Karakasa-Kozou is a yokai said to be an old Japanese umbrella (wagasa) that has transformed into a supernatural creature. It is most commonly depicted with a single large eye, a long tongue hanging out, and hopping on one leg, though some illustrations show it with two legs or arms. The earliest umbrella yokai images appear in Hyakki Yagyō Emaki picture scrolls of the Muromachi period. From the Edo era onward, the image became established through kusazōshi (illustrated books), ukiyo-e prints, karuta cards, and stage performances. Although direct oral traditions are scarce, Karakasa-Kozou is considered one of the most iconic examples of tsukumogami (animated household objects) that became famous mainly through visual representation.
