What is "zashiki-warashi"

The Zashiki-Warashi ( Japanese: 座敷童 or 座敷童子, literally "guestroom child") sometimes also called Zashiki Bokko (Japanese: 座敷ぼっこ, literally "guestroom basker") is a Yōkai (Japanese: 妖怪, variously translated as "ghoul" or "goblin") originating from Iwate Prefecture.

It is similar to the Russian folk story of the Domovoi.
