kappa4

The kappa-4 (κ₄) or kappa-four is a mythical creature from Japanese folklore. It is a type of kappa, a Japanese water sprite known for its amphibious nature and mischievous or sometimes malevolent behavior. The kappa-4 is distinguished by its particular size and strength compared to other kappa, often depicted as larger and more formidable. Like other kappa, it is said to inhabit rivers and ponds and possesses a distinctive shallow depression on its head, known as a "sara" (dish), which must be kept filled with water for the creature to retain its power and mobility on land.

Legends describe the kappa-4 as having a green, scaly skin, webbed hands and feet, and a beak-like mouth. They are often said to be fond of cucumbers and sumo wrestling. While many kappa are known for their pranks, the kappa-4 is sometimes portrayed as more dangerous, capable of dragging people and animals into the water and drowning them. Conversely, some tales suggest they can also offer medicinal knowledge or aid in irrigation if treated with respect or appeased. The specific characteristics and stories surrounding the kappa-4 can vary regionally within Japan, reflecting the diverse nature of folklore.
