well, by glancing at the wikipedia page, they're not shapeshifters so they wouldn't be on the list. However, I'm sure you could probably have a character lean towards ice-based magic and become a vaguely similar creature. Could definitely be some kind of Yanamun, if you want it to be malicious. Since the kappa and jorogumo are associated with water, it could be a Yanamun form of one of those, perhaps.

Everything I have is fairly tentative, so there's always room for adjustment as long as it fits in the same spirit.
