Once you know 1–10, Japanese numbers up to 100 follow a compact pattern. A multiple of ten combines the digit with 十 (jū), and the final digit follows it.
The tens
| Number | Kanji | Hiragana | Romaji |
|---|---|---|---|
| 10 | 十 | じゅう | jū |
| 20 | 二十 | にじゅう | nijū |
| 30 | 三十 | さんじゅう | sanjū |
| 40 | 四十 | よんじゅう | yonjū |
| 50 | 五十 | ごじゅう | gojū |
| 60 | 六十 | ろくじゅう | rokujū |
| 70 | 七十 | ななじゅう | nanajū |
| 80 | 八十 | はちじゅう | hachijū |
| 90 | 九十 | きゅうじゅう | kyūjū |
| 100 | 百 | ひゃく | hyaku |
Build the numbers between tens
Put the ones digit after the tens:
- 11: 十一 — じゅういち — jūichi
- 21: 二十一 — にじゅういち — nijūichi
- 35: 三十五 — さんじゅうご — sanjūgo
- 48: 四十八 — よんじゅうはち — yonjūhachi
- 99: 九十九 — きゅうじゅうきゅう — kyūjūkyū
Unlike English, there is no extra word like “and” between the parts.
How to say 67 in Japanese
Break 67 into 60 + 7. Sixty is 六十 (rokujū) and seven is 七 (nana), so 67 is:
六十七 — ろくじゅうなな — rokujū nana
Our converter displays the plain-keyboard Romaji rokujuu nana. The space is a reading aid; Japanese normally writes the Kanji together.
Kanji numerals and Arabic digits
Modern Japanese uses both. Prices, measurements, addresses, and technical text often use Arabic digits, while Kanji appear in prose, formal expressions, and established compounds. Context and house style determine the best choice.
The system continues above 100, but a few sound changes occur: 300 is さんびゃく (sanbyaku), 600 is ろっぴゃく (roppyaku), and 800 is はっぴゃく (happyaku).
Practice with a converter
Use the Japanese Number Converter and enter random values from 1 to 100. Predict the output first, then compare all four forms: Kanji, Hiragana, Katakana, and Romaji.
After the pattern feels automatic, practice the same numbers with counters. A bare number and a counted noun may not have exactly the same pronunciation.
