Generally, no. NISA is a Japanese tax exemption system. Its Japanese tax benefits do not automatically apply in the United States.
U.S. citizens and tax residents must review dividends, distributions, and gains within NISA accounts under U.S. tax rules.

1. Review Each Investment
A NISA account may hold stocks, investment funds, or ETFs. U.S. treatment depends on the investments and their legal structure, not just the account’s label.
Dividends, distributions, and sales may require U.S. reporting even when exempt in Japan.
2. Investment Funds May Have Special Treatment
Non-U.S. investment funds and ETFs may qualify as passive foreign investment companies (PFICs).
PFIC holdings may require Form 8621 and special tax calculations or elections. Depending on the circumstances and elections, reporting or income calculations may be required even without a sale.
Review the specific investments rather than assuming that all products receive the same treatment.
Reference: IRS — Instructions for Form 8621
3. What About Foreign Tax Credits?
Foreign tax credits generally require qualifying foreign taxes paid or accrued. If NISA exempts income from Japanese income tax, there is no Japanese tax on that exempt income to credit.
Taxes imposed by another country—for example, on foreign-stock dividends—require separate review.
Reference: IRS — Publication 514
4. Review Account and Asset Reporting
NISA accounts may also require FBAR or Form 8938 reporting when applicable requirements are met.
Income taxation and financial reporting are separate. Japanese tax exemption or the absence of sales does not automatically eliminate reporting.
