Learn Japanese from Zero to fluent, one habit at a time
Structured N5 lessons, spaced-repetition review, an AI tutor that actually talks back, and an immersion mode that grows with you — ZeroNihongo is the Japanese app built for people who want to stick with it.
Everything you need, nothing you don't
Six focused tools that work together instead of competing for your attention.
Structured Lessons
N5 vocabulary, kanji, and grammar taught in order, with example sentences and memory hooks for every word.
Spaced-Repetition Review
A review queue that resurfaces exactly what you're about to forget, so nothing you've learned quietly slips away.
AI Tutor
Ask questions in plain English, get explanations in context, and practice real conversation whenever you're stuck.
AI-Generated Quizzes
Mock tests generated from what you've actually studied, so practice always matches where you are.
Grammar Playground
Build your own sentences and get instant feedback from an assistant that checks your grammar, not just your vocabulary.
Adaptive Immersion
Start fully in English, then dial up Japanese-only mode as you improve — the app adjusts, you don't have to switch apps.
Your study companion for every milestone
A friendly face for streaks, reviews, and the occasional slip-up.
A simple daily loop
No decision fatigue — open the app and it tells you what to do next.
Learn
Work through a short, structured lesson introducing new vocab, kanji, or grammar.
Review
Clear your spaced-repetition queue so today's learning sticks for good.
Practice
Take an AI-generated quiz or chat with the tutor about anything unclear.
Level up
As your accuracy climbs, ZeroNihongo nudges you toward more Japanese, less English.
