Yokai Encyclopedia

The true identity of Iwanaga-hime is the daughter of Oyamatsumi appearing at the end of Volume 1 of the *Kojiki* and in the 9th stage of the Age of the Gods in the *Nihon Shoki*. She is written as "Ishinaga-hime" in the *Kojiki*, and "Iwanaga-hime" in the *Nihon Shoki* and *Sendai Kuji Hongi*, with theories also equating her with Kokemusuhime and Konohana-chiru-hime. According to the semantic interpretation by Kokugakuin University's Classical Culture Project, her divine name means "a woman as eternal, steadfast, and enduring as a rock (Iwa)"—clearly designating her as a goddess symbolizing immortality, longevity, firmness, and solidity. Positioned alongside her younger sister Konohana-no-sakuya-bime as the two daughters of Oyamatsumi, she forms the core of contrast structures: "rock vs. flower," "eternity vs. transience," "solidity vs. beauty," "immortality vs. short life," and "rejected older sister vs. accepted younger sister." The core of her narrative lies in the myth of the heavenly descent (Tenson Korin) found at the end of Volume 1 of the *Kojiki* and the 9th stage of the *Nihon Shoki*. After Ninigi-no-Mikoto (the heavenly descendant) descended to Takachiho in Hyuga, he met the beautiful Konohana-sakuya-hime at Cape Kasasa and proposed to her father Oyamatsumi. The father was overjoyed and presented both the older sister Iwanaga-hime and younger sister Sakuya-hime with many tributes. However, Ninigi rejected Iwanaga-hime for her ugly appearance, sending her back and marrying only Sakuya-hime. Oyamatsumi's lament became the story's climax—in the *Kojiki*: "If you had let Ishinaga-hime serve you, the lifespan of the heavenly descendants would have been eternally immovable like a rock; but because you kept only Sakuya-hime, your life will be short like the flowers of trees" (lifespan shortened due to the failure of Oyamatsumi's oath); in the *Nihon Shoki*: "Shortened lifespan caused by the curse of the unaccepted Ishinaga-hime" (a more direct causality). Though slightly different, both accounts serve as the origin myth for the shortened lifespans of humans and the imperial line, forming the foundation of Japan's indigenous view of life and death before Buddhism. Comparative mythologist Tarō Ōbayashi classified this tale of contrast between Iwanaga-hime and Konohana-sakuya-hime as a Japanese variant of the "banana-type myth" (a tale of choosing between a stone and a banana). Belonging to the same lineage as the origin myth of death from Sulawesi, Indonesia (where humans chose a delicious banana over a stone, losing eternity to gain a short life that withers in one generation), it is the Japanese equivalent of universal origin of death myths like the Book of Genesis (expulsion from Eden) or Greek mythology (Pandora's box). Among her shrines, Kumomi Sengen Shrine (Kumomi 386-2, Matsuzaki, Shizuoka) garners attention in Shinto history and folklore studies as a rare shrine among the approximately 2,000 Sengen shrines nationwide that exclusively enshrines Iwanaga-hime. Sitting atop Mount Eboshi (elevation 162m), an ancient legend (recorded in the late 18th-century *Kojiki-den*) says, "When Mount Eboshi is clear, Mount Fuji is cloudy," historically identifying it as the older sister's seat in contrast to Sakuya-hime's Fuji. It was rebuilt in 1657, with its original founding unknown. Hoshoishi Shrine (Mikumo, Itoshima, Fukuoka) in the center of Ito-koku is an ancient shrine enshrining both sisters (recorded in the 1695 *Hoshoishi Shrine Engiki*). This rare sister-pair worship suggests a connection between imported continental culture and the Iwanaga-hime faith, given Ito-koku's role as ancient Japan's gateway to the continent. Shiromi Shrine (Shiromi, Saito, Miyazaki; former Nishimera Village area) enshrines three deities: Iwanaga-hime, Oyamatsumi, and Prince Kaneyoshi (of the Nanboku-cho period), founded in 1489 with its original sanctuary built in 1675. Its sacred object is a "silver mirror"—a place-name origin legend claims the mirror Iwanaga-hime threw in despair over her looks caught on a tree on Mount Ryubo, changing "Shiromi Village" to "Silver Mirror (Shiromi) Village." As a symbolic equivalent to rock, the mirror shows the unique syncretism of Iwanaga-hime's rock worship and mirror deity worship. The 33-part Shiromi Kagura dedicated every December 12-16 is a National Important Intangible Folk Cultural Property, representing the pinnacle of Kyushu folk performing arts as the primary stronghold for modern Iwanaga-hime veneration. Yui-no-Yashiro (Middle Shrine) of Kifune Shrine in Kyoto has been deeply worshiped for matchmaking since before the Heian period. Originating from the paradoxical legend that Iwanaga-hime hid in Kibune out of the shame of rejection, declaring "I will bestow good matches upon the people," she has been worshiped as "a god who does not sever ties, making them endure." The literary foundation for this matchmaking divinity is the story of Heian poet Izumi Shikibu (978?-1041?), who prayed here during marital strife and achieved reconciliation after dedicating a famous firefly poem. This paradoxical faith structure, linking the rock (a symbol of eternal immobility) with "enduring relationships," has continued unbroken from the Heian era to today. In folk beliefs, Mount Omuro in Izu (elevation 580m) is seen as her incarnation, carrying a sympathetic superstition that "praising sister Fuji while climbing Mount Omuro brings curses of injury or poor fishing"—a classic example of folk empathy for the "rejected ugly sister." Furthermore, Mount Tsukuba's Gessuiseki Shrine (Tsukuba, Ibaraki) enshrines an Iwakura where Iwanaga-hime reportedly died, showcasing the blending of ancient Japan's rock worship with her divinity. At Oyamatsumi Shrine's precinct shrine, Anaba Shrine (Omishima, Imabari, Ehime), she is enshrined with her father Oyamatsumi, preserving the origin of father-daughter worship. Today, since Mount Fuji's World Heritage registration (2013), Kumomi Sengen Shrine and Mount Eboshi have become tourist destinations. Additionally, as the "sister rejected by beauty standards," she resonates with modern female readers, advancing a feminist re-evaluation. Frequently reappearing in modern media with themes of "immortality/solidity," "kindness behind ugliness," and "matchmaking," the modern reinterpretation of this ancient myth continues to evolve.

