Yokai Encyclopedia

In this version, we read the Jinmenken as a "road urban legend" born from the city during the late Showa era. The Jinmenken is not a yokai that appears fully formed in classical texts; rather, it is an entity where the rumor ran ahead, and magazines and television later gave it a contour. Because of this, its details are never fixed. Where it was seen, what it said, and whose face it resembled shift depending on the teller, and this malleability served as the fuel for its popularity. The stage of the "road" underpins the eeriness of the Jinmenken. On a night road, animal carcasses, lost dogs, the optical illusions of headlights, and suddenly crossing shadows are everyday occurrences. When an easily recognizable component like a "human face" is mixed in, the witness feels that "perhaps it wasn't a dog." The speed of vehicular society robs people of the time to verify. Passing by without being able to confirm whether it was a misperception or an anomaly strengthens the rumor. The Jinmenken's dialogue elevates this anomaly from a mere composite animal to an urban legend. Words like "Leave me alone" or "What are you looking at?" are closer to rejection than horror. The monster is not attacking; it hates your gaze. This sensation closely resembles the awkwardness of witnessing someone's bizarre behavior on a city street. The one who sees the yokai is slightly blamed as the rude interloper. In the realm of modern folktales handled by Miyoko Matsutani, modern vehicles and urban infrastructure become the sources of new ghost stories. The Jinmenken is positioned perfectly within this current. Instead of emerging from the old natural environment like fox-fire or a mountain witch, it appears from late-night stores, national highways, housing complexes, and the roads home from school. This dog clearly demonstrates how the stage of yokai has shifted in accordance with changes in lifestyle. This version of the Jinmenken is a yokai of incomplete transformation. The dog did not turn into a person; it remains a dog but merely possesses a human face. That incompleteness becomes both a joke and a nightmare. Children found it amusing as a rumor, and adults consumed it as a media phenomenon, but at the bottom of it all lies the lingering anxiety that "somewhere in the city, you might encounter something that cannot be classified." The Jinmenken is the form of that anxiety running at its lightest and fastest. Through the media, this version of the Jinmenken became a monster that "everyone knows, even though no one has seen it." Most people have never actually encountered it. Even so, anyone can instantly imagine the scene of a dog with a human face speaking. The rumor distributes the image before the sighting, and that image in turn generates new eyewitness accounts. The choice of a "dog" is also sharp. A dog is close to the human sphere of living, considered a loyal and familiar animal. When a human face is pasted onto it, that familiarity is shattered instantly. If it were a complete monster, you could keep your distance; but because it is a dog, you momentarily approach it. That delay establishes the ghost story of the Jinmenken. The Jinmenken also carries the burden of urban loneliness. Even though it can speak human language, it doesn't seek conversation; instead, it rejects it with "Leave me alone." This is remarkably similar to the sensation of city life, where people are densely packed yet do not interact with one another. The anomaly doesn't attack humans, but finds the very gaze of humans to be a nuisance. Within that lies its coldness as a modern yokai.

Jorōgumo is formed where a living spider name, early modern woman-spider tales, Sekien’s woman-with-spider-legs image, and spider-pool stories overlap. In *Tonoigusa*, a mother and child lead to a large spider above a ceiling; in *Taihei Hyaku Monogatari*, a marriage-seeking girl’s illusion leads to a small spider below the eaves. At the water’s edge, thread catches a person and can pull a tree into a pool. The popular biwa seductress who eats men does not appear whole in any single confirmed classical source.

A one-legged goat *majimun* that haunts the Ganguri-yumata intersection in Shimozato. Standing on its solitary hind leg, it glides out of the darkness into deserted crossroads, its hard hooves ringing out with a rhythmic "gan, guri-guri" sound. Once it spots a passerby, it unleashes an ear-splitting shriek that tears through the night and leaps over their head like an arrow, snatching their *mabui* (soul) in the process. However, it cannot harm those who quickly crouch down to avoid being jumped over; defeated, it leaves only its scream and footsteps echoing in the street before melting back into the shadows.

A rendition based on records and oral tales of the shape-shifting otter. It mimics human speech, but its intonation and sentence endings sound off, and when pressed with questions it gives nonsensical replies. Its guises range from a beautiful woman to a child or a monk, distracting passersby and misleading them with tricks such as snuffing lanterns, inviting people to wrestle, or making stones and tree roots appear human. In some regions it overlaps with kappa lore, possessing great strength in water and luring victims to look upward to gain advantage. In the context of spirit possession, it is feared for sapping a person’s vitality and inducing lethargy. While violent episodes are recorded, most encounters amount to threats or pranks.

