Also known as Zashiki bokko, they are a spirit that can appear as a child from three to twelve years old that can also be any gender. They originate from Iwate Prefecture but variations of the myth can be found across Japan. When they live in a home the family that lives there will be blessed with good fortune and bad luck will fall upon the home and it's inhabitants should the Zashiki Warashi leave. A Zashiki will never be seen until they leave the home, but their presence is known by the mischief they make. The Zashiki must be noticed, appreciated, and taken care of properly like a child or else they will leave. However, too much attention will cause them to leave as well.
