Female Yokai |
Yokai, Demon Women, and Ghostly Women

Yuki-onna is an apparition that takes the form of a woman on snowy nights, mountain roads in blizzards, and villages buried in white. The familiar image is of a young beauty in white who freezes people with her cold breath, but that is not the whole of Yuki-onna. In Tateshina, Nagano Prefecture, she is told of as a “spirit woman of the snow” who harms no one and carries felled trees across ravines by night to make bridges. A record from Niigata describes a woman who leaves blood-speckled footprints in the midnight snow and kills those she meets. In Akita she is a woman with a smooth, featureless face; in Shōwa Village, Gunma Prefecture, a threat mothers recited on snowy nights to children who cried or would not sleep; and in Wakasa Town, Tottori Prefecture, a white woman who arrives riding a heavy snowfall. Under the same name stand a harmless snow spirit, a deadly encounter, a child-minding phrase, and even a figure glimpsed only for an instant. The name’s history begins in haikai poetry before it appears in ghost-story collections. An early printed example with a confirmed publication date is a verse in the 1642 anthology *Takatsukuba*, compiled by Yamamoto Saibu; “Yuki-onna” was then repeatedly used in works such as *Kebukigusa*, *Yama no I*, *Konzan-shū*, and *Masuyama-i*. The word first invited the wit of imagining the whiteness and form of snowy scenery as a woman, then gradually acquired clearer contours as the name of a supernatural being. Volume five of *Sōgi Shokoku Monogatari*, published in 1685, describes a young white woman about one jō—roughly three meters—tall, standing beside bamboo in Echigo. Her face, hair, skin, and even her unlined white robe are translucently white; a companion explains that she is a snow spirit taking human form. Although the title bears the name of Sōgi, this is not the travel journal of a fifteenth-century renga poet. It is a kana-zōshi of 1685 that borrows Sōgi’s persona as a traveler to tell tales of curiosities from around the country. Sawaki Sūshi’s *Hyakkai Zukan* (1737) and Toriyama Sekien’s *Gazu Hyakki Yagyō* (1776) place Yuki-onna in an image as a named yōkai in her own right. Sekien’s page gives only the name “Yuki-onna”; it does not say that she freezes people with her breath, seduces men, or fears fire. Yōkai pictures made a form easier to share, but did not supply every later story at once. The best-known story today is “Yuki-Onna,” which Lafcadio Hearn included in *Kwaidan* in 1904. In a ferry hut during a blizzard, Yuki-onna freezes the old woodcutter Mosaku to death with her white breath, then spares the young Minokichi and orders him to keep the night secret. The following winter she appears as Oyuki, a traveling woman, becomes his wife, and raises ten children. When her husband tells the forbidden memory, she reveals herself; for the children’s sake she does not take his life, but leaves as white mist. This marriage, secrecy, maternal attachment, broken promise, and separation made Hearn’s Oyuki especially memorable, but they are not traits shared by every local Yuki-onna. The appeal of the name Yuki-onna is that it does not close around a single setting. Snow erases roads, absorbs sound, and transforms distance and shape. In different places and periods, people who looked at snow found a young woman, a mother, a giant face, or a wavering shadow within it. Yuki-onna is the whole accumulation of those images.

Ubume is a Japanese supernatural phenomenon (yokai) widely believed to be the spirit of a woman who died during childbirth or shortly after, appearing in the form of a woman cradling an infant. In many tales, she stops passersby at night at river crossings, bridges, and crossroads, pleading with them, "Please hold this child." The outcome varies depending on the region and the source: the baby received might suddenly become heavy, turn into leaves or a stone, or the person who manages to hold onto it until the end might be granted superhuman strength or wealth. Therefore, the Ubume is not merely an evil spirit that attacks people. She is an entity that gathers the severed bond between mother and child, the fear of the dead, and the courage and compassion of those who accept her plea into a single tale of an encounter. A famous surviving early example is found in the first half of the 12th century in *Konjaku Monogatari Shu* (Tales of Times Now Past), Scroll 27, Tale 43, "How Minamoto no Yorimitsu's Retainer, Taira no Suetake, Met an Ubume." When Minamoto no Yorimitsu was the Governor of Mino, his retainer Taira no Suetake went to a dark river crossing at night as a test of courage, where he was entrusted with a baby by a woman in the river. Upon returning to the mansion and opening his sleeve, he found only a few tree leaves. At the end of the tale, the narrator juxtaposes the theory that the Ubume is a shape-shifting fox with the theory that she is the spirit of a woman who died in childbirth, without deciding on her true identity. At this stage, the blood-stained waistcloth and bird feathers that became famous in later eras had not yet been depicted. On the other hand, care must be taken with the notation that writes "Kōkakuchō" (Guhō bird) but pronounces it "Ubume." The "nocturnal roaming woman" described in Scroll 16 of the Tang dynasty text *Youyang Zazu* (Miscellaneous Morsels from Youyang) is a Chinese monster bird that becomes a bird when wearing feathers and a woman when taking them off, and has a habit of snatching people's children. Because it involved babies and women who died in childbirth, it was conflated with the Japanese Ubume, but they originally belonged to different lineages. According to the research of Manami Yasui, Hayashi Razan, who assigned the Japanese name to the Chinese Kōkakuchō, first specified in the 1631 *Shinkan Tashikihen* that "Kōkakuchō" is the "Ubume-dori" (Ubume bird) or Nue. While the Japanese Ubume has as its core "a mother's spirit entrusting her own baby to someone else," the Chinese Kōkakuchō has as its core "a bird monster that snatches other people's children." Understanding this difference reveals how the yokai known as Ubume changed its form by layering medieval tales, memorials for those who died in childbirth, knowledge of monster birds from China, and early modern yokai illustrations.

