Kanji → Hiragana converter — kuromoji morphological reading
Convert Japanese text to hiragana using kuromoji morphological analysis. Choose between fully hiragana output, or a furigana mode that keeps kanji and adds hiragana ruby above. The dictionary downloads once and is then offline. Runs entirely in your browser.
How to use
Paste Japanese text, pick a mode (full hiragana or furigana ruby), and click Convert. kuromoji performs morphological analysis and infers a reading for each kanji. The dictionary (~12 MB) downloads once and is then offline. One-click copy is available. The Sample button loads example text.
FAQ
- Is text uploaded?
- No. kuromoji and its dictionary run inside your browser; input and output never leave the device.
- Why is the first run slow?
- The ~12 MB morphological dictionary is downloaded and cached. Subsequent runs are instant.
- Are proper nouns / names always correct?
- Not always. Words not in kuromoji's IPA dictionary may be misread. Common place names and famous people work; unusual personal names need review.
- How is furigana rendered?
- As HTML ruby tags, the standard small hiragana above each kanji. The HTML can be copied directly.
