Yokai Encyclopedia

If one were to treat Mishaguji as a "yokai," it should be viewed not as a terrifying monster, but as a being existing on the border between kami and yokai. Its essence does not lie in folktale tropes like attacking people, shape-shifting, or appearing on dark roads at night, but rather in the spiritual power of stones, trees, pillars, and land invoked through rituals. In Suwa, Takeminakata, Moriya, the Moriya clan, and the Onbashira Festival overlap in complex ways, leaving behind a thick layer of faith that cannot be fully explained by the deities of central mythology alone. Mishaguji is the key to reading this underlying stratum, a presence that transforms Suwa from a mere "stage of myths" into a "place where the land itself harbors the divine."

The charm of Moriya-no-kami lies in the fact that he is spoken of not as the victor of the central mythology, but as the deity who was there first. Takeminakata-no-kami is the Great God of Suwa standing at the center of the official historical view of Suwa Grand Shrine, but the story of that god entering Suwa requires a god on the receiving end. Moriya-no-kami fulfills that role. He is not a god who fights, loses, and vanishes, but one who, after reconciling, enters into the ritual order as the High Priest. Therein lies a uniquely Suwa-like layering of faith, not merely conquest and replacement. When reading Onbashira, Mishaguji, the Moriya clan, and Suwa Myojin as a single geological stratum, Moriya-no-kami stands precisely at the boundary of those layers.

A canonical image of Muginodo Daimyojin found in measles prints. A formidable deity subdues a red-black oni under both feet while onlookers press their hands in prayer. Though the god’s origins are unclear, the image renders the disease visible and calms anxiety through the act of trampling. The accompanying text lists convalescent care, dietary restrictions, and prayers for recovery, blending devotion with practical guidance. The design reflects the plain sincerity of folk belief.

A compiled version of the Myōtaraten images rooted in local faiths of Echigo Yahiko and Okitama in Dewa. Their origin tales involve transformations of an old woman, an ogre, or a shapeshifting cat, whose ferocity is quelled when enshrined, after which they call rain and protect children and the virtuous as village guardian deities. Though bearing a Buddhist-style celestial name, the being is essentially a deified female presence embodying the numinous power of mountains and borders, centered on faith around Mount Yahiko and the Ichihon-yanagi wayside shrine. One tradition says thunder roars once a year when she returns to Sado, aligning agrarian views that link thunderstorms with harvests. Names and forms vary—old crone, celestial maiden, demoness—but the core is a turn toward benevolent protection.

The true essence of the Namahage lies in "blessings through awe." The act of clashing knives and storming into a house with loud voices is meant to engrave a powerful admonition upon children and the lazy; the violence itself is not the goal. Through a dialogue with the head of the household, the Namahage extracts a promise of diligence for the coming year, exorcises misfortune, and departs. This series of rituals has functioned as a mechanism to spiritually brace the entire village at the turning of the year. The design and color of the masks, the movements, and the spoken lines differ from village to village. Some areas receive visits in pairs, while others have strict rules for the visiting order and the etiquette of the dialogue. The straw that falls from their kede garments is picked up as a lucky charm for good health, demonstrating how the folk tradition links the deity's visit to practical, worldly benefits in various locales. The core of the Namahage event is not merely fearing them as demons, but treating them as "guest deities" (marōdogami) complete with rituals of welcome and farewell.

