Kuzuryū Ōgami of Mount Togakushi is worshipped as a once-violent being transformed through subjugation into a benevolent water deity. The core medieval account tells how the ascetic Gakumon subdued a nine-headed demon and made it a good dragon. Under the name Kuzuryū Gongen, the deity later became a focus of rainmaking rites performed by shrine attendants and Shugendō practitioners. Tradition says that Kuzuryū likes pears. Worshippers offered the fruit when praying for relief from toothache, and from the early modern period the deity also attracted prayers for relationships and marriage. Images vary with time, presenting a divine figure, a serpent, or a dragon, while the sacred geography remains constant: a sealed rock chamber, springs, and mountain ravines. Kuzuryū symbolizes the safety of local water sources and the stability of farming. Its former violence is not imagined to have vanished without trace, but to be quieted through remembrance and continued ritual. The Togakushi deity need not be confused with the Black and White Dragon traditions of Echizen, even though they share the work of a water god: regulating rain and river levels and protecting the lives that depend upon them.

As the water god who stills storms, Ryūjin stands at the meeting of sea and sky and holds the weather in divine power. Fishers, sailors, and rice-growing communities all prayed to this god in moments of need. That power has two edges: timely rain can nourish a field, while great waves and violent wind can break a ship. People therefore developed rites not simply to obtain power from Ryūjin, but to soothe the raging aspect of water and invite its life-giving one. The sea god's greatest treasures are the tide-flowing and tide-ebbing jewels, which command the rise and retreat of the sea. Yamasachi-hiko receives the pair from the sea god, uses one to overwhelm his elder brother with water, and the other to draw it away and save him. Their control of the tide expresses the heart of Ryūjin's authority. Coastal shrines received prayers for calm weather and a rich catch; inland rites sought rain, offered black horses in drought, or lowered offerings into deep pools. Legends from Lake Ashi and other waters in which a monk subdues a dragon and transforms it into a guardian preserve the close bond between fear and reverence. Ryūjin's role as lord of the Dragon Palace grows from the same divinity of water. Beyond the sea or beneath it lies a realm of wealth and a different measure of time. A visitor may return with treasure, or carry away years that cannot be recovered, as Urashima Tarō does when he opens the jeweled box. Ryūjin is therefore not merely a fabulous beast but the deification of water itself, the source on which life and death both depend. To still the storm is also to renew the fragile covenant between human beings and the natural world.

An elderly woman with white hair and a body hardened by life in the mountains, she is famed as the nurturing figure who raised Kintaro. Her deeply lined face reflects priceless life experience, and she offers precise guidance to the lost. Though she may appear strict, a profound love resides beneath the stern exterior.

The core of Ōyama Hōkibō lies in a tale of succession to a seat within the tengu world—the "seat transfer." Yet the Mt. Ōyama on which he sits was a sacred mountain established in antiquity, without need of the transfer legend. The Engishiki Jinmyōchō (927) ranks the Afuri Shrine among the official shrines of Sagami Province, showing that Ōyama's divinity was recognized by the ancient state. On the Buddhist side, the Ōyama-dera engi emaki depicts how Rōben—carried off by an eagle and raised in Nara—opened Ōyama-dera and enshrined Fudō Myōō (the Sagami version; a different work from the engi of Hōki's Daisen-ji). And in early-modern times the official gazetteer the Shinpen Sagami no Kuni Fudoki-kō (1841) conveys the summer ascent season and the bustle of pilgrims from many provinces. The manners of pilgrimage—purifying oneself at the waterfalls under a sendatsu's guidance before climbing—and the Ōyama confraternities everywhere: this density of faith gave Hōkibō, the successor tengu, the character of a guardian watching over the common people. The seat-transfer tradition overlays this sacred-mountain history. According to the arrangement of Chigiri Kōsai of tengu scholarship, Sagami Ōyama originally had a great tengu named Sagamibō. But when the Retired Emperor Sutoku—defeated in the Hōgen Rebellion (1156) and exiled to Sanuki—passed away, Sagamibō removed to Shiramine in Sanuki to console and guard his bitter spirit (= Shiramine Sagamibō). The one who succeeded to the vacant seat of Sagami Ōyama was Hōkibō, come from Mt. Daisen in Hōki. This symmetrical transfer—"Sagamibō to the west, Hōkibō to the east"—is a Chigiri-derived arrangement lacking explicit sources in the classical literature, and should be read not as historical fact but as lore that mirrors the notion that a tengu's seat is succeeded through mountain and bond (en) rather than being a fixed individual. Chanted as "Hōkibō of Ōyama" in the Muromachi Noh play Kurama Tengu, and standing among the forty-eight tengu of the Tengu-kyō, his seat continues to be remembered, together with this distinctive engi, as one of the Eight Great Tengu.

