Just thought I’d share a type of Japanese yōkai/oni I was reminded of when reading stuff about “The Tall Gentleman”. They are called Takaonna (Tall Woman) & are pretty obscure. I’ve only ever found four or five stories about them. However, their basic story is that they start out as mortal women who become so jealous of a situation that they turn into this creature capable of stretching out their bodies to look in to tall windows & spy on the cause of their jealousy (such as adulterous husbands, women who are prettier than them, etc). Also, they eat people. Sometimes they eat the person who is cause of their jealousy (such as the adulterous husband or the lady the husband chose to sleep with) and sometimes they just eat people whose loss will somehow spite or cause pain to the person who caused their jealousy (such as all the persons servants, or all of their children).
This picture I’ve submitted is from the first in a series of e-hon (picture/art books) called “Gazu Hyaki Yagyō” (The Illustrated Night Parade of a Hundred Demons) illustrated in 1776 by Toriyama Sekien. Definitely worth a look at the related wiki (set as the click through link) for more interesting illustrations and brief descriptions.
