Convert amounts or numbers into Japanese kanji numerals (一, 二, 三…) and daiji — the formal, anti-tamper figures (壱, 弐, 参…) used on gift envelopes, receipts, and contracts in Japan. It also builds the formal amount form like 金壱萬円也. Everything is computed locally; the number you type is never stored or uploaded (only your kanji-style preference is saved on this device).
How to use
- Type a number (commas and full-width digits are fine).
- Pick the style: Kanji or Daiji (formal).
- Copy the kanji numeral and the 金…円也 amount form.
FAQ
What is daiji?

Is the number I enter stored?
No. Conversion runs entirely in your browser; the number is never stored or uploaded. Only your kanji-style preference is saved on this device.
Can it build the 金…円也 amount form?
Yes. The amount field generates the formal form such as 金壱萬円也, ready to copy onto an envelope or receipt.
How large a number is supported?
Up to 16 digits. Decimals are not supported (it is for whole-number amounts and IDs).
