Shiritai — Furigana Reader for Japanese av Alina

Read real Japanese anywhere on the web. Shiritai adds furigana above every kanji, looks up any word on click, highlights words by JLPT level, and explains the text you select — with translation, grammar, vocab, kanji, and JLPT notes.

Tired of copy-pasting Japanese into a dictionary every few words? Shiritai turns the entire web into reading practice. Whether you're scrolling X/Twitter, reading a blog, watching YouTube, browsing news, or reading manga and novels online, furigana appears instantly above the kanji so you can keep reading without losing your place — and a single click on any word opens an instant dictionary popup.

What it does

• Instant furigana — Automatically adds hiragana readings above kanji on any page, so you can read real Japanese instead of studying isolated sentences. Works offline.

• Click-to-lookup dictionary — Click any word for a popup with its dictionary form, reading, part of speech, and English meanings from the full JMdict dictionary — plus pronunciation. The entire dictionary is built in, so lookups never need the internet.

• JLPT level highlights — Color words by JLPT level (N5–N1) to see at a glance what's within reach. Set your "known" level and furigana hides for words you should already know, so you're not spoon-fed readings.

• Adjustable reading size — Tune the furigana text size to whatever's comfortable to read.

• One-click toggle — Turn readings on or off anytime from the popup, per page. Keep pages clean when you don't need help.

• Explain any selection — Select Japanese text, right-click, and open a full study card in Shiritai: natural + literal translation, grammar breakdown, vocabulary, kanji meanings and readings, casual/social-media nuance, and an estimated JLPT level.

Why install it

• Read real Japanese sooner. Authentic posts and articles are the fastest way to improve — and now you can actually read them.

• Stay in flow. No more jumping between tabs, dictionaries, and translator apps. Readings, word lookups, and level hints are right where the text is.

• Private by design. Furigana and the dictionary run entirely in your browser. Your page content doesn't leave your device just to add readings or look up words.

• Built for learners. Explanations are tuned for N5–N2 learners, with casual and social-media nuance you won't find in textbooks.

Perfect for Japanese learners who want to learn from the real internet — the posts, comments, and articles you actually want to read.
