Residence card, My Number, a Japanese bank account, name matching, visa validity, and troubleshooting rejections.
A foreign resident generally needs a residence card, My Number, a Japanese bank account in the same name, and valid tax-residency declarations; applications are online or by post depending on the broker, and most rejections come from name mismatches or short document validity.
The core requirements are a Japan-resident address; identity evidence such as a My Number Card, residence card, driver’s licence, or passport in an accepted combination; My Number evidence; and a linked Japanese bank account in your own name for funding and withdrawals. You will also make Japanese and foreign tax-residency declarations, and provide employment, insider, and source-of-funds information.
A My Number Card usually enables the fastest identity process; a residence card without a My Number Card is often accepted with additional My Number and address documents. US citizens and green-card holders complete a FATCA declaration and may face product restrictions.
How you apply varies by broker. Some firms permit fully online opening with a residence card; others require postal processing for foreign nationals, which takes longer. SBI, Rakuten, Monex, and Matsui publish procedures accepting residence-card documentation, though the exact online/postal path differs. Check the current process for your nationality before choosing.
Visa and residence-card validity matter even though the tax rule is residence-based: a short remaining validity can delay or prevent opening, because the broker assesses how long you can be served. Ensure your card has reasonable time left before applying.
Common rejection causes are a name mismatch across documents, short document validity, an unsupported nationality or tax residence, a duplicate NISA at another institution, or a failed identity verification. Politically exposed status or a sanctioned-country connection can trigger enhanced review or rejection, and these policies are rarely published in full.
Before reapplying, fix the specific cause: align your name across the residence card, bank record, and application; renew a soon-to-expire card; resolve any duplicate NISA; and confirm the broker accepts your nationality and residence status. If a duplicate NISA is the issue, you may need transfer or abolition documents from the other institution first.

Generally yes, if you are a tax resident of Japan (with a My Number) and at least 18. NISA is tied to residency, not citizenship, so most foreign residents qualify — with two big cautions: US citizens and green-card holders face US tax complications with Japanese funds, and NISA generally cannot continue after you leave Japan.
