Kappa (河童)

A creature that seems to have hauled itself up from the riverbed. The name is said to derive from *kawawappa* — "river child" — worn smooth by generations of mouths into *kappa*, though the thing itself shifts its name with the landscape: Garappa in Kyushu, Kawako in Izumo, Enkō in Suō, and more than eighty other epithets soaked into the waterways of the archipelago. There is scarcely another creature of its kind that answers to so many names.

It is most commonly described as bearing a shallow dish of water atop its head, a tortoise-like shell upon its back, and skin of a greenish cast. Yet in certain western provinces it is said to wear the face of a monkey — and strangely, those very same regions preserve traditions in which the kappa and the monkey are sworn enemies. The contradiction is never resolved. Only the rumour goes on drifting across the water's surface.

Among folklorists, a persistent theory holds that the kappa is a water deity fallen from grace. A god who once guarded the rivers and brought rich catches, who slipped — as faith in it waned — from an object of reverence into something merely grotesque. The traces of that former dignity still flicker in such lingering divine titles as Kawako Daimyōjin in Izumo and Suiko-sama in Aomori.

Observe the proper courtesies and it will do nothing worse than challenge you to a wrestling match. Offer it disrespect, however, and it is said to draw out the *shirikodama* — a mysterious vital essence — through its victim's body. The old texts grow deliberately vague on what, precisely, this entails. Whenever a drowned body was pulled from the river, the village elders would quietly lower their eyes.

Even now, each summer when accidents multiply along the water's edge, the name passes in low whispers from parent to child, from teacher to pupil. It is spoken as a warning. Yet one cannot shake the feeling that the very act of whispering it across the surface of the river is, somehow, calling something back.
