神格 Kuzuryū (Nine-Headed Dragon)
koo-zoo-RYOO
Togakushi Kuzuryu Ōgami (Great Nine-Headed Dragon of Togakushi)
Deities & Divine SpiritsTogakushi in Shinano Province; Kuzuryū River basin in Echizen ProvinceThe Kuzuryu Ōgami of Mount Togakushi is venerated as a water deity pacified through subjugation and transformed into a benevolent god. Medieval accounts center on a tale of pacification and sanctification by a figure known as Gakumon, after which the deity became revered as Kuzuryu Gongen, a principal icon for rainmaking, integrated into the rites of shrine attendants and Shugendō practitioners. It is said to favor pears as offerings, and from the early modern period was believed to cure toothache and bless marriages. Its representations vary by era—divine statue, serpent form, or dragon form—and it is linked to rock grottoes, springs, and ravines. As a guardian of local water sources and a symbol of agricultural stability, its tempestuous aspects are understood to be soothed through requiem rites and festivals. Even without mixing with Echizen traditions of the Black and White Dragons, it shares the essential functions of a water god, governing rain, river levels, and community livelihood.

神格 Takeminakata
takeminakata
Suwa Myojin: The Independent King of Water and War
神霊・神格諏訪大社·上社本宮 (現·長野県諏訪市中洲、 信濃国一宮) / 諏訪大社·上社前宮 (現·長野県茅野市宮川) / 諏訪大社·下社秋宮 (現·長野県諏訪郡下諏訪町) / 諏訪大社·下社春宮 (現·長野県諏訪郡下諏訪町) / 全国諏訪神社 (約 1 万 1 千社·信濃·関東·東北中心)Identity as the Resisting God. Takeminakata is the only rebellious deity who attempted physical resistance against the order of the heavenly realm (Takamagahara). The essence of "resistance against centralization" and "regional independence (indigeneity)" is deeply etched into his nature. His defeat and confinement in Suwa serve as a metaphor for the Yamato Kingship's pacification of the Japanese archipelago; yet, within the enclosed basin of Suwa, he never withered away. Instead, he cultivated a fierce, indigenous energy (epitomized by the frenzied Onbashira festival) powerful enough to surpass external authority. He possesses a dark hero-like charm—"defeated, yet unyielding"—which is exceptionally rare in Japanese mythology. Manifestation as a Dragon God (Water God). Takeminakata is also frequently spoken of in the form of a massive dragon or snake god dwelling in Lake Suwa. The natural phenomenon known as "Omiwatari," where the lake freezes completely in winter and the ice violently cracks and buckles upward with a roaring sound, is believed to be the trail left by Takeminakata (Kamisha) visiting his consort, Yasakatome-no-kami (Shimosha). For ages, this has been an important ritual for predicting the year's fortunes and agricultural yields. His power as a dragon god who controls wind and rain to bring water was an object of absolute awe and gratitude in agrarian societies. The Onbashira Festival and the Regeneration of Energy. Essential to the discussion of Takeminakata's worship is the "Onbashira Festival," an extraordinary nationwide festival held every seven years. Massive logs are cut from the mountains, ridden down steep slopes at the risk of people's lives (Ki-otoshi), and erected at the four corners of the shrines. This savage festival is the crystallization of indigenous tree worship—such as that of Mishaguji—and the ferocious martial spirit of Takeminakata. By periodically replacing the massive trees that house the divine spirit, the god's energy is regenerated and amplified, imparting vitality to the earth. It powerfully conveys the zenith of animism continuing from ancient times into the present day.

伝説 Kama-itachi
kah-mah-ee-TAH-chee
Kama-itachi
Animal ShapeshiftersCentral Japan, Kinki, and Shin’etsu regions (various locales)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.