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.

From Sarasvatī to Benzaiten — Two Thousand Years of Cultural Transformation. While the basic description touches on Benzaiten's major sanctuaries and folk beliefs, this in-depth analysis explores her cultural evolution spanning over two millennia from ancient India's Sarasvatī to modern Japan's Benzaiten. Sarasvatī is one of the oldest deities in the Rigveda (c. 1500–1200 BCE), governing river flows, music, arts, language, and poetry. After being adopted into Buddhism, she was transformed into a tutelary deity in the Golden Light Sutra and Lotus Sutra, spreading to China, Korea, and Japan. In Japan, she evolved through several stages: (1) as a scriptural protector during the ancient Ritsuryo Buddhist period (7th–9th centuries); (2) merging with Ugajin to form Uga-Benzaiten in the medieval Kamakura period; (3) becoming a deity of wealth and a member of the Seven Lucky Gods in the early modern Edo period; (4) having her enshrined identity frequently altered to Ichikishimahime during the Meiji era's separation of Shinto and Buddhism; and (5) transitioning into a subject of modern superstitions, tourism, and subculture. She stands as a prime example of an ancient deity's cultural evolution, continuously transmitting her legacy while altering her appearance, attributes, and name over two millennia. Ugajin — The Mysterious Human-Headed Snake Deity. Ugajin, who merged with Benzaiten from the Kamakura period onward, is a bizarre figure depicted with a human head and a coiled snake body, and remains a mystery in academic studies. While the etymology of "Uga" points to the grain deity Ukanomitama from the Kojiki and Nihon Shoki, the origins of the serpent imagery are debated, with theories citing influences from the Chinese creator deities Fuxi and Nuwa, the Indian Naga (serpent gods), and indigenous Japanese snake worship from sites like Mount Miwa and Suwa. The amalgamation of a "uniquely Japanese snake deity of unknown origin" with a "Buddhist goddess of Indian origin" to form Uga-Benzaiten is a symbolic testament to the syncretism, creativity, and mysticism of medieval Japanese religious culture. Two-Armed vs. Eight-Armed Statues — Dual Iconographic Lineages. There are two main lineages of Benzaiten statues. (1) Two-Armed Statues: Depicting an elegant heavenly maiden playing a biwa (lute). This lineage inherits the original musical goddess nature of Sarasvatī and has been the traditional form in Japan since the Heian period. (2) Eight-Armed Statues: Depicting a heavily armed warrior goddess holding eight weapons and ritual implements such as a sword, jewel, bow, arrow, axe, halberd, dharma wheel, and vajra. This form, described in the 5th–6th century Chinese translation of the Golden Light Sutra, emphasizes her role as a protector of the state. The eight-armed figure embodies a fierce martial nature quite distinct from the "elegant goddess of arts" image. Combined with the medieval serpentine form of Ugajin, Benzaiten evolved into an immensely complex deity integrating "elegance, martial prowess, magic, and wealth." The Folklore of Serpentine Transformation — A Layering of Water, Wealth, and Fertility Gods. The transformation of Benzaiten (Uga-Benzaiten) into a snake deity is a folkloric phenomenon deeply intertwined with ancient Japanese snake worship (Mount Miwa, Suwa, Usa, Kumano, etc.). In ancient Japan, the snake was revered as a deity uniting four attributes: water (shrines by rivers, ponds, and the sea), wealth (shedding skin, infinite multiplication), fertility (grain and land), and healing (medicine and taboos). As a result of Benzaiten's fusion with Ugajin and acquisition of snake deity traits, all layers of ancient snake worship—waterside shrines, snakes in wallets, shed skin amulets, and prayers for healing—have been inherited as part of "Benzaiten faith." Even today, modern superstitions like "money-washing water, wallet snakes, and relationship-severing" vividly demonstrate the living heritage of a folk culture where ancient snake gods, medieval Benzaiten, early modern wealth deities, and modern tourism intersect. The Couples' Taboo — Modern Superstition of a Jealous Goddess. At major Benzaiten sanctuaries (especially Enoshima and Itsukushima), a modern superstition prevails that "couples who visit together will incur the beautiful goddess's jealousy and break up." This is a modern variation of an ancient Indian fierce goddess nature (Sarasvatī is sometimes depicted as the wife of Brahma, possessing jealousy and passion), medieval Japanese snake attributes (snakes were symbols of jealousy and attachment), and ascetic taboos such as the historic ban on women on sacred mountains. Going beyond mere superstition, it stands as a fascinating phenomenon condensing the complex religious, folkloric, and psychological history from antiquity to the present, making it a subject of study in 21st-century folklore, psychology, and tourism studies. At the same time, connections with "relationship-severing shrines" (like Yasui Konpiragu in Kyoto) have been noted, showing how Benzaiten's taboo nature integrates with modern cultural practices of seeking separation. The Seven Lucky Gods Faith and Edo Commoner Culture. As the only female member of the Seven Lucky Gods (Ebisu, Daikoku, Bishamonten, Benzaiten, Fukurokuju, Jurojin, and Hotei) established in the Edo period, Benzaiten became a central figure in commoner culture. Practices such as the New Year's Seven Lucky Gods pilgrimage, placing a treasure ship picture under one's pillow, hatsumode (first shrine visit of the year), and praying for business prosperity deeply permeated Edo daily life. This represents a significant cultural shift from the medieval Uga-Benzaiten faith (esoteric Buddhism, mysticism, aristocratic culture) to the early modern Seven Lucky Gods faith (commoners, commerce, urban culture). Benzaiten's early modern worship marks a crucial milestone in an epic cultural transformation spanning over two millennia: from an ancient Indian goddess of arts, to a medieval Japanese esoteric deity, to an early modern Japanese deity of wealth, and finally into a subject of modern tourism and subculture. Benzaiten in the 21st Century — Tourism, Subculture, and Severing Ties. In the 21st century, Benzaiten's legacy continues as a tourism resource through the Three Great Benten Shrines, nationwide Benten shrines, and Seven Lucky Gods pilgrimages. Simultaneously, she is repeatedly reimagined in subculture works, such as the video games *Okami* and *Megami Tensei*, and the manga *Nura: Rise of the Yokai Clan*. She has become a multifaceted icon where ancient Indian goddess traits, medieval Japanese snake attributes, early modern wealth associations, and modern relationship-severing taboos intersect. As a rare example of a single deity embodying over two thousand years of cultural evolution—from Sarasvatī in ancient India to Benzaiten in modern Japan—she remains a vital subject of study in yokai studies, folklore, religious history, and comparative mythology.