This version digs into the role the Kiko plays among the four fox ranks: that of a boundary. The fox hierarchy is not merely an order of strength but a single ladder by which the beast draws step by step closer to spirit and to god. The rung on which the Kiko stands is the very seam dividing “the flesh-bodied Yako” from “the form-shedding Kūko and Tenko”. Where the Yako is known for visible mischief — leading travelers astray, taking on a guise to fool them — the Kiko, having already slipped free of its shell, turns its workings further inward: possessing a person, troubling the heart. The view that the fox in tales of possession is no ordinary Yako but a Kiko of deeper attainment is rooted right here. There is one more thing visible in the Kiko: incompleteness. Where the Kūko holds twice its power and goes on to become the Tenko and depart the human world, the Kiko cannot yet cut its ties to people. Swaying between the instinct of the beast and the detachment of a god, deceiving and possessing by turns, it is in a sense a fox still only halfway through its training. If the higher foxes are beings that watch quietly over the world, the Kiko is the one that, nearest of all to humankind, still struggles on.

This is Kincho, the guardian deity of Yamatoya and the tanuki commander of Hikaino. Originally a highly loyal tanuki saved by Moemon, he strove to bring prosperity to the dye shop in return for his life. He later went to train under Rokuemon, the supreme commander of Shikoku's tanuki, but despite his extraordinary talents being recognized, he incurred Rokuemon's wrath by refusing a marriage proposal. After his friend was murdered, Kincho led the Hikaino tanuki army in the epic three-day "Awa Tanuki War" against Rokuemon. Though he ultimately vanquished his arch-nemesis in a one-on-one duel, he too succumbed to his wounds. Revered in death as Kincho Myojin, his name lives on today as a god of business prosperity and victory.

A curated version of a mountain anomaly told among matagi hunters in northern Akita, framed within hunting rites and taboos. It looks like a dormouse or tiny field mouse, round, small, and quick. When it faces a person, it suddenly swells and unleashes a single blast like a gunshot. In many accounts it bursts apart, scattering flesh and viscera, while other tellings say it only bounces about and booms without exploding. Either way, an encounter is a dire sign of the mountain god’s anger or warning, and hunts were to be halted after a sighting. To continue was feared to bring empty bags, bad weather, or avalanches. To avert the curse one should descend the mountain and purify oneself at home by chanting “Namu Aburaunken Sowaka.” As for origins, one tale says seven matagi of the Kodama school were punished and became Kodamanezumi, while another reads the legend as a taboo memory arising from digging up hibernating dormice. Dates and sources are uncertain, with most accounts preserved orally.

In this version, we read the Kuda-gitsune as the "commanded fox lurking in a bamboo tube." The smallness of the Kuda-gitsune is not just its appearance. Because it is small enough to fit in a tube, it can be carried around. Because it can hide under the floorboards or in the storage room, it becomes a family secret. Because it is out of public sight, the rumors that "it possessed another family," "it called in wealth," or "it sent an illness" can take hold. Being small is precisely its power to slip into the cracks of society. The premise of a commanded fox spirit distances the Kuda-gitsune from the Inari fox. While Inari foxes are often enshrined as divine messengers, the Kuda-gitsune is spoken of as a tool carrying human desire. While moving on its master's orders, it simultaneously affixes the reputation of a "possessed lineage" (tsukimono-suji) to that master's household. The power to bring profit is also the power to invite suspicion. The more the Kuda-gitsune fulfills human wishes, the murkier it makes human relationships. The Kuda-gitsune as an explanation for illness is folklorically significant. When unknown diseases, sudden madness, or abnormal appetites occurred, it was sometimes said that a fox had possessed the person. This is an explanation from an era outside modern medicine, but simultaneously the language expressing tension between households. The questions of "Who sent it?" and "Which family has the fox?" drag not only the sick person but the entire community into the fray. The relationship with Izuna magic strengthens the sorcerous nature of the Kuda-gitsune. In the belief spheres of Izuna Gongen and fox users, the imagination of commanding tiny fox spirits overlapped with mountain asceticism and magical power. Here, the Kuda-gitsune is not a wild fox, but a spiritual familiar placed under a practitioner's management. The container of the bamboo tube symbolizes this dominant relationship. Foxes are confined, carried, and dispatched to wherever necessary. The Kuda-gitsune in this version is not a cute little fox, but a fox serving as a family secret. Though its form is small, its impact is immense. Wealth, illness, marriage, reputation, and prayers revolve around a single fox spirit. Therefore, when reading the Kuda-gitsune, we must look at it not just as an animal yokai, but as a mechanism through which village society named invisible imbalances. The tube of the Kuda-gitsune is a symbol of domination. The imagination of shrinking a spirit, putting it in a container, and taking it out when needed perfectly expresses the human desire to possess invisible power. However, the spirit that was supposed to be possessed eventually turns the household itself into an object of suspicion. The Kuda-gitsune brings profit to its user while eating away at their reputation. In this version, we also read the Kuda-gitsune as the "reverse side of wealth." When there is wealth that cannot be explained by effort or luck, people imagine a secret spirit behind it. Tales of foxes carrying wealth are words mixed with envy and caution. Families possessing them are envied and shunned at the same time. The Kuda-gitsune brings profit and isolation together. Furthermore, the Kuda-gitsune is a spirit at exceptionally close range, even among foxes. It is not encountered in the wild mountains, but resides under the floorboards of the house or inside a tube. It is not in a distant otherworld, but lurking in the storage spaces of daily life. This proximity is the creepiness of the Kuda-gitsune. Because it is small, it is overlooked, and because it is overlooked, it can slip in anywhere. Reading the Kuda-gitsune is also reading what it means to "possess a fox." Holding a spirit might bring profit, but from that moment, the owner is also possessed by the spirit. The Kuda-gitsune shows that the more people desire secret power, the more they are bound by that secret.