Adheres strictly to Toriyama Sekien’s image and notes, avoiding later embellishments. The yokai is shown as the back view of a young woman standing by water, while the surface reflects the visage of an old man. The name draws on Dongfang Shuo’s “kaizai” expressions of wonder, suggesting Sekien likely fashioned an allegory. Youth and age, beauty and ugliness, front and back are opposed within a single frame, read as a design warning against being deceived by appearances. Firm oral traditions are scarce, so its character is defined largely through image interpretation. The readings iyaya or iyami vary by source, possibly evoking refusal or repulsion akin to “no,” but the literature offers no certainty.

The Seven Generations of the Gods and the cosmology of creation. The basic account covers land-birth and god-birth. Looking more closely, the Seven Generations of the Gods form a creation sequence in their own right. The Kojiki says that after heaven and earth open, the three creator deities and the Separate Heavenly Deities appear, followed by the divine generations beginning with Kuni-no-tokotachi. The line moves from solitary, abstract deities toward paired gods, then finally reaches Izanagi and Izanami as husband and wife. Myth moves from abstraction into relation, sex, marriage, and birth. Their marriage and the birth of the land are the decisive passage from divine potential into a concrete world. The Floating Bridge, the jeweled spear, and Onogoro Island. The scene in which the two gods stand on the Floating Bridge of Heaven and stir the sea with Ame-no-nuboko is one of the most important images in ancient Japanese cosmology. The bridge joins heaven and earth as a vertical world axis. The spear is an instrument of creation. Brine hardening into an island marks the passage from liquid to solid, from formlessness to form. Onogoro Island means something close to an island that congealed by itself, suggesting that creation is not only divine command but also natural self-formation. The scene can be read beside Pangu's separation of heaven and earth, the Indian cosmic egg, and Eurasian myths of stirring primordial waters. The descent to Yomi, an early East Asian Orpheus myth. Izanagi's descent to Yomi, his broken taboo, and his flight from the dead belong to the mythic type in which someone enters the underworld to recover a lost wife and fails after violating a prohibition. The Greek story of Orpheus and Eurydice is the most famous example, while Izanagi's version, written in the Kojiki in 712, is one of East Asia's earliest textual witnesses to the type. The stolen glimpse, the broken command, the pursuing dead, and the protective peaches all echo underworld narratives from India, China, and Europe, suggesting deep affinities across ancient Eurasian religious imagination. Misogi, the origin myth of Shinto purification. After escaping Yomi, Izanagi washes away its pollution at Awagihara. This is the origin myth of misogi and harae. Gods are born as he removes garments and objects from his body; sea deities are born as he washes in the stream; finally, the highest deities emerge from his eyes and nose. The structure binds body, impurity, purity, and divine birth together. The hand-washing before shrine worship, the Nagoshi no Oharae summer purification, and ritual ablutions before major ceremonies all find a mythic source here. Eda Shrine and Izanagi Jingu honor him as the ancestral deity of purification, showing how an ancient myth continues inside living Shinto practice. The Three Precious Children and ancient Japan's cosmic order. Izanagi divides the sky, night, and sea among the Three Precious Children. Amaterasu Omikami receives Takamagahara, the realm of heaven, daylight, and light. Tsukuyomi no Mikoto receives the realm of night, quiet, and calendrical rhythm. Susanoo no Mikoto receives the sea plain, the ocean and its violent force. This threefold division is not only a mythic plot point. It later supports the legitimacy of the imperial line and Ise Shinto. Medieval, early modern, and modern political thought in Japan repeatedly return to this narrative. It is a central line running through Japanese ideas of state, religion, and cosmic order. Taga Taisha, Izanagi Jingu, and Eda Shrine. The three major sacred places of Izanagi correspond to different moments in the myth. Izanagi Jingu in Awaji marks the beginning of land-birth, the marriage of the two gods, and Izanagi's hidden palace. Eda Shrine in Miyazaki marks Awagihara, purification, and the birth of the Three Precious Children. Taga Taisha in Shiga became a popular early modern shrine of long life and vitality. Together these sites turn the sequence of creation, purification, and longevity into geography and pilgrimage, sustaining Izanagi worship across Japan. Motoori Norinaga's Kojiki-den and the formation of kokugaku. Motoori Norinaga, the Edo-period kokugaku scholar, completed the forty-four-volume Kojiki-den in 1798, using rigorous philology and historical linguistics to interpret the Kojiki, including the myths of Izanagi. Debate continues over whether such myths should be read as history, symbolic narrative, or cultural memory, but Norinaga's method laid an important foundation for modern Japanese humanities. Izanagi therefore extends beyond myth alone. He belongs to the intellectual history of kokugaku, Shinto, modern national thought, and postwar folklore studies, and remains a symbolic figure in Japanese religion, scholarship, politics, and culture.

