Kanji Builder · 漢字組立
Interactive components
Build meaning from pieces
Learn how familiar Kanji can be separated into visual components, then rebuild them from an English clue and Japanese audio.
These are memory-friendly visual breakdowns. They do not claim every component is an official dictionary radical or give the character’s historical origin.

Skill scores · スキル成績
How your Japanese skills are developing
Each score emphasises current memory strength. Accuracy and the number of tested words are shown alongside it so small samples are not misleading.
Scores become more reliable as you practise more words. A lower score identifies a useful study opportunity—it is not a grade.
Learning history · 学習履歴
What you've studied, and when
Each entry is a session you completed — the words it covered, and the date. Redo any of them to review that exact set of words again.
