TRANSLATION: river otter
HABITAT: rivers, wetlands, freshwater bodies
DIET: carnivorous; feeds on fish and small animals, with a fondness for sake
APPEARANCE: River otters can be found in the wilds all over Japan. They are under a meter in total length, and well-loved for their shy, playful nature and cute faces.
BEHAVIOR: As with most wild animals in Japan, kawauso develop magical powers upon reaching old age. They are particularly skilled at shape-changing and accurately copying sounds. They love alcohol, and are usually only seen in human areas when trying to acquire sake. They are playful yokai, well known for tricks and mischief, but very rarely dangerous.
INTERACTIONS: Kawauso are fond of playing pranks on humans, especially by mimicking sounds and words. They enjoy calling out human names or random words at strangers walking in the street and watching their confused reactions. They are fond of magically snuffing out lanterns in the night and leaving travelers stranded in the dark. Others transform into beautiful young women and try to seduce young men, and then run away laughing.
Occasionally kawauso do commit more violent deeds. In a few instances near castles in Ishikawa, a kawauso dressed up as beautiful young woman was found luring men to the water’s edge in order to catch and eat them, discarding the half-eaten bodies into the moat.
OTHER FORMS: A Kawauso’s favorite disguise is the form of a young beggar child wearing a big straw hat. They use this child form to sneak into towns and try to buy alcohol from shops. The ruse often falls apart when the disguised creature is asked who it is, or where it came from. Caught off-guard, it simply repeats the last word spoken to it, or makes funny nonsensical noises, ruining its disguise and giving away its supernatural nature.
