The Obakemono Project

http://www.obakemono.com/index.php

A database with information and pictures of a wide variety of Japanese ghosts.

I found it to be quite interesting. And I like the style of the pictures.

Kitsune

Yuki-Onna

 I think Kitsune and Tanuki are my favourite type of Obake.

Yama-uba

山姥　（やまうば）

Mountain Hag
other names: Yamanba 山姥　（やまんば）

A female figure, sometimes considered a type of monster, thought to inhabit mountainous regions. She takes a variety of forms in art and folklore, both benevolent and malicious, and is closely related to some concepts of the Yama no Kami (the deity of the mountains).
