Kanji API
The Japanese kanji writing system as an API — every Jōyō, Kyōiku and Jinmeiyō kanji with its on/kun readings, English meanings, JLPT level, school grade, stroke count and newspaper frequency. Look up a single kanji (e.g. 字 → grade 1, JLPT 4, readings ジ / あざ, meanings "character, letter"), find every kanji that shares a kana reading (e.g. かじ), list the vocabulary that uses a given kanji, or pull a whole standard set (Jōyō 2,136 · Kyōiku · grade-1…grade-6 · Jinmeiyō) with paging. Backed by the open KANJIDIC2 / JMdict datasets via kanjiapi.dev. Ideal for Japanese-learning and flashcard apps, SRS/Anki-style study tools, furigana and reading aids, language-education platforms and linguistics research.