Kuzunoha of Shinoda Forest is an entity that transforms a fox's shapeshifting tale into a mother's story. Stories of foxes transforming into human women exist everywhere, but in Kuzunoha's case, seduction or mischief is not placed at the center. The rescued fox becomes a human wife as a repayment of kindness, gives birth to a child, and eventually returns to the forest upon having her identity discovered. While maintaining the ancient mold of an inter-species marriage, this plot connects the spiritual power of a fox and a human lineage into a single tragic family history by connecting it to the birth tale of the famous onmyoji, Abe no Seimei. The stage of the story is the Shinoda Forest. The white fox saved by Yasuna takes the form of Kuzunoha, they become husband and wife, and raise Dojimaru. However, a fox that has entered the human world cannot live in that form forever. When her true identity is exposed, Kuzunoha cannot continue to hold her child as a mother, nor can she discard her return to the forest as a fox; she cannot abandon either. In that torn moment, she leaves a farewell poem written on a sliding door (shoji). While indicating her whereabouts, the poem simultaneously implies that even if he goes there, a complete reunion will not be fulfilled. The forest of Shinoda is a place of homecoming, but at the same time, it becomes a place to pursue the mother lost from the human home. Ashiya Doman Ouchi Kagami turned this tale of a fox mother into a strong memory of the stage. The National Theatre performance script found in the NDL Search indicates that the "Kuzunoha scene" has been treated as subject matter for Kabuki appreciation classes even in modern times. The subtitle "Shinoda-zuma Urami Kuzunoha" in the Meiji-era publication pushes the sorrow of Shinoda's wife to the forefront right from the title stage. While Kuzunoha is often explained as "Seimei's mother," on stage she should rather be seen as a woman who leaves her name and departs, a fox whose true identity is known, an otherworldly being who cannot sever the fact that she is a mother. In iconography, Kuzunoha is remembered by the scene of parting with her child. Ashiya Doman Ouchi Kagami: Abe Yasuna, Kuzunoha, and Yokanpei by Toyohara Kunichika in the Izumi City Digital Archive is registered as an actor print depicting the performance at the Ichimura-za in 1865, conveying that Kuzunoha was firmly established in the visual culture of the stage. What is important here is the tension of the "fox mother in human form" played by the actor, rather than the figure of the fox itself. The audience views the parting as the sorrow of a human mother and child, even while knowing she is a fox. It is the moment when a yokai stands at the center of a human drama, and Kuzunoha's charm lies in this duality. The fox's power acts as inheritance rather than attack in Kuzunoha. The child she bears, Dojimaru, is later spoken of as Abe no Seimei. The explanation that Seimei possesses supernatural talent because he carries the blood of a fox is the logic of legend, not history. However, this logic functions to reconnect the onmyoji's spiritual authority back to the natural and otherworldly realms. Seimei's extraordinary abilities are supported not only by courtly knowledge but also by the power of his mother from the forest. There, Kuzunoha becomes a mediator passing the fox's demonic power to human society. Simultaneously, Kuzunoha restrains the dangerous allure often found in fox legends. While Tamamo-no-Mae and the Nine-Tailed Fox are spoken of as entities that disrupt the court, Kuzunoha does not destroy the home; she departs after establishing it. That is why it is sad. When her true identity is revealed, the story does not proceed in the direction of "exterminating the monster." She is depicted not as an enemy to be vanquished, but as a mother who must return. This distinction makes Kuzunoha uniquely special within the genealogy of fox yokai. The significance of reading Kuzunoha in an encyclopedia is to confirm that yokai are not made solely of terror. She is a fox, a wife, a mother, a famous scene on stage, and a geographic memory in Izumi. The figure returning to the Shinoda Forest is the moment the life that briefly opened between yokai and human closes. What remains there is not the eeriness of a supernatural entity whose true form was exposed, but the very process by which affection crossing boundaries is carved long into the land and performing arts. This figure can be read especially as the "mother who leaves her name" among tales of fox wives. Kuzunoha does not merely depart; she points the way to Shinoda Forest through her poem, carving her origins into her child's memory. In the sense that the mother's disappearance directly becomes the beginning of the Seimei legend, she is never a supporting character in the story, but the very entrance bringing spiritual authority from the Otherworld.