Tamamo-no-Mae is a beauty of unrivaled grace who, in the late Heian period, is said to have served the retired Emperor Toba. Her true form is held to be a nine-tailed fox, yet as a human, Tamamo-no-Mae has above all been remembered as a court lady of rare beauty and deep learning. Poetry and music were a given, but from Buddhist scripture to the old tales of India and China, she answered any question without hesitation, astonishing all at court. The name “Tamamo-no-Mae” carries a story of its own. One night, amid a banquet of poetry and music at the Seiryōden, a gust of wind snuffed out the lamps; in the darkness a dazzling light streamed from her body and lit the hall as bright as day. From this she came to be called “Tamamo-no-Mae,” meaning the lady of the jewel-like, glowing waterweed . Before that, it is said, she had been called Mikuzume. In time she drew all the emperor’s affection to herself, but when he fell ill from an unknown cause, her true nature began to be doubted.

The jorōgumo is a Japanese yokai whose popular image coalesced from several distinct traditions: the name of a living spider species, early modern ghost stories of spiders transforming into women, Toriyama Sekien’s woodblock illustrations, and regional legends of spider pools (*kumobuchi*). Rather than a single beautiful woman dwelling at a specific waterfall, its appearance and behavior vary widely across historical eras and literary records. The written title 絡新婦 was not coined as a literal description meaning "a bride who entangles people." The *Wakan Sansai Zue* glosses the characters 絡新婦 with the reading *chorōkumo* and notes that it is "commonly called *jorōgumo*". The written name represents an intersection between a spider name found in classical Chinese materia medica and the spoken Japanese word *jorōgumo*. Tales of spiders appearing in female form predate Sekien’s art. In the 1677 collection *Tonoigusa*, a samurai grows suspicious of a young woman carrying a child and strikes her with his sword; the following day, he finds a slashed, dead *jorōgumo* alongside numerous human skeletons in the ceiling crawl space. In the 1732 collection *Taihei Hyaku Monogatari*, a man named Magoroku from Sakushū Takada is invited by an older woman into an illusory mansion where a young maiden urges him to marry her; when he flees, he returns to his own veranda, only to discover a tiny *jorōgumo* and an enormous cluster of webs beneath the eaves. Magoroku is not devoured; the narrative centers instead on the hazy boundary between dreams and illusions. In his 1776 work *Gazu Hyakki Yagyō*, Toriyama Sekien gave the title "Jorōgumo" (絡新婦) to an illustration depicting a long-haired woman in flowing robes overlaid with spider legs, surrounded by a swarm of tiny spiders. Wavy lines extending from the spiderlings suggest silk threads, smoke, or fire, but the print includes no explanatory text, nor does it depict a musician seducing a man. A bibliographic investigation conducted by the National Diet Library likewise found no classical literary source that matches the popular modern story of a beautiful woman playing a biwa lute to lure men and ultimately devour them. Waterside traditions of the jorōgumo reflect an entirely separate layer of folklore. Tales of "spider pools" (*kumobuchi*)—in which a spider attaches a thread to a person's foot, only for the individual to shift the silk onto a tree that is then dragged into the water—are distributed throughout Japan. At Jōren Falls, this thread-shifting motif merged with a taboo legend about a woodcutter who retrieves his dropped hatchet from a beautiful woman and dies after breaking his promise of silence, creating the famous Jorōgumo lore known today. Recognizing the differences among these sources reveals the jorōgumo not as a simple seductress, but as a yokai that mirrors human carelessness toward tiny creatures, the boundary between dreams and reality, the hazards of waterside terrain, and the cultural process by which names and images weave disparate legends together.

Rokurokubi is known as a yōkai whose neck stretches unnaturally long at night. Read older books in chronological order, however, and no single form emerges. Under the same name gather figures close to the nukekubi, whose heads separate completely and fly; people who experience the event only as a dream; bodies and heads that appear linked by a thin line; and figures able to lengthen a long neck at will. The earliest currently identifiable candidate for the name is "rokurokubi" in volume two of the haikai anthology *Takatsukuba*, listed by the *Nihon Kokugo Daijiten* as an example from 1638. Yet surviving bibliographic records also date the book to 1642, so the original must be checked again before calling it an absolute first appearance. The name "Rokurokubi" appears in *Seishō Senku* in 1648, and the title "Rokurokubi of Fuchū in Echizen Province" appears in *Shokoku Hyaku Monogatari* in 1677. These early examples show that the name was spreading from the middle to late seventeenth century. In *Sorori Monogatari*, set in Echizen, a man meets a woman's head on a night road and follows it; when the head flies into a house, the sleeping woman says she has dreamed the frightening dream of being pursued by him. Ashamed of her own deluded thoughts, she enters Buddhist practice, but the story does not say she became a monster through jealousy. The strange event is one in which a person's mind or soul seems to have left the sleeping body. China's *Soushen ji* includes a woman of the Luotou people whose head flies by night and returns to her body at dawn. In the *Youyang zazu*, the Feitou Liaozi develop a ringlike red mark on the neck, sprout wings from the head, and eat crabs and earthworms. These closely resemble Japanese detached-head forms, but they do not prove that Chinese tradition simply became a Japanese yōkai. In Japan, knowledge from Chinese texts, ghost stories, illustrated books, and comic kibyōshi overlapped to shape several images of the rokurokubi. The 1737 *Hyakkai Zukan* depicts a nukekubi, while Toriyama Sekien's *Gazu Hyakki Yagyō*, first published in 1776, presents Hitōban (飛頭蛮) with the reading "rokurokubi". In Sekien's image, a sleeping woman's body and floating head are joined by a slender line. One study argues that such lines were later represented as elongated necks. In *Kyōgen Suehirogari* (1788), the neck of a woman in love stretches from Edo to Kamigata, producing laughter rather than fear. Lafcadio Hearn's "Rokuro-Kubi," included in *Kwaidan* in 1904, is not about a beautiful woman with a long neck. Kwairyō, a samurai turned monk, meets five headless bodies and five heads flying through woods in the mountains of Kai; he moves one body to prevent a head's return and fights the attacking head. Its direct source story is an episode in volume four of Jippensha Ikku's *Kaibutsu Yoron*. The red writing, the tactic of moving the body, and power limited until dawn belong to this particular line of tales.