伝説 Yuki-onna
Yuki-onna (the Snow Woman)
The White Apparition of the Snow-Country Night
Natural Phenomena & Nature SpiritsThe heavy-snow country of the Sea-of-Japan coast and northern Tōhoku, on HonshūAs a "white apparition," the Yuki-onna is told of as a white figure that suddenly stands in one's path on a blizzard night, leaving no footprints. Before she draws near, the air first turns cold and one's breath freezes white; then, in the glow of the snow, a woman with a long trailing hem floats dimly into view. This sense that "the cold announces her before she comes" is the shared core of encounter-tales across the regions. Her face alone is translucently pale, her eyes glint from within, and she either gives no answer when addressed or asks one's name in a low voice. In many versions the taboo runs thus: answer her question and your life-force is drained; stay silent and you are spared. The tale of Minokichi and O-Yuki that Lafcadio Hearn set down in Kwaidan conveys this white-apparition image most vividly. Having frozen the old woodcutter Mosaku to death in a storm-bound hut, the snow woman leaves the young Minokichi with a single command: tell no one what you have seen tonight. Later Minokichi weds a traveling woman named O-Yuki, fathers children, and lives happily — until one snowy night, watching his wife's pale profile as she sews by lamplight, he sees in her the face of the snow woman of long ago and lets the words slip. O-Yuki reveals herself, declares that she spares him only for the love of their children, and vanishes through the smoke-hole as a white mist. A bond sealed by a single forbidden word comes undone: the sorrow of parting, and the otherworldly woman who longs for a human, crystallize here. In pictorial tradition she is usually painted as a tall woman in white in pale washes, her outline never drawn too firmly, dissolved into a white scarcely distinguishable from the snow. Her feet are blurred into haze and she casts no shadow, lending the air of something not of this world. Less a spirit who sings and dances than a still apparition who stands without sound and vanishes without sound — that is the true nature of the Yuki-onna as a "white apparition."

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 Iizuna Saburō
Iizuna Saburō
The War-God Who Rides a White Fox — Iizuna Saburō
Mountain & Wilderness SpiritsMt. Iizuna, Shinano Province (Nagano City, Nagano)To read Iizuna Saburō, one must overlay three strata: the syncretic honzon-image of "Izuna Gongen," the heterodox art of the "Izuna method," and the devotion of the Warring-States commanders. The antiquity of this faith is backed by the texts. The Asabashō of the first year of Kenji (1275) carries the name of Mt. Iizuna and its founding ascetic; the Togakushi-san Kenkō-ji Ruki (1458) records "Izuna Saburō" and "the third tengu of Japan"; the Iizuna-san Meguri Saimon (1546) gives the origin as the Chira Tengu come from Tenjiku; and the Iizuna-san Ryaku Engi transmits the honji-butsu and the lineage of the Sennichi-dayū. From Kamakura to Edo, it is a faith handed down in layers. The iconography of the honzon is profoundly distinctive. A crow-tengu holding a sword and a rope rides upon a white fox, with a snake often coiling about the fox. Its honji-butsu is expounded now as Fudō Myōō, now as Dakini-ten, varying by source. It is precisely this composite character—"tengu, fox, Fudō and Dakini" joined in a single body—that is the reason Izuna Gongen, surpassing a mere mountain tengu, became a point of concentration of esoteric ritual power. At Takaosan Yakuō-in, the Iizuna Shrine of Shinshū, Jinya-ji on Mt. Kano in Chiba and elsewhere, the faith is especially deep in Kantō and to the north. The "Izuna method" is the practical face of this ritual power. This sorcery, which employs tengu and kuda-gitsune to heal illness and, by possession, to deliver oracles, was counted a heterodox art alongside the Atago Shōgun-hō and the Dakini-ten-hō, and those who wielded it were called Izuna-tsukai. The folk belief that one kept and employed kuda-gitsune within a bamboo tube made the very name "Izuna" a byword for witchcraft. And it was the devotion of the warrior houses that raised Iizuna Saburō to a war-god. It is famous that the crest of Uesugi Kenshin's helmet was an image of Izuna Gongen; there is also the case of Takeda Katsuyori granting the name Nishina to the adopted son of the Sennichi-dayū, and commanders such as Hosokawa Masamoto who practiced the Izuna method itself. As a god who governs victory in war, Iizuna Saburō is, even among the forty-eight tengu of the Tengu-kyō, the seat most bound to this-worldly benefit. Chigiri Kōsai of tengu scholarship placed this many-sided Iizuna Saburō within the system of the great tengu of the many mountains.

伝説 Jorōgumo (Enchanting Spider)
jo-ROH-goo-moh
Tradition-Faithful Jorōgumo Archetype
Animal ShapeshiftersVarious regions across Japan (notably Izu and Sendai)A Jorōgumo based on the canonical image found in Edo-period sources. A great spider, having aged into a yokai, assumes the form of a young woman or a mother and child to exploit lapses in human judgment. She appears at liminal places such as waterfalls, deep pools, verandas at the edges of mountain villages, and abandoned houses, casting many layers of silk to bind victims and dull their judgment through sleep or enchantment. Toriyama Sekien depicted her commanding fire-breathing spiderlings, helping fix motifs of acting in groups and fleeing into the upper parts of houses such as the attic. In some regions she is deified as a protector against drowning, with stones or small shrines raised in her honor. Many tales end with her being thwarted by human wit—cutting her threads and tying them to a stump, or seeing through her disguise—while others warn of taboos where breaking a vow of secrecy brings death, or of fatal infatuations that drain one’s life. This profile avoids modern embellishment and stays within the breadth of existing tradition.

