sukumogami (付喪神, "artifact spirit") are a type of Japanese spirit. According to the Tsukumogami-emaki, tsukumogami originate from items or artifacts that have reached their 100th birthday and thus become alive and aware. Any object of this age, from swords to toys, can become a Tsukumogami. Tsukumogami are considered spirits and supernatural beings, as opposed to enchanted items
Hyakkiyagyo - On a popular-culture level, certainly the idea of animate inanimate objects provides an entertaining and comical subject and the potential for social commentary. The most famous early images of tsukumogami appear in the playful Muromachi-period Hyakkiyagyo-emaki, but the idea has been reinvented over and over into the modern period.