The Structure of the Ancient State Myth: "Tenson Korin". While the basic description touches upon the outline of the Heavenly Descent, this deep dive explores the structure of the "Tenson Korin" as the foundational myth of the ancient Japanese state. The Tenson Korin depicts the divine descent from Takamagahara (the celestial world of purity and order) to Ashihara no Nakatsukuni (the earthly world of chaos and conquest) as the core myth establishing ancient Japan's foundation, ruling authority, and the origins of agricultural civilization. Its intricate structure—involving specific artifacts (the Three Sacred Treasures), attendants (the five pillar gods), commands (the divine decree), and bedding (the Madoko-ofusuma)—forms the fundamental basis for religious ceremonies like the ancient enthronement rituals, the Niiname-no-Matsuri, and the Daijosai. Transcending a simple mythological tale, it is a foundational narrative device that has threaded through Japanese state, religion, politics, and culture from antiquity to the modern era. Comparative Mythology of Descent Myths in World History. In global mythology, the Tenson Korin myth is positioned as a quintessential example of "heavenly descent/divine incarnation" myths. From the Dangun myth of the Korean Peninsula (Hwanung, son of the Lord of Heaven, descending to Mount Taebaek), to the legends of Genghis Khan in Mongolia, the shaman descent tales of northern Tungusic peoples, the descent of Krishna in India, and the Incarnation in Christianity, "divine descent from heaven to earth" myths are widely distributed across the ancient world. The similarities with descent myths in Northeast Asia (like Korea and Mongolia) present a crucial comparative religious question, suggesting that ancient Japanese mythology may have formed within a broader Northeast Asian cultural sphere. Understanding the Tenson Korin not as an isolated Japanese phenomenon but as a Japanese variation of a shared ancient Northeast Asian mythological imagination is a significant achievement of post-war Japanese mythological studies. The Historicity of the Descent Site Controversy. The fact that the alleged location of Ninigi's descent site, "Takachiho Peak in Tsukushi Hyuga," is split between two major traditions—Takachiho Town in Miyazaki Prefecture and the Kirishima mountain range in Kagoshima Prefecture—is the result of the ancient state myth evolving through multiple layers of regional folklore, geographic manifestation, and political competition. The ancient central government (the Yamato Court) did not pinpoint a specific location, adopting the abstract name "Takachiho in Hyuga," allowing independent "our land is the descent site" traditions to develop throughout southern Kyushu across the medieval, early modern, and modern periods. Amid modern tourism branding rivalries, local historical research, and shrine heritage systems, the two major traditions coexist, functioning as unique cultural resources. This is a classic example of how ancient mythology is multi-layeredly integrated into regional culture. Konohanasakuya-hime and the Origin of Lifespan ── The Choice Between Beauty and Eternity. The fact that Ninigi-no-Mikoto's choice of Konohanasakuya-hime (the cherry blossom goddess) and rejection of Iwanaga-hime (the rock-eternal goddess) became the origin myth explaining why his descendants—the Imperial lineage and humanity—lack eternal life illustrates the "fundamental tension between beauty and eternity" in ancient Japan. The contrast between the beautiful but fleeting cherry blossom and the ugly but eternal rock demonstrates the root structure of the ancient Japanese view of life, aesthetics, and impermanence. As a uniquely Japanese concept of impermanence predating the introduction of Buddhism, this idea has been passed down as a foundational philosophy threading through later Japanese culture, including Ukiyo (the floating world), cherry blossom appreciation, Bushido, and the tea ceremony. It serves as crucial material providing the mythological basis for the Japanese aesthetic of "it is beautiful precisely because it fades." From Umisachi-hiko and Yamasachi-hiko to Jimmu's Eastern Expedition. Among the three children of Ninigi-no-Mikoto and Konohanasakuya-hime, Yamasachi-hiko (Hoori-no-Mikoto) visited the Sea God's palace, married Toyotama-hime, and fathered Ugayafukiaezu-no-Mikoto, who in turn had Emperor Jimmu with Tamayori-hime. This four-generation lineage forms the core of ancient Japanese state legitimacy. Jimmu's Eastern Expedition (the myth of Emperor Jimmu migrating east from Hyuga to Yamato to ascend the throne) is the logical conclusion of the Heavenly Descent, mapping the establishment of the ancient Japanese state as a three-stage geographic migration: "Takamagahara → Hyuga → Yamato." As the starting point of ancient state mythology, Ninigi-no-Mikoto is the foundational deity spanning over two millennia of political history, from Jimmu's expedition and successive enthronements to the ancient Ritsuryo system, pre-war State Shinto, the post-war Imperial family, and the modern Emperor system. The Tenson Korin Cultural Sphere of Southern Kyushu. Southern Kyushu (Miyazaki, Kagoshima, and southern Kumamoto Prefectures)—the primary area enshrining Ninigi-no-Mikoto—has developed unique religions, cultures, and folklore as the "Land of the Heavenly Descent" since ancient times. With the Yokagura of Takachiho Town (a Nationally Designated Important Intangible Folk Cultural Property reenacting the opening of the heavenly rock cave), the sacred Kagura dances and festivals of Kirishima Jingu, the pilgrimages to the imperial tomb at Nitta Shrine, and the Jimmu accession festival at Miyazaki Jingu, the region maintains a multi-layered system of religion, performing arts, and festivals that carries ancient mythology into the present. The creation of modern regional brands like "Myths of Hometown Miyazaki" and "Kirishima Tourism" are prime examples of how ancient myths have expanded into modern regional revitalization, tourism industries, and educational materials. This is a rare instance of ancient mythology functioning as a living cultural resource spanning over two thousand years. Ninigi-no-Mikoto in the 21st Century ── Ancient Mythology and Modern Japan. In the 21st century, Ninigi-no-Mikoto and the Tenson Korin myth are preserved as material for ancient historical research, southern Kyushu tourism, Shinto rituals, and pop culture. Moving from political reinforcement under State Shinto before and during the war, to cultural relativization under the post-war separation of religion and state, and finally to multi-layered expansions in 21st-century tourism, subcultures, and education, the ancient myth maintains a strong continuity with modern Japanese spiritual culture. Continuously reimagined in subculture works like the games 'Okami' and 'Megami Tensei,' and the manga 'Demon Slayer,' the ancient Heavenly Descent myth bridges two millennia to continually drive the spiritual culture of 21st-century Japanese people. He is the symbolic deity of Japanese mythology, embodying the continuous thread of cultural inheritance from antiquity to the present.

Niutsuhime is the "god of the land" at the foundation of Mount Koya's religious landscape. Although the sacred site of Shingon esoteric Buddhism is known as the mountain of the Buddha (Dainichi Nyorai), its foundation is a land governed by local deities from before Kukai's arrival. The founding legend establishes the indispensable role of both Niu and Takano Myojin through a narrative of yielding this territory (dedication of divine land). The cinnabar indicated by the name "Niu" has been highly valued since ancient times as a mineral for preservation, warding off evil, and magic. The distribution of mercury veins at the foot of Mount Koya corroborates the existence of the Niu clan mining group and the deity they worshipped. Simultaneously, due to her location controlling the headwaters of the Kinokawa River, she is also revered as a water god, extending her protection to agriculture and irrigation. Under the syncretism of Shinto and Buddhism, she was considered a manifestation (suijaku) of the Womb Realm Dainichi Nyorai, and was enshrined in the Miyashiro and Amano-sha shrines within Mount Koya as the mountain's guardian. The romon gate and main sanctuary of the World Heritage Niutsuhime Shrine continue to convey that this goddess is the starting point of Mount Koya's 1,200 years of faith.

Oguchi-no-magami is not merely a beastly yokai, but the crystallization of a faith that enshrined the Japanese wolf—a real, apex predator of the mountains—as a "True God." Centered around Mitsumine Shrine in Chichibu, Musashi Province, and extending to sanctuaries like Musashi Mitake Shrine and Hodosan Shrine, it is a guardian deity that permeates the wolf-worshipping sphere of the Kanto region. Its essence lies in "purification and exorcism." The fire that attacks a house, the thief that sneaks in, the evil spirits that possess people—the divine nature of a "watchdog" capable of sniffing out and driving away unseen disasters was strongly sought after by the commoners of the early modern period. The unique practice of *Gokensoku Haishaku* is an intense form of faith where the deity itself is welcomed into the home for a year. Through repeated cycles of returning and renewing the amulet, the bond between the deity and the household is maintained. The fact that an extinct beast is still treated as a god today demonstrates the deep-rooted strength of this faith.

