1. Joyo, school, and Kanken ranges
The catalog normalizes the Agency for Cultural Affairs Joyo Kanji table and MEXT school-grade data. Kanken labels come from the grade column in 日本漢字表 (250212).xlsx. Verified readings and representatives cover all 5,663 characters from Kanken 10 through 1; sourced dictionary representatives are used only where the Culture Agency table has no official example.
2. Readings, meanings, and examples
Japanese readings and English meanings use KANJIDIC2/JMdict-based artifacts. Korean Hanja labels use the MIT-licensed HanjaDict with reviewed exceptions, while Korean example glosses prioritize reviewed data and Korean Wiktionary. Chinese glosses prioritize Tomoshi, and selected multilingual glosses use localized Wiktionary extracts from Kaikki.org. Every example retains provenance.
3. Stroke vectors
Stroke-order SVG paths come from KanjiVG by Ulrich Apel under CC BY-SA 3.0. Keep the original attribution and license when redistributing.
4. Fonts and external licenses
Fonts follow their providers’ SIL Open Font License terms. Original source pages and full license text are available from the respective providers.
5. JLPT comparison method
JLPT publishes no official kanji-by-kanji list. kanjikaki orders the 2,136 Joyo characters by MEXT school grade, then by KANJIDIC2 frequency within each grade, and assigns non-overlapping study bands: N5 100, N4 200, N3 350, N2 350, and N1 1,136. Advanced non-Joyo characters remain unclassified. These are learning estimates, not official JLPT levels.
