Yes. Kanjijo follows the JLPT from N5 all the way to N1 in one path: 2,480 kanji, 9,020 words and 476 grammar points, plus 95 graded reading lessons, 95 listening lessons, 80 dictation lessons and 35 full mock tests, seven for each level. It is free to download on iPhone, and you can try it in your browser on this page.
Look for an app that teaches the meaning, the readings and the stroke order together, and then makes you recall them rather than just recognise them. Kanjijo covers all 2,480 kanji up to N1 with stroke-order animation, on’yomi and kun’yomi, 885 radical stories and an exclusive mnemonic for every kanji and every word, and its seven-stage SRS brings each one back just before you would forget it.
Kanjijo is on the App Store for iPhone today, and an Android version is on the way. Until then, the phone on this page and the free tools (the JLPT level test, kana quiz, verb conjugator, listening challenge and konbini simulator) run in any browser.
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 7 new lessons per day total - one new lesson per day in each of the 7 content tracks: Kanji+Vocabulary, JLPT Hiragana, JLPT Katakana, Grammar, Reading, Listening, and Dictation. You also get JLPT mock tests, 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. Paste a link to any Japanese video and Kanjijo turns what is spoken in it into a lesson. It reads the captions and splits every sentence into individual words - written Japanese has no spaces between words, which is the single barrier that makes native material unreadable for learners - then adds furigana, underlines the words your lessons already teach, and names the grammar patterns in each line. Tap a word for its meaning, reveal an English translation of any line, and save any word or grammar point to a flashcard collection or your SRS review schedule. The word splitting and grammar detection run on your device.
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 2,400+ Kanji, 9,000+ Vocabulary, JLPT Hiragana/Katakana vocab decks, complete N5→N1 Grammar, Reading, Listening, and mock JLPT practice, all organized in sequential lessons. Start from zero or jump to your current level.
Absolutely. You can cancel your subscription at any time through the App Store. You will continue to have access until the end of your billing period. There are no cancellation fees or hidden charges.
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.
