伝説 Tengu
Tengu
What Is a Tengu? An Overview of Types and Iconography
Mountain & Wilderness SpiritsKyoto, Shiga, and Wakayama Prefectures (the seats of the great tengu on the various sacred mountains)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.

伝説 Shiramine Sagamibō
Shiramine Sagamibō
The Tengu Who Guards the Mausoleum of Sutoku — Shiramine Sagamibō
Mountain & Wilderness SpiritsShiramine, Sanuki Province (Sakaide, Kagawa)Shiramine Sagamibō is, among the Eight Great Tengu, the tengu most firmly bound to a single person—the Retired Emperor Sutoku. His image cannot stand apart from the story of Sutoku's vengeful spirit. The Retired Emperor Sutoku, defeated in the Hōgen Rebellion (1156), was exiled to Sanuki and died in the second year of Chōkan (1164) without ever being permitted to return to the capital. At his place of exile he copied out the five Mahāyāna sutras and sent them to the capital, but, suspected of a curse, had them flung back at him; in fury he swore an oath written in blood and is said to have become, while still living, a great tengu and a great demon (daimaen). Sagamibō guards the Shiramine mausoleum of this Sutoku, whom Yoritomo called "the greatest tengu in Japan." Shiramine-ji is the eighty-first station of the eighty-eight temples of Shikoku, the Shiramine mausoleum is the only imperial tomb in Shikoku, and beside it stands the Tonshō-ji-den, which enshrines the spirit of Sutoku-in. It was literature that made Sagamibō immortal. Its original source is the mid-Kamakura Senjūshō, attributed to Saigyō, whose "On the New Retired Emperor's Tomb at Shiramine" carries a tale of Saigyō mourning Sutoku's tomb at Shiramine. The Noh play Matsuyama Tengu, which dramatized it, takes Sutoku-in as the shite and Saigyō as the waki, and depicts Sagamibō as a tengu attending Sutoku. Further, the "Shiramine" of Ueda Akinari's Ugetsu Monogatari is a story in which Saigyō mourns Sutoku's spirit at the Shiramine mausoleum and converses with the wrathful Sutoku-in; Sagamibō became the being running through this lineage since the Senjūshō. The vengeful spirit and the tengu who stays beside it—the relation of Sutoku and Sagamibō is a rare point where the faith in goryō (vengeful spirits) and the faith in tengu meet. There are two theories on Sagamibō's origin: that it derives from Sagami Ajari Shōson, who sided with Sutoku in the Hōgen Monogatari, and that he was a tengu who came from Mt. Ōyama in Sagami. The latter forms a pair with the seat-transfer tradition arranged by Chigiri Kōsai—that the Sagamibō of Ōyama, in devotion to Sutoku, removed to Sanuki, and Hōkibō entered the vacant Sagami Ōyama. Either way, Shiramine Sagamibō sits at the western end of the Eight Great Tengu, transmitted at Shiramine in Sanuki as the tengu who keeps guarding the soul of Sutoku, one of Japan's three great vengeful spirits.

