Keukegen (毛羽毛現, Keukegen) is a yokai illustrated in Toriyama Sekien's "Konjaku Hyakki Shūi", that resembles a small dog covered entirely in long hair. The Keukegen is also considered a disease spirit which lives in damp, dark places and causes people in the house to get sick.


Keukegen are particularly filthy monsters commonly found in populated areas. They are the size of a small dog, and appear simply as a mass of long, dirty hair. They make their homes in cool, damp, dark places, and are particularly fond of living under floorboards and around run-down homes, where stuffiness, moisture, and lack of human activity create the perfect breeding place for sickness.

Despite their apparent cuteness, keukegen do not make good pets. They are actually a kind of minor spirit of bad luck, disease, and pestilence. They bring sickness and bad health to those whom they live near. Generally they try to avoid human contact, being shy by nature, and are rarely seen. However, their proximity is apparent when members of a household mysteriously begin to contract sickness or bad luck. They are easy to avoid, however, as keep away from clean, kempt houses.

Keukegen’s name is a pun. It is commonly written with characters that mean “a hairy fluffy sight,” but can also be written with different characters that mean “rare and dubious.” Unsurprisingly, these creatures are rarely seen directly, and those who claim to have seen them are often accused of imagining it. Though while keukegen may be hard to see, the sickening effect of their presence is very obvious.
