Simple process

How Kanjijo Works

Seven simple steps to Japanese mastery.

Choose Your Level

Pick your JLPT level (N5–N1) or start with Kana. Content is organized into bite-sized lessons across Kanji+Vocab, JLPT Hira/Kata vocab, Grammar, Reading, Listening, and Dictation.

Study Flashcards

Learn Kanji, Vocabulary, Hira/Kata and Grammar through interactive flashcards with readings, meanings, exclusive mnemonics for kanji and vocab, and example sentences.

Take Tests

Complete lesson tests to unlock the next lesson, then use JLPT mock tests to practice timing and find weak sections.

Review with SRS

Smart algorithm schedules reviews at the perfect time: right before you forget.

Learn Passively

Add the home screen widget, lock screen widget and interactive test widget. Kanji and vocab silently appear all day so you absorb them without even opening the app.

Everything you learn goes into a seven-stage review garden that grows from Seed to Ancient Tree.

Yes. Paste a link to a YouTube video with Japanese subtitles and Kanjijo turns each line into something you can study: it splits the sentence into words, adds furigana, marks the words your lessons already teach and names the grammar patterns.

Yes. Point your camera at a sign, a menu, a book page or a screen and Kanjijo reads the Japanese on your phone, then shows the kanji, words and grammar it contains with their readings and meanings. The recognition runs on the device, so the photo is not uploaded.
