Learn Japanese by reading
Iyaku is one place to read, study and write Japanese: graded readers from the easiest up, the Irodori course, flashcards on one spaced-repetition schedule, and a notebook for your own text. Tap any word for its reading, meaning and grammar.
What's in it
- Today — pick up where you left off: your study session, the books, notes and decks you had open.
- Library — hundreds of free graded readers, sorted by difficulty, and courses: Irodori and kanji story decks.
- Notebook — paste or write Japanese, read it with furigana, study it.
- Decks — your flashcards: kanji, words, sentences and listening, with writing drills.
You don't need an account. Everything works signed out and is kept on your device; sign in to sync it between your devices (your progress so far comes with you).
Free, and Iyaku Plus
All content is free — every book, course, deck and study mode.
Iyaku Plus ($5 / month) is for what runs an AI model on your behalf: the speaking tutor, Hands-Free study, dictation, photo-to-text (OCR) and Notebook tasks. That's the only thing it adds, and the only thing that costs money. See Iyaku Plus.
