Enkō

Go west in Japan and the kappa grows fur.

The enkō is the water-child of the Chūgoku region, Hiroshima, and Shikoku, and it is recognisably the same creature as the kappa with the dial turned toward monkey. It's hairy. It's about the size of a three-year-old. It has long limbs and claws, and its skin is slick — the accounts say slimy, like a catfish.

One reportedly captured specimen was described as red-faced, with human-like feet and hands it could pull back into itself.

It drags swimmers under. And what it takes is not quite what the kappa takes.

The western version is bloodier

The kappa's famous theft is the shirikodama — a small ball or organ, reached for through the anus, often described as holding the soul. It's grotesque, but it's also faintly abstract, and the roundness of it lets people tell the story as a curiosity.

The enkō takes the *iki-gimo — the living liver* — by the same route.

No euphemism. Not a mysterious spiritual pearl but an organ you have, extracted while you're alive.

That's older and nastier, and it's consistent with the region. Western Japan wants livers. The great ape-monster of the same area is a liver-eater too. Whatever folk-medical or folk-anatomical belief is running under that, it shows up in the western monsters and not the eastern ones.

The enkō can also appear as a woman, which the kappa mostly cannot.

It's a rank, not a species

This is the part that changes how you read the whole family.

In Tosa there's a water-sprite called the shibaten, and on festival days the shibaten becomes an enkō. In Yamaguchi there's the takiwaro, which becomes an enkō after spending three years moving between the mountains and the rivers.

So "enkō" isn't just a regional word for kappa. It's what a junior water-sprite gets promoted to, with time served or on the right date.

Which means western Japan's water-children are best drawn not as a list of species but as an org chart — a career ladder with grades, where the enkō is the senior post and the little local sprites are working toward it.

That's a genuinely unusual structure. Most yokai categories are flat. This one has seniority.

It owns a river

The last thing, and it's my favourite.

There's a river in Minami Ward, Hiroshima, called the Enkō-gawa — the enkō's river. It's named after the monster. There's an Enkō bridge. The name is on street signage and in addresses, used daily by people who are not thinking about water monsters at all.

And the city still holds the Enkō River Kappa Festival, with the old custom of floating cucumbers on the water on the sixth day of the sixth lunar month — the same tribute paid to kappa across the country, still being handed over.

A creature that pulls livers out of swimmers has ended up as a municipal place-name and an annual community event with a food offering. Of all the ways to survive into the present, becoming the name of a bridge people cross on their way to work is not the worst.
