Kama-itachi is a name for a wind-borne anomaly found in Edo-period art, essays, and oral lore, referring both to the phenomenon and its alleged agent. It is tied to whirlwinds and chill gusts in northern and mountainous regions, noted for razor-like lacerations when one stumbles on the road, delayed pain or bleeding, and frequent injuries to the legs. Its true nature varies across sources: invisible minor spirits, beasts riding the wind, or acts of deities coexist as explanations. In Shin’etsu it is said to strike those who break calendrical taboos, and in Hida a three-stage action is told. In parts of Chubu and Kinki, the whirlwind itself is called kama-itachi, while Edo essays report beast tracks left after a dust devil. Under regional aliases like Tosa’s “Field Sickle,” funerary tools turned uncanny are blamed for similar wounds. In haiku it settled as a winter season word and a sign of wind-borne calamity. This version limits itself to attested sources, avoids overlinking to specific places or persons, and presents regional types side by side.

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.

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.

An image of the Moon Rabbit grounded in Japanese iconography. From Asuka-period examples onward, the rabbit within the lunar disk was paired with the solar crow in medieval Buddhist painting and received as a bearer of celestial phenomena. In early modern times, depictions of a rabbit using a Chinese-style mortar and pestle spread through books and prints, and by the eighteenth century the mortar shifted into a characteristically Japanese hourglass shape. The rabbit came to be understood not as compounding an elixir of immortality but as pounding mochi, linking it through wordplay to moon viewing and full-moon festivals. In lore, a self‑sacrificing rabbit ascends to the moon by Indra’s grace, with the lunar shadows and smoke-like markings read as its traces. In folk practice, people gazed at the moon seeking the rabbit’s silhouette, and the theme persisted in moon‑vigil gatherings and storytelling, overlapping with other celestial yokai and lunar deities.

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 is the interpretation of the chimera clad in black clouds, shot down by Minamoto no Yorimasa. In this version, the Nue is not simply a physical beast of prey; it functions as a kind of "sorcerous cyborg," the incarnate coagulation of the "indefinable anxiety" and "political pathology" that gripped the aristocratic society of its time. From the perspective of modern yōkai studies and Onmyōdō (the Way of Yin and Yang), the animals comprising the Nue are said to symbolize the "four corners (boundaries)" in the directional system of the Chinese zodiac. Specifically, the monkey represents the "Southwest (Hitsujisaru)," the tiger represents the demon gate of the "Northeast (Ushitora)," and the snake represents the "Southeast (Tatsumi)." While the cardinal directions represent a world of stable order, the four corners are considered unstable boundaries leading to the otherworld. The Nue is the embodiment of chaos, a patchwork assembled from the "outside of order." Even more fascinating is that the beasts corresponding to the final direction, the "Northwest (Inui)"—namely, the "boar (Inoshishi)" and the "dog (Inu)"—are absent from the creature's physical body. However, in the *Tale of the Heike*, the retainer who rushed to the Nue shot down by Yorimasa and thrust the finishing blade into it was named "Ino Hayata" (whose name contains the character for boar). Some interpret this as an exceptionally exquisite symbolism: it is only through the addition of the missing final direction (the boar) that the sorcerous spatial construct of the Nue is completed and thereby annihilated. The means by which the Nue plunged the Emperor into sickness was not direct violence, but rather the pollution of "ki" (life force) caused by its scream-like "hyo-hyo" cries and the visual pressure of the black clouds. The Nue is essentially one of Japan's greatest political monsters—a manifestation of the waning royal authority and the turbulent atmosphere of the late Heian period, an era when the samurai rose to power and the world of the aristocracy began to crumble, taking the physical form of a "synthetic beast."

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.

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.

