Traditional Yokai Encyclopedia

An interpretive version based on one plate from Toriyama Sekien’s Konjaku Hyakki Shūi. It depicts a blind lute-priest in tattered hakama and wooden clogs, staff in hand, traveling the roads on stormy nights. A marginal note mentions plucking the shamisen in brothels, reflecting ties between early modern urban pleasure quarters and performing guilds. Folklorically, it blends visual othering with social satire, presenting a visage of the age more than a tale of uncanny powers. Kenji Murakami notes the othered image of the nocturnal zatō, while Katsumi Tada reads a “demonic” aura of enforcement from their shogunal protection and involvement in finance. Neither grants concrete supernatural powers, emphasizing a presence that appears on rainy nights and overawes the heart.

Passed down around Edo’s Honjo district, the Okuri-Chochin is understood as a strange guiding fire that appears between safety and dread on night roads. Its light sways with a person’s steps and breath, keeps its distance while leading ahead, yet never allows touch. At times it slips to one’s rear or flank to upset direction, and when accompanied by a clapper-like sound it is recorded under the alias “Okuri Hyojiki.” The “Lantern Boy” of Ishihara Warigesui is a formless Odawara-lantern flame that circles on all sides and vanishes when approached, regarded as the same phenomenon as the Okuri-Chochin. In Mukojima it is called the “Okuri-Chochin Fire,” believed to light one’s footing and ensure safe passage, with cases linked to offerings at Ushijima Myojin. Though it rarely causes direct harm, it can lead travelers astray, so locals advise not to chase it, to keep a set distance and pass it by, or to bow at a shrine or temple to seek protection.

The core of Hachirotaro's story lies in 'transformation brought about by breaking a rule' and 'resurgence after defeat.' The minor taboo of hoarding three char invited an uncontrollable thirst, turning a human into a dragon. This karmic retribution has been passed down in the hunting and fishing culture of the Tōhoku region as a warning against monopolizing nature's bounty. Although Hachirotaro claimed Lake Towada as a dragon, he lost it in a struggle against Nansobō. Yet, he went on to carve out a new body of water, Hachirōgata, to rule. This narrative arc—where the vanquished becomes the sovereign of a new realm—binds the vast geography spanning the three lakes into a single epic. His union with Princess Tatsuko and his seasonal migrations offer a mythic explanation for the real natural phenomenon of Hachirōgata freezing while Lake Tazawa remains unfrozen. It reveals how the people interpreted the physical behavior of the lakes through the lens of a dragon god's romance.

An iconographic reading of the Hair Demon as depicted in Toriyama Sekien’s Hyakki Tsurezure Bukuro. A woman’s hair, infused with its owner’s passions, becomes autonomous, standing on end at midnight as its locks extend and contract like living things. Cutting it offers only brief respite, for it regrows and multiplies at once. Rooted in a dual folk view that both sanctifies and shuns hair, it is shown as a being where tsukumogami traits cross with vengeful-spirit nature. Its body is a mass of hair without face or limbs, asserting menace through motion and shifting length. Memorial offerings and proper hair-cutting rites are said to calm it, yet no certain banishment method is recorded.

Based on an old Awa record. Hair kept in a hemp bucket acts as part of the deity’s body or a manifestation of divine power, restraining anyone who disrupts shrine order. It is understood to activate within the shrine precincts rather than roaming independently. The core image is hair that quietly elongates, splits into strands, and entangles targets one by one, reacting to acts like defilement or theft rather than attacking onlookers indiscriminately. Shigeru Mizuki depicted it as a massive hair mass under the name “Asaokege,” but the actual tradition emphasizes function over appearance. Often read as a symbol of in-shrine norms encouraging observance of faith and taboos.

An amalgam of hair-cutting incidents reported from Edo and other early modern towns. At night, in the street or at the threshold of an indoor privy, there is a sudden brush of contact, and moments later the victim’s hair falls away still neatly tied, without their noticing. Witnesses describe a figure black from head to toe, catlike, or with the feel of velvet, yet its true form remains uncertain. Servant girls and maids were often noted as victims, with rumor-mongering and official crackdowns recorded side by side. Folklorically, taboos surrounding hair as part of the body overlap with notions of impurity tied to night roads and privies, casting an unseen assailant as a yokai. Its method and motive are never stated in tradition, placing it among urban horrors shaped by fear and unease.

