They are a yōkai that would steal corpses from funerals and cemeteries, and what exactly they are is not firmly set, and there are examples all throughout the country. In many cases their true identity is actually a cat yōkai, and it is also said that cats that grow old would turn into this yōkai, and that their true identity is actually a nekomata.
There are tales of kasha in tales like the folktale Neko Danka etc., and there are similar tales in the Harima Province (now Hyōgo Prefecture), in Yamasaki (now Shisō), there is the tale of the "Kasha-baba."
As a method of protecting corpses from kasha, in Kamikuishiki, Nishiyatsushiro District, Yamanashi Prefecture (now Fujikawaguchiko, Kōfu), at a temple that a kasha is said to live near, a funeral is performed twice, and it is said that by putting a rock inside the coffin for the first funeral, this protects the corpse from being stolen by the kasha. Also, in Yawatahama, Ehime, Ehime prefecture, it is said that leaving a hair razor on top of the coffin would prevent the kasha from stealing the corpse. In Saigō, Higashiusuki District, Miyzaki Prefecture (now Misato), it is said that before a funeral procession, "I will not let baku feed on this (バクには食わせん)" or "I will not let kasha feed on this (火車には食わせん)" is changed twice. In the village of Kumagaya, Atetsu District, Okayama Prefecture (now Niimi), it is said that a kasha is avoided by playing a myobachi (妙八) (a traditional Japanese musical instrument).
Kasha in classics
- "Concerning How in the Manor of Ueda, Echigo, at the Time of Funeral, a Lightning Cloud Comes and Steals Corpses" from the "Kiizō Danshū" (奇異雑談集)
- In funerals performed in Ueda, Echigo, a kasha appeared during the funeral presence, and attempted to steal the corpse. It is said that this kasha appeared together with hash lightning and rain, and in the book's illustration, like the raijin, it wears a fundoshi made with a tiger's skin, and is depicted possessing a drum that can cause lightning (refer to image).
- "Holy Priest Onyo Himself Rides with a Kasha" from the "Shin Chomonjū (新著聞集)," Chapter Five "Acts of Prayer"
- In Bunmei 11, July 2, at the Zōjō-ji, Holy Priest Onyo was greeted by a kasha. This kasha was not an envoy of hell, but rather an envoy of the pure land, and thus here, the appearance of a kasha depended on whether or not one believed in the afterlife.
- "Looking at a Kasha, Getting Sore at the Waist and Legs, and Collapsing" from the "Shin Chomonjū", Chapter Ten "Strange Events"
- It was at the village of Myōganji near Kisai in Bushū. One time, a man named Yasubei who ran an alcohol shop suddenly ran off down a path, shouted "a kasha is coming," and collapsed. By the time the family rushed to him, he had already lost his sanity and was unable to listen to anything said to him, fell asleep, and it is said that ten days later, his lower body started rotting and he died.
- "Cutting the Hand of an Ogre in a Cloud at the Place of Funeral" from the "Shin Chomonjū", Chapter Ten "Strange Events"
- When a warrior named Matsudaira Gozaemon participated in the funeral procession of his male cousin, thunder began to rumble, and from a dark cloud that covered the sky, a kasha stuck out an arm of one like a bear, and attempted to steal the corpse. When it was cut off by a sword, it was said that the arm had three dreadful nails, and was covered by hair that looked like silver needles.
- "A Kasha Seizes and Takes Away an Avaricious Old Woman" from the "Shin Chomonjū", Chapter Fourteen "Calamities"
- When a feudal lord of Hizen, the governor of Inaba, Oomura, and several others, were going around the seacoast of Bizen, a black cloud appeared from afar, and echoed a shreik, "ah, how sad (あら悲しや)," and a peron's feet stuck out from the cloud. When the governor of Inaba's retinue dragged it down, it turned out to be the corpse of an old woman. When the people in the surroundings were asked about the circumstances, it turned out that the old woman was terribly stingy, and was detested by those around her, but one time when she went outside to go to the bathroom, a black cloud suddenly swooped down and took her away. To the people of that society, it was the deed of a devil called "kasha."
