Furigana Reader for Any Japanese Page

Furigana — the small kana above kanji — keeps you reading when pronunciation is all that's slowing you down. よむ adds furigana to any Japanese web page for free, with no account, and you control exactly how much shows.

Try it: the text below has furigana rendered by よむ. Install the userscript and the same thing happens on real pages, manga, and subtitles.

You choose how much help

Furigana and word coloring are separate controls, so you can dial reading support to your exact level:

• All words — furigana above everything. Good for absolute beginners and read-alouds.
• Hard kanji only — readings only for less common kanji, so easy words stay clean.
• Hide for known words — once you've learned a word (via Jiten, JPDB, or Anki), its furigana disappears, nudging recall.
• Off — rely on tap-to-look-up instead.

Furigana comes from the same parser that powers lookup, so every word stays tappable: tap for the full meaning, kanji breakdown, pitch, audio, and mining.

Works everywhere you read

The same furigana settings apply across every reading surface: web pages, manga read through OCR, and video subtitles on YouTube and your own video files.

Set it up

1. Install the free よむ userscript (see the setup guide).
2. Open a Japanese page.
3. Open よむ settings and pick a furigana mode — all words, hard kanji only, or hide-for-known.

Questions

Does furigana work on manga and subtitles too? Yes — manga read through OCR and video subtitles become the same tappable text, so furigana settings apply there as well.

Will it show furigana only for hard words? Yes — pick "hard kanji only," or hide furigana for words you've already learned in Jiten, JPDB, or Anki.
