How to fill in bank details to send money to Japan?

When filling in the account number and bank branch code for a Japan bank transfer, please note that:

• Your account is a savings/general account (Futsuu).
• Your account number is usually 5-8 digits, shown on your savings book/passbook.
• • If your passbook shows a set of numbers (most likely 5 digits, used for local transfers in Japan) before your account number, you don't need to include it when sending with Topremit.
• Your bank branch code is 3 digits, also shown on your savings book/passbook.

Sending Money to Yucho (or Yuutyo) - Japan Post Office?

Japan Post Office accounts use a different format from other Japanese banks: a 5-digit 記号 (symbol) and 8-digit 番号 (number), instead of a standard 3-digit bank branch code and 7-digit account number. Because of this, you'll need to convert these details before entering them on Topremit.

Where to find your 記号 (symbol) ・ 番号 (number)

• Passbook/bankbook: Your book may already show a converted branch code and account number. If so, you can use them directly, no conversion needed.
• Card: Your card might only show the 記号 (symbol) ・ 番号 (number) format, which must be converted before use.

How to convert 記号 (symbol) ・ 番号 (number) to the standard bank branch code and account number format

You can use Japan Post's official conversion tool by following these steps:

• Visit the Japan Post Bank Account Conversion Tool
• Enter your 5-digit 記号 (symbol) and 8-digit 番号 (number).

• Confirm the 5-digit 記号 (symbol) and 8-digit 番号 (number) you entered. Make sure they're correct so the conversion result is valid.

• Conversion complete! You can enter the resulting bank branch code and account number on Topremit.

If you'd like to convert manually, follow the guide below:

• If your 記号 (symbol) starts with 1:
• • Bank branch code (3 digits): take the 2nd and 3rd digits of your 記号 (symbol), then add "8".
  • Account number (7 digits): remove the last digit ("1") of your 番号 (number). If the result is fewer than 7 digits, add "0"s in front until it's 7 digits.

• If your 記号 (symbol) starts with 0:
• • Bank branch code (3 digits): take the 2nd and 3rd digits of your 記号 (symbol), then add "9".
  • Account number (7 digits): use all digits of your 番号 (number) as-is. If the result is fewer than 7 digits, add "0"s in front until it's 7 digits.
