What it does
Learn all JLPT kanji levels N5–N1 — no sign-up required. Writing tests, reading tests, flashcards, and speed drills work instantly. Free account unlocks FSRS spaced repetition and progress. I built Kanji Mastery because most kanji platforms lock core learning features behind paywalls. Unlike WaniKani, the core study tools (flashcards, tests, and spaced repetition) are completely free. Premium only unlocks advanced analytics. More features are planned!
Learn Japanese kanji online for free — practice all JLPT levels N5 to N1 with writing tests, reading quizzes, flashcards, spaced repetition, and speed drills. No sign-up required.
Master every JLPT kanji from N5 to N1 with writing tests, reading tests, and spaced repetition. No sign-up required to start. Our Smart Review system uses the FSRS-6 algorithm to schedule each kanji at the perfect time — right before you'd forget it. It tracks three memory variables per card: difficulty , stability , and retrievability , so easy kanji fade into long intervals while tricky ones are drilled more often. Optional premium tools for learners who want more structure: planning, mistake-fixing workflows, deeper insights, and personalised weak-spot practice. Kanji browsing, writing tests, reading tests, flashcards, and speed drills all work without an account . Only features that…from kanji-mastery.com
