The Japanese bookstore chain, Kinokuniya, has a branch I go to in San Francisco. There they have a section labeled "Ghosts and Demons". It is my favorite section of any bookstore anywhere. I've pillaged it multiple times and amassed a big pile of mind bogglingly bizarre and beautiful art. It was hard to pick out just a few pictures to share here. Just about every page of all those books are filled with images like these.