Futakuchi-onna is a yokai woman said to have a second mouth on the back of her head. She hides it under her hair, but when hunger strikes, her hair writhes like snakes and the rear mouth clamors for food on its own. Featured in strange-tale collections such as Ehon Hyaku Monogatari (1831), the legend often serves as a caution against extreme frugality and secretiveness. Outwardly she appears human, but at the nape a sharp-toothed mouth with a tongue is said to lurk.

An old witch-like yokai who dwells deep in the mountains. She is also known as the foster mother of the folk hero Kintaro.

Kijo is a collective term for women transformed into oni through rancor, karma, or jealousy. The youthful form is called kijo; in old age, onibaba. They appear widely in classics, legends, and performing arts—famous figures include Kureha (Momiji) of Togakushi/Kijinashi, Suzuka Gozen of Mount Suzuka, and the demon crone of Adachigahara (Kurozuka). Tales tell of them beguiling people, haunting the night to waylay travelers, and preying on infants or pregnant women, often framed by beliefs in curses and karmic retribution.

Kiyohime is the serpent woman from the legend of Anchin and Kiyohime, passed down at Dojoji Temple in Kii Province. She fell in love with Anchin, a monk on a pilgrimage to Kumano. Believing he broke his promise, she chased him across the Hidaka River, transformed into a giant serpent, and burned Anchin to death as he hid inside the temple bell at Dojoji. Dojoji Temple claims this story took place in the year 928 (Encho 6) and it was recorded in the 11th-century *Hokke Genki*, later expanding into the "Dojojimono" plays of Noh, Ningyo Joruri, and Kabuki . In older tales, the woman's name was not fixed; she became established as "Kiyohime" through later temple legends, picture storytelling (etoki), and performing arts. As a yokai, Kiyohime is not a serpent deity in her own right, but a liminal being whose human love was burned by jealousy and obsession into a serpentine form. Much like Hannya and Hashihime, she is a representative demoness (kijo) whose grudge gained a face, a body, and fire.

Hashihime is a figure born from ancient water and land deities fused with beliefs in bridge guardians. Revered at old great bridges, she is known as a goddess or ogress. A shrine to her stands at Uji Bridge on the Uji River, with traditions also tied to Nagara Bridge and Karahashi at Seta. Taboos warn against praising other bridges while standing on a bridge, or singing songs of jealousy there. She appears in the Kokin Wakashū, and later lore recasts her as a woman transformed into a demon by jealousy.

Bone Woman is a skeletal female yokai depicted by Toriyama Sekien in Konjaku Gazu Zoku Hyakki. In his notes, Sekien cites otogizōshi-style ghost tales in which a woman bearing a peony-patterned lantern visits her lover, drawing on the female specter from Asai Ryōi’s Otogibōko story “Botan Dōrō.” The image embodies a beauty who approaches a man but is in truth bare bones—a visualization of the uncanny where desire and death intersect.

Iso-onna is a female sea apparition found along the northwestern coast of Kyūshū, including Amakusa, Shimabara, Tsushima, and Kakarashima. She approaches beaches, rocky shores, and moored boats, entangling people in her long hair and drinking their blood. Her upper body resembles a beautiful woman, while her lower half is said either to fade from view or to be serpentine; from behind, she may look like nothing more than a wet rock. Names vary by region, including Iso-joshi, Nure-joshi, Ama, and Umi-hime. She appears when the sea is calm and is sometimes linked with the resentful dead of maritime disasters. Some traditions also pair her with Ushi-oni, another dangerous being of the shore.

Nure-onna is a waterside apparition with a woman's head and the body of a serpent. Below the waist, an immense scaled body replaces human legs; above it hangs the perpetually wet black hair that gives her the name 'Wet Woman.' In the wind volume of Toriyama Sekien's Gazu Hyakki Yagyō, she appears as a female face on a serpent's body, her long hair trailing in the water. Serpentine women also appear in earlier Edo picture scrolls such as Sawaki Sūshi's Hyakkai Zukan, showing how artists passed the image from one work to another. Stories from western Japan give Nure-onna a different but equally memorable role. She presses the baby in her arms upon a passerby; the moment it is accepted, it becomes as heavy as stone and leaves the victim unable to move. In some versions, Ushi-oni then attacks. Nure-onna is often discussed alongside Kyūshū's Iso-onna and regional traditions of Nure-onago, and has also been interpreted as a sea serpent transformed. Yet the serpent body is supported chiefly by paintings, and primary evidence directly linking every local tale to that image is scarce. Wet hair, the water's edge, and a child that binds the recipient are the more stable features shared across western Japan's female water apparitions.

A female yokai depicted by Toriyama Sekien in Gazu Hyakki Yagyo. She is known for stretching her lower body up to the height of a building’s second floor to peer through windows. Sekien’s original print includes no notes, so her nature and identity remain uncertain. Later writers imagined her startling patrons on the upper floors of brothels, but historical sources mostly present her as a visual motif without fixed tales or a settled etymology—an emblem of a strange figure that peers from high places.