The cycle of birth and death: the nature of an ancient mother goddess. The basic profile described Izanami's mythic role; the deeper issue is that she embodies birth and death in a single archaic mother figure. Izanami gives birth to the Oyashima islands and thirty-five nature deities, and even on her deathbed continues to produce gods of mines, earth, and grain from her vomit, urine, and excrement. This resembles the ambivalence of mother goddesses across the ancient world, such as Gaia in Greece, Inanna in Sumer, or Kali in India: the one who gives life also contains death. Izanami is more than a creator deity. She joins birth and death, the living world and the underworld, purity and pollution into one Japanese variation of the archaic mother goddess. Kagutsuchi's birth and the symbolism of fire. Izanami dies because she gives birth to the fire god Kagutsuchi, an event of major symbolic force in ancient Japanese cosmology. Fire begins civilization: forging, pottery, cooking. Yet fire also brings destruction and death. In ancient societies, childbirth itself could threaten a woman's life, and the myth binds those dangers together. Kagutsuchi is born, Izanami dies, and from her dead or dying body arise deities of mines, earth, and grain. This chain makes the material foundations of civilization, metallurgy, agriculture, land-making, emerge from the sacrifice of the mother goddess. The myth gives a stark expression to an ancient worldview: civilization stands on the body of the mother. Yomi no Kuni and the queen of the dead. After burial, Izanami reigns as queen of Yomi no Kuni. This is an unusual structure in ancient myth. Chinese underworlds are often ruled by male figures such as Fengdu or the Lord of Mount Tai; India has Yama, and Greece has Hades. In Japanese myth, however, the realm of the dead is ruled by the former creation goddess. Izanami's rule over Yomi shows the close ancient Japanese linkage of woman, death, and underworld. Later images of Enma, Jizo, and the Sanzu River grow in soil prepared by this imagination of the dead. The idea of death as a feminine principle is one of the most striking points for comparative religion. The burial debate: Izumo and Kumano. The Kojiki names Mount Hiba, on the Izumo-Hoki border, as Izanami's burial place, while a variant in the Nihon Shoki names Kumano in Kii. The two traditions map onto two religious geographies. The Izumo line, Shobara in Hiroshima, Yasugi in Shimane, and Higashi-Izumo in Matsue, connects with Izumo ritual lineages and faith in Ne no Katasukuni. The Kumano line, Hana no Iwaya in Mie and Kumano Hayatama Taisha in Wakayama, connects with Kumano Sanzan worship, Fudaraku sea-crossing beliefs, and Pure Land imagination. Izumo lies to the north, facing the Sea of Japan; Kumano lies to the south, facing the Pacific. Together the two burial traditions form a core problem in the religious geography of ancient Japan. Hana no Iwaya Shrine and ancient iwakura worship. Hana no Iwaya Shrine in Kumano, Mie, is named in the Nihon Shoki as Izanami's burial place and is one of Japan's oldest shrines; it has no shrine hall and worships a forty-five-meter sacred rock as its divine body. Iwakura worship is an old Japanese mode of nature veneration in which trees, boulders, waterfalls, and mountain peaks are treated as places where divine spirits dwell. Later shrine architecture grew out of such natural sacred places, and Hana no Iwaya preserves an especially ancient layer by having no main building. The Otsunakage rite, held on February 2 and October 2, hangs a rope about 170 meters long from the sacred rock to the precincts; it is a rare living folk practice that carries ancient rock worship into the present. "One thousand a day, fifteen hundred a day": the cosmology of life and death. The exchange at Yomotsu Hirasaka is the moment when Japanese myth fixes the order of life and death. Izanami says she will kill one thousand people a day; Izanagi answers that he will cause fifteen hundred to be born. The scene is grief after marital separation, but also a cosmic declaration that death and life, underworld and this world, feminine and masculine principles will stand in permanent tension. Death counts one thousand; birth counts fifteen hundred. Life exceeds death. That inequality becomes a religious expression of life's continuation. Japanese myth does not remain a simple tragedy; it turns the dialectic of life and death into cosmology. Izanami reevaluated in the twenty-first century. Postwar feminist myth studies and cultural criticism have moved beyond reading Izanami only as a victim of patriarchal myth. They also understand her as an embodiment of the ancient mother goddess who unites birth, death, and the underworld. Motoori Norinaga's Kojiki-den, completed in 1798, laid the philological foundation; later comparative mythologists such as Orikuchi Shinobu, Obayashi Taryo, and Yoshida Atsuhiko added new interpretive layers. In the twenty-first century, Izanami is no longer merely a mythic character. She has become an image of the feminine root of Japanese myth and of cosmic order as mother, continuing to shape religion, scholarship, and cultural imagination.