The many-named god and the gathering of local faith. The basic profile noted Okuninushi's many names; the deeper point is what such multiplicity means in religious history. Names such as Onamuchi, Okuninushi, Omononushi, Ashihara-shikoo, Yachihoko, Utsushi-kunitama, and Okunitama are often interpreted as traces of local land, agricultural, warrior, medical, and serpent cults absorbed into Okuninushi. When the Kojiki and Nihon Shoki were compiled in the early eighth century, the ritsuryo state needed a mythic structure that could relate central power to regional cults. The result was a paired mythology: the heavenly line of Takamagahara and Amaterasu, and the earthly line of Ashihara no Nakatsukuni and Okuninushi. The convergence of Izumo ritual lineages, Mount Miwa worship, and faiths from Inaba, Hoki, Koshi, Noto, Omi, and other regions makes Okuninushi a figure of religious, political, and geographic integration. The White Hare of Inaba as the origin of compassion and healing. The White Hare of Inaba is one of ancient Japan's most famous myths of compassion, medicine, and dialogue with animals. Washing the flayed hare in fresh water and applying cattail pollen can be read as a mythic form of herbal knowledge and ritual healing. The hare's prophecy that Yagamihime will choose Onamuchi rather than the powerful elder brothers presents an ethics of matchmaking: true connection comes not from force or appearance, but from inner compassion. This remains the ethical core of Izumo Taisha's matchmaking faith. Bonds are not random accidents; they are drawn by virtue. Trials in Ne no Katasukuni and the heroic descent to the underworld. Onamuchi survives Susanoo's trials in Ne no Katasukuni: the snake chamber, the chamber of centipedes and bees, and the field set on fire, all with Suseribime's help. In comparative mythology this belongs to the broad pattern of the hero's visit to the underworld, the overcoming of ordeals, and marriage to a woman from the other realm. Parallels are often drawn with heroic cycles such as Odysseus, Heracles, Sigurd, Nala, and Hou Yi. The Japanese version is especially striking because the trial comes from the father god, the marriage is with that god's daughter, and the hero leaves with both blessing and power, joining themes of patriarchy, generational succession, and otherworldly marriage. Land-making with Sukunabikona as a civilization myth. The joint work of Okuninushi and Sukunabikona forms a myth of civilization: medicine, agriculture, ritual healing, hot springs, and the techniques that make life possible. Sukunabikona is a tiny deity, said to be about the size of a thumb and clothed in a moth's skin, and he forms a sharp counterpart to the great land-lord Okuninushi. Myths of civilization around the world often pair figures of contrasting scale or character; they imagine culture as something born from cooperation. After Sukunabikona leaves for Tokoyo no Kuni, Omononushi appears and helps complete the land. The pattern suggests a world made not by one god alone, but through divine differentiation and collaboration. Kuniyuzuri as a religious expression of political integration. The yielding of the land translates the political integration of ancient central and regional powers into mythic form. Takamagahara presses its claim; Okuninushi consents; Izumo Taisha is built; he withdraws as lord of the unseen realm. This sequence is often read as a mythic reflection of the incorporation of Izumo's independent religious culture into the central ritsuryo order. The strength contest between Takemikazuchi and Takeminakata also links the story to Suwa worship and warrior-god traditions, showing how local cults were nested within the central mythic system. The legends of Izumo Taisha's immense ancient hall, forty-eight or ninety-six meters high, symbolize the extraordinary ritual compensation granted to Okuninushi after the yielding. Izumo Taisha and the faith of Kamiarizuki. Izumo Taisha, Kizuki Taisha, is one of ancient Shinto's great sacred centers, alongside Ise Jingu, and enshrines Okuninushi as its principal deity. The old tenth month is Kamiarizuki in Izumo, when the gods are present, and Kannazuki elsewhere, when the gods are absent. The belief that Japan's myriad gods gather in Izumo to discuss ties, destiny, and human affairs underlies the Kamiari Festival to this day. That ritual imagination supports Okuninushi's modern identity as god of matchmaking and fate. Even the contrast between "the month with gods" in Izumo and "the month without gods" elsewhere preserves an ancient religious geography in language itself. Daikokuten syncretism and Seven Lucky Gods worship. From the medieval period onward, Okuninushi merged with Daikokuten, the Buddhist Mahakala. The shared sound daikoku connected "great land" and "great black," allowing a land-making, healing, matchmaking deity to absorb the prosperity and mercantile power of early modern Daikokuten. As Seven Lucky Gods worship spread in the Edo period, Okuninushi entered popular life as Daikoku-sama, a god of flourishing trade, wealth, and harvest. Seen beside Benzaiten and the other lucky gods, he shows how ancient myth, early modern urban piety, and modern tourist religion remain linked across two millennia. Okuninushi in the twenty-first century: matchmaking and the Izumo brand. Today Okuninushi still draws enormous numbers of visitors as the principal deity of Izumo Taisha and as Japan's great god of relationships. His layers, matchmaking, healing, land-making, commerce, and fate, remain active in modern practices around marriage, life choices, business, divination, and travel. The "Izumo" image is built from all of these layers. Modern media, including games such as Okami and manga such as Demon Slayer, continue to reuse and reshape Izumo myth. Okuninushi is therefore a leading example of an ancient deity still narrated, visited, and consumed in contemporary culture.

The Master of Life's Eternity and Finitude. The myth wherein Oyamatsumi offers his daughters Iwanaga-hime (the eternity of rock) and Konohanasakuya-hime (the fleeting beauty of a blossom) to the Heavenly Grandson is not merely a marriage tale, but a philosophical myth determining human lifespan and natural providence. When Ninigi-no-mikoto chose only the beautiful younger sister and sent back the ugly older sister, Oyamatsumi delivered a declaration that was both a curse and a prophecy: "The lifespan of the Heavenly Grandson, which should have been eternal like a rock, will now scatter fleetingly like a blossom." He is depicted as a god with a cold, primordial fatherhood who teaches humanity both the beauty and harshness of nature, and the finitude of life. A Massive Perspective of Nature That Rejects Anthropomorphism. Among Japanese deities, rather than being depicted in a specific anthropomorphic form (such as an old man), Oyamatsumi is strongly perceived as a massive mountain block, a dense forest, or an island serving as a navigational landmark. This grand scale is the very perspective of mother nature, transcending the morals and ethics of human society. Even during the era of Shinto-Buddhist syncretism (Honji Suijaku), rather than being tied to a specific Buddha, he was worshipped as an overwhelming aggregate of natural energy. Guardian of Mines, Blacksmithing, and Brewing. The multifaceted nature of the mountain god expanded further. He was devoutly worshipped as a professional deity by miners who extracted ore from the mountains and by blacksmiths. Furthermore, he possesses the aspect of a god of brewing as "Sakatoke-no-kami." This stems from ancient memories of alcohol being brewed from wild nuts and spring water found in the mountains, and the indispensability of alcohol in rituals before the gods. Oyamatsumi is an all-powerful tutelary deity (Ubusunagami) who manifests on all boundary lines where nature's bounty is transformed into human culture (livelihood).

This is a bizarre visiting deity covered in mud and vines. It is said to chase villagers while glaring from beneath an expressionless mask, pressing muddy handprints onto them to drive away the year's misfortunes. Though its arrival is rough and chaotic, it brings both awe and blessings, as the mud it bestows is believed to grant protective power to people and their homes. Usually residing in the otherworld, isolated from the human realm, it only crosses the boundaries of the village on designated festival days, fully coated in the mud of the Spring of Birth. Its silent, plodding steps reflect its solemn duty as a deity of purification—taking the impurities and calamities of the people upon itself and bearing them back to the otherworld.

