The Myth

Furuya no Mori is a mysterious and terrifying entity in a widely known Japanese folktale. Its name literally refers to a leak in an old house, where rainwater drips through a damaged roof. Although it is not necessarily a real monster within the story, its name becomes so frightening that even dangerous animals and thieves believe it must be a terrifying supernatural being.

The tale begins on a rainy night, when an old man and woman are resting in their house. A ferocious animal, often described as a tiger or wolf, enters the area intending to steal or attack their livestock. A thief also sneaks into the house, hoping to take advantage of the darkness. Inside, the old couple complain about the Furuya no Mori, speaking as though it is far more frightening than tigers and wolves and lamenting that it has come again that night.

The animal overhears their conversation and becomes terrified. Believing that a creature more powerful and dangerous than itself must be nearby, it trembles in fear. At the same moment, the startled thief falls from the ceiling onto the animal’s back. The animal assumes that the thief is the dreaded Furuya no Mori and bolts away at full speed, carrying the terrified thief with it.

Eventually, the thief manages to escape from the animal but falls into a deep hole from which he cannot climb. A monkey comes to investigate and lowers its long tail into the hole. The thief grabs the tail, hoping to pull himself out, but he clings so tightly that the monkey’s tail breaks. According to this version of the story, this explains why monkeys have short tails.

The details vary between regional versions. The animal that fears Furuya no Mori may be a tiger, wolf, wild boar, badger, or baboon. Some versions feature a supernatural creature such as Yamajiji, while others use imaginary animal names resembling combinations such as “tiger-wolf” or “lion-wolf.” When the story features a tiger, an animal not native to Japan, some versions explain its presence by placing the story in China or Korea, or claim that tigers once fled Japan because they were frightened of Furuya no Mori.

The entity’s name also changes according to local dialects. Many alternatives refer to a leaking roof in an old house, while some stories leave its nature vague, describing it simply as something terrifying. In other versions, the tiger or thief explicitly mistakes the supposed entity for a monster. One unusual variant from Taki District in Hyōgo Prefecture replaces the mysterious leak with a persimmon: a crying child is threatened with being eaten by a tiger, but when the child stops crying after receiving a persimmon, the tiger becomes frightened of the fruit, believing it to be more terrifying than itself.

Furuya no Mori is an example of a folktale in which fear arises from misunderstanding rather than from an actual monster. The old couple are referring to an ordinary household problem, but the intruders interpret their words as evidence of a terrible creature. The resulting confusion turns a harmless leak into a source of supernatural terror. The tale has been widely transmitted throughout Japan, with a written version recorded in the 1768 collection Kidan Isshō under the title Yarou Kai. Similar stories involving frightened animals, mistaken identities, and thieves caught in the confusion are also found in China, Korea, Mongolia, India, and elsewhere.

Dorotabo

by

Tradition: Japanese Mythology
Alternative Names: Mud Monster
Category: House dweller

The Myth

Dorotabo is a mud-covered humanoid monster described in a modern Japanese ghost story featured in Shin Mimibukuro, a collection of contemporary supernatural accounts by Hirokatsu Kihara and Ichiro Nakayama, published in 1998. In the story, a woman working for a publishing company in Kanda Jimbocho is warned by her editor-in-chief not to work through the night. When she asks why, he answers simply: “It’s Dorotabo.”

According to the story, people who sleep in the building are repeatedly awakened by a terrible stench. Beside their pillows stands a human-shaped figure with a body covered in mud, or one that appears to be made entirely of mud. The creature’s presence is accompanied by an overpowering foul smell that makes the encounter deeply unpleasant.

Those who attempt to touch Dorotabo discover that its body behaves unnaturally. When a person puts a hand into the muddy figure, the hand becomes sucked into its body. Even after pulling free, the person finds that the terrible smell remains. By the time they look around again, the creature has disappeared, leaving only its lingering odour as evidence of its presence. The account states that most of the male employees working at the company at the time had witnessed the phenomenon, and that they had long called the creature Dorotabo.

The name comes from an older Japanese yokai associated with rice fields. The artist Toriyama Sekien depicted this figure in Konjaku Hyakki Shūi, a collection of supernatural beings. The source describes Sekien’s Dorotabo as a creature he likely created through metaphor and wordplay. During the Shōwa period, it appeared frequently in yokai manga and children’s books, becoming a relatively familiar figure in Japanese supernatural folklore.

The mud-covered humanoid in the modern ghost story resembles Sekien’s yokai, which likely explains why the name Dorotabo was applied to it. The two accounts belong to different contexts: one concerns a yokai associated with rice fields and artistic representations of supernatural creatures, while the other describes a frightening apparition haunting an office building at night. In both, the name evokes a muddy, uncanny presence, but the modern story particularly emphasises its foul smell, disturbing physical nature, and ability to vanish without a trace.

Zashiki-warashi

by

Tradition: Japanese Mythology
Alternative Names: Zashiki bokko, Zashiki-warashi
Category: House dweller

The Myth

Zashiki-warashi are childlike supernatural beings in Japanese folklore, especially associated with Iwate Prefecture and the Tōhoku region of northeastern Japan. They inhabit traditional homes, particularly parlors and storage rooms, where they perform mischievous pranks. Although their appearance is not described in detail in every account, they are understood as spirits that take the form of children. Their presence is often considered a sign of good fortune, and families believed to host one could become prosperous and wealthy.