This version looks a little more closely at what kind of being the Kūko actually is. In the Edo-period ranking of foxes, only the lowest, the Yako, was thought to possess a visible body of flesh; from the Kiko upward, foxes were believed to become formless spiritual beings. Because the Kūko ranks just below the Tenko, its shape as an ordinary beast has lost almost all meaning, and it manifests instead as a presence or an influence. By its very nature it differs from the Yako, which stands before people’s eyes to deceive them. A high-ranking fox is closer to one that protects and guides than to one that harms. Overlapping with the lineage of white foxes regarded as messengers of Inari, the Kūko and Tenko were revered in the world of belief as wise foxes that serve the gods. The reason the Kūko so rarely causes any concrete incident is not weakness but that it has long since outgrown the stage of meddling with people out of vanity. Even so, because it wields immense supernatural power, it was thought that to slight it might invite calamity. Gentle toward those who revere it, showing a glimpse of its power only before the arrogant, the Kūko has been spoken of as a mature fox that knows exactly the right distance to keep from human beings.

A classic example of illusion craft attributed to the tanuki of Awa. It presents indoor furnishings incongruously outdoors and compels the target to keep “lifting” or “peeking,” eroding their sense of direction and time. The number thirty-six is sometimes linked to shugendō numerology, but local tales give no strict rationale, instead advising a practical countermeasure: stay calm and brace the belly. It causes no harm, and at dawn the spell breaks and the path appears as if nothing happened.

Myobu is the deified form of the white foxes serving as the familiars of Inari Okami, enshrined as "Myobu Tome-no-Kami" at Byakkosha, a subordinate shrine of Fushimi Inari Taisha. Unlike secular beliefs that worship foxes themselves as gods, the essence of Myobu lies in its reference to white foxes acting as divine messengers attending closely to the deity. "Myobu" is a title derived from the ranks of court ladies under the Ritsuryo system. Because they serve Inari Okami, who holds the Senior First Rank, the white foxes were likened to high-ranking court ladies of the imperial palace. The shrine building of Byakkosha, built during the Kan'ei era in the one-bay Kasuga-zukuri style with a cypress bark roof, is an Important Cultural Property. Initially called "Oku-no-Myobu" or "Myobusha," it is said in Harumitsu Harada's "Inari Jinja Engi" to enshrine Akomachi and Osusukiroku, originating from a court lady named Susumu Myobu. The statues of white foxes holding rice ears, scrolls, keys, and jewels in their mouths are an iconographic expression showing that Myobu is a pure divine messenger mediating the harvest of fields, words, storehouses, and treasures.

The form of a cat kept in a human home for many years, aging until its tail splits into two, thereby "ascending" to acquire the power to speak and manipulate ghostly flames. Discarding the "mountain beast" aspect spoken of for the species as a whole, this is an interpreted version that maximizes its nature as a "house yokai" (kayou) sharing living space with humans. In this version, the Nekomata is said to stand on its hind legs late at night, place a towel on its head, and dance wildly in the shadows of the hearth. This bizarre dance, originating from the depiction in Toriyama Sekien's "Gazu Hyakki Yagyo", added a somewhat comical and human-like charm to what was originally a terrifying monster cat legend. Furthermore, this Nekomata skillfully mimics the faces and voices of people to deceive family members. It often takes the form of an old woman, which is sometimes interpreted as a projection of the power and underlying intimidation of the matriarch who managed the household for years, superimposed onto the image of an old cat. The folklore presents a clear duality: if the homeowner treats the cat roughly or kills it unreasonably, it becomes a vindictive curse deity, setting ghostly fires (Nekomata fire) in the house and ruining the family lineage. On the other hand, a carefully cherished Nekomata uses its demonic powers to "protect the house." As depicted in works like Sawaki Suushi's "Hyakkai Zukan", there are benevolent tales of them shapeshifting into a shamisen-playing geisha to save a benefactor in a crisis, or using their demonic fire to intimidate and burn away other evil spirits or diseases (impurity) attempting to enter the home. To them, the split tail is not merely a sign of monstrosity; one tail serves as an antenna symbolizing "gratitude (or resentment) toward humans," and the other symbolizes "the demonic nature of a beast."

