DATA / LEVELS
Kanji Branch Study refers to public dictionary data for vocabulary and readings. Classification labels help learners choose a practice range, but they are supplementary study information and not an official complete test list.
Vocabulary and reading information refers to public dictionary data including KANJIDIC2, JMdict, and JmdictFurigana. The tool organizes kanji, words, readings, and furigana from these sources into a form suitable for the learning screen.
School-grade references and JLPT N5-N1 labels help learners estimate difficulty and choose a practice range. JLPT labels are supplementary learning classifications. They are not an official complete syllabus, an official test range, or a guarantee of passing.
The official guide pages and learning tool currently do not display ads. If ads are introduced later, they will be considered only as a way to support continued operation of the free learning tool, without obstructing the learning flow. Relevant privacy and cookie information will also be updated.
