KanjiPadKanji for numbers
Thirteen characters cover nearly every number in Japanese: 一 through 十, then 百 (hundred), 千 (thousand) and 万 (ten thousand). They are the first kanji most learners write, and among the simplest — 一 is a single stroke. Tap any of them for animated stroke order, readings and example words.
Number kanji 1 to 10
Hundred, thousand, ten thousand
Above ten, Japanese groups digits in fours rather than threes. 万 (ten thousand) is a unit of its own, so 100,000 is 十万 — ten 万 — and a million is 百万, a hundred 万.
How counting works
From 11 to 99 the numbers are simple arithmetic written out. 十一 is ten-one (11), 二十 is two-ten (20), 二十一 is 21, 九十九 is 99. 百 and 千 behave the same way: 三百 is 300 and 千五百 is 1500. Only a few readings shift — 四 is usually yon, 七 is nana, and 九 is kyū when you are counting aloud.
Dates and counters
Dates reuse these kanji with irregular readings worth learning as words: 一日 (tsuitachi) is the first of the month, 二十日 (hatsuka) the twentieth. Counting objects works the same way — the kanji stays, the reading follows the counter.
Write every number kanji stroke by stroke, and keep them with spaced repetition, in the app.
