MizuruGo from zero to reading real Japanese.
News, classic stories, the sign on the street corner. Mizuru pairs a 9,894-word JLPT dictionary and all 828 grammar points with an FSRS memory engine that reviews only what you're about to forget — so every minute moves you toward reading, not re-drilling.
Real Japanese — at your exact level, from the very first day.
Mizuru puts authentic Japanese in front of you from day one — real news and classic stories, tuned to exactly where you are, so every session is the real thing.
- The same news story, five ways. Every article is rewritten across N5→N1 with furigana, audio narration, and comprehension questions.
- 100+ Aozora Bunko classics with furigana, a parallel modern-Japanese translation, and karaoke audio you can slow to 0.5×.
- Scan & Read. Point your camera at a menu or a sign — get furigana, a vocab breakdown, and a translation in your language.
- Know before you dive in. Each article shows its key vocab, grammar, and your mastery % — so you prep exactly what you need.
Grammar you finally get — not grammar you cram.
納得 (nattoku) means “now it makes sense.” Instead of a dry rule to memorize, every point gets a guided 納得 lesson that builds the pattern up from real examples until it just clicks — then a quick test locks it in.
The real in-app lesson for A。でも、〜B。 — swipe through all six steps, then a quick test locks it in.
- A step-by-step walkthrough for each point — you see how the pattern works, not just what it is.
- A two-voice example conversation that shows the grammar in the wild, with tap-to-hear audio.
- A quick check & test so you know it stuck — then the point enters your review deck.
- All 828 JLPT points, N5–N1 — look up exactly the grammar you hit while reading.
Say what you actually mean — in real Japanese.
Stuck mid-conversation? Type what you want to say — in Japanese or in your own language — and Mizuru shows you how a native would put it, with furigana and a note on why. Speak like yourself, not like a phrasebook.
- Type it your way. “How do I say I’ll be about five minutes late?” → 5分ほど遅れます — natural, with furigana and the nuance explained.
- Replies you can always follow. The AI reads your review deck and answers only with words you’ve mastered — plus at most one new one.
- Gentle corrections + a weak-spot tutor that targets your highest-lapse patterns, like 〜てしまう vs 〜てしまった.
- Save any word from a conversation straight into your deck — every reply is a lesson.
Six tools for the moments textbooks can’t reach.
Real situations don’t wait until chapter 12. Wherever Japanese meets you — a chat, a counter, a menu — there’s a tool for it, and each one teaches while it helps.
Chat through 14 everyday scenes — replies stay inside words you know.

Mizuru runs on FSRS, the modern spaced-repetition algorithm. Words you find hard come back fast; words you've mastered drift into long intervals and stop stealing your attention.
- Never re-drill what you already know. Five review modes — flashcards, speed, typing, matching, and audio-block rebuild.
- Words enter your deck as you learn them — from lessons, reading, conversations, or a scan. Everything you meet, you can keep.
- Local-first, sync optional. Learn offline on your device; sign in to carry your progress across phones.
The core isn't a trial. It's the whole ladder, N5 to N1.
No paywall on the fundamentals. The AI extras have a generous free daily quota; reviewing is never capped.