Izutamahiko no Mikoto is a rare deity whose existence traces three stages of elevation: originally a real high-ranking monk, Kongobo Yusei (the fourth head of Konkoin, died 1613), who became a tengu and guardian spirit after death, and was finally redefined as a Shinto deity during the Meiji era's separation of Shinto and Buddhism. While the principal deity Konpira (Omononushi) originates from a foreign water god (Kumbhira) and presides over "maritime protection," Izutamahiko no Mikoto embodies the lineage of "mountain asceticism and tengu worship." The dual structure of the Mount Zozu faith—where a god of the sea and a tengu of the mountain reside together—is demonstrated through the relationship between the principal deity and the deity of the Okusha (Inner Shrine), making this deity highly significant in religious history. The Okusha, Izutama Shrine, sits at an altitude of 421 meters, 1,368 steps away from the main shrine, and is considered the second holiest site of Kotohira-gu.

This version organizes the image of the Jami as an example of Sekien aligning a Chinese-origin demonic concept within Japan’s yokai system. Its original sense is “pernicious enchantment,” classed among chimi, a noxious presence born from the gloom of mountains and wastelands that harms body and mind. Its form is not fixed in classical texts, and images function more as visualizations of an idea. The effects fall between illness and invisible curse—fever, hallucination, frenzy—sometimes triggered by contact with resentment or defilement. Countermeasures include bans, talismans, and wards; traditions speak of drawing a prison on the ground to summon and seal, binding it by asking its name, or transferring it into a vessel. In Japan it rarely became an object of distinct cult, often treated as a generic term alongside more-ryo. In folk terms it is distinguished from miasma, mononoke, and tsukumogami, a high-abstraction yokai appearing where the chill of wild places intersects with human grudge.

This version of Empress Jingu is read not as an introduction to a historical figure, but as a body that receives divine oracles. In the scene where divine will descends before Emperor Chuai, the empress is not merely a consort, but a vessel through which the voice of the gods passes. In ancient kingship, politics and ritual were not separated. Her decisions were simultaneously military actions and rituals executing divine will. The mythological nature of the Three Han conquest tale is the core of this version. The plot of crossing the sea while pregnant, delaying childbirth with a stone, and returning to give birth to Emperor Ojin seems bizarre from a modern realistic perspective. But viewed as myth, it is the story of a woman carrying a future king in her womb, crossing the outer seas under the protection of the gods. The mother's body itself becomes the ship carrying the nation's future. The sweetfish fishing at Matsura is important as a scene that grounds her myth to the land. Within the large-scale expedition tale, a subtle action of fishing at Tamashima village to divine fortunes is included. Here, Empress Jingu becomes a shamanistic figure reading waterside omens, concurrently with being the protagonist of a maritime military myth. Grand epic and minute folklore overlap in the same person. Empress Jingu in the Hachiman belief is not only the mother of Emperor Ojin but a deity supporting Hachiman's spiritual authority. When the Hachiman god spreads as the protector of the samurai, there is an underlying complex structure of mother and child, oracles and military, maritime transport and national protection. Extracting the empress alone, severing the relationship lines with Hachiman and the three Sumiyoshi deities, halves her power. To visualize this version, an armored queen alone is insufficient. The forest of Kashii, the rough sea, the divine majesty of Sumiyoshi, the prince in her womb, the caught sweetfish, the expedition fleet. By layering these elements, Empress Jingu emerges not as a fighting woman, but as a presence imbued with mythological kingship. In modern diagnoses and articles, Empress Jingu becomes a symbol of the "power to bear a role." Her story resonates strongly when one must accept a massive flow even if undesired, or when one must proceed while holding what must be protected in the womb or heart. However, it requires the honesty to treat her not as a historical fact, but as a deity created by the Kiki myths and shrine beliefs. The terror of Empress Jingu lies in divine will larger than personal emotion passing through her body. One who receives an oracle is simultaneously bound by it. She is not a hero adventuring freely, but an existence pushed forward by the gods and the future of kingship. Including that weight ensures the legend is not merely a tale of victory. The relationship with Emperor Ojin is the most crucial line connecting Empress Jingu to the Hachiman belief. The prince residing in her womb is at the center of the story even before birth. The mother's expedition, the gods' protection, and the birth upon return connect to prepare the sacredness of the Hachiman god. The empress is the entity that carries Hachiman's prehistory within her body. Furthermore, Empress Jingu is a deity that moves locations. Place names like Kashii, Matsura, Sumiyoshi, and Usa hold meaning in the story, each remaining as modern sites of worship. Linking this with YOKAI.JP's place articles allows one to walk the actual geography while reading the myth. There is practical value in adding this page there.

