Learn Japanese kanji with drawing practice and swipe flashcards. Study characters by JLPT level, understand their readings and meanings, and see your progress grow one session at a time.
PRACTICE YOUR WAY
Trace kanji with stroke guidance to practice writing, or swipe through cards to review recognition. Use hints when you need help and choose kana or romaji readings to suit your level.
STUDY FROM N5 TO N1
Browse kanji by estimated JLPT difficulty, from N5 to N1, or by Jōyō school grade. Start with a ready-made list, save favourites, or create your own lists for focused practice.
UNDERSTAND EACH CHARACTER
Explore meanings, on’yomi and kun’yomi readings, name readings, radicals and stroke counts. Add your own notes and look up characters as you learn.
