivalent of the amount of the Sponsor’s fee that is accrued on each day, with such USD-equivalent being determined by the currency exchange rate that is in effect on the respective day. To the extent that the currency exchange rate on the date of payment of the accrued amount of the Sponsor’s fee differs from the currency exchange rate in effect on the day of accrual, the U.S. Shareholder will recognize a currency gain or loss for U.S. federal income tax purposes.

The Trust does not expect to generate taxable income except for interest income (if any) and gain (if any) upon the sale of Japanese Yen. A non-U.S. Shareholder generally will not be subject to U.S. federal income tax with respect to gain recognized upon the sale or other disposition of Shares, or upon the sale of Japanese Yen by the Trust, unless: (1) the non-U.S. Shareholder is an individual and is present in the United States for 183 days or more during the taxable year of the sale or other disposition, and the gain is treated as being from United States sources; or (2) the gain is effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

A non-U.S. Shareholder’s portion of any interest income earned by the Trust generally will not be subject to U.S. federal income tax unless the Shares owned by such non-U.S. Shareholder are effectively connected with the conduct by the non-U.S. Shareholder of a trade or business in the United States.

Revenue Recognition

D. Revenue Recognition

Interest on the primary deposit account, if any, accrues daily as earned and is received on a monthly basis.

Dividends

E. Dividends

To the extent that the interest earned by the Trust exceeds the sum of the Sponsor’s fee for the prior month plus other Trust expenses, if any, the Trust will distribute, as a dividend (herein referred to as dividends or distributions), the excess interest earned in Japanese Yen effective on the first business day of the subsequent month. The Trustee will direct that the excess Japanese Yen be converted into USD at the prevailing market rate and the Trustee will distribute the USD as promptly as practicable to Shareholders on a pro-rata basis (in accordance with the number of Shares that they own).

Redeemable Capital Shares

Redeemable Capital Shares [Abstract]

Redeemable Capital Shares

4. Redeemable Capital Shares

Shares are classified as “redeemable” for financial statement purposes, since they are subject to redemption. Shares are issued and redeemed continuously in Baskets in exchange for Japanese Yen. Individual investors cannot purchase or redeem Shares in direct transactions with the Trust. Only Authorized Participants (as defined below) may place orders to create and redeem Baskets. An Authorized Participant is a Depository Trust Company (“DTC”) participant that is a registered broker-dealer or other institution eligible to settle securities transactions through the book-entry facilities of DTC and which has entered into a contractual arrangement with the Trust and the Sponsor governing, among other matters, the creation and redemption process. Authorized Participants may redeem their Shares at any time in Baskets.

Due to expected continuing creations and redemptions of Baskets and the three-day period for settlement of each creation or redemption, the Trust reflects Shares created as a receivable. Shares redeemed are reflected as a liability on the trade date. Outstanding Shares are reflected at a redemption value, which is the NAV per Share at the period end date. Adjustments to redeemable capital Shares at redemption value are recorded against retained earnings or, in the absence of retained earnings, by charges against the cumulative translation adjustment.

Activity in redeemable capital Shares is as follows:

	Year ended October 31, 2012						Year ended October 31, 2011						Year ended October 31, 2010
	Shares			U.S. Dollar Amount			Shares			U.S. Dollar Amount			Shares			U.S. Dollar Amount

The Trustee calculates the Trust’s NAV each business day. To calculate the NAV, the Trustee subtracts the Sponsor’s accrued fee through the previous day from the Japanese Yen held by the Trust (including all unpaid interest accrued, if any, through the preceding day) and calculates the value of the Japanese Yen in USD based upon the Closing Spot Rate. If, on a particular evaluation day, the Closing Spot Rate has not been determined and announced by 6:00 PM (London time), then the most recent Closing Spot Rate will be used to determine the NAV of the Trust unless the Trustee, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for the valuation. If the Trustee and the Sponsor determine that the most recent Closing Spot Rate is not an appropriate basis for valuation of the Trust’s Japanese Yen, they will determine an alternative basis for the valuation. The Trustee also determines the NAV per Share, which equals the NAV of the Trust divided by the number of outstanding Shares. Shares deliverable under a purchase order are considered outstanding for purposes of determining NAV per Share; Shares deliverable under a redemption order are not considered outstanding for this purpose.
