Yokai Encyclopedia

This edition follows in close detail—while fixing the boundary between history and legend—how a single Bandō warrior became the uncanny "flying head" and then turned into a god who guards Edo. First, history and the uncanny must be separated. The revolt itself is conveyed by the near-contemporary Shōmonki, which records in classical Chinese the private feud beginning in 935, the subjugation of the Kantō provincial seats, the proclamation as New Emperor, and the death in battle in 940. But here there is no marvel of a flying head. The supernatural story of a head that would not rot, cried out, and flew appears only centuries later, in the Nanboku-chō-period Taiheiki, with anecdotal relays such as the Konjaku Monogatari-shū in between. It is in this later stratum of legend that Masakado is told as a "yokai." The story of the curse around his head mound is newer still. The dread transmitted at the Masakado Grave-Mound at Ōtemachi—"move it and it curses"—is a modern urban legend, layered onto events that occurred in the heart of the city in the Taishō and Shōwa eras: the deaths of those involved in building the Ministry of Finance's temporary office after the Great Kantō Earthquake, and the bulldozer accident during the Occupation. The factual events and the interpretation that attributes them to Masakado's curse must be carefully separated. The path of deification, on the other hand, reaches back into the medieval age. In the second year of Enkyō (1309), the Ji-sect holy man Shinkyō Shōnin, who attributed a plague to Masakado's curse, pacified the spirit and added it to the enshrined deities of Kanda Myōjin. This, like Michizane, is the textbook goryō belief of enshrining a raging vengeful spirit and turning it into a protecting god. The ups and downs—drawing the reverence of the people as the great tutelary of Edo, being removed from the enshrined deities as a traitor in the Meiji era, and being restored at the end of Shōwa—also reflect well the duality of the image of Masakado as a hero who rebelled against the throne. In later ages, the story of his daughter Princess Takiyasha commanding a giant skeleton won popularity in kabuki and popular fiction and was depicted in Utagawa Kuniyoshi's "The Old Palace at Sōma"; it should be noted that this is a derivative starring the daughter, not Masakado himself.

The Unique Position of the 'God of War'. While many deities in ancient Japanese mythology center around agriculture and nature, Takemikazuchi uniquely symbolizes 'war, swords, power, and conquest' as a rare male war god. This reflects Japan's complex history of unification through military force, symbolizing the justification and sanctification of military power in ancient national mythology. The Kuniyuzuri Myth ── Mythologization of Ancient Political History. The test of strength with Takeminakata mythologically represents the political integration of the central Yamato court and the regional Izumo and Suwa factions. The narrative of deciding matters through a legitimate trial of strength rather than sheer oppression served to secure religious justification during this integration process. The Ancestral God of Ancient Military Clans. The Futsu-no-Mitama sword became the core of worship for the Mononobe clan, the ancient military clan of Japan. Takemikazuchi concurrently supported the tutelary worship of both the Nakatomi/Fujiwara and Mononobe clans, making him a central figure in ancient Japanese religion, politics, and military affairs. The Two Great Shrines of Kashima and Katori. Kashima Shrine and Katori Shrine have historically formed the core of ancient military worship in the Kanto region. They served as the highest religious authorities in eastern Japan, standing alongside Ise and Izumo in the ancient Shinto shrine system. Earthquake Pacification. The Kaname-ishi (Keystone) belief at Kashima Shrine added a new attribute to Takemikazuchi as a guardian against earthquakes. This represents a significant evolution of an ancient mythological deity into a figure of early modern disaster folklore. Two Thousand Years of Sumo. The religious essence of sumo, persisting from ancient court rituals to the modern Grand Sumo, stems from Takemikazuchi's mythological origins. Sumo remains a rare example of a globalized sport retaining its ancient mythological roots. Takemikazuchi in the 21st Century. Today, he is revered as a guardian of martial artists, the ancestral god of sumo, and a protector against disasters. As Japanese martial arts spread globally, his worship garners international attention as the religious origin of these disciplines.