These spirits are not always seen directly. Their activities may be noticed through disturbances inside the house, and some traditions describe them moving around the edges of homes on rainy days, frightening visitors. Related beings include the notabariko, which peeks out from the inner dirt-floored room and crawls around, and the usu-tsuki warashi, which makes noises with a stone mortar. These figures are regarded as related, lower-ranking forms of the zashiki-warashi.

The presence of a zashiki-warashi is traditionally associated with the prosperity of a household. In the Tōno Monogatari, a collection of Japanese folktales recorded by Kunio Yanagita, it is said that families in whose homes these spirits dwell become prosperous. Their appearance in a house can therefore be interpreted as a sign that the family’s fortunes will improve. Conversely, stories connect the departure or loss of supernatural protection with a household’s decline, making the spirits important figures in explanations of changing fortunes within village communities.

Some darker traditions connect zashiki-warashi with the spirits of children who died through infanticide. In parts of the Tōhoku region, accounts describe unwanted children being killed and buried in the dirt-floored rooms or kitchens of homes. The spirits of these children were said to wander around houses, particularly on rainy days, frightening visitors. These traditions offer a more tragic explanation for the spirits’ childlike appearance and their association with old family homes.

Other stories suggest that zashiki-warashi may be connected to curses involving carpenters and tatami makers, or that they are related to kappa, supernatural beings associated with water. In some accounts, a kappa leaves the depths and enters a nearby house to play pranks before settling there. Their childlike form has also been linked to religious beliefs in which children serve as intermediaries between the human and divine worlds, resembling protective child-shaped figures in Buddhism.

Zashiki-warashi therefore occupy an ambiguous place in Japanese folklore. They can be playful household tricksters, protective spirits, or reminders of darker histories hidden within traditional homes. Above all, they are closely associated with family prosperity and the belief that the presence of an unseen supernatural being can influence the fortunes of an entire household.

Chopirako

by

Tradition / Region: Japanese Mythology
Alternate Names: —
Category: Gnome

The Myth

The Chopirako is said to be the most beautiful and refined of the household spirits known as zashiki-warashi. It appears as a small child, no more than four or five years old, pale and strikingly white, with a presence gentler and more radiant than its kin. Where a chopirako dwells, the house is blessed with quiet prosperity and harmony.

In old stories from northern Japan, a single household might host several such child spirits, each bound to a different space. One might live in the earthen floor, another in the living room, another near the tools of daily labor. The chopirako, however, was the highest and most graceful among them, associated with the heart of the home rather than its margins.

At night, when the house slept, these spirits made themselves known through sound rather than sight. Soft footsteps, the whisper of movement, or the faint presence of a child passing unseen through rooms were signs that the spirits were awake. They were never meant to be watched directly, and attempts to spy on them risked driving them away forever.

As with all zashiki-warashi, the chopirako was a double-edged blessing. As long as it remained, the household would thrive. If it vanished—offended, neglected, or simply choosing to depart—fortune would fade, and the house would fall into decline. Thus families treated their homes with care and respect, believing that unseen children might be listening, watching, and quietly deciding the fate of those who lived there.

Azuki Hakari

by

Tradition / Region: Japanese Mythology
Alternate Names: Azukihakari, Bean Counter
Category: House Dweller

The Myth

In the quiet hours after midnight, when houses settle and the world grows still, the Azuki Hakari makes itself known—not by sight, but by sound.

It is said to dwell in rural homes, temples, and old buildings, hiding in attics, ceilings, or garden shadows. No one has ever seen an Azuki Hakari. Its presence is announced only through a sequence of noises that unfold with deliberate precision, as though following a ritual known only to the spirit itself.

An encounter often begins with heavy footsteps above the room, pacing slowly in the narrow space between ceiling and roof. The steps are deliberate, neither hurried nor random, as if someone were measuring the house from above. Soon after, another sound joins the steps: the dry, rhythmic scattering of azuki beans, striking against windows or sliding doors. The sound repeats steadily, like counting—bean after bean—growing louder with time.

As the night deepens, the noises change. The dry patter of beans becomes the sound of splashing water, as though something unseen were washing or pouring liquid nearby. Finally, the rhythm resolves into the unmistakable clack of geta—wooden sandals—walking just outside the room, circling the house.

Those who dare to open the door or window in response are met with sudden silence. The footsteps vanish. The beans are gone. No water remains. There are no tracks, no marks, no sign that anything was ever there.

In older accounts, it is said that the Azuki Hakari may sometimes cause dust or scraps of paper to fall from the ceiling, but it never harms the residents. It does not steal, attack, or speak. Its purpose is unknown. It simply performs its nocturnal counting and departs.

Because the Azuki Hakari is never seen, its true nature remains uncertain. Some believe it is related to other azuki spirits, while others insist it is something separate—an invisible presence made entirely of sound. In many stories, encounters once attributed to river-dwelling azuki yōkai are now believed to have taken place within homes, pointing instead to the silent work of the bean counter.

Thus the Azuki Hakari endures in folklore as a reminder that not all spirits announce themselves with form or violence. Some are known only by rhythm and repetition, by footsteps in the dark and beans that were never there—proof that even an empty house is never truly empty.
