Kappa
The kappa is the water imp of Japan’s rivers and ponds: child-sized, with a beak, a shell, webbed hands and a hollow on its head that holds the water of its strength. It drags people and horses into the water, and loves cucumbers and sumo.
Meaning
Kappa means “river child”, and the creature has other names by region, among them kawatarō and kawako (JAANUS). The JAANUS dictionary of Japanese art describes a kappa about the size of a young boy, covered in green scales, with a snout, bobbed hair, webbed hands and feet, and a saucer-like hollow on top of its head that holds water: when the water runs low, its powers fail. The National Diet Library says kappa lurk in rivers and ponds, pull children and horses into the water and flood the fields beside them. Some regions think kappa helpful, JAANUS notes, but their reputation is mostly malicious. In Shinto terms, the Encyclopedia of Shinto counts the kappa, with snakes and dragons, among the beings that stand for the water kami (suijin): dangerous to people, but also thought to bring wealth and blessings.
Origin and history
Henri Joly, in 1908, placed the kappa in the rivers of Kyūshū and gave it the body of a tortoise, the limbs of a frog and the head of a monkey, with a hollow in the skull holding the fluid of its strength. He also gave the old way to beat one. The kappa is ferocious but very civil, so a person who bows to it politely is bowed to in return, as deeply and as often, and the kappa spills its fluid and loses its strength. Joly quotes an older encyclopedia describing it as like a child of three or four, scaled all over its back, hiding its long claws in the water, and tells of a kappa caught by a horse’s belly-band in the river at Kawachi village and made to sign a bond never again to attack any man, woman, child or beast. Kappa illustrations, JAANUS adds, are frequent in Edo-period anthologies of supernatural tales, and kappa often turn up in comic paintings.
The kappa and the thunder god
In Utagawa Hirokage’s print series Clowning Around at Famous Places in Edo, the National Diet Library notes, kappa try to pull the God of Thunder, who has fallen off Ryōgoku Bridge, into the river: the god of Raijin and Fūjin.
Kappa in netsuke
Joly describes kappa netsuke that show the whole creature or, more often, its head with lank straight hair, and some carvers who simply carve a child with gnarled limbs and a saucer-shaped hollow on its head. It is often shown with a cucumber.
Kappa in modern Japan
The folklorist Kunio Yanagita’s The Legends of Tōno, tales handed down in Iwate Prefecture, has kappa among its yōkai, and Mizuki Shigeru, the author of the Kitarō manga, drew some of his yōkai from Yanagita’s study, Isao Adachi writes in Japan Spotlight. Adachi’s kappa is the folklore one: child-sized, with a short bill, a shell on its back and webbed fingers, it sneaks into villages from the river and seizes livestock. On Amami Ōshima, the Japan Tourism Agency describes a local cousin, the kenmun, a red-eyed creature the height of a child that, like the kappa, has a hollow on its head holding the liquid of its power and loves to challenge people to sumo.
