Quote from Narvuntien »I don't quite get Kamigawa, why is everything spirits and why are spirits monstrous twisted weird things?
Japanese mythology. The main hangup people tend to have with Kamigawa in that respect is it's based on historical Japanese mythology rather than pop Japanese mythology. It'd be the equivalent of "Creature - Angel" when the art shows a giant flaming wheel with a ton of eyes. Historically accurate, but doesn't quite meet audience expectations.
