Sumi: Learn Japanese Kanji
Flashcards, Kana & JLPT N5–N1
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: stroke order for every kanji and kana, writing practice that checks each stroke, and a writing quiz.
Learn Japanese from your first kana to N1 kanji. Sumi brings characters, readings, vocabulary and audio together in a focused flashcard app for iPhone and iPad.
START WITH THE SOUNDS
Learn the 46 basic Hiragana and 46 basic Katakana characters with pronunciation guidance and audio. Continue with voiced sounds, combinations, small kana and other advanced lessons. Extra vocabulary shows sounds in words when you want more context.
ONE KANJI, SEVERAL READINGS
Study 2,136 kanji from N5 to N1 in chapters of up to ten. Turn over a card to see its meanings, on and kun readings, and related words. Expand readings and examples right on the card.
WRITE EVERY STROKE
Watch the stroke order of every kanji and kana, step through it stroke by stroke, and see which parts a kanji is built from. Practice writing with your finger or Apple Pencil: each stroke is checked for direction, place and order, with a hint when you need one. The writing quiz asks you to write kanji from memory.
READ AND LISTEN IN CONTEXT
See Japanese example sentences with hiragana, romaji and English translations. Listen to individual words or the whole sentence, with highlighting that follows the speech.
KNOW WHAT TO PRACTICE
Test readings and meanings with quizzes. Rate what you recall to schedule reviews, and return to words that need more practice. Track your progress without losing sight of the next card.