A feminine yokai or spirit associated with calling rain. Toriyama Sekien includes the subject “Ame-onna” in Konjaku Hyakki Shūi, but his treatment leans on the Chu poet Song Yu’s tale of “morning cloud, evening rain,” using it satirically rather than defining a concrete monster. In folk belief she is feared as a figure who appears on rainy days to snatch children, yet also revered as a rain-bringing spirit who ends drought.

The Shadow Woman is a feminine apparition drawn by Toriyama Sekien in Konjaku Hyakki Shūi. In houses haunted by spirits, only the silhouette of a woman appears on the shoji under moonlight. She manifests as a shadow, with no clear physical body. Sightings occur at night—especially in strong moonlight—and are described less as attacks and more as an ominous sign. Explanations vary: a restless ghost, a house-bound entity, or a spirit of moonlight; her true nature remains unknown.

A female yokai depicted by the Edo-period artist Toriyama Sekien in Konjaku Hyakki Shūi. She peers over a wall with her mouth agape, cackling kera-kera to bewilder passersby. Sekien alludes to a Chinese anecdote by Song Yu, likening her to the spirit of a woman whose coquettish laughter unsettled hearts. No specific locale or backstory is given; later tradition remembers her as a eerie, laughing apparition.

A yokai named in the Edo-period collection Ehon Hyaku Monogatari. Framed as a Buddhist admonition, it serves as a metaphor for the folly of being ensnared by a woman’s allure. Her outward beauty is likened to a bodhisattva, while her inner nature is as fearsome as a yaksha. Men whose hearts are unsettled by her are warned to lose their homes and ruin themselves. The name can be read as “calamity flying in on karmic ties,” and it has been linked to folk beliefs about women born in the year of Hinoe-uma (the fiery Horse).

Hari-onago is a female yokai associated with the Uwajima region of southern Ehime. She looks like a beautiful woman, but the ends of her dishevelled hair curl into barbed, fishhook-like points. The Mizuki Shigeru Road account gives the reading *hari-onago* and places her around Uwajima: on a night road she smiles at a man, waits for him to smile back, then closes the distance and whips out the hooks in her hair to catch and drag him away. The fear lies less in a monstrous appearance than in the instant when an ordinary encounter becomes a trap. The documentary trail is short. Mizuki Shigeru’s *Zusetsu Nihon Yōkai Taizen*, catalogued by the National Diet Library, helped circulate the name through postwar yokai encyclopedias. The *Nihon Yōkai Daijiten* notes how closely the figure overlaps with Nure-onago from the same part of Ehime and raises the possibility that Mizuki sharpened those traits under the name Hari-onago. It is therefore best understood not as a major creature fixed in ancient texts, but as a night-road apparition from Nanyō whose present identity became clear through Mizuki’s retelling.

Ohaguro-bettari appears as a bride or young woman who keeps her face hidden. When someone approaches, she turns to reveal smooth white skin with neither eyes nor nose—only an enormous mouth of blackened teeth. *Ohaguro* was the historical practice of dyeing the teeth with an iron-based solution; *bettari* suggests that the blackness has been laid on thick. In the *Ehon Hyaku Monogatari*, bridal beauty and the sudden absence of a face are made to reverse into one another in a single image. Blackened teeth were not inherently monstrous. Ohaguro belonged to a history of marriage, adulthood, status and women’s formal appearance. Hara Mitsumasa’s study of ohaguro treats it as folklore and bodily adornment, reminding us that black teeth once signalled beauty and social maturity. The yokai becomes frightening when that familiar sign expands until it erases every other feature. Noppera-bō embodies the fear of having no face; Ohaguro-bettari sharpens it into the fear of having nothing but a mouth. A traveller sees a shy bride, steps closer, and finds no eyes returning the gaze—only a black smile opening across blank skin. The point is not simply a resentful unmarried woman. The image turns the etiquette of makeup, weddings and modestly hiding the face into a visual trap, transforming a recognised sign of beauty into the whole substance of the horror.

A strongly imaginative yokai depicted in Toriyama Sekien’s Konjaku Gazu Zoku Hyakki and Edo-period kibyōshi. As the name suggests, it appears as a courtesan whose entire body is shrouded in long hair; her face is hidden by hair, or in some readings, absent altogether. Considered a satirical presence in the pleasure quarters, the wordplay links the painted “makeup” of a courtesan with “apparition.” It lacks stable local folklore and is known mainly from printed sources.

A lady-in-waiting–type yokai seen in Edo-period monster paintings. In Toriyama Sekien’s Konjaku Gazu Zoku Hyakki, she appears as a youthful court woman with ohaguro (toothed blackening), said to haunt a ruined old palace. The term originally referred to low-ranking young attendants serving at court or in aristocratic households, and was not a fixed monster name. Similar court-attendant figures appear across various Hyakki Yagyo picture scrolls; Sekien likely labeled that iconography as “Ao-nyōbō.” Her nature and origins are unknown.

Established in prominence during the Heian period by Taira no Kanemori's poem in the *Shui Wakashu* (1006)—"Is it true what I hear, that a demon hides in the Black Mound (Kurozuka) of Adachigahara in Michinoku?"—this is the legend of the hag (Onibaba) of Adachigahara in Mutsu Province (modern-day Nihonmatsu City, Fukushima Prefecture). She is the ultimate embodiment of the yokai archetype of the "mountain crone who shelters travelers, only to attack them at midnight and devour their livers." Dramatized as the Noh play *Kurozuka* (Adachihara) by Kanze Kojiro in the medieval Muromachi period, and further perfected as the Joruri and Kabuki play *Oshu Adachigahara* (premiered 1762) by Chikamatsu Hanji and others during the Edo period, it remains the most representative Japanese hag legend, still performed today. The primary site of the legend is Kanze-ji Temple (founded 727, Nihonmatsu City), where the "Kurozuka" within the precincts is said to be her burial mound. The tragic narrative of her true identity, "Iwate"—who, in her desperate search for a liver to cure her mistress, unknowingly murders her own daughter—was added in later eras, deepening the tale from a simple monster story into a profound human tragedy.

