Sharekobe (Osaka)

Sharekobe is a yokai in which a skull moves on its own, speaks, and curses; bleached bones left in the open acquire spirit and become a yokai. The figure stands within the lineage of departed-soul and bone yokai of the unburied dead. The figure recurs in early-modern kaidan in fields, on old battlefields, in graveyards, and at the roadside. The canonical narrative comes in two strands: a traveller on a dark mountain road kicks a rolling skull, which cries "ouch"; alternatively, a traveller buries an abandoned skull, and later receives a visit from the bone to give thanks. Old battlefields and execution-ground sites form the typical setting, with cases dense across the medieval Kinai battlegrounds including Osaka and Kyoto. Toriyama Sekien's Konjaku Gazu Zoku Hyakki (1779) gives cognate figures, and the Konjaku Monogatari-shu volume 27 records cognate setsuwa. Noh plays Nomori and Izutsu carry skull-themes. The Ehon Hyakumonogatari (Toyama Mitsunobu/Sawaki Sushi, 1841) includes karmic-tale figures with commentary. Murakami Kenji's Nihon Yokai Daijiten (Kadokawa, 2005) and the Nichibunken Strange Phenomena and Yokai Folklore Database systematize the cases. Adjacent dead-and-bone yokai include kyokotsu and gashadokuro; the reply-and-thanks narrative shares lineage with the Tohoku nobusuma and the Kanto yagyo-san. Osaka and Kinai records are limited; the entry is preserved as a typical early-modern kaidan of battlefield, execution-ground, and graveyard.
