Dreaded by fishermen, this enormous sea monster can tower as much as thirty meters over the surface of the ocean. Descriptions of the umi-bōzu are various, but most commonly it appears as just the top of a great black head as smooth and hairless as a monk's, with slippery black skin and huge glowing eyes.¹ Fishing is scarce when this beast is around, and it has been known to capsize boats and drag people into the sea.²
