They are also called "karakasa-obake" (から傘おばけ),[2][4] "kasa-bake" (傘化け),[5] and "karakasa kozō" (唐傘小僧).
[3] Sometimes, but rarely, they even have two feet, as depicted in the yōkai emaki such the "Hyakki Yagyo Zumaki".
[2] Literature about them are not accompanied by folktales, and thus they are considered to be a yōkai that appear only in made-up stories[10] or exist only in pictures.
[5] These are not kasa-obake, but in folktales, as an umbrella yōkai, in the Higashiuwa region, Ehime Prefecture, there is a story that a rain umbrella would appear in valleys on rainy nights, and those who see it would cower and not be able to move their feet.
[7] Also, in Mizokuchi, Tottori Prefecture (now Hōki, Saihaku District), there is a yōkai called yūreigasa (幽霊傘, "ghost umbrella") that has one eye and one foot like the kasa-obake, but it is said that on days of strong wind, they would blow people up into the skies.