The image of the Hakutaku varies across eras and texts. In the Sancai Tuhui and the Wakan Sansai Zue it appears as a white lion-like auspicious beast symbolizing lucid and orderly governance. Edo painter Toriyama Sekien employed multi-eyed motifs, adding an eye on the brow to heighten its power to perceive calamities, though older depictions sometimes show only two eyes. Prints of the Hakutaku served as apotropaic images posted on doors or carried as charms, invoked for protection during travel and epidemics. The design also appeared on imperial procession flags and on temple and shrine door panels as talismanic emblems of authority and sanctity, examples of which can be seen at the shrines and temples of Nikkō in Japan. The tradition is sometimes read as a personification of ethics and disaster lore, venerated as a being that classifies anomalies and teaches countermeasures.

Hakuzosu, disguised as a monk, is a particularly theatrical yokai even among tales of fox transformation. Foxes often transform into beautiful women, travelers, or close family members, but Hakuzosu chooses the form of a monk. That choice holds the power not only to reassure the other person but to move them with words. The old fox in Tsurigitsune disguises himself as the hunter's uncle and preaches on the sin of fox trapping. The persuasion succeeds to the point of making him throw away his traps, but the bait on the way home destroys that victory. Hakuzosu does not lose because he deceived a human. Because the fox, who spoke using human ethics, is ultimately pulled back into the fox's own hunger, he is comical, pitiful, and terrifying. This form does not render the yokai called a fox a simple villain. Hakuzosu is on the side whose clan was killed; he is an avenger, and a preacher. His words contain a protest against killing, while simultaneously containing deception through transformation. If Kuzunoha of Shinoda Forest is remembered as a fox mother unable to sever ties with humans, Hakuzosu is an old fox breaking down between human law and a fox's body. Both are stories of foxes entering human society, but while Kuzunoha is a story of love and parting, Hakuzosu is a story of eloquence, traps, desire, and exposure. The Hakuzosu of Tsurigitsune undergoes a double transformation on stage. The first transformation is within the story, where the fox transforms into the monk named Hakuzosu. The second transformation is in the actor's body, where the kyogen master adopts the fox's posture and movement, yet hides it beneath the behavior of a human monk. The struggle between intellect and instinct, pointed out as a key element of appreciation, appears not only in lines but in the way of walking, the way of looking back, and the spacing as he is drawn to the bait. Therefore, Hakuzosu is a yokai that is read as well as a yokai that is performed. The true identity of the fox is not exposed at the end; it becomes visible as the body gradually returns to a fox. On the other hand, the Hakuzosu of the Ehon Hyaku Monogatari lineage makes the monk-shaped fox look even darker as a ghost story accompanied by the place name of Kai Province. As seen in the National Diet Library bibliography, the book is a ghost story art collection written by Momosanji and illustrated by Takehara Shunsen, and late-Edo readers received this fox through a combination of pictures and captions. While the stage Hakuzosu returns to a fox through a momentary failure, the picture book Hakuzosu lurks long within human settlements. What becomes problematic here is not only how skillfully the fox transforms. It is how much people believe in the institutions of monk's robes, temples, and sermons. Hakuzosu exploits that form of trust. The white fur of the fox and the human status overlap in Hakuzosu's name and notation. The variant spellings Hakuzosu (白蔵主, 伯蔵主, 白蔵司, 伯蔵司) gently oscillate readings between the fox's white hair, a monk's name, and a fox disguised as a human. While the names of transforming foxes often remain attached to lands or people's names, in Hakuzosu's case, the very act of "the fox borrowing a name" becomes the core of the apparition. To give one's name is to acquire a role in society. By taking a monk's name, Hakuzosu enters the inside of the temple, enters the inside of the hunter's house, and finally returns to a fox in front of the audience. Placing Hakuzosu within the genealogy of foxes, he is not a great demon fox like the Nine-Tailed Fox or Tamamo-no-Mae that shakes royal authority. Nor is he a fox woman who leaves behind a child like Kuzunoha. Hakuzosu concentrates the point of contact between fox and human into "persuasion" and "traps." Humans catch foxes with traps, and foxes catch humans with words. Both are techniques reading the opponent's weakness, and those techniques succeed for just an instant. However, when the smell of bait, the desire for prey, and the logic of revenge overlap, the fox approaches his own trap. The reason the story of Hakuzosu has survived so long is that it depicts not a fox's cunning, but a weakness that is harder to escape the wiser one is. Hakuzosu on an encyclopedia acts as a keystone expanding fox-type yokai horizontally. If the Nine-Tailed Fox bears the nation and calamity, Kuzunoha parent and child and parting, and the wild fox possession and marginality, Hakuzosu connects performing arts and narrative, monk's form and fox's body. The fox is not a single mold; it can be a divine messenger, a mother, a calamity, or an actor. By placing Hakuzosu, an axis of "the performed fox" is established within the vast yokai group called foxes.

