CurrencyShares^® Japanese Yen Trust

Notes to Financial Statements

(Unaudited)

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 unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions for Form 10-Q. In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s financial statements included in the Form 10-K as filed on January 14, 2014.

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 WM Company, at 4:00 PM (London time/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 comprehensive income and the statements of cash flows. Any currency translation adjustment is included in comprehensive income.

6

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).

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 April 30, 2014 was an annual nominal rate of 0.00%. For the six months ended April 30, 2014, there were Japanese Yen principal deposits of 16,603,554,726, Japanese Yen principal redemptions of 20,012,261,862 and Japanese Yen withdrawals (to pay expenses) of 35,201,275 resulting in an ending Japanese Yen principal balance of 10,734,705,896. This equates to 105,087,674 USD. For the year ended October 31, 2013, there were Japanese Yen principal deposits of 68,580,969,566, Japanese Yen principal redemptions of 64,654,426,112 and Japanese Yen withdrawals (to pay expenses) of 56,370,633 resulting in an ending Japanese Yen principal balance of 14,178,614,307. This equates to 144,517,524 USD.

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.

7

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:

	Six months ended April 30, 2014 (Unaudited)						Year ended October 31, 2013
	Shares			U.S. Dollar Amount			Shares			U.S. Dollar Amount
Opening balance		1,450,000		$	144,463,850			1,050,000		$	128,920,251
Shares issued		1,700,000			162,107,203			7,000,000			726,650,352
Shares redeemed		(2,050,000	)		(195,387,786	)		(6,600,000	)		(685,046,621	)
Adjustment to period Shares due to currency movement and other		—			(6,132,963	)		—			(26,060,132	)
Ending balance		1,100,000		$	105,050,304			1,450,000		$	144,463,850

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.

8

5. 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.

6. 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.

7. 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.

8. 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.

Readers are urged to review the “Risk Factors” section contained in the Trust’s most recent annual report on Form 10-K 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.

Trust Overview

The CurrencyShares^® Japanese Yen Trust (the “Trust”) is a grantor trust that was formed on February 1, 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 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 is a passive investment vehicle. The Trust does not have any officers, directors or employees. The investment objective of the Trust is for the Shares to reflect the price of Japanese Yen plus accrued interest, less the expenses of the Trust’s operations. The Trust does not engage in any activities designed to obtain profit from, or ameliorate losses caused by, changes in the price of Japanese Yen.

Definition of 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, if any, 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. The NAV is expressed in USD based on the Japanese Yen/USD exchange rate as determined by The WM Company, at 4:00 PM (London time/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 are posted on the Trust’s website, www.currencyshares.com.

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 Closing Spot Rate.

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 Arca and (3) the Closing Spot Rate, 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 that may earn interest and a secondary deposit account that 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 April 30, 2014 was an annual nominal rate of 0.00%. The following chart provides the daily rate paid by the Depository since April 30, 2009:

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 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, 2013, the number of Japanese Yen owned by the Trust was 14,178,614,307, resulting in a redeemable capital share value of $144,463,850. During the six months ended April 30, 2014, an additional 1,700,000 Shares were created in exchange for 16,603,554,726 Japanese Yen and 2,050,000 Shares were redeemed in exchange for 20,012,261,862 Japanese Yen. In addition, 35,201,275 Japanese Yen were withdrawn to pay the portion of sponsor fee that exceeded the interest earned. As of April 30, 2014, the number of Japanese Yen owned by the Trust was 10,734,705,896, resulting in a redeemable capital Share value of $105,050,304.

A decrease in the Trust’s redeemable capital Share value from $144,463,850 at October 31, 2013 to $105,050,304 at April 30, 2014, was primarily the result of a decrease in the number of Shares outstanding from 1,450,000 at October 31, 2013 to 1,100,000 at April 30, 2014 coupled with a decrease in the Closing Spot Rate from 0.010193 at October 31, 2013 to 0.009789 at April 30, 2014.