The definitive image of Raijin was established by Tawaraya Sotatsu's "Wind God and Thunder God Screens", a pair of two-panel folding screens with a gold-leaf background. It pits a white Raijin on the left (carrying a ring of connected drums on his back) against a green Fujin on the right (carrying a wind bag). This composition was faithfully reproduced by subsequent Rimpa school painters like Ogata Korin and Sakai Hoitsu, becoming the standard iconography for Fujin and Raijin today. The drums encircling Raijin's back are said to produce thunderclaps when struck; combined with his ogre-like form, tiger-skin loincloth, and sharp claws, this design visualizes the tempestuous forces of the sky. In the history of faith, Raijin can be broadly classified into three lineages. First is the classical thunder god represented by Kamo-wakeikazuchi-no-Okami (Kamigamo Shrine). Second is the Tenjin lineage, which conflates the vengeful spirit of Sugawara no Michizane with Karai Tenjin (Kitano Tenmangu, founded in 947). Third is Takemikazuchi, who bears "thunder" in his name but is essentially a sword and martial deity, and should not be equated with Raijin. In the Kanto region, Raiden worship spread outward from its headquarters at Raiden Shrine in Itakura, Gunma; it enshrines deities like Karai-no-Okami, Oikazuchi-no-Okami, and Wakeikazuchi-no-Okami as targets for prayers against lightning strikes and for bountiful harvests. In an agrarian society, lightning was seen as a harbinger of fertility—striking rice paddies to make the crops bear fruit as "inazuma" (literally "spouse of the rice"). Thus, Raijin has long been revered as a dual-natured entity: a terrifying deity who delivers heavenly punishment, and a benevolent god who brings the blessings of rain and harvest.

Ryujashin occupies a unique position as a "divine messenger" functioning within the specific ritual context of Izumo's Kamiari Festival. While general dragon gods (composite water deities governing water, rain, and the sea) are based on nationwide rain-making and rain-stopping beliefs, Ryujashin is strictly a functional deity acting as the guide for the eight million gods, limited to the Kamiari rituals of shrines like Izumo Taisha and Sada Shrine. Its essence is not an abstract concept of faith, but a real marine animal—the yellow-bellied sea snake—that actually washes ashore on the Izumo coast in late autumn. The perfect alignment of a natural phenomenon (warm-water sea snakes drifting on the Tsushima Current) with mythological time (the gathering of gods in the Kamiari month) forms the core of a rare seasonal ritual. The washed-ashore individuals are dedicated to the Grand Shrine, and through the Ryuja-ko of Izumo Taishakyo, it developed into an independent object of worship, with talismans distributed to the common people for protection against fire, water disasters, theft, and for good fortune. By visiting from the Eternal Land and the otherworld beyond the sea, it embodies the ancient worldview that saw Izumo as a passageway to the otherworld.

As the "water-god who stills the storm," Ryujin stands at the border of sea and sky holding the weather in his hands, and it was to him that fishermen, sailors, and the rice-growing folk of the villages prayed most urgently. His power cuts both ways. At times he grants the blessed rain that nourishes the paddies; at times he raises great waves and tempests that shatter ships. For this reason people approached him through many rites, hoping to calm his raging face and draw out his face of blessing. The greatest divine treasures the sea-dragon holds are the tide-flowing and tide-ebbing jewels that command the rise and fall of the tide. Hoori received these two jewels from the sea-god, drowning his elder brother with the flowing jewel and saving him with the ebbing jewel to force his submission. This power to govern the tide at will reveals the very essence of the dragon who rules the sea. At coastal shrines people prayed for storms to subside and for good catches; inland they prayed for rain, offering black horses in drought and sinking offerings into deep pools to court his favor. The legends of human sacrifice handed down at Lake Ashi and at ponds across the land share a single plot — a high priest subdues the raging dragon and turns it into a guardian — telling us that fear and reverence were two sides of one coin. His face as lord of the Dragon Palace is of a piece with this water-divinity. Beyond the sea, on the floor of the waters, the dragon's palace is an otherworld of riches and of time, and one who visits it either gains treasure or, like the one who opened the jeweled box, bears away years that can never be regained. Ryujin is no mere monster but a deity who embodies water itself — the very resource of life and death — and to still the storm was, in the end, to make people keep the fragile covenant drawn between humankind and nature.

This version of Sakanoue no Tamuramaro is not treated as the historical military official, but as the deified Tamura Daimyojin of later generations. He is told as a warrior receiving the protection of Kannon at Kiyomizu-dera, a paired husband-and-wife deity with Suzuka Gozen at Suzuka Pass, and as General Tamura subjugating Akuro-o and Otakemaru in Tohoku. A single person's name wandered through the temple origins of Kyoto, the mountain pass faith of Suzuka, and the shrine and temple origins of Tohoku, acquiring different faces in each land. The power of Tamuramaro is not the sword that slashes demons itself. Kiyomizu Kannon, Vaisravana, Suzuka Gozen, the sacred sword, and the gods of the passes support his story, transforming his martial prowess into "protection acknowledged by the gods and buddhas." Therefore, in the Tamura-gatari, rather than the scenes of defeating enemies, what matters more is which gods and buddhas took his side, in what land he was enshrined, and to which mounds or temples the memories were transferred. Sakanoue no Tamuramaro is a hero who defeats yokai, but at the same time, an axis to pass down yokai as stories to later generations.

In medieval Japan, the monkey deity was told as a fusion of mountain divinity and simian monster. It ruled mountain domains and demanded offerings like a calendar ritual, seen as a relic of ancient sacred marriage rites, yet storytelling emphasized its brutality as a yokai. In slaying tales, a passing hunter or a monk with sacred power stands in as a substitute, and a trained dog plays the decisive role. The defeated deity sometimes possesses a shrine official to beg forgiveness, hinting at lingering sanctity. In some regions it was known as a possessing spirit, with sudden rages blamed on its curse. Early modern ghost stories pair man‑eating ferocity with comic butt‑fondling, portraying the ambivalent scorn and fear directed at monkeys.