An interpretation aligned with Toriyama Sekien’s imagery and accompanying text. Only a white feminine hand emerges from the sleeve opening, while the absent owner is signified by the garment itself as the main subject. The kosode was a fine everyday robe of the time; whether it became a keepsake, was dedicated to a temple, or sold marks the branching fate, with spiritual disturbance manifesting as attachment residing in the clothing. It layers commentary on courtesans’ circumstances and the irony of buyout money with an aesthetic for dress and a sense of impermanence, functioning less as a concrete monster than as a “visible metaphor.” In folktales, illness after acquiring secondhand clothes and nightly apparitions of a white hand often cease once the robe is offered to a temple and sutras are chanted. Situated at the crossroads of possessed objects and ghost lore, it can be read as tsukumogami, yet its focus remains the emotions of the garment’s former owner.

An interpretation grounded in the imagery found in Sekien’s Gazu Hyakki Yagyō and night-parade picture scrolls from the Tenpō era onward. It is depicted as a shaven-headed figure like a blind monk, with large eyeballs set in both palms, standing in a moonlit wasteland. Narrative explanations are sparse, but linked to the illustration and tale in Shokoku Hyaku Monogatari, it is assumed to locate targets in darkness with the eyes in its hands and to sniff out those who have fled and hidden. In collected folklore it sometimes connects to vengeful spirits of the blind, and is often read as a symbol of exchanged sight and touch, witnessing and exposure. Etymological wordplay has been suggested (raising a hand-eye, bald monk), but none is definitive.

White Hannya names a coloration and stage use of a Noh mask; it is not another name for Lady Rokujo herself. The National Theatre explains that Aoi no Ue uses the highest-ranking White Hannya for Lady Rokujo, the high-born shite in the latter half of the play. In the play, Lady Rokujo's living spirit appears in a Hannya mask after taking on a demonic aspect, and an ascetic's spiritual power eases her heart. The two horns, gold-colored eyes, and fangs convey rage, while the inverted-V upper eyelids and disordered hair strokes preserve sorrow. White Hannya is a mask that catches the moment when a noblewoman's humiliation, loneliness, and clinging love take on a demonic aspect without losing dignity or pathos.

It is not a half-human, half-yokai, but rather a "half-god, half-beast" monster whose core is a highly realistic slaying tale recorded in the Mimasaka topography *Sakuyo-shi*. The biological Japanese giant salamander is an actual Special Natural Monument inhabiting the Asahi River system; its bizarre appearance and longevity sparked the imaginative belief that it was immortal and "wouldn't die even if torn in half." Its gigantified form was feared as the master of Ryuzu no Fuchi. The causal chain wherein the slain creature's curse wiped out the Mitsui family speaks of the beast's grudge destroying even the victorious slayer, ultimately only quieted by enshrinement. It possesses a rare structure combining a monster-slaying tale, a curse tale, a deification tale, and a festival origin. At the Hanzaki Center in Yubara Onsen, live giant salamanders are still protected and exhibited today, making it a land where legend and reality exist side-by-side.