The Hearth-Guarding Old Nekomata is a version of a cat that has been kept in one place for many years, growing old by the hearth stained with soot and ash, until one night it suddenly manifests with a tail split in two. Positioned at the opposite extreme from the violent Nekomata that attacks humans in the mountains (as noted in texts like "Meigetsuki"), this being inhales the breath of the house and its generations of life, absorbing the spirit of fire and cooking smoke, and thus behaves much like a household deity (or Zashiki-warashi). While it is an extension of the folk belief that "a pet cat transforms" cited in "Tsurezuregusa", it carries a much more protective nature. Even without using human words, it signals by clinking the pot lid or drawing patterns in the ash. The pale ghostly fire (Nekomata fire) that darts in the corner of the parlor late at night is not a curse fire to be feared as in "Yamato Kaiiki", but is rather considered a purifying mark where this old Nekomata preemptively licks away the house's fire hazards and burns off evil energies. In some villages, it is believed that one tail connects "the lineage of the family" and the other "the divine spirit of fire," making the split not a mere deformity but a sacred sign holding dual duties. The Old Nekomata always draws near when the family gathers around a corpse. There is a common fear that cats resurrect the dead, often causing confusion with the Kasha (the monster cat depicted snatching corpses in works like "Gazu Hyakki Yagyo"). However, this version never causes a disturbance; it merely sniffs the ragged breath with its nose and lights a small spark to dispel lingering earthly attachments. Therefore, the proper etiquette is for the family not to brandish blades before the Nekomata, but instead to burn a single stick of incense as a "farewell fire." If a long-kept cat is treated roughly, the stove will burn empty in the dead of night, and overlapping wet footprints will appear on the walls. Conversely, in homes that mourn respectfully, folklore akin to the "urban legends" pointed out by Kunio Yanagita survives: on a snowy morning, only the space under the shoji is warm, and the shadows of mice vanish entirely from the rice bin. This version is sometimes spoken of as an old cat that once disappeared into the mountains returning out of longing for the house, or as an old indoor cat whose tail split naturally over time. The custom of cutting tails to prevent transformation (the origin of the bent-tail cat) also exists, but in areas protected by the hearth-guard, this is taboo, with strict warnings that "injuring the tail will also split the family's fortunes." In appearance, its back skin droops to look like a cloak, casting a shadow-like figure in dimly lit rooms. This is why it is mistakenly thought to shapeshift into the dead, but the Old Nekomata dislikes unnecessary transformation. When it occasionally borrows the appearance of a grandmother, it is only to lull a child to sleep, making no sound and leaving behind only the scent of soot and ash. Though it does not show itself to travelers, during milestones of the house—such as taking in a groom or the first night in a newly built home—it taps its claws lightly under the floorboards to foretell fortunes. Three taps mean good luck; two mean beware of fire. If the lamp wick is damp, it smoothes it with its tongue; if the stove fire is too strong, it fans it weaker with its tail. In exchange for taking on these small daily troubles, a custom remains for the family to share the "edges of the meal" with it. Three grains of rice, a pinch of salt, and a little steam. As long as these are observed, the Nekomata will not bewilder humans, and the strange noises at night will be dismissed as mere "house creaks."

The Night Sparrow is a nocturnal attendant yokai widely told of in the mountains of western Japan, marked by revealing itself through its call. In Tosa it is said to look like a small bird, in Kitagawa and Iyo like a moth or butterfly, and its appearance is not fixed. When someone walks alone, it alternates between the rear and the front, chirping close to the ear and throwing off the walker’s rhythm. In Toyama Village a banishing chant is preserved, and people are warned that rashly trying to catch it brings night blindness. In Wakayama, by contrast, it is taken as a sign that wolves are near and as a protective omen against mountain evils. Related tales include the “okuri-suzume” of Nara and Kii and the “tamutori-suzume” of Kochi and Ehime. In Tsunoyama and Johen they are treated as the same, and avoidance methods include gripping one’s sleeve, setting three twigs upright, or reciting specific mantras. Its folkloric traits are its ambiguous visual form, interference through sound, and regional differences in whether it is seen as ill or auspicious.

