Gashadokuro
Utagawa Kuniyoshi, "Souma no furudairi (相馬の古内裏)" also known as "Takiyasha the Witch and the Skeleton Spectre".
Gashadokuro (がしゃどくろ, literally "starving skeleton," also known as Odokuro) are mythical creatures in Japanese mythology.
Mythology:
The Gashadokuro are spirits that take the form of giant skeletons and are fifteen times taller than an average person, said to be created from the amassed bones of people who died ofstarvation. These Yōkai roam after midnight, grabbing lone travelers and biting off their heads to drink their spraying blood. There is a tell sign as the victim would hear the sound of loud ringing in the ear. The Gashadokuro are said to possess the powers of invisibility and indestructibility; though Shinto charms are said to ward them off.
