For reference when I'll need it! Some of you will find it useful. Quickly snapped this from other site as they are a few names I did not know. More to be said and to explore. Will try to compile everything when the time comes.
Akaname Creatures that clean bathrooms with their tongues. .
Bakeneko A cat with supernatural abilities, sometimes possessing a tail split in two (in which case it is called nekomata). Kirara from the anime "InuYasha" is a bakeneko, as is the pokemon Espeon. See Wikipedia.
Fu (or Foo) Dogs Chinese Imperial guardian lions. See Wikipedia or Everything2. Can also refer to Pekingese dogs. Also, there is a talking Shar-Pei in the cartoon "American Dragon: Jake Long" whose name is Fu Dog. I don't know that there's any relation to either Imperial guardian lions or Pekingese, but I thought I'd mention it, anyway.
Gaki Hungry ghosts. A kind of vampire described in Japanese Buddhism (also called Preta), they may feed on things like blood, feces, or corpses. See Wikipedia.
Hanyou Half human, half demon. The anime character "Inuyasha" is a hanyou. See Wikipedia.
Harionago A youkai woman with hair she can control with her will, to use as a weapon. Yura from the anime "InuYasha" is a harionago (though she might also be considered atsukumogami). See Wikipedia.
Hitodama Souls of the departed which appear as glowing spheres. See Wikipedia.
Kappa A kind of Japanese water imp. Also the inspiration for a cucumber sushi called kappamaki (see food page). Kappa somewhat resemble turtles, and like to suck out people's insides. But they can be defeated by making them spill the water which rests in a bowl-like indentation on their heads. Or they can be bribed with cucumbers. See Wikipedia or Everything2.
Kasa-obake Paper umbrella monster, a type of tsukumogami. See Wikipedia.
Kirin Mythical creature which is a cross between a dragon, deer, and lion. Very lucky. In China it is called qilin (see Wikipedia). The Japanese name, Kirin, can also mean giraffe. See Kirin's Lair on Everything2. There's a Japanese beer named for the creature.
Kitsune Fox youkai, often possessing nine tails. The pokemon Vulpix and Ninetales are kitsune, as is Shippo in the anime "InuYasha." There's also a kitsune locked inside the title character in the anime "Naruto." See Wikipedia or Everything2.

Shikigami Protective spirits which can be summoned (or created) by onmyoji or Shinto priests and priestesses. both Kikyo and Tsubaki from the anime "InuYasha" created shikigami. See Wikipedia.
Shinigami Death gods. There are lots of shinigami (or "soul reapers") in the anime "Bleach," and Botan from the anmie "Yu Yu Hakusho" could also be called a shinigami. And there are shinigami in plenty of other anime and manga... See Wikipedia.
Tengu Japanese goblins, which may be benevolent or malicious. Most often they would punish arrogant monks, priests, or samurai who misused their power. May derive from the Chinese Tien Kou (or Tiangou). See Japanese Buddhist Statuary, Wikipedia or Everything2.

Yosei Fairies. Today's concept has been influenced by Western mythology, but they were more traditionally depicted as birds. See Wikipedia.