Special Position in Ancient Mythology as the 'Grotesque Guiding God'. While the basic description touches on Sarutahiko-no-Mikoto's main myth, this detailed explanation delves into his unique position as a 'grotesque guiding god' in ancient Japanese mythology. His bizarre appearance, with a nose seven ata long and eyes shining like the Yata-no-Kagami, is extremely visual and concrete even among the descriptions of deities in ancient myths, serving as the ultimate religious expression of 'a deity standing at the boundary between the otherworld and this world.' The fact that such a strong contrast between the noble Amaterasu-lineage deities and a grotesque Kunitsukami was placed at the core moment of the Tenson Korin, the central ancient Japanese state myth, can be interpreted as an intentional narrative device by the myth's compilers. Grotesqueness is not just visual oddity; it is the concrete embodiment of universal religious feelings such as protection from the otherworld, crossing boundaries, and reconciling with the heterogeneous. Prototype of the Tengu ── Development into Shugendo and Mountain Beliefs. Sarutahiko-no-Mikoto's grotesque description (long nose, red face, glowing eyes) is folklorically positioned as the prototype of the later Tengu (shugendo-related mountain yokai). The Tengu beliefs of the Heian and medieval periods inherited Sarutahiko's grotesque nature while intricately intertwining with Buddhism, shugendo, and mountain worship to undergo unique development. The hierarchical system of Tengu, such as Daitengu, Karasu Tengu, and Konoha Tengu, can be understood as the medieval refinement of the 'grotesque deity' originating from the ancient Sarutahiko. The relationship between Sarutahiko and the Tengu is a crucial genealogical theory in Japanese yokai studies, serving as core material for examining the continuity between ancient mythology and medieval yokai culture. Reconciliation and Cooperation between 'Amatsukami and Kunitsukami'. In the political and religious event of the Tenson Korin, where 'Amatsukami (deities of the heavenly realm) descend into the territory of Kunitsukami (deities of the earthly realm),' Sarutahiko-no-Mikoto stands out as a rare Kunitsukami who proactively welcomed the Amatsukami. In contrast to Okuninushi's yielding of the land, which was a 'forced transfer,' Sarutahiko's guidance occupies the contrasting position of 'voluntary cooperation.' This represents two aspects of religious integration between the center (Amatsukami lineage) and the periphery (Kunitsukami lineage) in ancient Japan. The contrast between forced integration (Okuninushi) and voluntary cooperation (Sarutahiko) reflects the editorial intent of the ancient state myths and the complex multiplicity of ancient Japanese political history. The Tragedy of the Hirabu-gai ── Vulnerability of the Deity and the Meaning of His End. The ending where Sarutahiko-no-Mikoto drowns after being caught by a hirabu-gai is a unique tale in ancient mythology that expresses the vulnerability of deities, human contingency, and the unknowability of fate. The ironic conclusion in which the great guiding god receives a fatal wound from a small natural object like a shell mythologizes universal themes in ancient Japan, such as 'confrontation with nature,' 'the limits of heroes,' and 'the unknowability of fate.' Furthermore, the specific circumstance of 'an accidental death while fishing' includes a religious reflection of marine, fishing, and coastal life in ancient Japan, symbolically demonstrating Sarutahiko's essence as a god standing at the boundary of sea and land, the intersection of life and death. The ending of the myth is not merely a tragedy but an advanced symbolic device that narrates the essential attributes of the deity. The Core of Doso-jin and Crossroads Deity Beliefs ── The Heart of Nationwide Folklore. From the Middle Ages onwards, Sarutahiko-no-Mikoto was widely venerated as the guardian deity of village boundaries, crossroads, mountain passes, and barriers through syncretism with Doso-jin, Funado-no-Kami, and Sae-no-Kami. The fact that Sarutahiko is positioned at the center of folk religion, such as Doso-jin stone monuments, phallic stones, crossroads Jizo, and Sae-no-Kami festivals distributed nationwide, demonstrates the continuous inheritance from ancient state myths to medieval folk religion. Doso-jin worship is not merely a religious ritual but a folkloric practice that gives meaning to universal anthropological themes of 'boundaries, new beginnings, protection, and harmony' through ancient myths. As a deity supporting the roots of Japanese people's sense of life, movement, and boundaries from ancient times to the present, Sarutahiko possesses a cultural reach that transcends a single deity appearing in a myth. Association with Koshin Belief ── Popular Religion in the Edo Period. During the Edo period, due to the phonetic association of 'Saru' (monkey) in Sarutahiko, he was linked to the Koshin belief (originating from Chinese Daoism, involving an all-night gathering every 60 days to defeat the Three Corpses), and Koshin towers, Sarutahiko Koshin mounds, and the three wise monkeys (see no evil, hear no evil, speak no evil) spread nationwide. This is a representative example of the multilayered fusion of ancient mythology, medieval Doso-jin, early modern Daoism, and Edo popular religion, demonstrating the typical Japanese religious culture of 'syncretism through phonetic association.' The combination of Koshin and Sarutahiko beliefs functioned as a core institution supporting the collective religious life, village society, and nighttime socializing of commoners in the Edo period, leaving traces in the modern landscape of the three wise monkeys and Koshin mounds. Sarutahiko-no-Mikoto in the 21st Century ── Modern God of Travel, Guidance, and New Beginnings. Today in the 21st century, Sarutahiko-no-Mikoto is widely cherished as the god of 'roads, travel, new beginnings, and guidance,' serving as an object of prayer for new car purchases, traffic safety, starting new businesses, safe travels, and major life milestones. Pilgrimages to Tsubaki Grand Shrine, Sarutahiko Shrine, and Futamiokitama Shrine continue ancient customs, and the religious structure of the ancient myth of 'visiting Amaterasu-Omikami under the guidance of the guiding god' has been inherited to this day. Even in a modern society marked by globalization, informatization, and individualization, the universal theme of 'life's paths, choices, and guidance' continues to impart new modern meanings to the ancient guiding god. As a rare deity whose presence bridges ancient mythology and modern Japanese spiritual culture for over two thousand years, he bears a living inheritance in religion, culture, and tourism in the 21st century.

In Japan it is understood as a foreign divinity-spiritoriginating in the Classic of Mountains and Seas and related encyclopedic interests. Imagery follows the key points of a human face upon an immense red serpent body, whose opening and closing eyes divide day from night and whose breathing brings seasonal winds and heat or cold. Confusion with the Torch Dragon appears in early modern commentaries, yet most introductions cautiously note textual loci and descriptive differences, and signs of domestic worship are scarce. Consequently, local rites, taboos, and oral lore are meager, with reception centered on reading, sketching, and use as an art motif. It is often cited as an example of incorporating a foreign divinity into yokai catalogues and is positioned as a personification of time and the seasons.

