⛩️ Kami Encyclopedia

A wind divinity anchored to Mount Tado, once feared as a one-eyed dragon god. Ideas of “divine wind” recorded in Edo-period sources intersected with local weather watching, leading sailors on the Ise Bay route and coastal villages to revere it deeply. Later it blended in folk belief with the smithing deity Ame-no-Mahitotsu-no-Kami, and shrines preserved doorless architecture so the god’s passage would not be hindered. It governs storms and rain, is invoked for bringing and stopping rain and for protection from maritime disasters, yet tales also stress its aramitama, a wild and fearsome aspect. Iconography varies: sometimes a dragon body, sometimes a one-eyed deity, but details remain uncertain.

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.

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.
