Japanese dictionary data

This service uses JMdict and KANJIDIC2. Copyright belongs to James William Breen and the Electronic Dictionary Research and Development Group (EDRDG). Dictionary-derived readings, meanings, and example vocabulary, including our adaptations of that data, are available under CC BY-SA 4.0.

We selected entries and English glosses, combined reviewed vocabulary, and organized entries into study categories. These are unofficial study assignments, not an official JLPT kanji list.

Full KanjiVG license. The kanji template data also includes source, revision, license, and modification notices.
