A waterside yokai depicted by Edo-period artist Toriyama Sekien in Konjaku Hyakki Shūi. Covered head to toe in hair and armed with file-like teeth, it is shown catching fish along a riverbank. The name also appears as “Kishigai Kozō.” While it evokes kappa-type creatures, equating them requires caution. It is chiefly known as a being that exists within Sekien’s paintings, with few solid mentions in classical texts or regional lore.
Folklore & Legends
Its first attested appearance is in Sekien’s Konjaku Hyakki Shūi, where the caption simply notes it eats fish by the river. No distinct folktale type has been identified. Some have compared it to a Yamaguchi dialect creature called Takiwaro that becomes an enko (kappa) upon entering the sea, but any direct lineage is unclear. Modern reference works typically present it as a yokai originating from art, without local tradition attached.
A reconstruction based on Toriyama Sekien’s image and its brief note. It lurks along riverbanks and in shallow pools beneath cliffs, seizing fish when the moment is right. Its body is close to a small boy’s in build but covered in coarse hair, and its teeth are file-like, said to rasp flesh from its catch. While traits recalling the kappa (such as webbing and a waterside life) come to mind, definitive attributes like a carapace or head-dish are not attested and are therefore omitted. The “bank” and “cliff” elements in the name are read as descriptive of its haunt, not a regional or clan identifier. Modern commentary notes a cautious link to beings bearing “cliff” in mountain-怪 lexicon (e.g., Takiwaro), but stops short of identification. Extant primary sources are Sekien’s picture and text; no behavior, curse, or offering rites are transmitted. Here it is treated as a small waterside uncanny, silently stalking fish.
