Tips for Navigating Japanese Broker Websites

  • Use Google Translate or DeepL browser extensions to translate pages in real time
  • Your name should be entered in katakana (カタカナ) for the Japanese name field — use an online converter if needed
  • Your address must match exactly what is on your residence card
  • If the eKYC step fails, try in a well-lit area and make sure your residence card is flat and fully visible
  • If you get stuck, Rakuten and SBI both have customer support chat — use Google Translate to communicate

Common Issues and How to Fix Them

My Number not accepted
Make sure you are entering the 12-digit My Number correctly. If you only have the paper notification letter (通知カード), some brokers may require additional documents such as your residence card to confirm your address.

Identity verification keeps failing
eKYC systems can struggle with residence cards that have worn edges or poor lighting. Try using your smartphone’s rear camera in natural light, and make sure the card lies completely flat.

No Japanese bank account yet
You need a Japanese bank account before you can fund your NISA. Japan Post Bank (ゆうちょ銀行) and Sony Bank are generally the most accessible options for new residents. SBI Shinsei Bank also offers an English-language application process.

Application rejected without explanation
This occasionally happens if your address registration at the municipal office is not yet complete. Make sure your residence card address is up to date before applying.