This edition follows, in close detail and bound to chronology and iconography, how a single man of letters became a thunder god and then turned into the god of learning—those two transformations. Michizane's becoming a vengeful spirit did not begin immediately upon his death. In the eighth year of Engi (908) his former disciple Fujiwara no Sugane died; the next year, the ninth of Engi (909), the very author of his exile, Fujiwara no Tokihira, died at thirty-nine; and in the twenty-third year of Engi (923) the crown prince Yasuakira passed away. That year the court restored Michizane to Minister of the Right and posthumously granted him the junior first rank, absolving him of guilt—yet the calamities did not cease, and in the third year of Enchō (925) even the next crown prince, Yoshiyori-ō, left the world at only five. The process by which this chain of deaths came to be felt by the people of the capital as the curse of the innocent Michizane is the very genesis of goryō belief. Its apex was the lightning strike on the Seiryōden in the eighth year of Enchō (930). The lightning that struck the palace in the midst of a rain-prayer council killed Fujiwara no Kiyotsura, who had watched over Michizane at Dazaifu, instantly, and burned the nobles present one after another. The reading of lightning as Michizane's will became decisive here, and the spirit, surpassing a mere vengeful ghost, was exalted into a dread godhead called Karai-Tenjin, Tenman Daijizai Tenjin, and Nihon Daijō Itoku-ten—a deity who commands the thunder. The Kamakura-period Kitano Tenjin Engi Emaki depicts this scene of becoming a thunder god as the masterpiece of the scroll, and the image of Tenjin driving the thunderclouds cast its shadow even upon the later wind-and-thunder-god paintings of Tawaraya Sōtatsu and others. The iconography of Tenjin has two contrasting lineages. One is the raging Fire-and-Thunder Deity of the engi scrolls, mounted on thunderclouds and hurling lightning. The other is the composed image of a man of letters and official in court robes holding a baton (shaku), accompanied by a plum at his side—and this became the standard image of the god of learning. The "Tang-crossing Tenjin" (Totō Tenjin), clad in Chinese robes, bearing a sack and holding a sprig of plum, is a variant based on a Zen monastic tale that Michizane crossed in a single night to a Song-dynasty Zen master to receive his teaching. The shift of weight from vengeful spirit to god of learning advanced gradually. Already in the mid-Heian period he was praised in ritual prayers as a merciful god presiding over letters and honesty, and in the fourth year of Shōryaku (993) the posthumous senior first rank and the office of Chancellor were conferred, fully restoring his honor. But his popular establishment as the god of academic success came far later, in the Edo period, with the spread of terakoya schools. The image of Michizane the outstanding scholar in life was hung in the places of penmanship, and as the guardian of reading, writing, and learning, Tenjin shed the dread of the thunder god and spread to Tenmangū shrines across the land.

This version digs into Suiko-sama as a faith that "raised a yokai all the way to a god." The kappa is by nature a fearsome creature that drags people into the water. The wisdom of the Tsugaru Suiko-sama cult lies in this: rather than slaying the kappa, it made the creature into a god who commands forty-eight of them as their head, entrusting it with the order of the waterside. The faith was bound tightly to the lives of children. The custom of offering cucumbers and floating them downstream in the river-playing season was at once a prayer to the deity and a way of impressing on children the everyday warning, "never let your guard down at the water." Benzaiten's form is borrowed for the sacred image because two water deities naturally merged into one. It shares only its kanji name with the ferocious "suiko" of the Chinese books; in substance the two are nothing alike. Suiko-sama is a water god in the manner of the snow country — one in which people reshaped the local dread of the kappa into an object of prayer. The specific rites and incantations vary greatly from district to district, and many have not survived to the present.

Sukunabikona is the "paired" deity who supported Okuninushi, the main god of Izumo Taisha, as his sole partner in nation-building. His divinity is fully realized not in isolation, but as one half of a pair with Okuninushi. The contrast between the massive earthly god (Kunitsukami) Okuninushi and his diminutive stature—small enough to ride in a milkweed pod boat—highlights their collaboration. His functions center on practical arts and civilization-building, such as medicine, incantations, agriculture, sake brewing, and hot springs. He left his mark beyond Izumo in the founding legends of hot springs like Dogo and Arima, as well as at Sukunahikona Shrine (the god of medicine in Doshomachi, Osaka), becoming a nationwide figure in medicine and hot spring worship. His departure, bouncing off a millet stalk to the Eternal Land, acts as the hinge connecting the myth to the arrival of Omononushi at Mt. Miwa, embodying the Izumo mythos structure where nation-building is achieved through the successive cooperation of multiple gods. His archetype of a small body with immense power is also the mythological origin of "tiny child" folktales like Issun-boshi.

