About
The Kanji Map is a Japanese language learning tool that shows kanji information and decomposition in graph form.
How to use this site
Kanji are represented with nodes and the connection between them with edges in a 2D or 3D force-directed graph. Click/tap on visible nodes or use the search field to change the selected node. If connected nodes have the same onyomi it is displayed over the link. Nodes are colored based on type: currently selected kanji, jōyō kanji, jinmeiyō kanji, neither.
Displayed kanji information (where available):
- Type: jōyō kanji (taught in school), jinmeiyō kanji (used in names) or neither
- JLPT (Japanese-Language Proficiency) Test level
- Frequency rank out of 2500 most used kanji found in newspapers
- Stroke count
- Meaning
- Kunyomi (Japanese reading of the kanji)
- Onnyomi (Chinese/Sino-Japanese reading of the kanji)
- Examples with audio, kunyomi and onyomi
- Radical with kunyomi and meaning
Changelog
- Added to go script to make kangxi/cjk compatibility radicals consistent, thanks to mochi-co/equivalent-unified-ideograph, avoiding issues like 忄 and ⺖ being mixed up as they are different unicode characters
- Reworked the data composition pipeline, radical alternative forms now have a link from the original form
- updated the data
- fixed a bug where kanji with no stroke animation were not displayed
- fixed radicals and added alternative forms with position information
- added a custom font to display radicals, thanks to KanjiVG