No interest income was earned during the three months ended April 30, 2013, the three months ended April 30, 2014, the six months ended April 30, 2013 and the six months ended April 30, 2014 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 $147,006 for the three months ended April 30, 2013 to $165,658 for the three months ended April 30, 2014, and increased from $322,673 for the six months ended April 30, 2013 to $329,548 for the six months ended April 30, 2014. The only expense of the Trust during the three months and six months ended April 30, 2014 was the Sponsor’s fee.

The Trust’s net loss for the three months ended April 30, 2014 was $165,658, due to the Sponsor’s fee of $165,658 exceeding the Trust’s interest income of $0. The Trust’s net loss for the six months ended April 30, 2014 was $329,548, due to the Sponsor’s fee of $329,548 exceeding the Trust’s interest income of $0.

Cash dividends were not paid by the Trust during the three months ended April 30, 2013, the three months ended April 30, 2014, the six months ended April 30, 2013 and the six months ended April 30, 2014 as the Trust’s interest income did not exceed the Trust’s expenses during those periods.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Except as described above with respect to the USD/Japanese Yen exchange rate and the nominal annual interest rate paid by the Depository on Japanese Yen held by the Trust, the Trust is not subject to market risk. The Trust does not hold securities and does not invest in derivative instruments.

Item 4. Controls and Procedures

The Trust maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) designed to ensure that material information relating to the Trust is recorded, processed and disclosed on a timely basis. The Trust’s disclosure controls and procedures are designed by or under the supervision of the Sponsor’s chief executive officer and chief financial officer, who exercise oversight over the Trust as the Trust has no officers. The chief executive officer and chief financial officer of the Sponsor have evaluated the effectiveness of the Trust’s disclosure controls and procedures as of April 30, 2014. 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 report.

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.

Japanese Yen Deposits

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 April 30, 2014 was an annual nominal rate of 0.00%. For the six months ended April 30, 2014, there were Japanese Yen principal deposits of 16,603,554,726, Japanese Yen principal redemptions of 20,012,261,862 and Japanese Yen withdrawals (to pay expenses) of 35,201,275 resulting in an ending Japanese Yen principal balance of 10,734,705,896. This equates to 105,087,674 USD. For the year ended October 31, 2013, there were Japanese Yen principal deposits of 68,580,969,566, Japanese Yen principal redemptions of 64,654,426,112 and Japanese Yen withdrawals (to pay expenses) of 56,370,633 resulting in an ending Japanese Yen principal balance of 14,178,614,307. This equates to 144,517,524 USD.

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.

Apr. 30, 2014

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 WM Company, at 4:00 PM (London time/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 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

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 unaudited financial statements were prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions for Form 10-Q. In the opinion of management, all material adjustments, consisting only of normal recurring adjustments, considered necessary for a fair statement of the interim period financial statements have been made. Interim period results are not necessarily indicative of results for a full-year period. These financial statements and the notes thereto should be read in conjunction with the Trust’s financial statements included in the Form 10-K as filed on January 14, 2014.

Sponsor's Fee

5. 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.

Significant Accounting Policies (Policies)

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 WM Company, at 4:00 PM (London time/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 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).

Concentration Risk

Risks And Uncertainties [Abstract]

Concentration Risk

7. 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.

Commitments and Contingencies

8. 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.

Redeemable Capital Shares

Equity [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:

	Six months ended April 30, 2014 (Unaudited)						Year ended October 31, 2013
	Shares			U.S. Dollar Amount			Shares			U.S. Dollar Amount
Opening balance		1,450,000		$	144,463,850			1,050,000		$	128,920,251
Shares issued		1,700,000			162,107,203			7,000,000			726,650,352
Shares redeemed		(2,050,000	)		(195,387,786	)		(6,600,000	)		(685,046,621	)
Adjustment to period Shares due to currency movement and other		—			(6,132,963	)		—			(26,060,132	)
Ending balance		1,100,000		$	105,050,304			1,450,000		$	144,463,850

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.
