Looking at Resources for learning Japanese, I don't see much in terms of calligraphy.
Things I'm looking for are:
- Calligraphy datasets: stroke shapes and order, samples of handwritten characters, etc. The only two resources I know of are kanjiVG and GlyphWiki. The latter is more about typefaces, though, so practically there is only one dataset. Maybe there is something similar to the MNIST database of handwritten digits for kanji.
- National standards. For example, 常用漢字表 has a section dedicated to stroke shapes, sizes, variants, etc. However, I can't find anything similar to ГОСТ 2.304-81 which defines shapes of symbols which is required for blueprints and other engineering drawings. Specifically:
- Is there a calligraphy standard taught in Japanese schools? (Publicly available - would be extremely useful for beginners.)
- Is there any standard (by any definition) font?
- Is there any standard font for writing with a ball pen? (In contrast to traditional brushes.)
- Explanatory/tutoring materials, which, rather that just listing samples of characters, demonstrate important features (e.g. explain why relative stroke length is important, like in 未 vs 末), list common mistakes. Since calligraphy is taught in Japanese schools, I think that teachers must have some kind of materials like this, rather than just keeping all the information inside their "mind palaces".
- Resources dedicated to various calligraphy styles: regular, cursive, seal scripts. So far the best I've seen is moji.tekkai.com (suggested by @virmaior)
If it's possible to gather some of those resources, it would be a great addition to Resources for learning Japanese.