A work by Toriyama Sekien that riffs on a transformation tale in the Book of Rites, caricaturing the principle by which a sea shell assumes a demonic aspect. Depicted as a turban shell with a human arm and an eye on its lid, it serves less as a harmful monster than as a visualization of ideas about metamorphosis and things-turned-spirits. It aligns with shell personifications in early modern Hyakki Yagyo paintings, conveying a sensibility that sees numinous presence in coastal nature. Later erotic ghost anecdotes are largely inventions and should be understood apart from this prototype.

Seiryū is not a dragon standing alone, but a numinous beast that takes on meaning only within the directional system of the Four Symbols. This edition traces its astronomical origin and its reception in Japan. The origin lies in the heavens. Chinese astronomy distributed the twenty-eight lunar mansions across the four quarters, seven to each, and likened the chain of stars of the seven eastern mansions (Horn, Neck, Root, Room, Heart, Tail, Winnowing Basket) to a single dragon. This is Seiryū. The Huainanzi's "Treatise on the Patterns of Heaven" makes the emperor of the east Taihao and its beast the Azure Dragon, assigning it to the Wood phase and spring, weaving the five directions, five colors, five seasons, and Five Phases into a single cosmology. The "Treatise on the Celestial Offices" of the Records of the Grand Historian likewise makes the eastern palace of heaven the Azure Dragon, binding constellation to numinous beast. The azure of Seiryū is the color of the Wood phase, figuring the rising life-force of spring in the east. Its deep layer is engraved in relics. The lacquer garment chest from the tomb of Marquis Yi of Zeng (c. 433 BCE), the oldest astronomical relic to bear the names of the twenty-eight mansions, depicts the Azure Dragon and White Tiger as a pair. In the Han period, the patterns of the Four Symbols adorned roof tiles, bronze mirrors, and pictorial stones, becoming emblems that warded off evil and summoned fortune. In Japan, the Four Symbols were received as a theory of astronomy, tomb-building, and capital planning. The Four Symbols' banners of the first year of Taihō (701) in the Shoku Nihongi are the certain literary first appearance, and in iconography the Azure Dragon on the eastern wall of the Kitora Tomb in Asuka survives as one wing of a four-direction-complete mural of the Four Symbols. Thus Seiryū was placed between star and terrain, as the guardian beast that governs the east and brings the spring.

Based on the account in Kabhiko, it is framed as a small dragon-serpent linked to a manor in Kyoto’s Higashiyama. It resembles a dragon yet is not deified, lurking beneath the soil and under stones, and manifests alongside ominous signs such as withering garden trees and cracked garden stones. Its defining trait is an extreme toxicity said to kill within moments of a bite, echoing ancient lore and fear of deadly vipers. Sightings are rare, with tales in which swarms of strange snakes appear first, and at the end the Seven-Step Viper reveals itself as the true body. It bears four legs, upright ears, and red scales edged in gold—colors read as both auspicious and baleful—and is often taken as a sign of a household’s decline or a disturbance in the land. In folk practice it is tied to neglected stones on mountain skirts and old gardens, and locals would pray before moving stones to avert calamity.