To read Takeminakata-no-Kami deeply, it is crucial not to treat the defeat in the *Kojiki* and the victory of Suwa Daimyojin as separate stories. In the Kuni-yuzuri myth, Takeminakata-no-Kami challenges Takemikazuchi-no-Kami to a test of strength, is defeated, and pursued to the Sea of Suwa. Kokugakuin cites a theory that interprets this scene as refusing to submit to the words of Takemikazuchi-no-Kami, and provoking another kind of contest through a test of strength. In other words, he is a god who did not obey the command of Heaven with words, but responded with the power of his body. The defeat is not a sign of this god's weakness, but evidence that he touched the order of the world with strength. Upon entering Suwa, that defeat shifts into a narrative of local integration. Suwa Taisha narrates that Takeminakata-no-Kami moved from Izumo to Suwa, building and ruling Shinano Province—Takeminakata-no-Kami moved from Izumo to Suwa. Kokugakuin introduces that the *Suwa Daimyojin Ekotoba* states he defeated the original god of Suwa, Moriya-no-Kami, and enshrined himself. Here, there is a composition where a god arriving from the central myth overlaps with the old gods and rituals of Suwa. Takeminakata-no-Kami is not merely a god who fled to Suwa. He collided with the land of Suwa itself, settled there, and changed into a god called by the name of the land. The divine character of Suwa Daimyojin is strong as a god of wind and water. Suwa Taisha explains Takeminakata-no-Kami as a god worshipped since ancient times for governing rain and wind, and as a tutelary god of agriculture, hunting, seafaring, and contests—tutelary god of agriculture, hunting, seafaring, and contests. These four are not disjointed. Rain and wind dictate rice farming; lakes and rivers support transportation and fishing; mountains serve as hunting grounds; and contests relate not only to warriors but to negotiations with nature. Takeminakata-no-Kami was worshipped as a god who reconnects fierce nature to human life. The Omiwatari makes this reconnection visible. According to Nagano Prefecture's explanation, when Lake Suwa completely freezes over, the ice cracks and forms high, mountain-like ridges of ice. This path is considered to be the trail left by the male god of the Kamisha, Takeminakata-no-Mikoto, visiting the female god of the Shimosha, Yasakatome-no-Mikoto—the path where the male god visited the female god. Furthermore, in the Miwatari ritual, the direction and shape of that path are used to divine crops, social conditions, and climate rainfall. The ice is not just a natural phenomenon; it is the movement of a god, becoming letters that read the future of the land. In the Onbashira Festival, Takeminakata-no-Kami's power manifests as the movement of trees and people. The explanation of the Onbashira Festival by Suwa Taisha states that it is a festival where sixteen massive fir trees are hauled and erected at the four corners of the four shrines' precincts, and that a sacred *nagikama* harboring a divine spirit is struck into them to recognize them as sacred trees—sacred nagikama said to harbor a divine spirit. The pillars are dragged purely by human strength, without the use of carts or rollers. Here, divine power is not a quiet interiority, but is renewed as a giant tree moving from the mountain to the village, the bodies of parishioners taking on danger, and the pillars standing at the four corners of the shrine. The god of Suwa is periodically re-erected. Beliefs about hunting and meat-eating also connect the fierceness of this god to daily life. Suwa Taisha recounts that even in eras when taking life was considered a sin, the people of Suwa received the divine talisman of O-Suwa-sama and were permitted to eat venison to survive—eating venison to survive. This is not so much a denial of Buddhist taboos as it is a mechanism where the god assumes the reality of a mountain province. Takeminakata-no-Kami is not a god who grants only clean fertility. He protects the life of the land by embracing hunts involving blood, sacrifices, the winter lake, and the danger of massive trees. Finally, the system of the Ohori, a living god (arahitogami), is crucial. Suwa City explains the Ohori as the yorishiro of Suwa Myojin, and the priest who stood at the apex of the Suwa shrines as a living god—the yorishiro and living god of Suwa Myojin. In the faith of Takeminakata-no-Kami, god does not solely exist in distant myth, but dwells in the human body, the system of the shrine, and the roles of festivals. The god defeated in the Kuni-yuzuri stands at the center of politics and ritual in Suwa through a living god. This inversion is the deepest allure of Takeminakata-no-Kami.

Takiyasha-hime is a sorceress shaped by stories of Nun Nyozō and Masakado’s surviving children who took vivid form in Santō Kyōden’s 1806 *Uto Yasukata Chūgiden*. In an 1836 kabuki dance, she disguises herself as the courtesan Kisaragi, while Kuniyoshi’s *Princess Takiyasha Calling up a Monstrous Skeleton Specter at the Old Palace in Soma* portrays her confronting Mitsukuni beside a gigantic skeleton.

