Example
Worked example — Numbers in kanji
Type the numbers, one per line. Commas and a yen sign are ignored. Use the following inputs and settings. Keep the other settings at the page defaults.
| Item | Value |
|---|---|
| Input | 12345 |
| Output 1 | 一万二千三百四十五 |
12345 is grouped as 1×10000 + 2×1000 + 3×100 + 4×10 + 5.
How it works
- Type the numbers, one per line. Commas and a yen sign are ignored.
- Choose how it is written: the way it is read, or digit by digit as an address or a serial number is.
- Turn on the formal forms for a contract, a receipt or a registration.
- Copy the result.
Frequently asked questions
- What are the formal forms for?
- To stop a figure being altered. 一 becomes 壱 and 二 becomes 弐 precisely because a pen stroke turns one into the other; 十 becomes 拾 for the same reason. They are required on some legal and financial documents and are usual on handwritten receipts.
- Which characters does Japanese law actually require?
- Only 壱, 弐, 参 and 拾 (and 萬 for 万). 四 and 五 keep their ordinary forms — unlike the fuller Chinese set, which also has 肆 and 伍. This follows the Japanese practice.
- What is 金〇〇円也?
- The way an amount is written on a receipt: 金 before it, 円也 after. The 也 closes the figure so nothing can be added to the end.
- When would I want it digit by digit?
- For an address written vertically, a telephone number, or a year on a formal document — 二〇二六年 rather than 二千二十六年.
- Is anything sent anywhere?
- No. It is converted in your browser.
