Yes. Japanese income and financial accounts should also be reviewed for U.S. tax purposes. Whether they are taxable or reportable depends on your U.S. tax residency, the income involved, and the nature and value of the accounts and assets.
Must I Report Japanese Income?
U.S. tax residents are generally subject to U.S. tax on worldwide income, including Japanese salary, interest, dividends, investment gains, and rental income.
Receiving income in Japan or paying Japanese tax on it does not, by itself, remove the U.S. reporting requirement.

What About Taxes Paid in Japan?
Foreign tax credits and other applicable provisions may help address double taxation. However, Japanese taxes are not necessarily creditable in full. The type of tax, income category, and applicable limitations must be reviewed.
Reference: IRS — Publication 514
Must I Report Japanese Financial Accounts?
Japanese bank and investment accounts may require foreign financial account or asset reporting, including FBAR and Form 8938.
Generally, a U.S. person must file an FBAR if the aggregate value of foreign financial accounts in which they have a financial interest or signature authority exceeds $10,000 at any time during the calendar year. This threshold applies to the combined accounts, not each account separately.
Form 8938 reports certain foreign financial assets with the income tax return. Its thresholds vary by filing status and residence.
These are separate requirements; filing one does not replace the other.

What If an Account Generates No Income?
Income taxation and account reporting are separate matters. An account may be reportable even without income. Maximum values during the year, rather than only year-end balances, may need to be reviewed.
Information to Gather
- Types and amounts of Japanese income
- Japanese taxes withheld or paid
- Japanese bank and investment accounts
- Account ownership, joint ownership, and signature authority
- Maximum annual and year-end balances
- Arrival and departure dates and prior filing history
We review income reporting and foreign account and asset reporting separately to identify the necessary steps. Please provide only an overview in your initial inquiry. We will explain how to share confidential documents separately.
This answer primarily addresses U.S. federal taxation and foreign account and asset reporting. Different rules may apply to nonresidents and arrival or departure years. State taxes require separate review.