This form is based on the block-printed wording copied into Katō Eibian's Waga Koromo. Jinja-hime has a human face, two horns, a crimson belly, and a tail ending in three swordlike points. It appears on the shore as a messenger from the Dragon Palace and announces that abundant harvests will be followed by epidemic disease. Printed notices claimed that pasting Jinja-hime's likeness at a doorway, or viewing the image with devotion, could avert calamity and prolong life. As woodblock prints and hand copies circulated, the figure travelled far beyond the place of its reported appearance. Hirado's Himeuo and related prophetic mermaids from Echigo have similar pictures and captions, showing how popular responses to epidemic disease could spread through the publishing and peddling networks of the late Edo period. Attempts have been made to identify Jinja-hime with a real marine animal, but no such identification is supported by conclusive evidence. In folklore, it is better understood beside Amabie and Amabiko: a creature that comes from the sea, predicts harvest and illness, and leaves human beings an image to use as a charm. Its importance lies less in zoological identity than in the meeting of prophecy, print culture, and the wish to survive an epidemic.

In this version, we read the Jinmenken as a "road urban legend" born from the city during the late Showa era. The Jinmenken is not a yokai that appears fully formed in classical texts; rather, it is an entity where the rumor ran ahead, and magazines and television later gave it a contour. Because of this, its details are never fixed. Where it was seen, what it said, and whose face it resembled shift depending on the teller, and this malleability served as the fuel for its popularity. The stage of the "road" underpins the eeriness of the Jinmenken. On a night road, animal carcasses, lost dogs, the optical illusions of headlights, and suddenly crossing shadows are everyday occurrences. When an easily recognizable component like a "human face" is mixed in, the witness feels that "perhaps it wasn't a dog." The speed of vehicular society robs people of the time to verify. Passing by without being able to confirm whether it was a misperception or an anomaly strengthens the rumor. The Jinmenken's dialogue elevates this anomaly from a mere composite animal to an urban legend. Words like "Leave me alone" or "What are you looking at?" are closer to rejection than horror. The monster is not attacking; it hates your gaze. This sensation closely resembles the awkwardness of witnessing someone's bizarre behavior on a city street. The one who sees the yokai is slightly blamed as the rude interloper. In the realm of modern folktales handled by Miyoko Matsutani, modern vehicles and urban infrastructure become the sources of new ghost stories. The Jinmenken is positioned perfectly within this current. Instead of emerging from the old natural environment like fox-fire or a mountain witch, it appears from late-night stores, national highways, housing complexes, and the roads home from school. This dog clearly demonstrates how the stage of yokai has shifted in accordance with changes in lifestyle. This version of the Jinmenken is a yokai of incomplete transformation. The dog did not turn into a person; it remains a dog but merely possesses a human face. That incompleteness becomes both a joke and a nightmare. Children found it amusing as a rumor, and adults consumed it as a media phenomenon, but at the bottom of it all lies the lingering anxiety that "somewhere in the city, you might encounter something that cannot be classified." The Jinmenken is the form of that anxiety running at its lightest and fastest. Through the media, this version of the Jinmenken became a monster that "everyone knows, even though no one has seen it." Most people have never actually encountered it. Even so, anyone can instantly imagine the scene of a dog with a human face speaking. The rumor distributes the image before the sighting, and that image in turn generates new eyewitness accounts. The choice of a "dog" is also sharp. A dog is close to the human sphere of living, considered a loyal and familiar animal. When a human face is pasted onto it, that familiarity is shattered instantly. If it were a complete monster, you could keep your distance; but because it is a dog, you momentarily approach it. That delay establishes the ghost story of the Jinmenken. The Jinmenken also carries the burden of urban loneliness. Even though it can speak human language, it doesn't seek conversation; instead, it rejects it with "Leave me alone." This is remarkably similar to the sensation of city life, where people are densely packed yet do not interact with one another. The anomaly doesn't attack humans, but finds the very gaze of humans to be a nuisance. Within that lies its coldness as a modern yokai.

Even among early modern ghost fire tales, the Jiosenbi is a rare example where "who, where, and why" are told in concrete detail. The victim is not a nameless monster, but a peddler selling a real-life sweet called Jiosen, and the scene is the Hizagashira Pine at Izuminawate near the Tokaido's Minakuchi post town—a large tree whose location people could identify. The conditions for the fire's occurrence are also restricted to "rainy nights." It is thought that the experience of seeing will-o'-the-wisps or fox fires on humid nights became intertwined with memories of murders along the highway, solidifying into a single ghost story. The fire as a symbol of obsession with money connects to the lineage of grudge tales born from the monetary economy of early modern cities. As an apparition rooted in the land of Minakuchi, Koka District, it holds value in being passed down alongside other local entities like the Katawa-guruma and Koka Saburo.

The jorōgumo is a composite yokai shaped by the name of a living spider species, early modern ghost stories of shapeshifting women, Toriyama Sekien’s depiction of a woman's body overlaid with spider legs, and regional legends of spider-haunted pools. In Tonoigusa, a visiting mother and child dissolve into a monstrous attic spider, while in Taihei Hyaku Monogatari, a maiden pleading for marriage proves to be an illusion cast by a tiny spider beneath the eaves. In waterside lore, it casts fine silk onto a person's foot—threads capable of dragging a huge log into the depths once transferred. The popular modern image of a lute-playing seductress who devours men does not appear in any single verified classical text.

