I just wanted to share a link with you:

The other day I came across this video on the Kickstarter website and found it fascinating enough to become a backer. Now I ve been receiving updates about the project regularly and I think this is awesome and it is getting better and better. In Japan, I always knew that something was there but I didn't know the name! Yokai is what I was looking all along but unable to put a name on it or to get an explanation from Japanese people. Many Japanese I met would explain saying that is too complicated to explain to foreigners
This from my limited experience anyway.
Many of this Yokai found their way into anime etc, but when I look for it, the information are sparse and vague (in English in any case)
For Japanese the references to Yokai must be very obvious but less for us.
I am happy to have found this and the drawings look very good. I wonder if the author is here in this forum somewhere ..

Nice. The illustration resembles a woodblock print. I wonder if they all will.

In case you haven't already come across these:

The Obakemono Project (English site)
Yōkai Daizukai, an illustrated guide to yōkai authored by manga artist Shigeru Mizuki, features a collection of cutaway diagrams showing the anatomy of 85 traditional monsters (Japanese book)

(Thanks for introducing me to kickstarters. What a great idea.) :-)

This book, written in English, is also a decent introduction with summaries of many Yokai:

Shigeru Mizuki also has a lot of other great youkai books in Japanese. This site also has some good info in English, as well as the other resources mentioned, and this site has great pictures, so you should be able to still enjoy it without knowing Japanese. (Yes, you can tell I'm a youkai fan too. ^-^)

EDIT: Forgot about [url="http://web.archive.org/web/20050625010958/http://www.youkaimura.org/]Youkaimura[/url]. It's all in English too.
