This was previously discussed in forum #53755, where it was proposed to introduce wagashi as an umbrella tag for Japanese confectionery such as dango, youkan_(food), mochi, etc.
However, wagashi is currently an artist tag. Suggest moving the artist to wagashi77 (blog url) or wagashi_(okashina) (blog title).
Then, implications:
- wagashi -> sweets
- wagashi -> food (?)
- dango, youkan_(food), taiyaki, mochi, sakuramochi, ichigo_daifuku, etc. -> wagashi (May need to de-implicate mochi -> food first)
While we're at it, take care of some of those individual tags as well
- alias ichigodaifuku->ichigo_daifuku
- sakura_mochi is artist 星猫, suggest move to pixiv username kiraneko (which I presume is the intended reading, as opposed to hoshineko) and then alias sakuramochi -> sakura_mochi
For dicussion: disposition of japanese_sweets tag. Existing alias wafuku->japanese clothes suggests wagashi->japanese_sweets. However I would advocate aliasing in the opposite direction to avoid being too vague, since it is useful to maintain the distinction with other Japanese snacks such as pocky. (See also: forum #61759)