The origins of the Shojo lie in two lineages of lore from Chinese classics. ① The "Speaking Beast" Lineage — In the "Quli" section of the "Book of Rites", it is stated: "The parrot can speak, but it still belongs to the birds; the shojo can speak, but it still belongs to the beasts" (a moralistic quote meaning that even if it understands human speech, it does not transcend the realm of beasts). The "Erya" describes it as "small and fond of howling," while the "Classic of Mountains and Seas" states: "On Mount Zhaoyao, there is a beast whose shape resembles a macaque with white ears; it crouches to walk and runs like a human. Its name is xingxing (=shojo), and eating it makes one a good runner." ② The "Beast Fond of Wine and Blood" Lineage — The "Commentary on the Water Classic" notes that the shojo of Pingdao County in Jiaozhi "looks like a yellow dog or a badger, has a human face with regular features, is good at talking with people, and its voice is as beautiful as a fine woman's." The "Lüshi Chunqiu" considers "the lips of the shojo" a great delicacy, while Li Shizhen's "Bencao Gangmu" (1596) details it as a creature from Jiaozhi (modern-day northern Vietnam) with a human face, beast's body, yellow hair, and a fondness for wine. The modern associations with the orangutan or palm civet are later identifications; academically, the classical shojo is best understood not as a real animal but as a composite image of a legendary sacred beast. Its introduction to Japan occurred before the Middle Ages via Chinese texts and Buddhist scriptures. The "Wamyō Ruijushō" (10th century) introduced it as a "speaking beast" citing the "Erya", and it appeared indirectly in the "Konjaku Monogatarishu". Terajima Ryoan's "Wakan Sansai Zue" (1712) was groundbreaking — it explicitly pointed out that "yellow hair is correct, and the 'red hair' theory circulating in Japan is mistaken." Nevertheless, the image of "red hair" became entrenched in Japan due to the influence of Noh theater, a divergence that forms an interesting point of debate in art history and folklore. The uniquely Japanese image of red hair flowed backward from Noh costumes and became fixed. The Noh play "Shojo" (established in the Muromachi period, author unknown) is a current repertoire piece for all five schools, and is one of the most beloved plays, serving as a fifth-group play and kiri-Noh. Set at the Xunyang River in Tang China, it tells the story of Kofu, a filial son who sells wine in the village of Yangzi, and succeeds after a dream revelation. A red-faced customer who frequents Kofu's shop daily introduces himself as the "Shojo who lives in the sea." Waiting at the Xunyang River on a moonlit night, the Shojo appears, drinks wine, performs a dance, and bestows an "inexhaustible wine jar" — a celebratory theme of rewarding filial piety. The play fuses sources like the "Tang Guo Shi Bu", the "Chuci" (The Fisherman), and Li Bai's poem about the Xunyang River. The costume features a red wig, red Karaori robe, scarlet divided skirts, and a dedicated Shojo mask (painted red, with a smiling mouth and eyes). Its highlight is the "chu-no-mai" dance, or the special performance (kogaki) "midare" — a highly advanced technique where the performer glides over the water with erratic, flowing steps. In the Edo period, because Jurojin and Fukurokuju of the Seven Lucky Gods were identical, a variant Seven Lucky Gods circulated where Jurojin was replaced by the Shojo. Kita Sadakichi's "Study of the Gods of Fortune" (1920) cites primary sources like the "Genroku Gorui Setsuyo", making it academically robust. This variant form also appears in treasure ship paintings by Hokusai, Kuniyoshi, and Yoshitoshi. A "Shojo" giant doll festival has been passed down since the mid-Edo period in Arimatsu and Tokai City in Nagoya. Spreading along the old Tokaido highway, it already appeared in the "Narumi Festival Picture" of 1779. Giant red Shojo dolls chase children, and being tapped by one is believed to ward off summer diseases and epidemics. There are also local legends across the country, such as oral traditions of small Shojo appearing at sea in Toyama, or a ship-ghost variant demanding "give me a barrel" in Yamaguchi. "Shojohi" (Shojo scarlet) is a deep crimson color originating from the red costumes of the Noh play "Shojo". Though popularly called the "color of Shojo's blood," the actual dye was cochineal/kermes, and the "Shojo's blood" is merely a myth. Scarlet woolen cloth imported via the Nanban trade in the late Muromachi to early Edo periods was highly prized by Sengoku warlords for their surcoats. During the Edo period, it was such a rare luxury that the shogunate would confiscate it from merchants, making it a symbol of martial prowess and authority. In modern times, it appeared in Hayao Miyazaki's "Princess Mononoke" (1997) as the "sages of the forest," trying to replant trees to restore the forest but unable to keep up with humans, begging San to "let us eat humans, we want human strength". The red image of the Shojo is also inherited in biological names like the fruit fly (Drosophila, named for its attraction to alcohol), the Shojo dragonfly, and the Shojo-bakama flower.
