The hiragana that trails after kanji isn’t decoration — it tells you how to read the word, how to conjugate it, and where it ends. A beginner’s guide to okurigana.
Open any Japanese sentence and you’ll notice that kanji don’t sit alone. They almost always have a small tail of hiragana attached — 食べる, 新しい, 読んだ. That tail is called okurigana (おくりがな), and it’s doing real work: it tells you how the kanji is read, what grammatical form the word is in, and where the word stops.
This guide walks through the rules so the tail stops looking like decoration, and starts doing what it’s actually there to do.
The kanji in a word is the stem — the part that carries the core meaning and that never changes shape. The hiragana after it is the ending — the part that does change shape when you conjugate. That trailing hiragana is okurigana.
Three quick examples using the verb “to eat”:
The kanji 食 stays put. Everything that changes — -ru, -nai, -ta — is written in hiragana. Without okurigana, Japanese couldn’t conjugate verbs or adjectives on the page at all; the kanji would just be a frozen symbol with no way to show tense, politeness, or negation.
Chinese characters were originally designed for Chinese, which doesn’t conjugate. Japanese does — verbs and adjectives bend in all directions. When kanji were imported, Japanese had to invent a way to attach its own grammatical endings to characters that were never meant to carry them. Okurigana is that solution.
Beyond conjugation, okurigana also does two subtler jobs:
Almost every native Japanese verb is written as kanji stem + hiragana ending. The ending is where conjugation happens.
| Dictionary form | Reading | Meaning |
|---|---|---|
| 見る | mi-ru | to see |
| 書く | ka-ku | to write |
| 話す | hana-su | to speak |
| 飲む | no-mu | to drink |
| 食べる | ta-beru | to eat |
| 出る | de-ru | to exit, leave |
The first big rule falls out of these examples: the last syllable of the dictionary form is always in hiragana. Whether that’s -ru, -ku, -su, -tsu, -mu, -nu, -bu, -gu, or the long -eru/-iru endings of ichidan verbs, the final syllable rides in okurigana so that it can change when needed.
Watch it bend:
| Form | Japanese | Reading |
|---|---|---|
| Dictionary | 書く | kaku — writes / will write |
| Masu-form | 書きます | kakimasu — writes (polite) |
| Past | 書いた | kaita — wrote |
| Negative | 書かない | kakanai — doesn’t write |
| Te-form | 書いて | kaite — writing / and then write |
The kanji 書 never moves. The okurigana morphs into every form the grammar demands. You can parse half a Japanese sentence just by reading the tails.
Japanese has two kinds of adjectives, and okurigana looks very different on each.
い-adjectives end in a hiragana い that is part of the word itself and that changes shape with the grammar:
| Japanese | Reading | Meaning |
|---|---|---|
| 新しい | atarashi-i | new |
| 古い | furu-i | old |
| 大きい | ooki-i | big |
| 小さい | chiisa-i | small |
| 高い | taka-i | tall / expensive |
When you negate an い-adjective, that final い becomes くない: 新しい → 新しくない (not new). Past tense: 新しかった (was new). Again, the kanji stays locked; the hiragana does all the moving.
な-adjectives are different — they’re nouns that happen to describe. They don’t take okurigana at all in their base form: しずか (quiet), べんり (convenient), ゆうめい (famous). The な only appears when the word attaches to a noun (しずかな へや, “a quiet room”), and even then it lives between the adjective and the noun, not as a suffix glued to the stem.
This is the subtler job okurigana does, and it’s the one that makes reading Japanese much easier once you notice it.
Many kanji appear in several different verbs, and the okurigana is what tells you which verb you’re looking at. Take the kanji 見 (“see”):
Same kanji, three different verbs, three different meanings — and the only thing distinguishing them on the page is the hiragana tail. See 〜る after 見 → it’s plain miru, “to see.” See 〜える → it’s mieru, something is visible. See 〜せる → it’s miseru, you’re showing it. The tail is your cue.
The same pattern shows up with 出 (“exit, go out”):
Two verbs built from the same kanji, meaning two different things, told apart only by the hiragana suffix. Once you start looking for the tail, you stop guessing and start reading.
If you remember one thing, make it this: the okurigana is only the part of the reading that needs to change when the word conjugates — everything that stays fixed is baked silently into the kanji.
That means a kanji can hide more of the reading than you’d expect. “To speak” is hana-su, but written 話す: only す is in the tail, while ha-na- is tucked inside 話. “To rest” is yasu-mu, written 休む: only む is the tail, and ya-su- is hidden inside 休. This is why learners sometimes mis-spell words — they put too much (or too little) of the reading into okurigana.
There are formal rules published by the Japanese government (the okurigana no tsukekata guidelines from 1973), but you don’t need to memorize them. For 95% of words, the pattern is: the final changing syllable, plus anything that must change with it. Learn each word with its correct split, and it becomes muscle memory after a few dozen examples.
Rather than studying okurigana as a separate topic, bake it in as you learn each word:
Okurigana is one of those features of Japanese that looks like a complication at first and turns into a quiet helper once you’ve learned to see it. Every tail you read is the language reminding you how the word is pronounced, what form it’s in, and where it ends — three jobs in a single stroke of kana.
A beginner-friendly walkthrough on okurigana worth bookmarking. If you’re already practicing kanji, this pairs perfectly with where you are — once you can read the tail first, every new verb and adjective starts to parse itself.
