Learn Japanese Kanji
Effortlessly

SRS (Spaced Repetition System) is a learning technique that optimizes review intervals based on how well you know each Kanji or Vocabulary item. Items you struggle with appear more often, while mastered items are shown less frequently. This is scientifically proven to maximize long-term memory retention — the most effective way to learn and remember thousands of kanji characters.

Free users get full access to ALL learning content — nothing is permanently locked. The free plan unlocks 6 new lessons per day total — one new lesson per day in each of the 6 content tracks: Kanji+Vocabulary, JLPT Hiragana, JLPT Katakana, Grammar, Reading, and Listening. You also get unlimited SRS reviews, home screen and lock screen widgets, OCR scanning, writing practice, statistics, and exclusive kanji + vocab mnemonics. A short rewarded ad plays before each new lesson, but never during your study.

Point your camera at any Japanese text — books, signs, menus, manga, or handwritten notes. Kanjijo instantly recognizes the characters using on-device OCR technology and shows detailed flashcards for every word detected. You can save scanned words to your personal collection for later review. All processing happens on your device, so your data stays private.

Yes! Kanjijo offers both home screen and lock screen widgets for iOS. A new Kanji or Vocabulary word appears throughout the day, helping you learn Japanese passively without even opening the app. Tap the widget to instantly open the full flashcard with readings, meanings, and pronunciation.

Kanjijo teaches Kanji, Vocabulary, and Kana in a unified learning path with sequential unlocking. Unlike Anki, you don’t need to create decks yourself — everything is ready-made and organized by JLPT level. Unlike WaniKani, Kanjijo includes vocabulary, pronunciation, writing practice, and OCR scanning — all for free. Each card includes funny mnemonics, radical breakdowns, and native pronunciation. You must pass proficiency tests before advancing, ensuring true mastery.

Kanjijo covers all five JLPT levels: N5 (beginner), N4, N3, N2, and N1 (advanced). You get 2,000+ Kanji, 8,000+ Vocabulary, JLPT Hiragana/Katakana vocab decks, and the complete N5→N1 Grammar curriculum, all organized in sequential lessons. Start from zero or jump to your current level.

Yes. Your data is encrypted both on your device and in the cloud using industry-standard AES-256 encryption. OCR scanning is processed entirely on-device. We never sell or share your personal data with third parties.