The key to deeply understanding Takuhatachijihime lies in the fact that she is an "unspoken center". In the main text of the *Kojiki*, she only appears in the lineage explaining the transition from Ame-no-Oshihomimi to Ninigi-no-Mikoto, without speaking a word. Yet, for the protagonist of the Tenson Korin to shift from Ame-no-Oshihomimi to Ninigi, her existence is indispensable. Amaterasu's child does not descend directly; instead, the child born with Takagi-no-Kami's daughter, Yorozuhata-Toyoakitsushi-Hime descends. By this single sentence, the heavenly grandchild becomes a direct descendant of the sun goddess while simultaneously inheriting the blood of the creator god Takamimusubi. Therefore, defining her divinity merely with the word "mother" is too narrow. Ame-no-Oshihomimi is established as Amaterasu's child through the *ukehi* and chosen as the prince to rule Ashihara-no-Nakatsukuni. Meanwhile, Takagi-no-Kami issues commands alongside Amaterasu during the pacification, reinforcing heavenly political authority. Takuhatachijihime connects these two authorities through marriage and childbirth, integrating them into the person of Ninigi-no-Mikoto. She is not a god who commands from the front, but acts as the "loom of lineage" establishing the legitimacy of the Tenson Korin. The strong presence of weaving in her name resonates well with this role. The Kokugakuin University Deity Name Database explains that the "hata" in "Yorozuhata" refers to woven cloth, and that "hata" can also indicate weaving itself. Cloth is not a single thread. Only when the warp and weft intersect and repeat does it become a surface. Takuhatachijihime's function in myth is similar. She layers Amaterasu's lineage and Takamimusubi's lineage, heavenly commands and earthly fertility, the branching lineage of Ame-no-Honoakari and the royal lineage continuing to Ninigi, like a single piece of woven cloth. The abundance of variant names does not just blur her image; rather, it indicates the thickness of the myth's ancient layers. The database organizes the names appearing in the *Nihon Shoki*, such as Takuhatachijihime, Yorozuhatabime, and Amayorozutakuhatachihatahime, emphasizing that they all share "hata" (cloth/loom) in their names. *Taku* (paper mulberry) evokes the material of cloth, while *chiji* (thousand, thousand) suggests fine layering. Although Yorozuhata and Takuhatachiji may not share exactly the same etymology, the perception of the heavenly grandchild's mother as a "cloth-making woman" is universal. Furthermore, she simultaneously gives birth to two streams: Ame-no-Honoakari and Ninigi-no-Mikoto. The first part of the Tenson Korin in the *Kojiki* lists Ame-no-Honoakari-no-Mikoto. Next, Hikoho-no-Ninigi-no-Mikoto, two deities, and it is the latter who descends. This order suggests that the Tenson myth is not a monolith, but encompasses multiple clan memories and divine lineages. Because Takuhatachijihime is placed at this branching point, reading her is also reading how the Tenson Korin myth wove multiple lineages together. Her connection to the Amaterasu faith cannot be overlooked. The database notes that the *Kotai Jingu Gishikicho* describes Yorozuhata-Toyoakitsuhime being enshrined in the same hall as Amaterasu-Sume-Okami, and presents a theory viewing the deity of "Yorozuhata" as a weaving goddess connected to Amaterasu worship. This shows that the mother of the heavenly grandchild was not merely understood as a daughter of Takamimusubi, but was a deity who entered Amaterasu's ritual space. Just as the death of the weaving maiden brought darkness in the Heavenly Rock Cave myth, weaving and the order of the sun are deeply intertwined in Takamagahara. The rituals at Tsubaki Grand Shrine transfer this divinity to the present space of worship. The shrine explains that it enshrines the principal deity Sarutahiko-Okami, and in the *aidono* (companion shrine), it enshrines Ninigi-no-Mikoto and Takuhatachijihime-no-Mikoto. Sarutahiko is the god who guides the Tenson Korin, and Ninigi is the descending heavenly grandchild. When the mother goddess is enshrined beside them, the descent is seen not as a mere movement, but as an order passed down like cloth from mother to child, from heaven to earth. Takuhatachijihime has a quiet voice in the story, but she is the goddess who supports the very weave of the Tenson myth.

Reconstructed strictly from Sekien’s original image while preserving the absence of contemporaneous commentary. The figure is a gaunt woman whose body from the feet to the hips stretches like a serpent, extending from an alley up to the second-floor lattice of a townhouse to peer inside. Her actions are chiefly to startle, with no fixed malice. Regional proper names are uncertain, and later popular tales (brothels, satire, etc.) are treated as accretions. She is understood as a symbolic apparition that exploits nighttime quiet and architectural features, instilling unease in residents through her gaze.

