Displeased, Takeiwatatsu-no-mikoto cut off his head. The head rose into the sky and brought frost on the land until it was warmed by a bonfire.

- Onihachi lived in Chichi Cave at the foot of Mt. Nijou. He forcibly took Unome-hime (also known as Asara-hime), daughter of Inari-hime, as his wife and hid her.

- (From the Miyazaki Legends) Similar to the Takeiwatatsu-no-mikoto story, he angered Aso-myoujin of Higo by picking an arrow up with his foot. His wife Asara-hime, an incarnation of a dragon from Mitai, rebelled against him at the behest of Mikeirino-no-mikoto (Mikenu-no-mikoto), whereupon Tabe Shigetaka and others subjugated him, cut him into pieces, and buried the parts in three separate places.

- (From Takachiho) He was a demon who lived in a cave until he was killed by a son of Emperor Jimmu, who cut him to pieces and buried him in three separate places.

- (Also from Takachiho) His real name was Hashiritakeru, a giant spider. He ruled Takachiho, harried the people, and violently carried off beautiful women.
