Gangikozō (岸涯小僧 or がんぎこぞう, Gangikozō) is a creature from Japanese folklore.
Gangikozō are hairy, monkey-like water spirits which inhabit rivers. They live along the riverbanks, where they hunt fish. Their bodies are covered in hair, and the hair on their head resembles the the bobbed okappa hair style once popular among children in Japan. Their most notable features are their webbed hands and toes, and their long teeth which are sharp and jagged like files. They are close relatives of the much more well-known kappa.
Gangikozō are not encountered outside of the riverbanks, and there may be a good reason for this; according to one theory, they are a transitional form of kappa. According to many legends, kappa transform from river spirits into hairy mountain spirits when the seasons change. The specific details differ quite a bit from place to place. However, in Yamaguchi prefecture, there is a hairy mountain spirit called a takiwaro which transforms into a water spirit called an enko (a variety of kappa). Some folklorists believe that the gangikozō is a kind of takiwaro, and thus is merely a transitional form of a kappa. This would explain why so little is known of them.
Gangikozō normally stay away from people, but occasionally encounter fishermen along the rivers they inhabit. When meeting a gangikozō, fishermen often leave their largest, cheapest fish on the riverside as an offering.
Gangikozō do not appear in any local legends, though stories of very similar-looking yokai do. The first and only written record of them is in Toriyama Sekien’s yokai encyclopedias. It is therefore possible that gangikozō was made up by Toriyama Sekien based on the numerous legends of transforming kappa.
According to Mizuki Shigeru, the name gangikozō can be written with another set of kanji, 雁木小僧. These characters can mean “stepped pier” or “gear tooth” depending on the context. This writing reflects both the habitat of the gangikozō as well as its mouth full of sharp teeth, which resembles a toothed gear.