This version turns to the events leading up to Tamamo-no-Mae’s unmasking and defeat. When the retired Emperor Toba’s illness grew at last grave, the onmyōji Abe no Yasunari (modeled on the historical Abe no Yasuchika), ordered to divine the cause, named Tamamo-no-Mae herself as its source. As Yasunari performed rites at court and cornered her, Tamamo-no-Mae could no longer hold her human shape; revealing her fox form, she fled eastward from the capital. The place she fled to was the Nasu Plain in Shimotsuke Province (the area around present-day Nasu in Tochigi Prefecture). To subdue the spirit-fox lurking in the wilds and harming people and livestock, the court dispatched warriors of the eastern provinces, Kazusa-no-suke Hirotsune and Miura-no-suke Yoshiaki. The warriors surrounded the plain, drove the fox out, and at last brought it down with arrows, so the tradition runs. The names of these warriors who slew Tamamo-no-Mae overlap with those of real Bandō warriors of the Genpei era—an intriguing case of legend and history told as one. In the story, Tamamo-no-Mae has usually been drawn as the very type of the “beauty who topples nations”—one who, through her beauty and wit, works her way to the summit of the realm and brings it down from within. Yet at the same time, once slain, she was enshrined in a small sanctuary and worshipped as a deity. Dreadful spirit-fox though she is, one cannot help being drawn to her. It is precisely this duality that keeps Tamamo-no-Mae from ending as a mere villain and makes her a figure beloved for ages.

A form rooted in the topographic legends of Kitayama Village. A fox is said to possess a person and display uncanny lightness, leaping across sheer cliffs. Variant tales pit it against serpents or yamabushi ascetics, so rivals and techniques differ by account. Anchored to cliff-line marks cited as physical proof, it serves to evoke the village boundary’s numinous authority and taboos. Ritual details and personal names are not preserved, and narratives remain general in outline.

What "fox seven, tanuki eight" means. "Foxes have seven transformations, tanuki have eight" is a familiar Japanese proverb. It says that tanuki surpass foxes by one degree of shapeshifting. An expanded saying, "fox seven, tanuki eight, otter nine, cat ten," orders animal magic into a ladder. Konjaku Monogatari-shu, volume 27, tale 22, where an aged tanuki becomes a demon, expresses the same idea: long-lived beasts awaken stronger powers. Named old tanuki such as Kincho, Danzaburo, Tasaburo, Shibaemon, and Inugami Gyobu may even become daimyojin. The eight-mat scrotum and Edo humor. The tanuki's scrotum is not biology but urban comedy. Edo goldbeaters were said to wrap a small amount of gold in tanuki skin and hammer it out to the size of eight tatami mats. Utagawa Kuniyoshi turned that joke into images of umbrellas, nets, rooms, shamisen, and sumo rings; Tsukioka Yoshitoshi moved toward the uncanny atmosphere of the Morinji kettle. Low-city caricature and temple ghost story together formed the early modern visual tanuki. Three Famous Tanuki and Three Great Legends. The two sets are often mixed up. Japan's Three Famous Tanuki are Danzaburo, Tasaburo, and Shibaemon. The Three Great Tanuki Legends are Inugami Gyobu, Bunbuku Chagama of Morinji, and the Shojoji tanuki-bayashi tale. The Awa Tanuki War, centered on Kincho and Rokuemon and mediated by Tasaburo, belongs to another stream made famous through kodan storytelling and film. The eight auspicious signs of Shigaraki tanuki. Shigaraki tanuki's eight auspicious signs read the statue's hat, eyes, smile, flask, account book, belly, money bag, and tail as blessings for business: avoiding misfortune, watching carefully, welcoming customers, having food and drink, keeping trust, staying calm, gaining wealth, and finishing well. In effect, postwar merchant ethics were projected onto a round, friendly tanuki body. Pom Poko, with tanuki driven out by development, shows the other side of the same postwar consumer society that put Shigaraki tanuki at shop doors. Why tanuki survive. Pom Poko from 1994 makes tanuki displaced local spirits under Tama New Town development and brings together famous tanuki, including Inugami Gyobu. The Eccentric Family from 2007 imagines Kyoto as a city where tanuki, humans, tengu, and foxes overlap. The tanuki endures because it changes with each period: Edo joke, Meiji image, postwar business charm, modern urban fantasy.

A classic case of tanuki-bayashi reported around Honjo in Edo. The sound layers like flute, drum, and shamisen, seeming to recede as you approach and shifting direction when you turn a corner. It often cuts off abruptly near waterways and moat edges. While common folk sometimes explained it as refraction and echoes caused by wind and terrain, people of the time also took it as the work of tanuki. Counted among the Seven Wonders of Honjo, it was frequently mentioned in sideshows and popular literature, with the names “Baka-bayashi” and “Tanuki-bayashi” used interchangeably. Notably, there are no accompanying sightings of a physical form, making it a sound-only apparition of high record value. Folklore warns that chasing it can leave you lost and wandering into the outskirts by dawn, so one should stop midway and cover the ears.

