In Japanese folklore, an old household object believed to become animate is called a tsukumogami.
Tsukumogami are objects that have reached an advanced age and acquired a spirit or personality. Popular explanations often associate this transformation with an object surviving for 100 years, although the exact age threshold is a later and simplified convention rather than a universal rule in every historical source.
The idea is closely connected with Japanese attitudes toward objects, use, neglect, and impermanence. A discarded tool, utensil, instrument, or piece of clothing might become mischievous or resentful after being treated carelessly. Illustrated yōkai scrolls and later popular culture helped develop and spread these memorable object spirits.
Tsukumogami is a broad category, not the name of one individual creature. Karakasa-obake, the animated umbrella with a single eye and leg, is one famous example often associated with the tradition. The concept is also frequently used in manga, anime, and games.