The true identity of the Sumiyoshi Sanjin is the three kami of purification belonging to Izanagi-no-Mikoto, appearing in the first volume of the Kojiki (Age of the Gods). When Izanagi returned from Yomi (the underworld) and performed misogi (purification) at Ahagihara in Himuka of Tsukushi, he submerged himself in seawater to cleanse his body. From three different depths, three deities were born: recorded as 'Sokotsutsu-no-o-no-kami, Nakatsutsu-no-o-no-kami, Uwatsutsu-no-o-no-kami' in the Kojiki, and as 'Sokotsutsu-no-o-no-Mikoto, Nakatsutsu-no-o-no-Mikoto, Omotetsutsu-no-o-no-Mikoto' in the Nihon Shoki. The orthographic difference between 'Uwa' (upper) in the Kojiki and 'Omote' (surface) in the Shoki is one basis for the later interpretation of 'tsutsu' as layers of water. Simultaneously, the three Watatsumi kami (Sokotsu, Nakatsu, Uwatsu Watatsumi) were born, making Sumiyoshi and Watatsumi a paired dual structure—bottom = Sokotsutsu/Sokotsu Watatsumi; middle = Nakatsutsu/Nakatsu Watatsumi; surface = Uwatsutsu/Uwatsu Watatsumi. This tripartite structure is common to both texts. The etymology of 'Tsutsu' has not been academically resolved. Major theories are listed alongside each other: ① Star theory — 'Tsutsu' is an archaic word for 'star' (hoshi); it deifies the three central stars of Orion (ancient name 'Miboshi') as navigational stars for ancient seafaring clans. However, this is a modern theory advocated by Hoei Nojiri in "Japanese Stars" (1936), and there are no direct supporting primary texts from early folklorists like Orikuchi or Yanagita; treating it as the 'accepted folkloric theory' is academically inaccurate. ② Tsu (port) theory — 'Tsu' is a particle meaning 'of', and the second 'tsu' means 'port/sea route', an interpretation from Orikuchi's lineage; ③ Tsuchi phonetic change theory — 'Tsu' is a particle, and 'chi' is an honorific spirit suffix (akin to Orochi or Nozuchi); ④ Tsutsu-ro theory — 'Tsuchi' equals 'tsuji' meaning sea route; ⑤ Ship spirit theory — ancient ship spirit worship enshrined at the bottom of a boat; ⑥ Tsutsu toponym theory — derived from Tsutsu at the southern tip of Tsushima, the origin of seafaring clans; ⑦ Literal tube theory — using bamboo tubes as a yorishiro (vessel). Listing multiple theories is academically accurate, and it is particularly imprecise to refer solely to the 'star theory' as the accepted view. The Empress Jingu legend is the most important narrative in the history of Sumiyoshi Sanjin worship. According to the Nihon Shoki, when Empress Jingu became possessed after Emperor Chuai's death, the Sumiyoshi kami delivered an oracle: "Conquer Silla, a land filled with gold and silver. If you worship us three deities, Silla and Kumaso will submit." They protected her maritime expedition (subjugating Silla, Baekje, and Goguryeo), and upon her return, a second oracle commanded: "Enshrine our Aramitama (rough spirit) in Yamada village of Anato (Nagato)" — this became the origin of the Shimonoseki Sumiyoshi Shrine. Enshrining the Nigimitama (gentle spirit) in Settsu became the origin of Sumiyoshi Taisha. The structure of jointly enshrining Empress Jingu and Sumiyoshi Sanjin originated here, establishing the unique four-hall structure of Sumiyoshi Taisha. However, the dating of the Empress Jingu chronicles is heavily debated by scholars, and treating the legendary date (211 AD) as historical fact requires extreme caution—archaeologically, it is pointed out as potentially reflecting events from the 4th century onwards. Sumiyoshi Taisha, the head shrine (2-9-89 Sumiyoshi, Sumiyoshi-ku, Osaka), is the Ichinomiya of Settsu Province, one of the Twenty-Two Shrines (Middle Seven Shrines), and a former Kanpei-taisha. Its official history dates its founding to the 11th year of Empress Jingu's regency (211 AD) on the first Day of the Hare in the Month of the Hare — a legendary date without archaeological proof. Its four main halls have a unique layout: the First, Second, and Third Halls line up vertically (facing west, toward the sea), while the Fourth Hall sits south of the Third, forming an L-shape. The First Hall enshrines Sokotsutsu-no-o, the Second Nakatsutsu-no-o, the Third Uwatsutsu-no-o, and the Fourth Empress Jingu. "Sumiyoshi-zukuri" is considered the oldest style in shrine architectural history, characterized by a gabled roof, cypress bark thatch, and red and white walls. The current main halls were built in 1810 and are all designated National Treasures. The steeply arched red Sorihashi (Taiko Bridge) is the iconic visual symbol of the Sumiyoshi faith, frequently appearing in ukiyo-e, paintings, and waka poetry. There are over 2,300 branch shrines nationwide (the official number from Sumiyoshi Taisha, whereas Wikipedia undercounts at ~600). The distribution is concentrated along coastlines, ports, the Seto Inland Sea, Kyushu, and northern Japan, proving it to be the most vital faith for fishermen, shipping merchants, and navy personnel from ancient to modern times. The "Three Great Sumiyoshi" and ancient shrine dispute: ① Sumiyoshi Taisha (Osaka) = Settsu Ichinomiya, Nigimitama, Head Shrine; ② Sumiyoshi Shrine (Shimonoseki, Yamaguchi) = Nagato Ichinomiya, Aramitama, site of Empress Jingu's return oracle; ③ Sumiyoshi Shrine (Hakata, Fukuoka) = Chikuzen Ichinomiya, self-proclaimed "Japan's First Sumiyoshi-gu", oldest theory identified with Ahagihara. Additionally, Hon-Sumiyoshi Shrine in Kobe is based on an influential Edo-period theory by Motoori Norinaga (1764-1798) identifying Settsu's Sumiyoshi village as the ancient "Nanakura's Long Strait". Academically, the "first Sumiyoshi" cannot be determined, with each shrine claiming primacy based on its own legends. In ancient and medieval times, it was customary for Japanese envoys to Sui and Tang China to pray at Sumiyoshi Taisha before departing. The "Tosa Nikki" (Ki no Tsurayuki, 935) also notes prayers for maritime safety to the Sumiyoshi deities. In Heian-period waka by poets like Izumi Shikibu, Ki no Tsurayuki, and Ono no Komachi, Sumiyoshi frequently appears, positioning the kami at the head of the "Three Deities of Waka". In the medieval and early modern periods, the Noh play "Takasago" featured the "Pines of Sumiyoshi and Takasago" as a symbol of marital harmony and longevity, often performed at shrine weddings. The Noh play "Sumiyoshi Mode" is another masterpiece representing this faith. The rice-planting ritual (Otaue Shinji), a National Important Intangible Folk Cultural Property, is Sumiyoshi Taisha's most representative festival, sanctifying the entire rice-farming cycle from planting to harvest. As a samurai faith from the medieval to Edo periods, they garnered reverence from warrior clans like the Minamoto due to Empress Jingu's Sankan Seibatsu legends. During the Muromachi and Sengoku periods, Sumiyoshi Taisha received immense veneration from the shipping industry in the Seto Inland Sea, Settsu, and Izumi, actively participating in both commercial and military affairs as the guardian of maritime traffic in Osaka Bay. Today, visits by the Maritime Self-Defense Force, merchant ships, fishermen, and shipping businesses remain robust. It is one of Osaka's premier spots for New Year's visits, Shichi-Go-San, and shrine weddings. Affectionately called "Sumiyoshi-san" in the Kansai region, the Sumiyoshi Sanjin are a national divine presence offering wide-ranging blessings for maritime protection, safety at sea, poetry, scholarship, marital harmony, safe childbirth, and business prosperity. The 2,300 branch shrines, known as Sumiyoshi Shrine, Sumiyoshi-sha, Sumie Shrine, or Sumiyoshi Jinja, line Japan's coastlines and ports, forming the backbone of an uninterrupted maritime faith from ancient times to the present day.