A half body glimpsed at the edge of a schoolyard closes the distance to the sound of "teke teke." This school ghost story, whose name became established in the 1990s, includes upper- and lower-body forms as well as old-woman and male variants. A later backstory of a young woman killed in a train accident was overlaid on it, and the 2009 film *Teketeke* linked Kakogawa, Kashima Reiko, and death after 72 hours to make today's familiar image especially vivid.

A form based on Toriyama Sekien’s illustration and accounts in war chronicles. It bears the will to hinder the Buddhist Law, pecking at temple timbers late at night as an omen of ill fortune. Tradition ties its origin to the vengeful spirit of Mononobe no Moriya, though its shape follows that of a woodpecker. In strange tales the sound comes first, a shadow is seen, and its true body is rarely caught. Folklorically it fuses bird-borne calamity lore with etiologies for temple damage.

This edition is not about a single seat on a particular sacred mountain, but a general treatise that thoroughly unravels "what a tengu is" from the history of its iconography and types. The individual traditions of each seat are left to the page of each great tengu. The form of the tengu is not uniform. The first type is the long-nosed tengu—ruddy face and high nose, clad in the ascetic's headcloth (tokin) and the suzukake robe, a feather fan in hand and one-toothed high clogs on the feet. The second is the crow tengu, with a crow's beak and wings, grasping a sword or a vajra staff. The third are the lesser tengu called leaf tengu and wood-chip tengu, held to be weak and numerous kin. Rather than a fixed classification, these reflect the breadth of the tengu image across eras and regions. The iconography shifted over time. The Heian-period tengu was first conceived as a bird like a black kite, and the image of the crow tengu retains that vestige. The long nose grows prominent only from the late Kamakura period; the Zegaibō Emaki depicts a scene in which a tengu that had disguised itself as a human has its nose lengthen as it returns to bird form. As for the origin of the long nose, there are theories that derive it from the high-nosed Jidō mask of gigaku and link the crow tengu to the Karura (Garuda) mask, and a view that sees the long nose as an iconographic vestige of a bird's beak—but none can be called settled doctrine. It was overlaid with the god Sarutahiko, described in the Nihon Shoki as having a nose seven hand-spans long, and the custom arose of using a tengu mask for the role of Sarutahiko in festivals. The tengu's dual nature is rooted in the Buddhist notion of the way of the tengu. Because it studies the Buddhist path it does not fall into hell, and because it handles heterodox arts it cannot reach paradise either—an intermediate state, and the one who falls there was held to be the arrogant monk. The Tengu Zōshi depicts this notion as satire of the monks of the seven great temples, yet Chigiri Kōsai too warns that the simplification "only arrogant monks become tengu" goes too far. Demon though it is, once subdued it turns to guardianship, and it was held that if a Shugendō practitioner recites the Tengu Sutra he may summon the tengu of the various provinces to grant his wishes—this amplitude between guardian and demon is the very core of the tengu. The certain medieval source for the grouping called the "Eight Great Tengu" lies in the libretto of the Muromachi-period Noh play Kurama Tengu. The passage in which the great tengu calls up the tengu of the provinces he commands in geographical order—"In Tsukushi, Buzenbō of Hiko-san; in the four provinces of Shikoku, Sagamibō of Shiramine; Hōkibō of Ōyama; Saburō of Iizuna… the host of Zenki of Ōmine, Takama of Katsuragi"—shows that the Eight Great Tengu were rooted in medieval belief and performing arts, not an Edo invention. Still, the composition wavers by source, with a variant that adds Hōkibō of Ishizuchi-san; it is no fixed roster.