名妖 Rain Woman
AH-meh-ON-nah
Rain-Summoning Female Spirit
Weather & Calamity SpiritsVarious regions of Japan (notably Shinshū/Nagano and the Kantō area)In historical sources, Ame-onna first appears in Toriyama Sekien’s illustrations, though his entry leans on an allegory from Chu, leaving the standalone monster image faint. In oral traditions nationwide two types stand out. One is a female apparition on rainy nights that targets children (such as Shinshu’s “Ame-onba”), with motifs like approaching crying children on night roads and carrying a sack. The other is a numinous being that summons rain in drought, tied to rain-invoking rites and shrine prayers, venerated as a symbol of blessed showers. Rather than contradicting each other, these reflect a folk reading of rain’s dual gifts and perils. From early modern times, a nickname meaning “one who brings rain” also stuck to individuals, but that is a social label, not a yokai image. Sources vary widely by region, and many tales leave names and citations unspecified.

名妖 Amazake Hag
ah-mah-ZAH-keh BAH-bah
Traditional Folklore Aligned
Half-Human BeingsTohoku and Kanto regionsAmazake-babaa was told as a visitor who heralds the arrival of epidemics. She knocks at midnight and asks whether there is sweet sake; the very act is a test of taboo, and answering is understood as a conduit for misfortune. People hung apotropaic symbols—cedar sprigs, nandina, and chili peppers—at their gates and avoided replying. Across Edo, people visited images of an old woman said to calm coughs, linking petitions to folk belief. The tradition overlaps memories of smallpox outbreaks; some view her as a guise of the smallpox deity, while others absorbed the image of a peddler woman on cold nights, creating regional variation. The yokai is transmitted with the taboo structure of “answer and you fall ill,” accompanied by threshold-warding rites, and is positioned as a portent tale that signals the presence of disease.

名妖 Azuki-arai (Bean Washer)
ah-ZOO-kee ah-RAH-ee
Azukiarai of the Mountain Stream
Ghosts & SpiritsVarious regions—especially mountain valleys in Kanto, Chubu, and KinkiRooted in the classic image of the Azukiarai, it blends with the sounds of ravines and flumes, washing red beans through the midnight hours. It lures with sound and tests the curious who peer in. Drawing on early modern notes that it excels at counting and judges vessel measure and bean quantity at a glance, it is not wantonly harmful, but serves as a keeper of taboos along the water’s edge.

名妖 Hihi (Demon Baboon)
HEE-hee
Hihi (Traditional Accounts)
Animal ShapeshiftersVarious regions (mountain areas)A depiction of the hihi based on Edo-period images and folklore. Said to dwell in mountains, it is an aged monkey transformed into a giant, powerfully built being. Many regions tell that it bursts into loud laughter, and when its long upturned lips roll back to cover its eyes, it leaves an opening to strike. Tales include the abduction of women, bouts with woodcutters, and raising wind and storm to hurl people. Natural history compendia such as Wakan Sansai Zue report black hair, large size, and hearsay of human speech, though exact locales and physical evidence remain uncertain. Its name is commonly linked to its laugh. It is sometimes conflated with yama-warawa or monkey deities, but is often distinguished as an ape-shaped mountain monster.

稀少 Hidden Hamlet
kah-koo-reh-ZAH-toh
Sekien Zue Version: Hidden Village
山野の怪Japanese folkloreAn interpretation based on Toriyama Sekien’s Konjaku Hyakki Shūi entry “Kakurezato” (Hidden Village). The mouse and koban coins at the lower right recall tales in which subterranean mice carry wealth (the so‑called Nezumi Jōdo legend), hinting at ties between the village and chthonic or underworld realms. The shop curtain reads “Kakurezato,” expressing a boundary that opens suddenly as an extension of the everyday. The Hidden Village is not a single yokai but a boundary acting as if it has will, repeating wayfinding confusion, temporal slippage, the granting of fortune, and cycles of manifestation and disappearance. Outcomes swing with a visitor’s conduct and greed, from generous hospitality to wealth turning into leaf-litter, resonating with mountain otherworld tales and views of the beyond.

