Tsukumogami
A tsukumogami is in Japanese folklore, a type of Mononoke, or poltergeist, that inhabits tools. Tsukumogami means “old tool spirits.” In many respects, they resemble the Brownie, as they will perform chores by themselves at night. If the tools are mistreated, neglected or discarded, however, the tsukumogami take revenge by attacking the human perpetrators at night while they sleep. There are many different tsukumogami. The hohkigami, for example, inhabit old brooms. At night they happily go about cleaning up and dusting a home.