Hōshōbō of Mount Hiei is a great tengu who ranges the peaks of Hiei, where the capital meets the lake, dwelling between cedar and cypress crowns and the sea of clouds. Cloaked in the ridge winds of the Sannō shrines, he bears crow’s wings and a feather fan like a yamabushi’s ritual tool, said to appear at midnight with the lingering echo of a conch. His face is severe, ruddy with a high nose, eyes keen as if seeing through the ages. Yet his bearing recalls a monk, and the folds of his robes carry the scent of sutras. Named among the forty‑eight tengu of the Tengu Sutra since olden times, he guards Enryakuji’s teachings and the mountain’s vital currents, and in the era of the monastery’s ascendancy was said to guide and correct the conduct of its students both openly and unseen. Hōshōbō is not merely masterful in martial arts but cuts through the frayed edges of words to reveal a thing’s true nature. When a seeker loses their way, he thickens the mist and erases the markers, or lures an unsettled heart into the shadows of halls and pagodas—not to mislead, but to teach that wavering within is what leads one astray. When that is realized, the fog clears at once and Hiei’s ridgeline turns blade‑bright. Conversely, those who climb seeking fame and profit or who slight the Sannō deities are driven off by winds that make leaves into blades, never again permitted a frivolous ascent. Elders of Hiei whisper that Hōshōbō entrusts the essence of Lotus and Esoteric teachings to the wind, marshals flocks of birds to the cadence of chanting, and governs prayers for rain and for clearing skies. If Enryakuji’s bell tolls strangely, it is a sign of his feather fan stirring on the heights, and there were nights when sutra characters trembled across the lake’s ripples. At times he appears at a young ascetic’s bedside, delivering a single thunderous admonition that severs the root of delusion, leaving at dawn a single drop of white dew—medicine when diligence holds, poison when sloth prevails. He most abhors when urban rumors and power struggles spill onto the mountain, and bears an art that stills the blades of speech. When people wound each other with slander, a downslope wind rattles the town eaves and falsehoods collapse under their own weight; thus those who guard their tongues gain his protection. Yet he shows no mercy to those who hide pride behind practice: he lightens their footsteps until they lose the ground and wander forbidden paths of empty theory, and only when they admit their fault do their feet return to earth. On nights when the bush warbler in Hiei’s forest falls suddenly silent and distant thunder rings pure, Hōshōbō is near. If pilgrims bare their heads and pay full respect before the Sannō, the ridge wind softens and a single shaft of light breaks the clouds. This is called the Return of Hōshō—a sign that prayers in the mountain have been rightly answered. Hōshōbō is both guardian of the mountain and tester of the teaching; fear becomes reverence, and reverence opens the way. Only those who grasp this find his wings a sheltering shade for the road.

Kakukai-bō of Yokogawa is said to be a tengu variant who turned from human monk to winged guardian of the Dharma from the late Heian into the early Kamakura era. Once a virtuous priest of deep Shingon lineage, he ran himself ragged settling mountain disputes until he grasped a boundary no worldly rule could protect, becoming a winged keeper of sacred law. In Kōya’s inner precincts, they tell how one night a gale whirled through a hall and the middle gate shuddered, then its doors shed their hinges, unfurled as twin feathers, and split the black clouds to fly off. Those doors became Kakukai-bō’s wings. Ever since, he appears with the comings and goings at temple gates, raising a fierce wind before those who disturb the rule and presenting a single line of precept. He resembles a karasu-tengu, yet his face keeps the gaunt trace of an old monk and his long nose curves like a mountain ridge. His feathered robe echoes priestly vestments, layered in cinnabar and ink, its cuffs frayed like the edges of ancient sutras. He carries a feather fan akin to a monk’s staff, and when he sweeps it, seed-syllables rise like chaff off paper, racing along the ground as ropes of warding. He speaks sparingly, but his words hang like a bell’s aftertone, stopping the feet of those who have strayed. He guards the mountain’s thresholds—the shrine and temple gates, the bends of approach paths, the joins of ridge and valley—where human law brushes mountain law, serving as their mediator. When a practitioner keeps purity, he lets fall a single white feather from the cloudbreak as a sign of safe passage. But if pride sprouts, the vigil lamp flickers once and a cold wind runs down the back. Feeling this thrice, one must follow his guidance to descend the mountain or doff one’s robe and return to first intent. He also teaches the ‘Doctrine of Drying’: to clear the heart, remove needless damp—a metaphor tied on the mountain to drying beans for stores and keeping offerings pure. Though unproven, it stands as a sign of turning the mountain’s rigor into daily sustenance. Late at night when mist pools in the valleys, he patrols with a train of crows. They are his eyes and ears, giving short signals to those swayed by rumor. Read rightly, the signs lead one off the wandering path, read wrongly, one circles the same ground three times. This is called Kakukai’s Rounds, and on the third turn, if one straightens the crook in the heart, the eastern ridge pales and the path opens naturally to the main gate.

