Kadojo: Japanese Flashcards

Learn kanji, words and grammar

Expected Sep 28, 2026 · Free · In‑App Purchases

Pre-order now and Kadojo arrives the day it launches. Start collecting for free, take as long as you like, and upgrade only when you want more. Kadojo is a card collection. You fill it by learning Japanese. Your collection sits on one ordered route, from your very first hiragana character all the way to the top. Follow it, or go straight for the ones you want. THOUSANDS OF CARDS, MADE FOR YOU Each card arrives with its meaning, readings and example sentences, plus an illustration. Tap any card to hear it read aloud. Every card you collect is yours to keep, and it ranks up as your memory of it gets stronger. COLLECT THEM IN ORDER Vocabulary, kanji, grammar lessons and counting practice all sit on one track: hundreds of lessons, and the kanji that carry every word. Finish a step and the next one opens, so the planning is already done for you. OR GO STRAIGHT FOR WHAT YOU WANT The whole catalogue is open to browse, search and filter. Study a themed deck, revisit any lesson you have already worked through, or drill the counters, the verb forms and the time on their own. The path is there for the days you want direction, not a rail you are locked onto. ONLY YOU KNOW IF YOU KNEW A review is a single swipe: the answer came back to you, or it did not. Nothing to type, nothing to mark, nothing to get wrong. You are the only one who decides, and Kadojo plans the next review around what you tell it. REVIEWS TIMED TO YOUR MEMORY Kadojo schedules every card with a modern spaced-repetition algorithm that models how your memory fades. It tracks each direction of a card separately, so recognising a word and recalling it are treated as the two different skills they actually are. LESSONS TEACH, DRILLS PRACTISE Short, focused lessons explain a grammar point before you ever drill it. Then dedicated practice sessions put it to work, including counters and verb forms, the parts that are hardest to drill on your own. EVERYTHING CARRIES ITS LEVEL Whether you plan to sit the JLPT or not, everything on the path is labelled with one of its levels. Every card, lesson and kanji sits somewhere between N5 and N1, so you always know how hard a thing is before you start it, and you can aim straight at the level you need. WATCH YOUR COLLECTION GROW A daily activity view, and a track you can scroll back through to see exactly how far you have come and what is still waiting to be collected. YOUR COLLECTION FOLLOWS YOU Everything syncs to your account. Change phone, keep your collection. START FOR FREE The beginning of the path is free, with no countdown, no daily limit and nothing set to expire. Learn Japanese at whatever pace suits you, for as long as you like. Kadojo Premium opens the rest whenever you want it! ----- Terms of Use: https://okitori.com/terms.html Privacy Policy: https://okitori.com/privacy.html License Agreement: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
