This is a set of Japanese characters for item creators and editors, to save time and allow drag and drop of pre-made characters into your own meshes. No credit or whatever needed.
The prefabs go in the prefab folder and the items go in the items folders, obviously.
There's three objects included showing all three categories (Hiragana, Katakana and a limited number of Kanji), but the main purpose for these is as a prefab rather than as a model for the map itself.
A primary goal was to make sure that filesize is kept to an absolute minimum since these are detail assets, so they aren't really designed to be blown up to a really large size.