The tengu do not stop at the Eight Great Tengu. Each of the sacred mountains of the provinces was believed to have its own great tengu, and the early-modern esoteric prayer-scripture the Tengu Sutra lists their representatives as forty-eight seats—the "Forty-Eight Tengu." This edition is an overview that surveys the full roster and the provenance of the scripture itself. The Tengu Sutra is an esoteric, Shugendō-lineage prayer text said to have been compiled in the Edo period. It is not an orthodox sutra of the Buddhist canon, but belongs to the lineage of incantation-scriptures that a yamabushi recites in his devotions to summon (invoke the descent of) the tengu of the sacred mountains of the provinces, borrowing their numinous power to pray for the dispelling of demons, the subjugation of enemies, and the fulfillment of all wishes. The text begins with the chant "Homage to the great tengu and the small tengu," lists the names of the various tengu, then gives the total of the tengu as "one hundred twenty-five thousand five hundred in all," and closes with the mantra "On aromaya tengusumanki sowaka." This "one hundred twenty-five thousand five hundred" is not a real count but a symbolic number representing innumerable tengu, and the forty-eight seats named by their proper names are positioned as the representatives among them. As for the transmission of the manuscripts and printed editions of the Tengu Sutra, there are philological studies such as Takahashi Sei's "The Tengu Sutra: Its Present State and Whereabouts" (2016), and it is difficult to fix the date of compilation strictly to a single point. The roster of the Forty-Eight Tengu runs in the form of "bō" titles (sacred-mountain name + the name of the bō). The opening begins with the great tengu of the Kinai—Atago-san Tarōbō, Hira-san Jirōbō, Kurama-san Sōjōbō—and is followed by the tengu of the Shugendō sacred mountains across the land such as Fuji, Nikkō, Haguro, Akiba, Hikosan, and Ishizuchi. Below are listed all forty-eight seats, collated against two confirmable lines of sources, together with the bō title, sacred mountain, and province (present-day prefecture). ★ marks the Eight Great Tengu that have their own pages in this encyclopedia. 1. ★Atago-san Tarōbō (Mt.

First, the bō titles (the names of each seat) agree across multiple sources and are reliable, but errors mixed into secondary web information mar the identification of the province and prefecture. For instance, Mt. Shibi is in Kagoshima Prefecture (Satsuma), and "Hyūga" is the old province name of Miyazaki Prefecture—misattributions confusing these with places in the Kantō or Tōhoku are in circulation. In this roster, "tentatively identified" is appended to seats whose identification has latitude, and "location unknown" to seats whose whereabouts cannot be confirmed among the sources. Second, there are seats such as Amanoiwafune Dantokubō, Nara Ōku Sugisakabō, and Itatōyama Tondonbō whose location multiple sources hold to be "unknown," and no place name has been forced upon these. Third, there is variation between the bō titles of the Eight Great Tengu and the wording of the Tengu Sutra text. For example, the Ōyama Hōkibō of the Eight Great Tengu appears in the text as "Hōki Daisen Seikōbō," and Ōmine Zenkibō appears in the "Nachi Takimoto Zenkibō" / "Kumano Ōmine Kikujōbō" line of wording. The Eight Great Tengu are commonly explained as eight representative seats drawn from among these forty-eight, but the bō titles do not agree word for word. The framework of the Forty-Eight Tengu shows most plainly that the tengu was not a solitary yokai but a deity of mountain worship seated throughout the sacred mountains of the whole country. Chigiri Kōsai, who compiled the study of tengu, likewise organized these mountain tengu into a single system. Each seat of the Eight Great Tengu (★) is treated in detail on its own page, but they too are simply the especially high peaks within this sea of one hundred twenty-five thousand five hundred tengu.

Tengu-tsubute is told as a formless anomaly whose cause has been variously ascribed to tengu, foxes, or divine intent. Stones fly from all directions though no thrower is seen, impacts and sounds are real yet no stones are found, no marks remain, and the events repeat at set hours. Cases are recorded widely from Kaga, Kanazawa, and Edo in urban quarters to shrine precincts, and some reports note that crowds of onlookers or official patrols led to its quieting. Morally it serves as a warning against misconduct and as an omen of crop failure or illness, and older records link it with thunder as stones cast by Tenjin. Folklore studies connect it conceptually to stone-throwing rites, mass petitions, and indochi stone fights, understanding it as an expression of a supernatural will.

This version explores why the Tenko is spoken of as “a yōkai yet near to a god,” and where it truly stands. Of the four grades of fox, only the lowest — the Yako — appears before people in a body of flesh to bewitch them. The higher its rank, the more a fox becomes a formless, spiritual presence, and at the summit, the Tenko, it is described less by any shape than by its very workings: seeing for a thousand leagues, communing with the will of heaven. As Yanagita Kunio and Nakamura Teiri have laid out, the Tenko is the utmost extreme of the senko, the spirit fox that has lived a thousand years and accumulated virtue. In neither deceiving people nor leading them astray, but watching over them from above, the Tenko stands at the opposite pole from the Yako. It was this transcendence that drew the Tenko up into religious faith. Just as Dakiniten is attended by a white fox and Izuna Gongen rides one in the guise of a karasu-tengu, the highest fox is enshrined as a familiar of the gods and buddhas, or as a deity in its own right. The power to which warlords prayed for victory, and to which villagers pressed their palms in hope of fire prevention and good fortune, was in the end the power of this fox in communion with heaven. One thing to be wary of is confusing Tenko with tengu. Because an old usage read “shooting star” as amatsu-kitsune, the two have long been mistaken for one another , yet the Tenko is, properly, a fox that has raised its spiritual rank to the utmost limit — a being of a wholly different lineage from the mountain-ascetic tengu.

