A kappa (河童, "river-child")—also known as kawatarō (川太郎, "river-boy"), komahiki (駒引, "horse-puller"), with a boss called kawatora (川虎, "river-tiger") or suiko (水虎, "water-tiger")—is a reptiloid kami with similarities to yōkai found in traditional Japanese folklore. Kappa can become harmful when they are not respected as gods. They are typically depicted as green, human-like beings with webbed hands and feet and a turtle-like carapace on their back.
The kappa are known to favor cucumbers and love to engage in sumo wrestling. They are often accused of assaulting humans in water and removing a mythical organ called the shirikodama from their victim's anus.
The name kappa is a contraction of the words kawa (river) and wappa, a variant form of 童 warawa (also warabe) "child". Another translation of kappa is "water sprites". The kappa are also known regionally by at least eighty other names such as kawappa, kawako, kawatarō, gawappa, kōgo, suitengu.
It is also called kawauso 'otter', dangame 'soft-shelled turtle', and enkō 'monkey', suggesting it outwardly resembles these animals. The name komahiki or "steed-puller" alludes to its reputed penchant to drag away horses.
The kappa has been known as kawako in Izumo (Shimane Prefecture) where Lafcadio Hearn was based, and gatarō was the familiar name of it to folklorist Kunio Yanagita from Hyōgo Prefecture.
Kappa are said to be roughly humanoid in form and about the size of a child, inhabiting the ponds and rivers of Japan. Clumsy on land, they are at home in the water, and thrive during the warm months. They are typically greenish in color (or yellow-blue), and either scaly or slimy skinned, with webbed hands and feet, and a turtle-like carapace on their back. Inhuman traits include three anuses that allow them to pass three times as much gas as humans. Despite their small stature they are physically stronger than a grown man.
The kappa are sometimes said to smell like fish, and they can swim like them.
According to some accounts, a kappa's arms are connected to each other through the torso and can slide from one side to the other. While they are primarily water creatures, they do on occasion venture onto land. When they do, the "dish" on their head can be covered with a metal cap for protection.
A hairy kappa is called a hyōsube.
Kappa are usually seen as kami of the water. Their actions range from comparatively minor misdemeanors, such as looking up women's kimono if they venture too near to water, to outright malevolence, such as drowning people and animals, kidnapping children, raping women and at times eating human flesh. Though sometimes menacing, they may also behave amicably towards humans. While younger kappa are frequently found in family groups, adult kappa live solitary lives. However, it is common for kappa to befriend other yōkai and sometimes even people.
Folk beliefs claim the cucumber as their traditional favorite meal. At festivals, offerings of cucumber are frequently made to the kappa. Sometimes the kappa is said to have other favorite foods, such as the Japanese eggplant, soba (buckwheat noodles), nattō (fermented soybeans), or kabocha(Japanese pumpkin).
In Edo (old Tokyo), there used to be a tradition where people would write the names of their family members on cucumbers and send them afloat into the streams to mollify the kappa and prevent the family from coming to harm in the streams. In some regions, it was customary to eat cucumbers before swimming as protection, but in others it was believed that this act would guarantee an attack.
A cucumber-filled sushi roll is known as a kappamaki.
As water monsters, kappa have been blamed for drownings, and are often said to try to lure people into water and pull them in with their great skill at wrestling. They are sometimes said to take their victims for the purpose of drinking their blood, eating their livers, or gaining power by taking their shirikodama (尻子玉), a mythical ball said to contain the soul, which is located inside the anus.
Kappa have been used to warn children of the dangers lurking in rivers and lakes, as kappa have been often said to try to lure people to water and pull them in. Even today, signs warning about kappa appear by bodies of water in some Japanese towns and villages.
Kappa are also said to victimize animals, especially horses and cows. The motif of the kappa trying to drown a horse is found all over Japan.
Lafcadio Hearn wrote of a story in Kawachimura near Matsue where a horse-stealing kappa was captured and made to write a sworn statement vowing never to harm people again.
In many versions the kappa is dragged by the horse to the stable where it is most vulnerable, and it is there it is forced to submit a writ of promise not to misbehave.
It was believed that there were a few means of escape if one was confronted with a kappa. Kappa are obsessed with politeness, so if a person makes a deep bow, it will return the gesture. This results in the kappa spilling the water held in the "dish" (sara) on its head, rendering it unable to leave the bowing position until the plate is refilled with water from the river in which it lives. If a person refills it, the kappa will serve that person for all eternity. A similar weakness of the kappa involves its arms, which can easily be pulled from its body. If an arm is detached, the kappa will perform favors or share knowledge in exchange for its return.
Another method of defeat involves shogi or sumo wrestling: a kappa sometimes challenges a human being to wrestle or engage in other tests of skill. This tendency is easily used to encourage the kappa to spill the water from its sara. One notable example of this method is the folktale of a farmer who promises his daughter's hand in marriage to a kappa in return for the creature irrigating his land. The farmer's daughter challenges the kappa to submerge several gourds in water. When the kappa fails in its task, it retreats, saving the farmer's daughter from the marriage. Kappa have also been driven away by their aversion to iron, sesame, or ginger.
Kappa are not entirely antagonistic to human beings.
Once befriended, kappa may perform any number of tasks for human beings, such as helping farmers irrigate their land. Sometimes, they bring fresh fish, which is regarded as a mark of good fortune for the family receiving it. They are also highly knowledgeable about medicine, and legend states that they taught the art of bone setting to human beings. There are also legends that Kappa will save a friendly human from drowning.
Along with the oni and the tengu, the kappa is among the best-known yōkai in Japan.

Shrines are dedicated to the worship of kappa as water deity in such places as Aomori Prefecture or Miyagi Prefecture. There were also festivals meant to placate the kappa in order to obtain a good harvest, some of which still take place today. These festivals generally took place during the two equinoxes of the year, when the kappa are said to travel from the rivers to the mountains and vice versa.

The nearby Jōkenji In Tōno, there is a Buddhist temple that has komainu dog statues with depressions on their heads reminiscent of the water-retaining dish on the kappa's heads, said to be dedicated to the kappa which according to legend helped extinguish a fire at the temple.

Similar folklore can be found in Asia and Europe. The Japanese folklore creature Kappa is known in Chinese folklore as 神水 shuǐguǐ "water-ghost", or water monkey and may also be related to the kelpie of Scotland and the nixie of Scandinavia.

This is not entirely surprising, as the area is not only close to Poland and Czech Republic, but also home to the Slavic minority of the Sorbs.