The Dramatic Transformation from 'Wild God' to 'Hero God'. While the basic description traced Susanoo's primary myths, this detailed explanation delves into his dramatic personality shift from 'wild god' to 'hero god'. The Susanoo of the Kojiki and Nihon Shoki possesses diverse characteristics, having three entirely different aspects: the childishness of weeping for his mother, the ferocity in Takamagahara, and the heroism, paternity, and wisdom in granting trials after descending to Izumo. Folklorist Teiji Yoshimura (1977) pointed out that 'the Susanoo of Takamagahara mythology and Izumo mythology have different personalities.' This can be interpreted as the result of multiple different mythological traditions being integrated into a single deity. Two lineages—the Takamagahara mythological sphere (Amatsu-kami lineage) and the Izumo mythological sphere (Kunitsu-kami lineage)—were converged into the single deity 'Susanoo' during the process of political and religious integration in ancient Japan, resulting in a unique deity with a multi-layered personality. Yearning for the 'Mother's Country' ── Ancient Motherhood Beliefs. Despite being entrusted with the rule of the sea plain by his father Izanagi, Susanoo continued to weep and howl in longing for the root country (Ne-no-Katasu-Kuni) of his deceased mother Izanami. This 'yearning for the Mother's Country (Hahanokuni)' is an important motif in ancient Japanese mythology, expressing the fundamental tension among patriarchy, matriarchy, and generational succession. Shinobu Orikuchi deciphered this motif comparatively as 'Tokoyo-no-Kuni belief' and 'Mother's Country belief'. The later tale of Okuninushi descending to Ne-no-Katasu-Kuni to undergo Susanoo's trials also reflects the structure of generational succession: 'deceased mother → father god (Susanoo himself) → son-in-law god (Okuninushi)'. It can be read as a multi-layered expression of ancient Japanese views on motherhood, fatherhood, and life and death, transcending a simple heroic myth. Soshimori in Silla and Ancient Japan-Korea Relations. The Kojiki's account that the banished Susanoo descended to Mount Torikami in Izumo via 'Soshimori in Silla (Shiragi Soshimori)' is extremely interesting as a rare 'tale via the continent' in ancient Japanese mythology. The specific location of Soshimori in the southeastern Korean Peninsula is debated, and it can be interpreted as a passage mythologizing ancient Japan's history of continental immigrant culture and exchanges with the Korean Peninsula. It has been pointed out that Shinto of the Izumo Kuni-no-Miyatsuko lineage likely developed within the maritime trade network with the Korean Peninsula and the continent since ancient times, and Susanoo's tale via Silla can be read as a memory layer mythologizing this history of maritime exchange. It serves as documentary evidence showing that ancient Japan was not an isolated cultural sphere but formed through close interaction with the continent and peninsula. Social Historical Interpretation of Slaying Yamata-no-Orochi. The tale of slaying Yamata-no-Orochi has been interpreted as a multi-layered story reflecting the socio-historical situation of ancient Japan, going beyond a simple heroic monster-slaying myth. The specific descriptions—'eight heads, eight tails, along the Hii River, blood flowing from the belly, an iron sword from the tail'—strongly support the 'iron-making origin theory' (proposed by Takeshi Matsumae, Shohei Mishina, etc.), which suggests that the ancient Izumo tatara iron-making, the iron content of the Hii River, river flooding, and the social organization of iron-making communities were mythologized. Susanoo's heroic tale was formed in intense dialogue with the iron culture of ancient Japan and the nature and society of the Hii River basin, re-evaluated not as a simple myth but containing valuable record layers of ancient social history. 'Eight Clouds Arise' ── Japan's Oldest Waka. The poem Susanoo composed when he built a palace in Suga, Izumo after slaying Yamata-no-Orochi—'Eight clouds arise, the eightfold fence of Izumo creates an eightfold fence to keep my wife in, oh that eightfold fence'—is positioned as the origin of the history of Japanese literature and waka. The basic format of the thirty-one syllables (5-7-5-7-7) was already established here, demonstrating the identification of the birth of songs with mythological heroism in ancient Japan. The fact that the starting point of the entire Japanese waka culture, leading to the Man'yoshu, Kokinshu, and Shin-Kokinshu, is attributed to the mythic hero-god Susanoo symbolizes the inseparability of poetry and mythology in Japanese culture. The opening phrase 'Eight clouds arise' remains a sacred cultural resource repeatedly cited in the world of waka and tanka today. Syncretism with Gozu Tenno and Medieval Gion Beliefs. From the Middle Ages onward, Susanoo syncretized with Gozu Tenno, derived from Buddhism, Taoism, and the Korean Peninsula, becoming the guardian deity of dispelling epidemics and warding off disasters as the principal deity of the Kyoto Gion Shrine (now Yasaka Shrine). Gozu Tenno is considered a plague god originating from Silla and the Korean Peninsula, and has a complex religious history where Chinese beliefs of the guardian deity of Jetavana Monastery and Japanese Susanoo beliefs syncretized in the Middle Ages. The history of the Gion Goryo-e, initiated in 869 (Jogan 11) to pray for the end of an epidemic spreading in the capital, exceeds a millennium, and was inherited as the largest religious festival for dispelling epidemics nationwide throughout the Edo period, early modern, and modern eras. It continues to be inherited in the 21st century as the Kyoto Gion Festival (a nationally designated Important Intangible Folk Cultural Property) and a UNESCO Intangible Cultural Heritage, showing that the multi-layered overlap of ancient myth and medieval Buddhism continues to exert a sustained influence on the religious life of modern Japan. Resurgence in Modern Culture. Susanoo has been repeatedly re-sculpted in post-war Japanese subculture works. He frequently appears as one of the strongest demons in the 'Megami Tensei' series, in the portrayal of Susanoo and Kushinadahime in the game 'Okami', as a motif like 'Sun Breathing' in the manga 'Demon Slayer', and in anime such as 'Nura: Rise of the Yokai Clan' and works like 'Touhou Project'. His multi-layered attributes as a 'wild god', hero, ancestor of poetry, and guardian deity against epidemics have high affinity with modern character creation. He is a symbolic figure of ancient mythology who continues to drive the mythological imagination of the Japanese people for over two thousand years.

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.