In this version, we read Sakata no Kintoki as "the warrior who brings the power of Mt. Ashigara back to the capital." Kintoki does not appear as a polished samurai from the start. As Kintaro, he is a boy of superhuman strength raised by a yamanba, intimate with bears and beasts, carrying a broadaxe. This childhood image retains the strangeness of a child raised outside human society. The scene where he is discovered by Yorimitsu is the moment the direction of Kintoki's power changes. The superhuman strength naturally exerted in the mountains is converted into the abilities of a warrior serving a lord. This is also a story of civilizing wild power. Kintoki does not discard the otherworldly realm of the mountains, but enters the Four Heavenly Kings carrying that power. Because of this, he possesses an exceptional body within the samurai band of the capital. In the subjugation of Shuten-doji, Kintoki is a figure who confronts the demons of the mountains using the power of the mountains. The demons of Mt. Oe are anomalies secluded outside the capital, and Kintoki likewise possesses power from the otherworldly realm of Mt. Ashigara. The two can be seen as entities that have distributed the same mountain power to different sides. If the demon is the otherworldly power threatening human society, Kintoki is the warrior who has reclaimed that power for the human side. The brightness of Kintaro's image was greatly emphasized in its reception in later eras. In May dolls and children's songs, Kintaro becomes a symbol of health, robustness, and growth. However, if we only look at that healthy boyish image, yokai-like elements such as the yamanba, beasts, and superhuman strength fade away. In this version, we read him while retaining the outline of the prodigy raised in the mountains behind the cheerful folk character. Sakata no Kintoki is not a yokai, but he represents "supernatural ability on the human side" in yokai tales. He does not confront the demons from completely within human society; he confronts them with a power nurtured in a place close to mountain anomalies. Therefore, even among Yorimitsu's Four Heavenly Kings, he is a presence standing on the boundary between the capital and the mountains, child and warrior, hero and abnormality. Kintoki's superhuman strength is not just about being strong; it raises the question of where that power came from. Is he strong because he was raised with beasts on Mt. Ashigara, or did he gain otherworldly power through the yamanba's blood or upbringing? The legends do not answer clearly. That ambiguity places Kintoki on the border between humans and yokai. Being summoned by Yorimitsu is a socialization for Kintoki. He, who was a free boy of superhuman strength in the mountains, gains a lord, a name, and becomes a member of the Four Heavenly Kings. The power of the otherworldly realm changes into the power of a samurai family by being given a name and a role. Herein lies the great transformation from Kintaro to Sakata no Kintoki. In this version, we also do not take the brightness of the Boys' Festival lightly. When households wishing for their children's growth display Kintaro dolls, the superhuman strength of the mountains turns into a blessing. Yokai-like power, rather than being feared, becomes a symbol of protecting and raising children. Kintoki is also a rare example where otherworldly power was gently converted into domestic wishes. The story of Kintoki is not one of eliminating otherworldly power, but of re-nurturing it. The power nurtured under the yamanba does not disappear even when he comes to the capital. Rather, by gaining a role under Yorimitsu, it turns into the power necessary for demon subjugation. This is where the fascination of bringing yokai-like elements to one's own side lies. This gentle transformation is what makes Kintoki an intimately familiar hero even today.