When viewing the Hari-onna as the "hook-haired woman of the Uwajima night roads," the fear of this yokai is not just that "her hair becomes a weapon." What appears first is the form of a beautiful woman; she does not threaten her victim from afar, but builds a connection by offering a smile. When smiled at by a stranger on a dark road, a person might smile back as a greeting. The Hari-onna takes that small response as a signal to undo her hair and expose the hooks. The anomaly only begins to move after waiting for the victim's reaction. The design of having fishhook-like barbs at the ends of her hair is so clear that it practically explains the name Hari-onna (Needle Woman). Needles are for piercing, but here they function at the tips of her hair to snag. They are not blades for cutting, but hooks for entangling those who flee. Disheveled hair is a sign of disorder and terror, and at the same time, it is the reversal of a beautiful woman's hair instantly changing into a capturing tool. Even though her hair was seen as part of her face and adornment, the moment she draws near, it becomes external hands that seize the victim's body. Treating the location in detail, the Hari-onna can be read as a yokai of the night roads in the Uwajima region, southern Ehime Prefecture. The official explanation on Mizuki Shigeru Road lists the location as the Uwajima region, Ehime Prefecture, and general summaries also append the name of Sakuraoka in the former Johen Town. However, the Hari-onna is not a yokai fixed to a specific shrine or ancient battlefield. Her location is the living sphere of the "Uwajima region," and her scene is the night road. Therefore, it is best to place the Uwajima region as the main axis on the map, and explain the details in the text. Rather than forcing a pin into an unverified point, positioning her as a mystery encountered on the roads of Nanyo fits this yokai better. When speaking of the Hari-onna, one cannot avoid the overlap with the Nure-onago. The Nure-onago is also known as a female yokai who smiles at people and stalks those who respond. Kenji Murakami states that because the traits of the Hari-onna are common with the Nure-onago of the Uwajima region, it is possible that Shigeru Mizuki emphasized the traits of the Nure-onago to create the "Hari-onna." This observation does not diminish the value of the Hari-onna. Rather, it is a prime example showing how a yokai is renamed and visually sharpened within an illustrated encyclopedia. If the Nure-onago is a yokai of smiles and obsession, the Hari-onna is a yokai given a memorable form in a single stroke with her "hooked hair." Comparing her to similar yokai makes the Hari-onna's position easy to see. The Iso-onna is spoken of as a female yokai who attacks people with her hair on the beach, and the Nure-onna is tied to the waterside and the grotesque form of a snake's body. The Kuchisake-onna creates modern urban horror through a question and facial reversal. The Ohaguro-bettari reveals a faceless visage with blackened teeth from beneath beautiful attire. The Hari-onna sits somewhere in between; she does not tear her face itself, but transforms her hair. She does not carry the strong presence of the sea like waterside female monsters, nor is she as modern as urban legends. She is a yokai who stands on the night roads of Nanyo with nothing but a smile and her hair. For this reason, keeping her description free from excessive added abilities makes it stronger. Explanations of her sucking massive amounts of blood, devouring souls, or flying around cities might be possible as later creative works, but they are not the core directly supported by the materials. Her solid outline consists of a woman's appearance, a smile, hooked hair, snagging and dragging men away, and the location of the Uwajima region. With smaller yokai, keeping this outline intact retains their scariness. The Hari-onna is a brief, sharp female yokai who makes victims realize—in the instant they return a friendly expression on a night road—that their expression was the very signal for her to capture them.

An integrated portrayal of Hashihime as a local divinity of Uji Bridge on the Uji River and as the jealous demon-woman of medieval war tales and Noh. As a local deity she was venerated at the bridgehead as a water and land guardian, protecting crossings and safe passage. Traditions forbid praising other regions or singing lines that stir jealousy upon the bridge, reflecting the belief that local gods dislike talk that exalts elsewhere. In the later tale, a woman visits Kifune, undergoes purificatory austerities in the Uji River, becomes a demon, and encounters a warrior at Ichijō Modori-bashi. Toriyama Sekien noted the shrine at Uji Bridge, and the Noh play Kanawa fixed the image of a demon-woman crowned with an iron trivet. Folklorically, bridges are liminal spaces, linked to water deities, female divinities, and warnings against jealousy, so ritual and storytelling long coexisted. While invented details vary by source, devotion to Uji Bridge, the Modori-bashi encounter, and the dual nature of taboo and protection form the core.

