Yokai Name Generator

Yokai names are mostly descriptions. Japanese folklore rarely gives a spirit a personal name; it gives it a label that says what it looks like or what it does. Rokurokubi is "pulley neck," Nurikabe is "plaster wall," Azukiarai is "bean washer," Kuchisake-onna is "slit-mouthed woman." The recurring building blocks are a body or creature word (onna, otoko, kozō, bōzu, nyūdō, baba, jijī, kubi, te, me), an object or place (kasa, chōchin, kawa, yama, tenjō) and a quirk (nuri, nure, furari, betobeto). Stack two or three and the result sounds like it came out of Toriyama Sekien's 1776 picture scrolls.

The famous exceptions are named individuals: the ogre lord Shuten-dōji, the fox Tamamo-no-Mae, the tengu king Sōjōbō, the jealous serpent Kiyohime, the ghost Oiwa. These usually carry honorific endings such as -dōji, -hime, -bō or -no-Mae, or they are simply an ordinary human name that became infamous. Regional yokai add a place in front (Nekomata of Nabeshima, Kappa of the Tone River), and tsukumogami, the hundred-year-old objects that wake up, take the object's name plus -no-sei or -obake.

This list mixes the canon bestiary, the legends, regional variants and new coinages that follow the same grammar. Pick a genuine yokai when readers should recognize the creature, and an original compound when you want something traditional-sounding that belongs to your world.