Juroujin's true form is the South Pole Old Man Star (Canopus). This is the alpha star of the constellation Carina—the second brightest star in the entire night sky after Sirius. Because it only appears low in the southern sky of the Northern Hemisphere, ancient Chinese lore passed down the saying, "The year it can be seen is a year of universal peace; the land where it can be seen is a land of longevity." Already registered as an astronomical deity in the 'Treatise on Astrology' of the *Records of the Grand Historian* and the 'Treatise on Astronomy' of the *Book of Jin*, it forms the core of Longevity Star worship in Chinese folk belief. Daoism personified this star as the Longevity Star or Longevity Sage, arranging auspicious items alongside him: a black stag said to live 1,500 years, the Peaches of Immortality of the Queen Mother of the West (which extend life by a thousand years with a single bite), and a gourd containing the elixir of immortality. Iconographically, he is depicted as a short old man with a long head and a long beard, tying a sutra scroll to the head of his staff. A "short body and long head" is a physical omen of longevity in Chinese physiognomy, a formative principle entirely identical to that of his counterpart, Fukurokuju. This is the reason the two have long been considered the same deity under different names. His arrival in Japan occurred in the late Muromachi period (15th century), routed through monks traveling to Song and Ming China and the importation of Daoist and Buddhist paintings by Zen monasteries. The prototype of the current Seven Lucky Gods was formed during the Higashiyama culture period when Zen monks and painters (such as Noami, Soami, and Sesshu) bundled the localized Ebisu, Daikokuten, Bishamonten, and Benzaiten with the imported deities Hotei, Fukurokuju, and Juroujin into the "Seven Gods of Fortune and Virtue." The overlap with Fukurokuju had been an old issue since before the Song dynasty. In Japan, this was resolved by dividing their roles: "Fukurokuju = a secular deity synthesizing happiness, wealth, and longevity," and "Juroujin = an ascetic longevity deity purified to the single virtue of longevity." During the Edo period, a significant number of variant Seven Lucky Gods groupings circulated that removed Juroujin to avoid duplication, replacing him with the sake-loving beast Shojo, Kisshoten, or Fukusuke. Juroujin was loved by the common people for his appearance as an unpretentious, sake-loving sage, appearing frequently in the treasure ship pictures of Kyoden Santo (*Kottoshu*, 1813), Hokusai Katsushika, Kuniyoshi Utagawa, and Yoshitoshi Tsukioka. In the Seven Lucky Gods pilgrimages across Edo and Tokyo, his sites were often small halls belonging to Zen, Obaku, and Tendai sects, gathering prayers for longevity and health, especially from the elderly and the sick. In folk tradition, he also holds an important position as a main constituent deity of the "First Dream Treasure Ship" (established in the mid-Edo period), where placing a treasure ship picture containing Juroujin under one's pillow early on New Year's Day is said to grant an auspicious dream.

This version of Kagutsuchi bears fire not as a "convenient attribute" but as an "event that changes the world." In the "Kojiki," the scene where Izanami dies giving birth to the fire god instantly pivots the bright story of national creation to the tale of Yomi (the underworld). Fire is the result of birth, yet it takes the mother goddess away. Here lies the fundamental duality between the fire that sustains life and the fire that burns houses and bodies. The scene of Kagutsuchi being slain is the epitome of creation arising from destruction. When Izanagi's sword severs the fire god, other deities are born from the blood and body parts. The myth does not end by extinguishing the fire. Even when cut, the power of fire branches off into blood, swords, mountains, and lightning. Kagutsuchi is not a self-contained deity, but a generating device for subsequent gods. Layering the variant traditions of the "Nihon Shoki" reveals that Kagutsuchi is the totality of fire passed down with fluctuating names and personalities in the Kiki. Names like Kagutsuchi and Homusubi are not mere spelling differences, but indicate multiple perspectives grasping fire as "that which burns," "that which creates," and "that which possesses spiritual power." In YOKAI.JP, explaining this fluctuation adds depth to the page as a divine spirit. Kagutsuchi, expanding into fire prevention beliefs, reverses from a god of terror to a god of protection. At Atago Shrine and Akihasan Hongu Akiha Shrine, prayers are continuously offered to him as a god of fire and fire prevention. Precisely because he is the god with the power to cause fires, he is expected to have the power to quell them. The mindset of not avoiding the cause of disaster but praying at its center is characteristic of Japanese fire protection beliefs. Visually, this version is better suited by layering childbirth, swords, and mountains rather than a simple ball of flame. Red fire, black soot, blood dripping from a sword, fire protection talismans on mountain peaks, the dark entrance to Yomi. When these elements align, Kagutsuchi stands up not as a fantasy fire attribute, but as a dangerous turning point in myth. In diagnoses or cards, Kagutsuchi symbolizes strong change. When one cannot proceed to the next stage without ending something, when one has no choice but to burn down the old order, he becomes a terrifying but necessary god. However, fire cannot be treated lightly. Kagutsuchi's protection is only directed at those who take responsibility even for the aftermath of the burning. Reading Kagutsuchi in relation to Izanami, fire appears as a wound left on the mother goddess's body. The birth of fire takes the mother, and her death spawns the story of the underworld. In other words, Kagutsuchi bears not only the blessing of parent-child relations but also the mythological pain that birth hurts someone. There is a weight there beyond a mere god of flames. Kagutsuchi as a god of fire prevention is also the name for humans to coexist with dangerous forces. Life cannot be sustained without using fire. But if fire is used, disaster can strike at any time. Prayer is not a technique to extinguish fire, but the ethics of living with fire. If this sense of daily life is included in Kagutsuchi's page, ancient mythology and folklore connect beautifully. In the association network, it expands not only to Izanami and Izanagi but also to fire and mountain anomalies like Atagoyama Tarobo and Kasha. Placing Kagutsuchi allows the stream from the upper reaches of mythology through folk fire protection beliefs to yokai-like images of fire to converge into a single flow.

