Ohachi Sue/Origin

Origin
Ohachi Sue is a yōkai belonging to the folk tradition of the Ainu people living in Sakhalin. The name means "guardian of the empty house." It is customary for the Ainu people to live near the coast to fish from spring to summer and move to another dwelling in the winter when the weather gets colder. It is said that the Ohachi Sue sneaks into their houses and lives there while the houses are unoccupied.

The Ohachi Sue is commonly imagined as assuming the shape of a hairy old man, wearing crude clothing made from fish skin. It is violent by nature and carries around a very sharp sword. It is said that countless men and animals alike have fallen prey to this sword.