名妖 Emperor Sutoku
Emperor Sutoku
Emperor Sutoku, the Vengeful Spirit Exiled to Sanuki
Spirits & GhostsSakaide (Kagawa Prefecture) and Kyoto (place of exile and death; shrines of pacification)This edition follows in close detail—discerning the boundary between history and the legend that runs from the Hōgen Monogatari onward—how a single deposed emperor turned into the Great Tengu and Great Demon-Bond called the greatest in Japanese history. First, the history must be grasped. Sutoku's misfortune lay in the political exclusion of being shunned by the cloistered emperor Toba as an "uncle-child" and being made to abdicate without ever holding the power of cloistered rule. After the early death of Emperor Konoe, that his younger brother Go-Shirakawa, rather than his own son Prince Shigehito, was set up became the trigger for the Hōgen Rebellion (1156). On the defeated Sutoku's side, Minamoto no Tameyoshi and Taira no Tadamasa were put to public execution for the first time in roughly four hundred years, and Sutoku himself was exiled to Sanuki. Up to here it is history grounded in records. The uncanny is born beyond that, in the stratum of legend. Both the curse said to have been written in blood—"I shall become the Great Demon-Bond"—after biting off his tongue, and the figure of him turning into a tengu with nails and hair grown long, are stories transmitted not by contemporary records but by the Kamakura-period Hōgen Monogatari. Yet this legend spread with great persuasive force, and the great fires, forceful appeals, and upheavals that struck the capital from the Angen years onward—indeed, the Jishō-Juei War leading to the fall of the Taira—came to be read as Sutoku's curse. The events themselves are history; the interpretation that ascribes them to Sutoku's rancor is goryō belief—the two must be seen as sharply distinct. What fixed Sutoku's tengu image was literature. "Unkei Miraiki," book twenty-seven of the Taiheiki, depicts Sutoku as a demon-king ruling the throngs of tengu and demon-bonds, and in the early-modern era "Shiramine" in Ueda Akinari's Ugetsu Monogatari gave vivid form to Sutoku's vengeful spirit confronting Saigyō—not as a long-nosed tengu but as a golden kite. The image of Sutoku told of as "the foremost Great Tengu of Japan" and "the greatest vengeful spirit in Japanese history" stands upon this accumulation of literature. What deserves attention is that his pacification reached even into the modern era. In the first year of Meiji (1868), the Meiji government welcomed Sutoku's divine spirit, resting in Sanuki, to the capital and enshrined it at Shiramine Jingū. That at the outset of a new reign they still feared the curse of a deposed emperor seven hundred years past tells how deep-rooted the dread of Sutoku's vengeful spirit was. A poet who left a famous verse in the Hyakunin Isshu, and a great demon-king who curses the throne—this very gulf is what pushed Retired Emperor Sutoku to the apex of goryō belief.

稀少 Aobōzu (Blue Monk)
ah-oh-BOH-zoo
Aobōzu of Traditional Iconography and Provincial Tales
General ClassificationsVarious regions (Wakayama, Fukushima, Gifu, Hiroshima, Shizuoka, Nagano, Okayama, Yamaguchi, Kagawa, etc.)An Aobōzu type based on images in Edo-period picture scrolls and regional field collections. Depicted as a monk with a bluish hue or as a one-eyed priest, it may be told as an animal in disguise, a manifestation of a mountain deity, or an uncanny being of uncertain nature. It serves to warn children against wandering, anchors tales of hauntings in fields, mountains, and vacant houses, and conveys oral taboos. No fixed proper name or origin is agreed upon, and its conditions of appearance and behavior vary by region. Because Sekien’s print lacks commentary, notes from other sources list it alongside the “One-Eyed Monk” or as an allegory for an unseasoned priest, but neither view is definitive. In premodern oral accounts, concrete images coexist under multiple labels such as “Blue Priest,” “Great Monk,” and “Little Monk.”

珍しい Sanuki Heike Crab
sah-NOO-kee HAY-keh-gah-nee
Sanuki Heike Crab (Linked to Yashimaura)
Household SpiritsSanuki Province (around Yashimaura near the Awa border)An image based on folk belief that crabs with human-like patterns on their carapaces washed up on Sanuki shores embody the vengeful spirits of the defeated Taira clan. Historical sources tie these crabs to various locales, with Sanuki famed due to memories of the Battle of Yashima. As a yokai, it is said not to harm people directly, but to make onlookers recall the karma of the battle and feel awe. It is distinctly linked with acts of memorial service and consolation for the dead, and differences from other regional names are considered nominal only.