Early modern Japanese accounts of Kaijin drew on two streams of information: reports imported from overseas and descriptions in domestic natural histories. The traditions eventually overlapped. Kaijin is broadly human in shape, but webbing between the digits and loose skin over the entire body set it apart. The skin gathers in folds at the waist and looks almost like a wide pair of hakama. Whether it understands language is uncertain. Most sources say it neither comprehends human speech nor answers, although a variant claims that one survived on land for an extended period. Its diet is equally unclear because many accounts emphasize its refusal of food offered by people. When a captured Kaijin is kept away from the water, it weakens quickly and may die within days. Some have suggested that observers mistook a sea lion or seal for a human figure. Another explanation treats the apparent clothing or folds as seaweed clinging to the body. Neither has been proven. Part of the tradition came through Nagasaki in reports carried by ship, and part came from sightings along the Japanese coast; names and dates differ from source to source, so the material cannot be reduced to one clearly defined animal. Kaijin is best understood as a representative early modern account of an uncanny creature captured at the edge of the sea.

Kainan Hōshi is inseparable from the taboos observed in the Izu Islands on the twenty-fourth day of the first lunar month. It is described as the vengeful dead of maritime disasters. Some origin stories point to a hated island official; others tell of a group of young people killed together in a storm. The resentful spirits cross from offshore in washbasins or small boats, and anyone who sees them may suffer calamity. That night, households cover their entrances with baskets, place branches of holly and tobira—Japanese cheesewood—in the storm shutters, close themselves indoors, and avoid even outdoor trips to the privy. The next day, the tobira is burned and the crop forecast from its cracking sounds and the way the branches swell. Customs differ considerably from island to island. At Senzu on Izu Ōshima, the visitor is called Hiimi-sama and remains the object of shrine rites; one account assigns a particular family to wait beside the shore through the night. On Kōzushima, shrine priests preserve a solemn nocturnal reception that gives the vengeful spirit the character of a visiting deity. On Miyakejima, plates and earthenware are placed at doorways and small children are put to bed early. Over time, these practices became a shared rule for guarding the boundary between sea and community. Stories warn that anyone who mocks Kainan Hōshi or breaks the taboo may encounter strange events or fall ill. Researchers have also noted that related traditions are scarce in the southern islands, so the distribution is uneven. Kainan Hōshi is not a general name for every maritime ghost. It belongs to the calendar, ritual life, and one recurring night of the Izu Islands.

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.

An interpretation based on Toriyama Sekien’s Hyakki Tsurezurebukuro image and inscription. The water jar faces forward, its rim becomes the mouth, and patterns on the body are read as eyes and nose. The inscription pivots on the phrase “calamity turns to good fortune,” entrusting the vessel with the idea that blessings fill after adversity. Placed at the end of the volume to serve a congratulatory cadence, its nature is read as leaning more toward good than ill. Though grouped with tsukumogami familiar to early modern life, independent oral lore or怪談 are scarce. Later retellings expand the “inexhaustible when drawn” motif into control over water’s increase, decrease, and measured pouring, but the original is a symbolic painting with verse, and narrative deeds are limited.

Rooted in the Treasure Compendium account and given concrete form in the Otogizōshi Tamura tales, this type portrays the yokai as a shape-shifting brigand haunting the strategic pass at Narazaka, preying on travelers and tribute. The monk guise, gigantic body, and golden sling-stones became fixed traits. The golden stones are ranked as Tarō, Jirō, and Saburō, each escalating in power and boasted to shatter mountains and armor. The usual slayer is Inase Gorō Sakanoue no Toshimune, who leads troops, blunts the stones with traps and quick wits, and relentlessly pursues the creature with secret whistling arrows. The tale ends in surrender and execution, restoring safety to a key route. It is understood as a specter embodying the dangers and brigandage of local slopes and passes, emphasizing metallic gleam and the terror of flying stones.

Reconstructed after the iconography seen in the Matsui Library Hyakki Yagyō handscroll and other monster scrolls held by institutions such as the National Museum of Japanese History: a bird-faced figure brandishing a raised hammer. Following the sources, its name is noted as Kanezuchibō, with a comment on its affinity to the cognate form Daichiuchi; its deeds and origins remain unknown. While the hammer suggests a tool-turned-tsukumogami reading, no explicit statement in the sources confirms this. It is most often depicted as a member of a procession, one of the recurring motifs in Hyakki Yagyō imagery. Later metaphorical readings (e.g., caution or self-effacement) are treated as secondary interpretations and not conflated with the original tradition.