A version based on the conceptual monster Toriyama Sekien presented through painting and notes. Resentment dwelling in a cloth takes serpentine form and wanders in search of its master, merging the symbolism of tool-spirits and snakes. As folklore data, independent oral accounts are scarce, so it remains a pictorial taxonomy that links tsukumogami tales with legends of loom sounds heard near water. Etymological notes mention associations with the performance term “nijūhiro” and wordplay, but firm sources are limited. Visually, a long bolt of cloth writhes into a snake shape, its tip commonly rendered like a tongue or a slit.

Amakudari-Onna is recorded in Amami Ōshima as a variant of celestial maiden tales, emphasizing the visiting woman who steals human souls. She may appear even under clear skies with a light drizzle, marked by unusual attire carrying a white furoshiki. Her targets are mainly young men; she approaches with smiles and sensual allure, and if they comply, she takes their life or soul. A ladle of water serves as the medium, with taboos warning that drinking it lets her carry victims to the heavens. Folk defenses include staring her down and observing proper drinking etiquette, tying the tale not only to the uncanny but also to admonitions against nighttime wandering, illicit affairs, and improper hosting. Names vary—Amagari-onna, Amore-onna, Hagoromo beauty—reflecting regional shifts, yet the core remains consistent: a woman descending from heaven, fine rain, seduction, soul theft. Though mingled with later hagoromo legends, it strongly retains the imprint of Amami’s visiting-deity beliefs.

An interpretation grounded in Toriyama Sekien’s examples and Muromachi picture scrolls, taking the aberrant figure bearing a gohei as its standard. The paper-streamer wand signals ritual purity, yet Henroku brandishes it as an emblem of turmoil. It is not tied to any specific land or person, and is understood as an allegorical presence that appears where festivals or shrine order falter. Later traditions sometimes read it as a tsukumogami inhabiting the gohei, but firsthand accounts are scarce, and it is discussed chiefly within the lineage of visual iconography.

Rather than a specific singular *yokai*, *Hichigee* is a concept that collectively refers to the time, the phenomenon, and the divine spirit itself when 'gods come to the island at the change of seasons'. In the Tokara calendar, there are several turning points in a year, and on those nights, the boundary between the human realm and the divine realm was said to thin, and the gods would silently tour the island. The reason people refrained from going out, lowered their voices, and purified fire and doorways was to avoid hindering the unseen visitors and to prevent impurities from being brought in. On Akusekijima, this time of awe took the form of a masked god, surviving to this day as *Boze* appearing on Bon nights. While *Boze* is a 'visible' visiting god with Livistona leaves and grotesque masks, *Hichigee* was originally an 'invisible' god to be feared, situated in the oldest geological layer of the Tokara visiting god beliefs. The duality of entertaining while fearing the gods, and the structure of ancestral spirits (*Shichito Shogatsu*) and gods (*Hichigee*) visiting the island alternately, resonates deeply with the maritime worldview of the otherworld found in the southern islands.

An interpretation based on Toriyama Sekien’s Konjaku Hyakki Shūi entry “Kakurezato” (Hidden Village). The mouse and koban coins at the lower right recall tales in which subterranean mice carry wealth (the so‑called Nezumi Jōdo legend), hinting at ties between the village and chthonic or underworld realms. The shop curtain reads “Kakurezato,” expressing a boundary that opens suddenly as an extension of the everyday. The Hidden Village is not a single yokai but a boundary acting as if it has will, repeating wayfinding confusion, temporal slippage, the granting of fortune, and cycles of manifestation and disappearance. Outcomes swing with a visitor’s conduct and greed, from generous hospitality to wealth turning into leaf-litter, resonating with mountain otherworld tales and views of the beyond.

This version frames the Hidden Zato as a blind minstrel-yokai lurking in the mountains and caverns of Tohoku and Kanto. At midnight it pounds out sounds like a foot-operated mortar or rapid rice polishing, yet the source stays unseen and household tools are said to be “borrowed.” In some tales, peeking reveals the noise coming from a neighbor’s house. Some regions call it a child-snatcher, while others give it a benevolent face as a dispenser of mochi or treasure to the honest, making them prosperous. From early modern times, the idea of hidden villages merged with a mystique around blind guilds, recasting it as an unseen people dwelling in caves. Modern folk explanations liken the racket to insect wingbeats, but as a bearer of the uncanny it endures as a spirit in the form of a zato.