Kuzunoha is a shape-shifting fox living in the Shinoda Forest who becomes a human wife and is later spoken of as the mother of the onmyoji Abe no Seimei. While the core of the story is a tale of a fox's transformation, it places gratitude, the bond between husband and wife, and the parting of mother and child at the forefront, rather than the terror of shapeshifting to deceive humans. The plot—a fox saved in the Shinoda Forest transforms into a woman named Kuzunoha, marries Abe no Yasuna, and gives birth to Dojimaru—was largely solidified as "The Kuzunoha Fox" in early modern joruri and kabuki theater. In the bibliography of the National Diet Library, one can find the Ashiya Doman Ouchi Kagami lineage, which includes the title Shinoda-zuma Urami Kuzunoha (The Wife of Shinoda: The Sorrowful Kuzunoha). Kuzunoha has become more than just a fox wife; she is an entity that illuminates the Seimei legends from the perspective of a mother's story. A characteristic of Kuzunoha is that her fox spiritual power is manifested inside the home. While the Nine-Tailed Fox or Tamamo-no-Mae often wear outward-facing demonic power that shakes royal authority, Kuzunoha's power dwells in domestic scenes: sliding doors (shoji), the delivery room, the child's name, and the waka poem left at her departure. When her true identity is revealed, the fox has no choice but to leave her child and return to the forest. The poem she leaves behind—"If you long for me, come seeking me in the forest of Shinoda in Izumi, the sorrowful Kuzunoha"—causes Kuzunoha to be remembered not as a terrifying monster, but as a mother who crossed boundaries. The Ashiya Doman Ouchi Kagami: Abe Yasuna, Kuzunoha, and Yokanpei in the Izumi City Digital Archive also conveys the scene of parting with her child, showing that the image of Kuzunoha was cultivated both on stage and in iconography. Therefore, among fox yokai, Kuzunoha is an entity who makes us question "what she tried to protect even by shapeshifting" rather than her "ability to shapeshift." The land of Shinoda Forest, the name Abe no Seimei, the folktale of the fox wife, and the programs of kabuki and bunraku overlap, and she stands as a legendary figure who, despite being a yokai, bears the sorrow of motherhood and an inter-species marriage.

A female yokai and castle deity said to dwell in the main keep of Himeji Castle. Early Edo怪談 depict it as a gender-shifting castle specter; later tradition fixed the image as a “princess.” Revered and feared as both guardian and avenger of the castle, bringing fortune or calamity according to the lord’s conduct. Its true nature varies by tale—an ancient fox, a castle god, a sacrificed woman, or the spirit of a long-departed noble lady. Also called Osakabe.

Takiyasha-hime is a legendary sorceress whose lineage is linked to Taira no Masakado and who took vivid shape in late Edo-period yomihon, kabuki, and ukiyo-e. Neither her familiar name nor her familiar story appears unchanged in records from the Heian period. The *Konjaku Monogatari-shū* tells of Nyozō, the third daughter of Taira no Masayuki, who became a nun and devoted herself to Jizō. The medieval *Genkō Shakusho* recast her as the third daughter of Taira no Masakado, but its Nyozō was not yet a sorceress leading a rebellion. The decisive turn came with Santō Kyōden’s *Uto Yasukata Chūgiden*, published in 1806. Kyōden wove Masakado’s surviving son Taira no Yoshikado, Nun Kisaragi, Nikushisen, toad magic, and the ruined Sōma Palace into a single supernatural tale. In this yomihon, Nun Kisaragi becomes “Takiyasha-hime,” written 滝夜刃姫, and joins Yoshikado and his allies in a story of restoring Masakado’s cause. A woman from a quiet religious tale had become a rebel princess carrying the memory of the defeated. The stage created another distinct incarnation. In *Shinobu Yoru Koi wa Kusemono*, first performed in 1836, Takiyasha-hime disguises herself as the courtesan Kisaragi and approaches Ōya Tarō Mitsukuni before revealing her identity and fighting him with magic. Transformation, seduction, a giant toad, and a spectacular collapsing set gave the sorceress princess both glamour and terror in a form uniquely suited to kabuki. The image that made her famous around the world was Utagawa Kuniyoshi’s triptych *Princess Takiyasha Calling up a Monstrous Skeleton Specter at the Old Palace in Soma*, created around 1845–46. Kuniyoshi condensed the swarm of skeletons in the source story into one colossal figure bursting through the blinds. The skeleton was Kuniyoshi’s bold visual invention, not a contemporary depiction of the postwar yokai later named Gashadokuro. When the later association between the two images is included, Takiyasha-hime emerges not as one fixed figure but as a sorceress continually reshaped by religious tale, yomihon, stage, and woodblock print.

Suzuka Gozen is a boundary female spirit dwelling on Mount Suzuka and the Suzuka Pass, the border between Ise and Omi Provinces. She is variously depicted as a goddess, a heavenly maiden (tennyo), a female bandit, or an oni woman (kijo). Also known as Suzuka Hime, Suzuka Daimyojin, Suzuka Gongen, and Suzuka Shinjo, she was later conflated with Tate-eboshi of Mount Suzuka. In the Tamura narratives from the Muromachi period onwards, she becomes the partner of Tamuramaru (modeled on Sakanoue no Tamuramaro) and aids him in slaying demon gods like Otakemaru. However, she is no mere damsel in distress waiting for a hero. Embodying the guardian deity of the pass, the memory of bandits who threatened travelers, and the divine authority of a goddess descending from heaven, she provides Tamuramaru with the strategies necessary to defeat the mountain's demon gods. Suzuka Gozen is the very personification of the Suzuka Pass, standing at the crossroads between the capital and the eastern provinces, gods and demons, and protection and rebellion.