Ehon Hyaku Monogatari presents Maikubi as the vengeful heads haunting the sea off Manazuru. Although the warriors have been beheaded, their hatred survives: the three heads keep biting one another and breathe fire from their mouths. The book preserves two explanations for their deaths. One begins with a quarrel and sword fight during a festival; the other says that several men were executed for gambling. In either account, the heads move by themselves, dance over the water, and create whirlpools and ghost lights. Their circling is also tied to the place-name Tomoe-ga-fuchi. Later kibyōshi picture books and yomihon novels reused similar images of three linked heads in flight. As a coastal ghost story, Maikubi preserves fear of the severed head and of the grudge left by private violence, while also warning of the real danger around deep water and rocky shores.

A version organized from folklore materials of a child-shaped mountain spirit seen in the eastern Tanzawa mountains. Generally harmless, it simply follows quietly behind travelers, yet at times steps ahead at forks to guide them onto the right path. It wears rough straw matting or homespun, sometimes pelts, blending into the forest’s shadow and vanishing when one turns back. It is said to appear most often in the afternoon, and at night to carry a small light like a lantern. Those who meet it repeatedly often think of lost children and leave rice balls, yams, sweets, or dried persimmons on rocks or stumps as offerings. Some accounts say it fades away as one nears the villages, others that it withdraws when called to at night, and none describe it as vengeful. Rooted in overlapping ideas of mountains and the dead, it stands as a symbol of the boundary nature of the mountain realm.

Based on the depiction of Mizude in Takehara Shunsen’s Ehon Hyaku Monogatari. As censure for the abandonment of a corpse, bare bones rise of their own accord to sing and dance, symbolizing that mistreating the dead invites the uncanny. Closer to a tale of vengeful spirits than to a mere monstrosity, it manifests signs from the unoffered dead. Though the dancing and singing appear comical, the didactic thrust is strong, urging proper funerary rites. Specific places and names—Yuigahama, Hachirō of Tone, Hōjō Tokiyuki—anchor the story in the memory of war chronicles. The plot in which temple monks bury the bones to quell the anomaly exemplifies the temple’s social role of pacifying spirits through memorial rites.

A整理 of the Mikari-bā (Mikakari-bā) yokai as preserved in folklore. She appears on Koto-yōka (the eighth days of the month) as a one-eyed crone, enforcing restraint on housework and outings. Her act of “borrowing” winnowing baskets and human eyes links to avoidance of mesh-patterned tools and symbols with many eyes, giving rise to countermeasures like placing baskets or sieves at the gate, or fixing a mesh basket to a pole on the roof ridge. In the Kōhoku, Yokohama accounts, her greed extends to gleaning even fallen ears of grain, and depictions of her carrying fire in her mouth serve as a caution against conflagration. In southern Chiba, customs of taboo and house-seclusion called “Mikari” (body-substitution) recast pre-festival liminality as a yokai rule. Despite regional variation, these tales share a framework that transmits norms of household safety, fire prevention, and labor abstinence at seasonal thresholds from winter to spring. Creative embellishments are set aside in favor of points attested in Kanto eyewitness reports and folklore records.

A compiled standard telling of Akashi-sama from Hodogaya Ward. Its core traces to the late Edo period: a deranged lord craved bloodshed, cut down a hunter’s daughter, and was slain by the hunter. Thereafter the name was feared and spread as an oral warning against going out at night. Details like appearance, clothing, and the hour of manifestation are inconsistent; storytellers stress effects such as “it appears” or “it takes you away.” This is a scare-tale type of uncanny being tied to local norms, functioning practically in household discipline and communal safety. Identifying real persons or places requires caution; it is sometimes paired with the proper name “Akashi Gozen,” but lineage remains unclear.
