The Myth
Koiyamainu appears in the second part of Kyokutei Bakin’s tale Musobe Kocho Monogatari. It is described as one of the strange beings found in Bonnoukyo, a distant foreign land visited by the story’s protagonist.
The creature is said to resemble a beast with the face of a human — sometimes that of a woman — while its long, loose hair trails down its back like a tail. Its appearance is unsettling, caught somewhere between person and animal.
Koiyamainu wanders while crying out in a mournful voice. Its call sounds like, “I want to see you, I want to see you — owwow, owwow.” The cry echoes through the land, filled with longing and sorrow.
Its name reflects this nature: a play on the idea of lovesickness and that of a diseased or troubled dog. The creature’s lament expresses yearning for someone absent, its voice carrying the pain of desire that cannot be fulfilled.
