Credits
The kanji and vocabulary in KanaDrill are not ours. They come from dictionaries and published standards that other people built and shared, and the licences those carry ask to be named here. This page is that, and it is also just a thank you — none of the drilling beyond kana would exist without them.
Dictionaries
- JMdict and KANJIDIC2, from the Electronic Dictionary Research and Development Group — the word readings and meanings, and the kanji readings and meanings. Used under CC BY-SA 4.0 , per the EDRDG licence statement .
The data files we derive from these carry the same share-alike licence. If we ever offer them for download, they go out under CC BY-SA 4.0.
Kanji parts
- How each kanji is put together — which parts it is built from, and where they sit — from cjkvi-ids , based on the CHISE IDS database. Used under the GNU GPL v2 .
- Which characters are radicals, from the Unicode Character Database's EquivalentUnifiedIdeograph.txt , under the Unicode License .
The parts data is GPL rather than share-alike, so if we ever offer it for download it goes out under the GPL v2, separately from the dictionary files.
Levels
- JLPT vocabulary and kanji lists by Jonathan Waller, used under CC BY.
- The same lists matched to JMdict by stephenmk/yomitan-jlpt-vocab , which ties each of Waller's words to its dictionary entry and its most common spelling. Used under CC BY-SA 4.0 .
- 学年別漢字配当表 — which kanji are taught in which school year — from Japan's Ministry of Education (MEXT), published as part of the Course of Study.
- 常用漢字表 — the standard readings for the 2,136 everyday-use kanji — a 2010 Cabinet notice.
One thing worth saying plainly: the JLPT levels are an estimate. The test has published no official vocabulary or kanji lists since 2010, so Waller's lists are a careful reconstruction that the rest of the ecosystem has settled on — not the exam's syllabus. Treat “N5” here as “about N5”.
The school-grade levels are not an estimate. That table is a published standard, and grades 1–6 are the 1,026 kanji it lists.
Typefaces
- Klee One — the Japanese face, used wherever a glyph is the thing being learnt.
- Hanken Grotesk — everything else.
- Sono — the monospaced labels and keys.
