Japanese “obake”

Here’s a great website with information about some of the huge variety of different ghosts and monsters in traditional Japanese mythology, all explained in English with lovely illustrations:
The Obakemono Project

“Obakemono” (お化け物) is the honorific “o” plus “bake” (to change or corrupt) and “mono” (thing). Some of the monsters from traditional tales are more humorous than scary-seeming, but this site is a great resource for those of you interested in the mythology!