The "white-faced, golden-furred nine-tailed fox" is exactly what the name says: a fox-spirit with a white face, golden hair, and nine tails. Today it is almost automatically understood as Tamamo-no-Mae's true form, but that image did not appear fully formed. It grew from several lines that merged over time: the nine-tailed fox of Chinese classics, the tale of Daji becoming a nine-tailed fox, the Japanese Tamamo-no-Mae legend, and the Sesshoseki tradition of Nasu. The older nine-tailed fox was not necessarily evil. The Shan Hai Jing makes the Qingqiu fox a man-eating beast, yet the nine-tailed fox was also treated in ancient China as an auspicious creature, and Japan received the idea that the nine-tailed fox could be a sacred beast. Nine tails, in other words, did not originally mark simple wickedness. They marked the extremity of otherworldly power. That power might bless kingship or destroy it; the uneasiness lies in that doubleness. Nor was Tamamo-no-Mae always the white-faced, golden-furred nine-tailed fox. Shinmei-kyo records her name, and Tamamo no Soshi gives the story of a beauty serving Retired Emperor Toba who is exposed as a fox. But in the older form the fox has two tails. Terashima Shuichi's account stresses that almost four centuries of rewriting stand between that tale and the tight identification of Tamamo with the Nine-Tailed Fox. Without that gap, the history of the legend's remaking disappears. The decisive change was the joining of Daji's fox to Tamamo. The story that Daji, beloved of King Zhou of the Shang, became a nine-tailed fox was amplified through Chinese commentaries and fiction and reached Japan early. In the late Edo period, Japanese yomihon connected Daji, the Indian Kayo-fujin, and Tamamo-no-Mae as previous bodies and incarnations of one fox. Ehon Sangoku Yofuden was especially important: it made a single fox-spirit bewitch rulers in India, China, and Japan, and fixed Tamamo-no-Mae as the Japanese manifestation of the white-faced, golden-furred nine-tailed fox. The Sesshoseki gave the fox a story after death. In the noh play Sesshoseki, the stone is not merely poisonous rock but the dwelling place of a fox-spirit still bound by obsession. A monk breaks and pacifies the stone through ritual power, changing fox-slaying into an act of salvation. Nasu Town's official tradition likewise says that the stone is the transformed fox that flew from India and China, joining the legend to the sulfurous landscape Basho described in Oku no Hosomichi. Tamamo-no-Mae does not end when she is exposed at court. She remains in Nasu as stone. Painting and performance made this doubleness visible. After the 1751 puppet play Tamamo-no-Mae Asahi no Tamoto, Tamamo appeared repeatedly in joruri and kabuki as a role that was both peerless beauty and fox-spirit. In Utagawa Kuniyoshi's Abe Yasuchika Praying over Tamamo-no-Mae, nine beams of light open behind the beauty, placing courtly grace and vulpine truth in the same image. Mirrors, reflected water, halos that become tails: all are devices for showing that Tamamo is a being who can be seen through. The terror of the white-faced, golden-furred fox lies not in teeth or claws, but in the fact that she first appears as beauty and intellect. She knows Buddhist texts, Chinese classics, waka, and court music; she answers questions without hesitation and earns trust and affection. She does not invade from outside. She is invited into the center. For that reason, force alone cannot expose her. Divination, prayer, mirrors, water, and the stories that keep retelling her are what bring the hidden fox into sight. At the same time, she is not an entirely foreign enemy. She arises from the same fox imagination as Inari's white fox, the hierarchies of tenko and kuko, the tenderness of fox-wife stories, and the fear of fox possession. As Tamamo-no-Mae she may tilt royal power; as the Sesshoseki she leaves poison in the land. Yet people pacify her, enshrine her, paint her, perform her, and keep her in memory. The white-faced, golden-furred nine-tailed fox is not evil that has been erased. It is evil that remains speakable after defeat.