珍しい The Seven Companions
shee-chee-neen DOH-gyoh
Collected Tradition Edition (Shikoku Type)
Ghosts & SpiritsSanuki Province (Kagawa Prefecture)An amalgam of seven-in-a-row ghost tales found across Shikoku. Its core traits are threefold: seven figures advance in single file without a word, they appear at crossroads, on night roads, or at rainy dusk, and an encounter portends misfortune. Names, time of appearance, and garb vary by locale. In Sanuki they look human but are usually invisible, perceptible only through a ritual vantage—peering from beneath a cow’s hindquarters. A subtype limited to crossroads at the dead of night is called Shichi-nin Dōji, and certain once-busy junctions are remembered for their passage. The Shichi-nin Dōshi, who appear in rain wearing straw raincoats and hats, are linked to executed souls; a folk remedy to dispel the gloom after meeting them is to fan oneself with a winnowing basket. In Tokushima, seven child spirits accompanying the Headless Horse are said to have faded after Jizō statues were erected for their repose, reflecting a regional belief that memorial rites quell calamity. Though sometimes conflated with Shichi-nin Misaki, local names and functions differ; Shichi-nin Dōkō are identified by the outward feature of seven spirits marching in a line.

珍しい Aka-ashi (Red Foot)
AH-kah AH-shee
Aka-ashi
General ClassificationsVarious regions of Japan (Shiwaku Islands in Kagawa, Fukuoka Prefecture, Hachinohe in former Mutsu)Based on records from various regions, in places where it shows itself only a pair of red feet jut from the roadside, startling passersby and throwing off their pace. Where it remains unseen, a dry, cottony or cobweb-like touch clings to the shins, shortening strides and increasing fatigue. It is not lethal, yet it is feared for causing falls and leading people off the road. Its relation to the Red-Hand Child is noted in sources but not assumed to be identical. Encounters are told at crossroads, mountain paths, and brush edges in sparsely peopled spots, most often from dusk to midnight. As remedies, some regions pass down practical measures: breathe deeply and steady your steps, sit to retie sandal thongs, brush aside the roadside grass, though details vary locally and remain uncertain.

珍しい Tsurube-bi (Bucket Fire)
TSOO-roo-beh-bee
Traditional Aspect (Kaika Will-o’-Wisp)
Natural Phenomena SpiritsKyoto (Saiin) and mountain woods across Shikoku and KyushuA traditional reading of the Tsurube-bi based on Edo-period ghost tales and Sekien’s imagery. Told across Japan as a tree-born will-o’-wisp, its bluish-white fire-orbs dangle from branch tips and bob up and down like a well bucket’s pulley, misleading travelers. The flame is weaker than it looks and is said not to catch on clothes or vegetation. Early-modern accounts cite fire apparitions around Saiin in Kyoto, and later yokai encyclopedias file it as a will-o’-wisp akin to Tsurube-otoshi or as a separate kind. Sightings are said to peak on moonless or misty nights; when approached it slips away, when left it drifts back. A shadowed face sometimes appears, causing confusion with hitodama, yet it is remembered as a local, earthbound fire spirit.

珍しい Chōchin-bi (Lantern Fire)
CHOH-cheen-bee
Chochin-bi (Lantern-Flame, regional will-o’-the-wisp type)
Natural Phenomena SpiritsAcross Japan (notably Shikoku, Yamato, and Ōmi traditions)A regional catch-all name for ghostly lights about the size of a paper lantern. In some areas it is conflated with kitsune-bi and tanuki-bi, its name stemming from the idea of monsters lighting lanterns. It appears on rainy nights along riverbanks, dikes, and graveyards, drifting at a fixed height. Accounts vary by era and locale: vanishing when approached, splitting when struck, or marching in clusters. In folklore it portends untimely death or a curse and marks taboos along the roadside, anchoring tales that warn against pursuit or striking it. It appears in early modern essays and kaidan, sometimes gaining proper names (such as Koemon-bi) and lodging in local memory. Natural ignition and animal-origin theories coexist, and its true nature remains unsettled.
