Alternate Spellings: Wani Yuu Dou
Etymology – Umbrella Ghost
The Kasa-Obake of Japan are an unusual type of ghost or yokai. Sometimes, the Kasa-Obake are considered a tsukumogami, those human tools that have managed to survive long enough and have absorbed enough energy to become animated, sentient beings. In this case, the Kasa-Obake is an old umbrella that has managed to reach 100 years old.
This yokai is described as an umbrella with one eye that jumps around one leg with it’s sole foot wearing a wooden sandal or geta. Other descriptions will give the Kasa-Obake two arms and possibly two eyes. In addition, the yokai is sometimes shown as having a long tongue. In the Hyakki Yagyo Zumaki text or yokai emaki, the Kasa-Obake are shown to have two feet instead of one.
Behavior wise, the Kasa-Obake is seen as a playful, child-like trickster that loves to frighten people.
In Japanese folklore, the tsukumogami are human tools, that over a period of time, often months and years are capable of becoming yokai. By having survived that long, that tsukumogami has gained and absorbed enough energy to become sentient as well as animated.
In the case with the Kasa-Obake, they are umbrellas that have survived one hundred years of use before becoming yokai.
Where there have been many types of tsukumogami yokai, the Kasa-Obake is the one that seems to have become the most well-known of this variety.
A Made Up Yokai
Edo Period – The Kasa-Obake with the classical appearance of being an umbrella with one eye and foot comes from this era. What I find cool, is that there is an old card game known as Obake Karuta (“Ghost” or “Monster Cards”) that people would play, wherein the players try to collect the most cards in order to win. The game is clearly a predecessor to the more modern Pokemon and Yu-Gi-Oh! Card games that people collect and showcase different, various monsters.
Hyakumonogatari Kaidankai – Or “The Gathering of One Hundred Supernatural Tales”, is another game popular during the Edo period. In this game of telling ghost stories, the Kasa-Obake likely originates from the need for story-tellers to come up with another, new story about yokai to fulfill the needs of this game with having one hundred ghosts. In other words, the Kasa-Obake is very likely made up.
Ansei Period – A board game from this era, called Mukashi-banashi Yōkai Sugoroku, the Kasa-Obake is shown and given the name of Sagazaka no Ippon Ashi or “One-footed from Sagizaka.”
Variations On A Theme
There are a couple of other very similar yokai that are also described as umbrellas, though they’re not the Kasa-Obake.
Higashiuwa Region – In the Ehime Prefecture, there is a story of a rain umbrella yokai that appears in the valleys on rainy nights. Those who are unfortunate to see this yokai are unable to move their feet as they cower before it. I’m not sure how that could be, unless there is some supernatural effect going on.
Hyakki Yagyo Emaki – Dating from the Muromachi period, the yokai found in this text or scroll have a more humanoid appearance and have umbrellas on their heads.
Mizokuchi Region – In the Tottori Prefecture, what is now the Hōki, Saihaku District, the Yureigasa or “Ghost Umbrella” also has one eye and foot much like the Kasa-Obake. They are said to go out on extremely windy days and blow people up into the skies.
Kasa-Obake continue their presence into the modern era with appearances in a good many, various video games, anime and manga; especially any making use of yokai.
