About Kanji Detective: Japanese JLPT
Every day there's a new case: one hidden kanji, the same for every detective around the world. Question suspects, follow the clues and name the culprit. HOW IT WORKS Type a kanji, a reading or an English meaning to question a suspect. Every wrong guess uncovers another clue: • Stroke count • The kanji's category, such as Nature & weather or Body • A component it contains • A word it appears in, with the kanji hidden • An example sentence with the kanji blanked out • Its meaning and its on and kun readings • And, as a last resort, its stroke order drawn step by step Solve it with as few clues as you can. Your result is graded the way Japanese teachers mark homework. THE CASE FILE Once a case is closed, open its case file to study the kanji properly: meanings, readings with romaji, an animated stroke order, example words and real example sentences. THE CASEBOOK Every case you close goes into your casebook, with its kanji and your grade. Look back over past cases and reopen any case file to revise. Training results are filed there too, newest first, so you can revisit any kanji you've practised. BUILD A HABIT • Daily case: one kanji a day from JLPT N5–N3, free • An optional daily reminder, so you never miss a case • Streaks and statistics for every schedule • Share your result without spoiling the answer KANJI DETECTIVE PLUS A one-time purchase, with no subscription: • Cold cases: a second, harder daily case at JLPT N2–N1 • Unlimited training at the JLPT levels you choose, where kanji that stumped you come back more often • The case archive: play any daily or cold case you missed, and retrain tough ones • Shared with your family through Family Sharing PRIVATE AND OFFLINE No account, no ads, no tracking. The whole dictionary is built in, so the app works without a connection, and your progress stays on your device. Kanji data comes from KANJIDIC2, JMdict, KanjiVG, Tatoeba and other open sources, credited in the app.