Female Tengu are the female-identified beings among the tengu. They are depicted with long hair, eyebrows darkened with ink, rouge and white powder on the face, teeth blackened with ohaguro, and dressed in scarlet hakama and gauzy robes, sometimes with wings on their back. Classical sources mention nuns who fall and become “nun tengu,” though records differ on whether women exist in the tengu world at all. Some regions describe river tengu with feminine traits, but details remain unclear.

Hannya is a Noh mask for a female demon: two horns, gold-colored eyes, fangs, and a wide, split mouth convey rage, while sorrow still lingers in the expression. In the Noh plays Aoi no Ue, Kurozuka, and Dojoji, a Hannya mask is used to bring to the stage a woman turned demon through jealousy or resentment, or the vengeful spirit of a woman. It is a type of mask, not the name of one distinct being such as Yuki-onna or Kappa. The Nohgaku Performers' Association names Hannya among the representative masks for vengeful spirits, whether of the living or the dead. Its expression is not fashioned from anger alone. A description of the "Omi-uchi" Hannya in the Tokyo National Museum explains that the horns, gold-colored eyes, fangs, and split mouth signify rage, while the inverted-V upper eyelids and the disordered strokes of hair across the forehead carry sadness. The mask is frightening and poignant at once because, even as it inclines toward demonhood, it never wholly loses the trace of a human face. The word hannya originally means Buddhist wisdom. In Toriyama Sekien's Konjaku Gazu Zoku Hyakki, the entry begins by calling hannya the name of a sutra, then tentatively suggests that the name for a mask depicting a woman turned demon may derive from the phrase “hannya-goe” in the Noh play Aoi no Ue. The claim that the mask was made by Hannya-bō does not appear in Sekien's commentary; it belongs to a separate tradition about the name's origin. Hannya has a place in yokai encyclopedias because Sekien presented it as an independent illustrated subject in his 1779 Konjaku Gazu Zoku Hyakki. A Noh mask can be worn for several different roles, but Sekien's book presents Hannya as the name of a marvel alongside oni, Hashihime, and Shuten Doji. Hannya has moved between several cultural layers: Noh mask, female-demon role, Edo-period yokai image, and modern mask iconography.

Datsue-ba is a hag from Japanese Buddhism and folk religion who resides at the Sanzu River, the boundary of the underworld. She sits on the riverbank and plays the role of stripping the clothes from the dead who arrive without the six-mon toll fee. Her counterpart, an old man named Kenne-o, then takes these stripped clothes and hangs them on the branches of a large tree called the Eryoju (Clothing-Receiving Tree). The degree to which the branches bend under the weight of the wet clothes determines the gravity of the sins the person committed in life—making this an extremely visual and quantitative mechanism of underworld judgment. Her first appearance in scripture is in the *Sutra on the Cause and Effect of Jizo Bodhisattva and the Ten Kings*, a Japanese apocryphal sutra from the late 12th century, an adaptation of a Chinese text. From the Kamakura period onward, she became a staple figure in preaching and picture-scroll storytelling. In the Edo period, she evolved into a popular deity for curing coughs (known as the 'Cotton Hag' at temples like Shoju-in in Shinjuku) and became deeply rooted in mass culture, frequently appearing in nishiki-e (woodblock prints) from 1849 through the Meiji era.

Yao-bikuni is the legend of a Buddhist nun who lived for an astonishing span of time, told in Wakasa and throughout Japan. The best-known story tells of a girl who eats mermaid flesh, grows old only very slowly, enters religious life, and travels the provinces. The surviving records, however, do not contain one single story: her appearance, age, and reason for longevity all vary. The most important early records place her in Kyoto in 1449. The entry for the twenty-sixth day of the fifth month of Bun’an 6 in *Yasuyoshi-ki* describes a “Shiro-bikuni” from Wakasa as more than two hundred years old and says that many people came to see her. In the entry for the twenty-sixth day of the seventh month of the same year, *Gaun Nikkenroku* calls a nun from Wakasa an “eight-hundred-year-old nun” and says that people in Kyoto paid to see her. Neither account mentions mermaid flesh; both foreground a long-lived nun who had become a sensation in the capital. The explanation of longevity through mermaid flesh becomes a clear story in the early modern period. In Hayashi Razan’s *Honchō Jinja Kō*, a father receives a mermaid from a stranger in the mountains, brings it home, and his daughter eats its flesh, becoming more than four hundred years old. The sequence of father, otherworld, mermaid, and daughter became a defining form of later Yao-bikuni stories, though even here the lifespan is not fixed at eight hundred years. Yao-bikuni’s name also became attached to old trees, temples, and caves. Before Kūin-ji in Obama, Wakasa, lies a sacred cave associated with her entering meditation; at Jigen-ji in Musashi, a great Chinese hackberry was said to have been planted by Yao-bikuni. The long-lived nun is both a traveler and a name through which distant places tell the age of their own landscapes. In the major medieval and early-modern sources, Yao-bikuni is not a ghost but a legendary person in whom wonder at longevity, fear of otherworldly food, and memories of itinerant female religious practitioners overlap.