This Nobusuma is a small animal that slips from the treetops and presses a cloth-like gliding membrane across a traveler's face. Its terror lies less in teeth or claws than in the instant loss of sight and breath. Something falls from above on a mountain path; a damp membrane clings to the skin; eyes and nose are covered, and direction disappears. That chain of bodily sensations is what turns an ordinary flying squirrel into a yōkai. Sekien's image does not make the creature enormous. Nobusuma is frightening precisely because it is small, agile, and hard to distinguish in the dark. Rather than confronting a victim like a serpent or oni, it drops from branches, eaves, or the shadow of a cliff at an angle the traveler has not considered. Its spread membrane resembles cloth, but is not cloth. That is the decisive difference from Fusuma: the white-cloth yōkai begins with an ownerless textile, whereas Nobusuma is born in the instant when an animal's body is mistaken for one. Understanding its attack as “covering the face” also reveals its closeness to the Nodeppō. Nodeppō is said to spit out something bat-like that covers a person's face and shuts their eyes. Nobusuma is variously linked to that projectile or described as the transformation of an old bat. Either way, the sequence is similar: first vision is taken, then breathing and orientation are disturbed, and finally blood or vitality may be drained. A moment of losing one's bearings on a mountain road has been rearranged into the behavior of a monster. Nor can Nobusuma be dismissed simply by saying that a real flying squirrel explains everything. The animal exists, but a person who sees a shadow glide overhead at night may not be able to identify it. In the mountains, bird and beast, cloth and shadow, wind-shaken branch and living body can collapse into one impression. Nobusuma inhabits that interval of uncertainty. Natural histories supplied the animal name, Sekien converted it into an image, and strange tales added blood drinking and the smothered face: knowledge did not erase the uncanny, but furnished it with material. This version preserves Nobusuma's position between a small mountain animal and a cloth tsukumogami. Its body is beast, its appearance cloth, and its conduct yōkai. The traveler has almost no time to decide which is which; fear arrives before the name. Nobusuma is therefore most vivid not as the hero of a grand legend, but as an apparition compressed into a single second on a dark road. Keeping it small makes the attack feel closer: it seems near enough to brush away by hand, yet cannot be shaken loose. Geographically, Nobusuma does not belong neatly to one prefecture. The cloth Fusuma can be tied to traditions in Sado and Tosa, but Nobusuma bears the stronger imprint of Edo publishing, which reworked a nocturnal mountain animal into a yōkai. This version begins from that print culture while placing the creature in forests, ravines, and wooded edges near settlements. What waits there is not a giant monster displaying itself in full, but a small patch of darkness already against the face by the time it has been noticed.

Nue does not name only one composite beast shot by Yorimasa. Jikkinshō imagines it as a small bird calling in the palace hall, while Book Four of The Tale of the Heike follows the Konoe-in incident, in which the cry of a shape-shifter fallen from a black cloud resembles that of the bird called nue, with a separate Nijō-in incident in which Yorimasa shoots “a shape-shifting bird called a Nue.” The widely circulated body of monkey, tanuki, tiger, and snake remains its best-known image today. Its parts vary among texts, however, and in the Noh play Nue, the spirit set adrift in a hollow boat appears at Ashiya and asks a traveling monk for salvation. The name’s depth lies in the overlap of bird name, uncanny bird, composite beast, and departed spirit.

An organized synthesis of the one-eared pig yokai found in Amami strange tales, presented alongside related lore of earless pigs and one-eyed pigs. The shared core is soul extraction by “passing through the crotch,” in which it closes the distance with a sudden leap and slips through from behind. It is told as a local, site-bound apparition that emits a strong animal-like stench and casts no shadow. Some accounts say it appears before lone women or pairs of women. Practical know-how to avoid it includes standing or walking with legs crossed to prevent it from passing through the crotch. Capture is said to be difficult, as it escapes pursuit with speed and powerful leaps.

Based on Edo-period sources, this depicts an old bear transformed into a yokai. It usually keeps to deep mountains and avoids human presence, but during famines or seasonal shifts it slips down to villages under cover of night to carry off livestock. Its upright gait can be mistaken for a human silhouette, and its tracks mingle human and bear prints. Tales of great strength tie it to local megalith lore, serving as an unspoken boundary marker for dangerous mountain zones. In slaying legends, communal coordination, selective use of hunting tools, and reverence for the mountain deity are emphasized, and the Oni-Bear is told as more than a mere beast—a symbol that brings calamity to those who break the laws of the mountain. Descriptions in early modern illustrated compilations heighten its uncanny nature while reflecting memories of real bear attacks, showing the intersection of folk environment and ghostly tale.

