Kappa (河童)

§Appearance

A kappa (河童, かっぱ) is usually described as a child-sized water being with webbed hands and feet, a beaked or pointed mouth, and a shell across its back. Its defining feature is the water-filled dish, or sara (皿), in the crown of the head. As long as the dish remains full, the creature keeps its unusual strength. If the water spills, it weakens and may even die.

Edo-period books such as Wakan sansai zue (1712) preserve less settled forms as well, including hairy and ape-like river creatures. Over time, artists such as Hokusai, Kuniyoshi, and Yoshitoshi helped fix the more familiar turtle-like and frog-like image. That later form is the one most often seen in festivals, river warnings, and yōkai art today.

§Interactions

Kappa are notorious for challenging humans to sumō, snatching at horses near riverbanks, and dragging the unwary into deep water. In harsher folklore they seize the shirikodama (尻子玉), a mythical organ believed to lie within the body. Because of these attacks, the kappa becomes a powerful warning figure in stories told to children and in cautionary lore around rivers and ponds.

The same tradition also preserves more reciprocal encounters. A kappa is often said to be obsessively polite, so a person who bows may cause it to bow back and spill the water from its sara. Once subdued, it may swear a written oath not to harm the village, bring gifts of fish, help with irrigation, or teach bone-setting and medicine. This double character, dangerous water predator and troublesome neighbor, is one reason the kappa remains central in Japanese folklore.

The standard kappa belongs most securely to Edo-period folklore and encyclopedic writing, even though earlier forms such as kawarō appear in early modern lexical sources. Kaibara Ekken's Yamato honzō (1709), Terashima Ryōan's Wakan sansai zue (1712), and Koshigaya Gozan's Butsurui shōko (1775) are among the clearest early anchors for its textual history. Together they show the kappa moving from scattered local descriptions toward a more widely shared image and name.

Scholars such as Kunio Yanagita, Shinobu Orikuchi, and Eiichirō Ishida argued that the kappa preserves older layers of water-deity belief, especially in places where it is placated like a local suijin (水神). That reading helps explain why some districts treat it as a dangerous yōkai while others honor it with offerings, shrines, or seasonal rites. The result is not one unified monster, but a nationwide family of water beings gathered under one famous name.

One of the best-known regional settings for kappa lore is Kappabuchi in Tōno, Iwate, where Kunio Yanagita recorded beliefs and stories in Tōno Monogatari (1910). There the creature is tied to a specific river pool, temple memory, and local cautionary storytelling. That close attachment to place helped make Tōno one of the best-known modern centers of kappa tradition.

Elsewhere, legends often follow a recognizable pattern. A kappa tries to drag off a horse or person, is captured after losing the water in its head dish, and then redeems itself by leaving fish, healing the sick, or submitting a written pledge. Izumo traditions preserved by Lafcadio Hearn keep this oath motif under names such as kawako. In Kyūshū, the creature also appears in festival performance and in stories about Kuzenbō, a chief of river spirits. These local stories keep the kappa tied to particular waterways even as the figure became a national icon.
