40) Japan - 17. Karakasa-kozo

Known as 'Karakasa', 'Kasabake', or 'Kasa-obake', this is an umbrella yokai commonly depicted with one eye on the umbrella, a long red tongue, and arms attached to a single leg. In Muromachi period scrolls of the Hyakki Yagyō (Night Parade of One Hundred Demons), it's shown as a human-like oni wearing a folded umbrella on its head. The form we know today was popularized in Edo period art and kabuki, and has been passed down since. It simply hops around on one leg at night, startling people, but doesn't directly attack them. Despite being a well-known yokai appearing in various Japanese media, there are few specific legends or folktales passed down in particular regions, apart from brief records like 'an umbrella yokai appeared in a certain area'. Yokai researchers apparently regard it as the endpoint of yokai that have 'been freed from the fear of ghost stories and started to be consumed as characters'.
