Nyoi Jizai (Will-at-Will Scepter Spirit)

Their soul is listening — speak, and they will answer.

Basic Description

A utensil-spirit depicted by Edo-period artist Toriyama Sekien in Hyakki Tsurezure Bukuro. It is a nyoi or ruyi—an ornamental scepter used by Buddhist clergy—that, after long years, acquires spirit power. Its name plays on the nyoi’s ability to reach “where one wishes,” like a backscratcher, and images show variants: a flying nyoi sprouting wings, or a form with elongated arms and claws scratching a person’s back. These iconographic types build on Muromachi-period Night Parade scrolls that already portrayed nyoi as yokai.

Folklore & Legends

Sekien glossed it: “The nyoi reaches exactly where one itches,” exaggerating a backscratcher’s function into a monster’s trait. Night Parade scrolls show a brown, long-clawed figure beside a fan-spirit, and also a winged nyoi in flight. Later commentators class it as a tsukumogami; some warn its claws can injure the careless. Specific locales or oral tales are unclear—its tradition rests chiefly on pictorial sources.

Tsukumogami

Tools and vessels used over long years are said to acquire spiritual life and transform when discarded and neglected, becoming beings known as tsukumogami. In the Muromachi-period "Tsukumogami Emaki", it was preached that tools transformed after a hundred years; the scroll depicted old implements, thrown away during house-cleaning, marching in a procession on the night of Setsubun holding grudges against humans. In the Edo period, Toriyama Sekien synthesized this worldview in his "Hyakki Tsurezure Bukuro" (The Illustrated Bag of One Hundred Random Demons), bestowing charming yokai forms upon individual objects such as biwa lutes, shamisen, koto, tea kettles, sutra scrolls, masks, and book carts, woven together with wordplay and historical anecdotes. Gathered here are the souls inhabiting tools, reflecting human sentiments—used, forgotten, yet impossible to fully discard.

Detailed Analysis

A consolidation based on the nyoi monster depicted in Muromachi-period Night Parade of One Hundred Demons scrolls and on Toriyama Sekien’s Hyakki Tsurezure Bukuro images and captions. Following the tsukumogami belief that tools gain spirit with age, the nyoi’s original function of “reaching at will” is exaggerated as occult power. Two iconographic lines exist: one shows a humanoid with a tea-brown body and long claws that scratch a person’s back with extended arms, the other shows the nyoi itself sprouting wings and drifting in midair. Both appear late at night in bedrooms or Buddhist rooms, said to seek out itchy spots and places the hand cannot reach. Some readings hold that the morally wanting are left with claw marks, yet region-specific oral lore is scant, and the figure relies mainly on pictorial sources and later yokai commentaries.
