Oni
One of the most well-known aspects of Japanese folklore is the oni, which is a sort of mountain-dwelling ogre, usually depicted with red, blue, brown or black skin, two horns on its head, a wide mouth filled with fangs, and wearing nothing but a tigerskin loincloth. It often carries an iron club or a giant sword. Oni are mostly depicted as evil, but can occasionally be the embodiment of an ambivalent natural force. They are, like many obake, associated with the direction northeast.
