Organization	Note 2 - Organization The Invesco CurrencyShares^®Japanese Yen Trust (the “Trust”) was formed under the laws of the State of New York on February 1, 2007 when 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 Invesco Capital Management. The Trust has an unlimited number of shares authorized for issuance. The investment objective of the Trust is for the Trust’s shares (the “Shares”) to reflect the price in U.S. Dollars (“USD”) of the Japanese Yen plus accrued interest, if any, 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. This Annual Report (the “Annual Report”) covers the years ended December 31, 2022 and 2021.