- "Kasha" from the "Bōsō Manroku" (茅窓漫録)
- It would sometimes happen that in the middle of a funeral procession, rain and wind would suddenly come forth, blow away the coffin, and cause the corpse to be lost, but this was due to how a kasha from hell came to greet it, and caused people to be afraid and feel ashamed. It is said that the kasha would tear up the corpse, hang it on rocks or trees in the mountains. In the book, there are many kasha in Japan and in China, and here it was the deed of a beast called 魍魎, and in the illustration, it was written as 魍魎 and given the reading "kuhashiya" (refer to image).
- "Priest Kitataka" from the Hokuetsu Seppu
- It was in the Tenshō period. At a funeral in the Uonuma District, Echigo Province, a sudden gust and a ball of fire came flying to it, and covered the coffin. Inside the ball of fire, was a giant cat with two tails, and it attempted to steal the coffin. This yōkai was repelled by the priest of Dontōan, Kitataka, by his incantation and a single strike of his nyoi, and the kesa of Kitagawa was afterwards called the "kasha-otoshi no kesa" (the kesa of the one who defeated a kasha).
Similar things to kasha
Things of the same kind as kasha, or things thought of as a different name for kasha, are as following.
In Tōno, Iwate Prefecture, called "kyasha," at the mountain next to the pass that continued from the village of Ayaori, Kamihei District (now part of Tōno) to the village of Miyamori (now also part of Tōno), there lived a thing that took on the appearance of a woman who wore a kinchaku bag tied to her front, and it is said that it would steal corpses from coffins at funerals and dig up corpses from the gravesites and eat the corpses. In the village of Minamimimaki, Nagano Prefecture (now Saku), it is also called "kyasha," and like usual, it would steal corpses from funerals.
In the Yamagata Prefecture, a story is passed down where when a certain wealthy man died, a kasha-neko (カシャ猫 or 火車猫) appeared before him and attempted to steal his corpse, but the priest of Seigen-ji drove it away. What was then determined to have been its remaining tail was then presented to the temple of Hase-kannon as a charm against evil spirits, which is open to the public on new years each year.
In the village of Akihata, Kanra District, Gunma Prefecture (now Kanra), a monster that would eat human corpses are called "tenmaru," and in order to defend against this, the bamboo basket on top was protected.
In Japan, from old times, cats were seen as possessing supernatural abilities, and there are legends such as "one must not let a cat get near a corpse" and "when a cat leaps over a coffin, the corpse inside the coffin will wake up." Also, in the collection of setsuwa tales, the Uji Shūi Monogatari from medieval Japan, a gokusotsu (an evil ogre that torments the dead in hell) would drag a burning hi no kuruma (wheel of fire), it is said that they would attempt to take away the corpses of sinners, or living sinners. It has thus been determined that the legend of the kasha was born as a result of the mixture of legends concerning cats and the dead, and the legend of the "hi no kuruma" that would steal away sinners.
There is also the theory that the legend of kappa making humans drown and taking their butts (eating their innards from their butts) was born as a result of the influence of this kasha. Also, in China, there is the legend of the yōkai called wangliang, but as it is said that they like to eat the inneards of people's corpses, it is seen that in Japan, this was mixed up with the kasha that would steal corpses in Japan, and in addition to how in the aforementioned "Bōsō Manroku," the characters 魍魎 were read "kuhashiya," in the essay Mimibukuro by Negishi Shizumori, in volume four "Kiboku no Koto" (鬼僕の事), there is a scene under the name, "The One Called Mōryō" (魍魎といへる者なり).
Re-usage of the term
In the region of the Harima Province, old women with bad personalities are said to be called "kasha-baba" ("kasha old women"), with the nuance that they are old women that are like bakeneko.
How the yarite, the woman who controls the yūjo in the yūkaku, is called "kasha" (花車, "flower wheel") comes from this kasha, and as the yarite was the woman who managed everything, and how the word "yarite" is also used to indicate people who move bullock carts (gissha or gyūsha) also comes from this.
