The samebito comes from a rather different background than many of the yokai proper we’ve showcased here. Rather than originating in picture scrolls written explicitly to create yokai or in folktales incorporated into those scrolls, the samebito is a monster with a literary pedigree. The earliest record of these critters appears in a gesaku, the Edo-period equivalent of a short story. Samebito were brought to the attention of the west by Lacfadio Hearn, who did much to publicize Japanese traditions with his series of books.
I haven’t been able to find a single illustration of a samebito that matches what I’ve got in my head–I see the samebito as looking something like an anthropomorphic goblin shark.
An enormous creature stands here, a cross between an ogre and a shark. It clutches a polearm in its clawed hands. A beard of tendrils like an octopus’ arms dangles at the base of its massive jaws, and its nose points far beyond its emerald eyes.
