USING LANGUAGE TEACHER
How quizzes, heatmaps, placement, and study tools work — same questions as on our homepage.
Placement is continuous — every quiz refines your estimates. For a full Japanese Jōyō kanji pass:
- ~2,136 Jōyō kanji in the catalog
- ~3 sec/question ≈ 1h 45m for a full sweep
- ~5 sec/question ≈ 3h for a full sweep
- Accurate estimates emerge surprisingly early
- Pause and continue anytime — speedrun mode picks up where you left off