Following Toriyama Sekien’s Konjaku Gazu Zoku Hyakki, it bears a crane-like black body, eyes that gleam like lamplight, and a cry that trembles through its wings. Said to arise from the qi of a fresh corpse, it appears when sutra recitations or memorial services are neglected at temples. Framed by Chinese lore adapted in Japan and retold in Edo-period strange tales, it manifests less from rancor than from circumstances such as unfinished rites or temporarily laid-out bodies, serving as a cautionary apparition upholding temple norms. Sightings are momentary, vanish when approached, and leave scant trace. Its very form is an alarm, understood as a sign of improper or incomplete memorial observances.

In this version, we read the Osaki-gitsune as the "small fox clinging to family lineages." The terror of the Osaki-gitsune is not that it suddenly jumps out on a mountain path. Its terror lies in the fact that by being spoken of as possessing a house for generations—that the family is an "Osaki holder"—it completely alters the reputation of the entire family. The yokai does not appear before the individual; it rides upon the family name. The Osaki-gitsune functioned as an explanation for wealth. In village societies, when only a specific family became wealthy, the reason was sometimes spoken of not merely as effort or luck, but as the invisible power of a fox. This narrative contains both envy and fear. A wealthy family has power, but whether that power is legitimate is doubted. The Osaki-gitsune is an entity that translates economic imbalance into the form of a yokai. As an explanation for illness or possession, the Osaki-gitsune also played a major role. Unexplained ailments, sudden madness, and abnormal appetites were spoken of as fox possession, becoming subjects for prayers and exorcisms. Here, the fox does not just enter the sick person's body; it spreads the suspicion of "Who sent it?" and "Which family has it?" The belief in spirit possession expands bodily issues into issues of the family and the community. The proximity to the Kuda-gitsune enriches the reading of this version. Both are small fox spirits that possess houses and are tied to wealth and disease. However, while the Kuda-gitsune easily takes on the sorcerous image of bamboo tubes or Izuna magic, the Osaki-gitsune functions more strongly as a family's reputation. Whether they actually keep a fox cannot be confirmed. Even so, simply being said to "have it" sways marriage prospects and social interactions. The invisible fox has visible effects socially. The Osaki-gitsune in this version is less a yokai with the appearance of a small animal, and more a suspicion dwelling in a house. While the shape of its tail or the size of its body changes depending on the teller, the feeling that "there is something in that house" never disappears. The outline of the Osaki-gitsune is clearest when we shift our eyes from searching for yokai in the fields and mountains, to looking at family reputations. The power of the Osaki-gitsune lies not in visible possessions, but in the suspicion of invisible possession. Even without evidence of actually keeping a fox, if it is said that "that house has Osaki," the attitudes of those around them change. Before showing its form, the yokai begins to operate as a reputation. In this version, we read the Osaki-gitsune as a memory device of the village. A certain family has been rich since the old days, produces sick people, or is avoided in marriage. Such memories are bundled under the name of the fox. The Osaki-gitsune has the function of transforming individual incidents into the narrative of a single family lineage. Therefore, the cute image of a fox is insufficient for the Osaki-gitsune. Even though it is small, it sways the evaluation and future of a family. Though it is a fox yokai, what it truly bites into are human relationships. The small fox lurking in the house becomes largest in the eyes of the community. Precisely because it is invisible, this fox enters deep into the house. The fewer people who have seen its form, the harder it is to deny. Something no one can verify sways the judgments of marriage and association. The Osaki-gitsune demonstrates very sharply the process by which a yokai becomes a social fact. That slight invisibility is what makes the Osaki-gitsune remain for a long time.

A local apparition said to descend with peals of thunder during the seedbed season, feared for ravaging paddies. Rites to drive it off include cracking split bamboo, and folk custom sets bamboo poles in fields to mark a safe return path. It is understood less as a human-harming monster than as a personification of lightning disaster, and those who approach are said to have their vitality sapped and fall stupefied. Its diet and appearance are inconsistent, with traditions likening it to a weasel, a tanuki, or a cat.

This is Rokuemon, the supreme commander of the Awa tanuki residing in Tsuda-ura. Ruling as the grand general over all tanuki in Shikoku, he stands as the veteran leader at the pinnacle of the tanuki hierarchy, where they fiercely compete for the title of "Senior First Rank." He once took in Kincho as his disciple and attempted to have him inherit his legacy through a marriage to his daughter. However, after Kincho fled, Rokuemon eventually faced him as a mortal enemy on the banks of the Katsuura River. Following a massive three-day and three-night battle involving over six hundred tanuki, it is said he fell in a final one-on-one duel. Yet his name has been passed down through storytelling, films, and animation, and he remains vividly remembered today as the indispensable co-protagonist of the Awa Tanuki War.