Ultimate Metamorphosis and Empathy. The greatest characteristic of Kannon Bodhisattva lies in having no fixed form, possessing the ability of "Fumon Jigen" to infinitely transform into the most suitable form (a Buddha, a god, a human, or even a non-human entity) to save the other person. This is not mere magic; it is the manifestation of an "ultimate empathic ability (compassion)," standing at the exact same eye level as the suffering other and sharing their pain as one's own. Kannon has served as the emotional pillar for the Japanese people for over a millennium precisely because Kannon does not reign as an absolute, transcendent dictator, but descends into the mud-stained living spaces of humans to weep alongside them. Attendant to Amida Nyorai and Care at the Moment of Death. Kannon Bodhisattva is not only worshipped independently but also plays a crucial role as an attendant (assistant) to Amida Nyorai, the Lord of the Western Paradise (Pure Land). When a person reaches the end of their life, it is Kannon's duty to appear riding on a cloud alongside Amida Nyorai (Raigo) to welcome the deceased, placing their soul on a lotus pedestal to guide them to paradise. Kannon was not only a savior from all the hardships of the present world but also the "ultimate deity of terminal care" who alleviated the fear of death and guaranteed the soul's destination. The "Hidden Christians" and Maria Kannon. The vast tolerance of Kannon worship (the flexibility to take any form) proved its worth even in the harshest phases of history. Under the ban on Christianity during the Edo period, oppressed "Kakure Kirishitan" (Hidden Christians) secretly continued their worship by venerating statues of the "Jibo Kannon" (Koyasu Kannon, holding a child) as the Virgin Mary. By embracing even the god of a foreign religion as a variation of its own form and receiving the prayers of persecuted people, the "Maria Kannon" demonstrates the absolute zenith of Kannon worship's function as an asylum (sanctuary).

The kappa is Japan’s archetypal water yokai, a river dweller that carries water in a dish on its head. The Edo-period Wakan Sansai Zue describes it as a sumo-loving creature the size of a ten-year-old child that drags cattle and horses into the water, while the Butsurui Shōko records local names such as kappa in the east, kawatarō in the west, and enkō in Shikoku. It drowns people yet, once caught, swears pledges of apology and teaches bone-setting remedies, a double nature often explained as that of a fallen water deity. From Kyushu to Tōhoku, its traditions range from kappa who become mountain yamawaro in autumn to the tale of Katō Kiyomasa and Kusenbō.

This is an interpretation of the one-eyed, one-legged paper umbrella monster, typified by post-Edo period kusazoushi (illustrated entertainment books) and performing arts. In this version, Karakasa-kozou is not a terrifying vengeful spirit that takes human lives, but exhibits an extremely comical and mischievous nature, lurking in the dark to surprise passersby and enjoying their reactions. Although its iconographic roots trace back to the Muromachi period's *Hyakki Yagyo Emaki*, the widely recognized form of "the umbrella handle becoming one leg, with a single eye and long tongue sticking out from the umbrella's fabric" is the result of repetitive production in late Edo "monster playing cards," sideshows, and kabuki trick props. Lined up with visually impactful yokai like the Rokurokubi and Mitsume-kozou, it became a staple star of "toy prints" for children due to the amusement of its design. It appears in alleyways and under eaves at night, hopping on one leg while rustling its frame, causing visual and onomatopoeic strange phenomena, such as licking human faces with its long tongue, but it causes no essential harm. Because it lacks region-specific legends, its haunts and activities are freely adapted depending on the medium, which ironically made it easy to adapt to modern movies and animation. In a sense, it is the ultimate form of Edo townspeople culture completely deodorizing the primal fear of "tsukumogami"—the idea that old objects possess souls—into a "character (toy)" and sublimating it into entertainment.

Kariba Myojin is the guardian deity of Mount Koya who most purely embodies the nature of a "God of Guidance." The religious logic that sacred sites are not found by humans but revealed by gods was narrativized into the legend of a hunter and divine dogs guiding an esoteric Buddhist practitioner into the mountains. His true name, Takanomiko no Okami, means the child deity of Niutsuhime. By both mother and son deities yielding the divine territory to Kukai, it represents the local pantheon's approval of the site becoming a sacred ground for Shingon esoteric Buddhism. The iconography of the kariginu, bow and arrows, and two dogs preserves the form of an ancient mountain god presiding over mountain livelihoods (hunting) and resonates with the historical fact that the Niu clan was a group of hunters accompanied by sacrificial dogs. The divine dogs generated a belief as "guiding divine dogs" leading people to good matches and happiness, a motif carried on by the modern Kishu dogs, Shiromaru and Kuromaru, at Niutsuhime Shrine. The footprints of this guiding deity are carved throughout the pilgrimage routes, such as the Mount Koya Choishi-michi and Niukanshofu Shrine.

A composite form of the bakeneko that solidified in the late 17th century. An aged cat arrives with thunderstorm or dark clouds, seizing the corpse from a coffin by exploiting lapses during funeral processions or wakes. After Toriyama Sekien’s illustrations, the feline form became standard. Regional lore varies: forked tails, attendant will-o’-wisps, or concealment within black clouds. Its targets are not limited to evildoers. Folk countermeasures include night-long vigil at the wake, placing knives or razors atop the coffin, using prayer beads and sutra recitation, and disruptive funeral tactics.
