Kadojo: Japanese Flashcards

Kadojo is a card collection. You fill it by learning Japanese.
Your collection sits on one ordered route that starts at your very first hiragana character and runs all the way to the top. Follow it, or go straight for the cards you want.

🎴 WHAT YOU COLLECT

• Thousands of Japanese cards, each with its meaning, readings, example sentences and an illustration
• Hiragana and katakana, taught character by character, before any kanji appears
• Kanji, introduced where the words you are learning need them
• Hundreds of grammar lessons, each one followed by a drill that puts it to work
• Counters, verb forms and telling the time, drillable on their own
• Tap any card to hear its pronunciation read aloud

🧠 HOW IT WORKS

• One swipe per review. The answer came back to you, or it did not. Nothing to type, nothing to mark, nothing to get wrong.
• A modern spaced repetition system (SRS) schedules every card around how your memory fades, and puts each review at the moment it does the most good.
• Each direction of a card is tracked separately, so recognising a Japanese word and recalling it count as the two different skills they actually are.
• Every card you collect is yours to keep, and it ranks up as your memory of it gets stronger.

🗺️ FOLLOW THE PATH, OR MAKE YOUR OWN

Japanese vocabulary, kanji, grammar lessons and counting practice all sit on one track. Finish a step and the next one opens, so the planning is already done for you...
... Or ignore it. 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.

🎯 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. Everything syncs to your account, so you can change phone and keep your collection.