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.”

稀少 Banana-Plant Spirit
bah-SHOW-noh-SAY
Tradition-Faithful, Sekien Illustrated Edition
Natural Phenomena SpiritsAcross Japan (notably Ryukyu and Shinshu traditions)A整理 based on the plant-spirit of banana (bashō) as pictured in Toriyama Sekien’s Konjaku Hyakki Shūi. The broad leaves rustle and cast uncanny shadows in wind and rain, thought to summon the strange, with the belief that an aged clump comes to harbor a spirit. It takes the form of a beautiful woman to unsettle both clergy and laity, posing the riddle of whether grasses and trees can attain Buddhahood, and vanishes depending on one’s response. Tales include encounters in Ryukyuan banana groves, an apotropaic rule that those who carry blades are spared, and Shinano stories where striking it leaves the bashō stalk wounded by morning. It is not consistently harmful, more often serving as a warning through shock and confusion. Typical settings are temple gardens, banana plots, and manor yards.

珍しい Iwanabōzu (Monk Trout)
ee-wah-nah-BOH-zoo
Iwaname Monk (Tradition-Faithful)
Animal ShapeshiftersMino Province (Ena District) and various regions of JapanBased on Edo-period records and regional folktales. An aged char trout appears in the guise of a Buddhist monk and speaks to anglers. It often urges moderation, citing the temple’s domain or the pool’s lord, and departs quietly if given alms. Later it may be caught as a great char, where rice or rice cakes given as alms are found in its belly, revealing its identity. The motif reflects reverence for river and pool guardians and ideas akin to eel and other water deities. Depending on region, it appears as a harmless, didactic type, a warning type bearing deadly poison, or a salvific type that sacrifices itself to stop a levee breach, yet all embody folk norms that safeguard the boundary between waters and livelihoods.

珍しい Oni Bear
OH-nee KOO-mah
Tradition-faithful Oni-Bear
Animal ShapeshiftersKiso Valley, Shinano Province (Nagano Prefecture)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.

珍しい Momijigari (The Demon of the Maple Viewing)
moh-MEE-jee-GAH-ree
Demoness Momiji (Performing Arts Tradition)
鬼・巨怪Togakushi Mountain, Shinano Province (Nagano), JapanA demoness archetype fixed in Noh, joruri, and kabuki from the Muromachi to Edo periods. She appears under the pretext of autumn leaf viewing as a courtly lady-in-waiting or princess’s attendant, lulling suspicion with music and dance. At the feast she inebriates warriors, but near midnight her nature is exposed by divine protection or a sacred blade, and she reveals her true form in the wilds of Mount Togakushi. Commonly called Momiji, she bears aliases such as Princess Sarashina depending on the work. Her slaying tales extol martial virtue and reflect awe of the mountains, inheriting Togakushi worship and the rhetoric of oni-hunting lore. On stage, the contrast between the elegant disguise of the first act and the ferocious demon visage of the second is emblematic.

珍しい Smiling Hannya
wah-RAH-ee HAHN-nyah
Edo Painting Traditions Edition
Demons & GiantsShinano Province (Higashichikuma District, Nagano Prefecture), and elsewhereAn edition distilled from late Edo-period ukiyo-e and comic prints depicting the smiling Hannya. Horns, fangs, bristling hair, wide staring eyes, and a strained grin form its core. Objects in its hands often allude to life and death, unsettling viewers with deliberate motifs. The demon-woman is understood to have once been human, transformed by accumulated jealousy, resentment, and attachment, aligning with the concept behind the Hannya mask. Specific local legends are sparse, yet it was treated in night-time tales and picture books as a symbol of fear and admonition, preserved as an image of the extreme of a woman’s grudge. In local oral tradition sometimes only the name remains, with the transmission of its form relying mainly on pictorial sources.

珍しい Snow Elder
YOO-kee-jee-jee
Elder of Snow Standing in the Mountains
Natural Phenomena SpiritsMountain regions of Tohoku, Hokuriku, and Koshin (uncertain)When the curtain of a blizzard falls, the Snow Elder appears as an old man in white robes, calling from afar to strip travelers of their sense of direction. He belongs to the lineage of snow-related apparitions, overlapping in role with Yuki-onna and Yuki-nyūdō, yet marked by his elder form. His figure is indistinct, fading the closer one approaches, while only his voice is said to echo from behind. In folklore he is understood as a symbolic warning against the perils of winter weather.
