More fun stuff here with the Gashadokuro… hmm, maybe fun isn’t the right word:
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 of starvation or in battle, without being buried. 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.
The Gashadokuro is a yōkai that first appeared in print in the later half of the 20th century. It was created by the authors of shonen magazines published from 1960 – 1970 and illustrated yōkai encyclopedias. Shigeaki Yamauchi’s World’s Bizarre Thriller Complete Works 2: Monsters of the World (Akita Shoten, 1968) compiled articles about yōkai by Saitō Ryokuu. At the same time, it was also picked up by Shigeru Mizuki and Satō Aribumi, and from their introduction the Gashadokuro became more widely known from 1980 on.
The illustration in Arabumi’s Illustrated Encyclopedia of Japanese Yōkai (1972) and the illustration by Mizuki both base the appearance of the Gashadokuro on the giant skeleton in Utagawa Kuniyoshi’s ukiyo-e print, Takiyasha the Witch and the Skeleton Spectre. It has no direct connection to the Gashadokuro, but is said to have influenced modern depictions. Kuniyoshi’s print was commissioned in the Edo period by Santō Kyōden for a yomihon, depicting a scene in which Taira no Masakado’s daughter, Takiyasha-hime, summons a skeleton yōkai to attack the samurai Ooya Tarou Mitsukuni. Although originally described as many life-sized skeletons, Kuniyoshi depicted it as a single giant skeleton, as is characteristic of his work.
In the entry for Gashadokuro in Mizuki’s book, a related tale from the Nihon Ryōiki is introduced. It tells of a man in Bingo Province (Hiroshima Prefecture) who is in a field at night and, hearing an eerie voice moaning, “My eye hurts,” finds a skeleton there with a bamboo shoot growing from its eye socket. He removes the bamboo shoot and offers the skeleton dried boiled rice, upon which the skeleton tells him the story of its murder and its personal history, and rewards him for his kindness. Though this tale has been conflated with that of the Gashadokuro, the two are in fact unrelated, the Gashadokuro having originated in the later half of the 20th century.