Oiwa is the protagonist of Japan's most widely known ghost story, renowned as a female ghost who was betrayed and poisoned by her husband, dying with a disfigured face and returning as a terrifying, vengeful spirit. However, this image is almost entirely a theatrical fabrication. In the kabuki play "Tokaido Yotsuya Kaidan" (written by Tsuruya Nanboku IV and premiered at the Edo Nakamura-za in 1825), the role of Oiwa was played by Onoe Kikugoro III. The iconic scenes—where she dies while combing her hair with half her face terribly swollen and decaying, washes ashore nailed to a wooden door, and later emerges from a burning lantern to torment her husband—established the archetype of the vengeful ghost Oiwa. Importantly, the real woman behind the legend was said to be the exact opposite. Oiwa (Tamiya Iwa), the wife of the Tamiya samurai family living in Samoncho, Yotsuya, was known as a devoted and faithful wife with a deeply loving marriage. She devoutly worshipped the family's Inari shrine and successfully restored her family's declining fortunes, making her an auspicious figure. The Oiwa Inari (Tamiya Inari) shrine dedicated to her was originally visited as a "god of luck that brings family prosperity." The name Oiwa stands upon the immense contrast between the historical virtuous wife and the vengeful spirit crafted by Nanboku two centuries later.

Okiku is the vengeful ghost of a woman who was drowned in a well over the suspected loss of a single heirloom plate, returning every night to the bottom of the well to count plates: "One... Two..." She features in two major lineages of legends: the *Banshu Sarayashiki* tradition set in Harima (Himeji), and the *Bancho Sarayashiki* tradition set in Bancho, Edo. Alongside Kasane and Oiwa, she is considered one of the most representative female vengeful spirits of early modern Japanese ghost stories. In the Banshu lineage, amid Aoyama Tetsuzan's conspiracy to usurp the Kodera (Hosokawa) clan during the Muromachi period, his retainer Machitsubo Danshiro hides one of ten heirloom Chinese plates, pins the blame on the maid Okiku, tortures her to death, and throws her into a well. In the Bancho lineage, Okiku is a maid in the mansion of the hatamoto Aoyama Shuzen who breaks a plate—or refuses her master's unwanted advances—and is slain and cast into a well. Both versions share the core motif of a cyclical haunting where she counts the incomplete set of plates, climaxing in an agonizing shriek when she reaches the missing piece. The Okiku Well still exists beneath the main keep of Himeji Castle, and the legend has taken deep root even in local place names, shrines, and the names of insects.

Otsuyu is the legendary female ghost protagonist of the ghost story *Botan Doro* (The Peony Lantern). Said to be the daughter of the hatamoto Iijima Heizaemon, she falls in love at first sight with the ronin Hagiwara Shinzaburo, whom she met through the introduction of the physician Yamamoto Shijo. However, unable to meet him again, she is said to have passed away from lovesickness. Unable to let go of her feelings even in death, she visits Shinzaburo every night accompanied by her maid Oyone, carrying a peony lantern, her wooden clogs echoing with a 'clippity-clop' (karan-koron) sound. After discovering her true identity as a spirit, Shinzaburo wards his house with the talismans of Kaion Nyorai and a solid gold Buddha statue. However, his neighbors, the married couple Tomozo and Omine, are bribed by the ghosts to peel off the talismans. Shinzaburo is ultimately cursed to death; he is found reduced to a skeleton, embraced by a skull. Because the story strongly evokes empathy for the dead rather than the living, Otsuyu is remembered not merely as a 'vengeful ghost,' but as a 'ghost who died for love and continues to love.' Alongside Oiwa of *Yotsuya Kaidan* and Okiku of *Sarayashiki*, she is counted among the most iconic female ghosts of early modern Japanese ghost stories.

Kuchisake-onna (Slit-Mouthed Woman) is a representative modern urban legend of post-war Japan that originated in Gifu Prefecture between 1978 and 1979 and spread nationwide. The typical pattern involves a beautiful woman covering her mouth with a mask who stops children on the street at night and asks, "Am I pretty?" Depending on the answer, she removes her mask to reveal a mouth slit from ear to ear, asking again, "Even like this?"—if denied, she attacks with scissors or a carving knife. It is said to have first appeared in the "Editor's Notes" column of the Gifu Nichinichi Shimbun on January 26, 1979, and from March 1979, national magazines such as Shukan Asahi, Shukan Shincho, Shukan Josei, and Josei Jishin featured it one after another. It reached its peak in June of the same year when the June 29 issue of Shukan Asahi published a large feature by Etsuro Hiraizumi titled "The Bizarre Rumor of the 'Slit-Mouthed Woman' Terrifying Elementary and Junior High School Students Nationwide". In Himeji City, Hyogo Prefecture, a copycat dressed as Kuchisake-onna was arrested for violating the Swords and Firearms Control Law; in Koriyama City, Fukushima Prefecture, and Hiratsuka City, Kanagawa Prefecture, police cars were dispatched; and in Kushiro City, Hokkaido, and Niiza City, Saitama Prefecture, students were made to go home in groups. The rumor triggered real-world social responses. This is a rare case that embodies the yokai genesis of the mass media age, conquering the country in half a year through the linkage of cram schools and national magazines, rather than being picked up from simple beliefs or local lore of the Edo period. Since Toru Joko's "School Ghost Stories" academically organized it in 1990, it has been continuously read as a representative case study of modern yokai and urban legends.