Based on Toriyama Sekien’s “Tesso” motif, it appears as a giant rat draped in robe-like shadows, with red eyes and teeth said to be iron-hard. Its origin lies in the vengeful spirit tale of Raigō tied to disputes over the ordination platform at Onjōji, where rivalry between Enryakuji’s Sannō faction and the Miidera side was cast into story and overlapped with real rat damage to temple sutras and treasures. Names vary by period and source, with “Raigō Nezumi” and “Miidera Nezumi” coexisting. Medieval war tales exaggerate its numbers into a calamity of swarming rats, while from early modern times it links to shrine legends of pacification and blessings. Chronologies in records do not always align and the tale is highly narrative, yet shrine and temple names, linked verse, and oral lore support a core tradition. In some regions, extermination stories feature a great cat of Mount Hiei or guardian deities, reflecting the boundary-conscious rivalry between two religious centers.

An iconographic reading of the Dōjōji bell as depicted in Toriyama Sekien’s Konjaku Hyakki Shūi. While a note alludes to a variant in which the woman, transformed into a serpent, coils around the bell hiding Anchin and heats it until it melts into scalding liquid, hearsay also holds that the bell itself survived in historical record. Its “yokai nature” here is less an ensouled object than a visualization of folk belief in obsession possessing a vessel and causing anomalies. It represents Edo-period reception where Noh, sekkyō, and engi traditions intermingle.

A waterside bake-danuki tale tied to the Aoiishise shallows of the Yoshino River in Awa Province. At midnight, when a boat moors, a colossal pipe is offered and an enormous amount of shredded tobacco is demanded. The motif of a shape that begs tobacco, found across Japan, merges here with Awa’s tanuki beliefs, forming a folk pattern in which lack of offerings brings curse or calamity. The quantity is said to reach ten forty-momme bags—impossible to carry—serving as a practical warning against overnight mooring at the rapids. If the pipe is fully packed, it departs without harm, reflecting a folk sense of boundaries, bargains, and payment. Its form is rarely described, often only a giant hand and pipe are perceived. Boats are threatened by sounds and waves, sometimes said to sink, turning fear of careless conduct aboard and the night waters into story. It warns against excessive curiosity and negligence while transmitting the geographic dangers of the shallows.

The Kesa-bō of Igusa is told as a kappa belonging to the local waters, marked by a monkly appearance symbolized by a priest’s kesa stole. Its pranks cause real harm, such as obstructing passage or adding weight, and at times tie into sacrificial notions surrounding the intestines. The listing of neighboring kappa names typifies kappa groups distributed along each water system, accompanied by ideas of mutual visits and marriage ties. The setting centers on the channels near Ochiai Bridge, where nighttime travel was shunned. Later records sometimes confuse it with examples from Miyagi Prefecture, but locally the tradition is firmly fixed under the name Igusa.

A portrayal based on the tale of the Guardian Crane at Morinji Temple in Jōshū. The ever-boiling teakettle symbolizes almsgiving and joy in the Dharma, and sharing tea with monks and visitors is understood as spreading virtue. The guardian is a long-lived tanuki who lives among humans while bound by Buddhist ties. When its true nature is exposed, it leaves the temple, but at parting uses illusion to show scenes of ancient battles and Buddhist rites, teaching people impermanence and the virtue of the Law. Later, this tradition split into two strands: one reshaped into the folktale Bunbuku Chagama with showy acrobatics, and one remaining within the temple’s origin legend. Locally, it is told in connection with the temple’s treasured kettle, influenced by tanuki worship, storytelling, and essays, yet its core reduces to two points: the inexhaustible hot water and the departing wise tanuki.

A recorded marvel revered and feared as the very phenomenon of an ancient chinkapin that shed no leaves. Understood less as a personified will and more as the ambience of the land or the work of a tree spirit, it is told alongside other Honjo Seven Mysteries such as Okehazubori and the Foot-Washing Mansion as an enigma that reveals no cause. Named in Mimibukuro and in local gazetteers and collections of strange tales, it is not remembered for direct harm but for an uncanny presence that keeps people away. It aligns with tree veneration and the notion of household guardian trees, with hyperbole like needing no sweeping of fallen leaves to emphasize the marvel. The identification of the actual tree is debated and unconfirmed.
