I was planning on adding this to the new version of the site, but due to the problems the site has had lately I decided to accelerate the development and release it now, as my way of saying sorry.
Practicing writing kanji is very helpful in memorization and for learning to recognize handwritten Japanese. I hope that this will be a useful resource for everyone. The stroke order diagrams should be available for most kanji that you will come by in daily life.
The data comes from the excellent KanjiVG project (http://kanjivg.tagaini.net/) by Ulrich Apel. The data is freely available under the Creative Commons Attribution-Share Alike 3.0 license. I have also released the Ruby script that I made to convert the KanjiVG data to the format that you see on the site. You can look at it here: https://github.com/Kimtaro/kanjivg2svg. The repository also includes the SVG files I generated with the script.
When I saw this, I was motivated to donate to your project. I was using another site to check stroke order, and now this consolidates my bookmarks a little more. Thanks for the great work.
Very nice! This is awesome :D Writing kanji with pencil (havn't tried brush :P) is quite intresting, it feels so much closer to culture: writing the correct strokes in right order defined by culture and tradition. I can see why calligraphy is considered an art.
These stroke diagrams are great. They are much easier to follow than the animated diagrams that Jim Breen is using over in his site. I come over to Jisho.org just to look at those.