At the edge of a schoolyard after classes, something with only half a body comes into view. It seemed far away, but in the next moment the sound of it striking the ground is close at hand. Teketeke is a modern school ghost story in which a body that is only an upper or lower half moves through schoolyards and school buildings, pursuing people. The image now most associated with Teketeke is a young woman who lost her lower body in a train accident and advances on her arms or elbows. Yet when Chiaki Konaka, who wrote the 1994 television drama *Yōkai Teketeke*, read school-ghost-story books from around 1993–94 while preparing it, they included both upper and lower halves that ran; they were often old women, and had no origin story. Before any biography of a single accident victim, there was a compact, easy-to-perform scene: half a body moving with an uncanny sound and speed. The name Teketeke is often explained as the sound of a body or arms striking a floor or the ground as it moves. Related names include Kagoshima's Patapata-san, Shiga's Kotokoto-san, Kanagawa's Katakata, and such names as Hijikake Babā, Hijiko-san, and Hijikake Onna. Stories in which part of a body moves with a repeating sound appear to have gathered under the name Teketeke through 1990s publishing and screen media. Its gender, age, missing half, place of appearance, speed, and manner of harm therefore vary with the school and generation telling the story. The name Teketeke becomes clearly visible in publications around 1993–94. Hints of an earlier presence survive in later recollections. A contribution submitted in 2004 recalled hearing a similar story in Okinawa around 1980, while a form passed from a teacher to students at one high school may reach back to the late 1980s or early 1990s. These accounts do not converge on a single station or accident. Half-bodied figures remembered in many places eventually came to be called by the same repeated sound. Local tellings are freer than the image familiar from film. In an account reported from Kobe Municipal Rokko Island High School in 2001, meeting Teketeke-san's gaze in a mirror brings pursuit. In a high-school account discussed in oral-literature research from 2022, Teketeke is a man's upper body, violently spinning its hands and neck, while pursuing people at the same speed as a human. Such contradictions are not errors; they are also part of the craft of school ghost stories, where a teller's voice, sound effects, and gestures produce fear and laughter at once. A backstory involving a young woman killed in a train accident was eventually overlaid on the half-bodied figure. Other additions included death within three days or 72 hours of an encounter, escape through a correct answer, and cutting with a sickle or saw. In particular, the rules that it comes to someone who has heard the tale within three days and poses a question are strongly associated with Kashima-san stories. Through their related images of a half body and railways, the two ghost stories exchanged names and rules. Koji Shiraishi's 2009 film *Teketeke* combined a postwar railway suicide in Kakogawa, Kashima Reiko, and death 72 hours after an encounter into a single origin narrative. The film's striking image of a woman strongly shaped what later came to feel characteristic of Teketeke. Beneath that image, however, the simple scene still moves: half a body chasing someone with a sound that seems to speak its name. Each move into a classroom, mirror, corridor, railway, film, or game gives that half body a new form and new rules.

The Seven-Fathom Wife is a giant female yokai from eastern Shimane (Izumo), the Oki Islands, and Hōki in Tottori. The term “fathom” (hiro) is a unit of length, and her height—or in some tales her neck—reaches seven hiro. She appears on mountain paths or along the shore, smiling at travelers, throwing stones, or miming laundry to bewilder people. Her look and behavior vary by locale, ranging from a beggar of striking beauty to a fearsome woman with blackened teeth and disheveled hair.

Amano-zako is a monstrous deity cited in an unspecified source quoted by the Edo natural history compendium Wakan Sansai Zue. Said to have taken shape from the fierce breath that Susanoo expelled from his body. Humanoid with beast-like traits, it has a high nose, long ears, and fangs. Its temper is violent; when defied, it rages and can hurl even mighty gods far away. It habitually contradicts things, linking it to the amanojaku, the contrary imp of Japanese lore.

A yokai depicted in Toriyama Sekien’s Hyakki Tsurezure Bukuro. Named after the document cart (fuguruma) used to carry letters, it is understood as the embodiment of attachment and passions accumulated in old love letters. Shown as a woman holding a scroll, it is a creative yokai inspired by Tsurezuregusa section 72 (“The Letters on the Cart”), widely interpreted as a tsukumogami in which the spirit of love letters fuses with that of an object.

Suzuhiko-hime was named and pictured by Toriyama Sekien in the final volume of Hyakki Tsurezure Bukuro, published in 1784. In the 1805 reprint held by the National Diet Library, she leans over a railing and offers an opened fan. Her head is layered with forms resembling small bells and their long cords, blurring the boundary between face and ritual implement. Despite the “hime” in her name, no record identifies her as the ghost of a particular princess, a deity enshrined at a shrine, or a female apparition known in local tradition. She is a yokai introduced in a single illustration by Sekien. Sekien’s caption recalls Ame-no-Uzume performing kagura before the rock cave in an effort to draw out the hidden deity. It is a brief, dreamlike allusion, not an origin tale for Suzuhiko-hime. In the rock-cave episode of the *Kojiki*, Ame-no-Uzume uses bamboo leaves and an overturned tub; kagura bells do not occur in the text. Suzuhiko-hime therefore cannot be identified as Ame-no-Uzume herself, her transformation, or a bell from the myth. Bell-carrying creatures also appear in earlier copies of Hyakki Yagyō Emaki. A mid-Edo manuscript in the National Diet Library depicts a birdlike figure holding a cluster of bells. Hidekazu Imai describes a related image as “a crane in miko dress holding bells”. The figure is not named Suzuhiko-hime, and it cannot be proved to be the same being as Sekien’s; the connection is a shared visual idea joining a miko, a bird, and bells. No primary source gives Suzuhiko-hime a fixed place of appearance, harmful act, benefit, personality, weakness, or method of defeat. Calling her broadly an implement yokai or tsukumogami does not license a personal tale in which a century-old bell changes from resentment. What can be firmly traced is a female figure incorporating the form of bells, an open fan, a caption longing for Ame-no-Uzume’s ancient performance, and an image later quoted by artists.
