鯢魚 Hanzaki are monstrous versions of the Japanese giant salamander. These animals normally grow up to one and a half meters long, however the yōkai versions of this animal can grow much larger. They have rough, mottled, brown and black skin, tiny eyes, and enormous mouths which span the entire width of their heads. They live in rivers and streams far from human-inhabited areas. Hanzaki and humans rarely come into contact with each other. When they do, it is usually because the hanzaki has grown large enough to eat humans or livestock and is causing trouble to nearby villagers.