Rather than a concrete monster, the Hienma is a name that visualizes ruin born of lust. It belongs to the lineage of religious admonitions found in early modern yomihon and kaidan, and is often depicted in two aspects, bodhisattva-like and yaksha-like. More than appearing directly before a person, the original usage names incidents in which demonic hindrance intrudes upon human bonds. Later ages sometimes conflated it with vampiric or life-draining femme fatales, but in classical sources the moral lesson is central, and few fixed tales tie it to specific places or persons. Here it is framed within the classical scope as a symbolic presence that triggers a chain of temptation, delusion, and the decline of household fortunes.

A depiction of the hihi based on Edo-period images and folklore. Said to dwell in mountains, it is an aged monkey transformed into a giant, powerfully built being. Many regions tell that it bursts into loud laughter, and when its long upturned lips roll back to cover its eyes, it leaves an opening to strike. Tales include the abduction of women, bouts with woodcutters, and raising wind and storm to hurl people. Natural history compendia such as Wakan Sansai Zue report black hair, large size, and hearsay of human speech, though exact locales and physical evidence remain uncertain. Its name is commonly linked to its laugh. It is sometimes conflated with yama-warawa or monkey deities, but is often distinguished as an ape-shaped mountain monster.

The key to reading Hiko-san Buzenbō lies in Hikosan—the vast sacred site that is one of the three great centers of Shugendō in Japan—and in the tengu's character of two faces, reward and punishment. The history of Hikosan Shugendō issues from the Nara-period monk Hōren. Taking as founder this monk, whom the Shoku Nihongi records as having been granted forty chō of field in Buzen Province in the third year of Taihō (703), Hikosan grew into a great center of Shugendō ranking with the Dewa Sanzan and Ōmine. The name of Buzenbō appears with certainty in the Kamakura-period engi the Hikosan Ruki (1213). This work likens the forty-nine grottoes bored into the peaks of Hikosan to Miroku's Tosotsu Heaven and made the eighteenth the "Buzen-kutsu," the seat of Buzenbō. This very system of grottoes is the matrix of the faith in Buzenbō as chief of the tengu of Kyūshū. The Edo-period scale of the "Three Thousand Eight Hundred Bō of Hikosan" tells of this sacred site's prosperity. What characterizes the tengu Buzenbō is the sternness of his reward and punishment. As the history of Takasumi Shrine transmits, upon those of greedy and evil heart he carries off children and sets fire to houses in chastisement. Conversely, the wishes of the upright and deeply devout he hears and grants, and them he guards. These two faces of reward and punishment symbolize, as a tengu's judgment, the strict precepts that a Shugendō mountain imposes and the grace shown to those who keep them. The dread of a child-snatching tengu and the faith of parents praying for their children's safety were the front and back of one and the same Buzenbō. The separation of Shintō and Buddhism in the first year of Meiji and the prohibition of Shugendō in Meiji 5 (1872) scattered the yamabushi of Hikosan and dismantled the world of the three thousand eight hundred bō. The institution of Shugendō was lost, but the tengu faith of Buzenbō lives on at Takasumi Shrine; chanted in the Muromachi Noh play Kurama Tengu and standing among the forty-eight tengu of the Tengu-kyō as the great tengu of Kyūshū, he is still feared as one who sits upon the peak of Hikosan. Chigiri Kōsai of tengu scholarship, too, placed him within the system of the great tengu of the many mountains.

A reference edition compiled from the illustration and note in Toriyama Sekien’s Konjaku Hyakki Shūi. From beneath the floorboards extends the gaunt upper body of a nyūdō, lips slick, tongue reaching toward the saucer of an andon lamp. Its core origin is a didactic reading: the spirit of one who shirked labor appears nightly to lick the lamp oil, weakening the flame and hindering brushwork and needlework. The name connects to the letter-picture pun “Hemamushiyo Nyūdō,” suggesting a background in doodle play. In lived experience it overlaps with oil-loving bugs seen around hearths and kitchens, told as a being lured by darkness and the smell of oil. It causes no grave harm, preferring to make the flame waver, dampen the wick, and sap one’s focus. When spotted and scolded it shrinks back, a creature strongly inclined to hide in the shadows.
