There is a myth about the origin of Hyottoko. In the story, there was a boy with a bizarre face who could create gold out of his belly button, so when someone died in a house, you would put the mask of this boy at the top of the fireplace to bring good fortune to the house. The name of the boy was Hyoutokusu .This is considered one of the possible names that lend plausibility to the origin of Hyottoko.
In some parts of north eastern Japan, Hyottoko is regarded as the god of fire.
