Hachiman

← Encyclopedia

On the Kunisaki Peninsula in the northeast of Kyushu, where wooded ridges fall toward the inland sea, a shrine stands above a curving vermilion bridge and a pond of lotus. Three halls in a row, each a paired roof of cypress bark joined front to back, hold three altars. The central altar belongs to a kami who is also an emperor of the deep past; the altar to one side, to his mother, an empress of the conquest-legends; the third, to a goddess whose name the tradition has long debated. This is Usa Jingū, the head of some forty thousand shrines, and the kami enshrined there is Hachiman — the great kami of the eight banners, the guardian of the realm and its war-god, and the figure in whom the kami and the buddhas drew nearer to each other than anywhere else in the islands.

A deified emperor and the name of eight banners

The name Hachiman is written with the characters for “eight” and “banner,” and in older reading it was sounded Yawata — the kami of the eight banners. The tradition explains the banners as the eight heavenly streamers that descended at the birth of a divine child, and that child it names as Homuda-wake, who would reign as the fifteenth sovereign, the Emperor Ōjin. Hachiman, in the shrine tradition, is the deified spirit of that emperor; the kami and the ruler are one. Ōjin’s traditional reign is placed in the late third and early fourth centuries — the chronology of the Nihon Shoki gives roughly 270 to 310 — but those dates belong to the semi-legendary stratum of the early imperial line, and the historicity of the reign is not something the documentary record can confirm. What the record does show is a kami of Usa drawn, over time, into the person of a remembered emperor.

At Usa the kami is rarely worshipped alone. He stands in a triad, the Hachiman Mikami, beside two female figures: a himegami, a goddess whose identity the tradition itself leaves uncertain, and the spirit of Empress Jingū, mother of Ōjin and heroine of the conquest-legends, who in the Kojiki and Nihon Shoki is said to have led an expedition against the Korean kingdoms while carrying the future emperor in her womb. A deified ruler, then, stands behind the war-kami’s name, and behind the ruler a warrior-mother. The earliest written notice of Hachiman comes from the Nara period; the shrine at Usa was raised in the early eighth century, and a tradition counts the kami’s first manifestation there far earlier, in the sixth.

The shape of the evidence matters here. The written sources for the early kami — the Kojiki of 712, the Nihon Shoki of 720, and the gazetteers and liturgies that followed — were compiled at the imperial court, and the Nihon Shoki in particular was assembled to set out and to legitimize the descent of the ruling line. The genealogy that makes Hachiman the spirit of Emperor Ōjin is not a neutral chronicle but part of that larger work of legitimation. Like all the deities of the imperial mytho-histories, Hachiman reaches the page already braided into the lineage of the throne — and that braid was drawn deliberately, for the Yamato court that compiled the chronicles told the story of the kami to anchor its own claim to rule. The local cult at Usa is older and more diffuse than the imperial reading laid over it; whether the kami of the eight banners was always understood as the deified Ōjin, or whether the identification was made as the court drew the southern shrine into the orbit of the dynasty, lies beyond what the sources will settle.

From regional kami to guardian of the nation

What distinguishes Hachiman among the kami is the breadth of his ascent. He begins as a deity of one district in Kyushu and rises to the tutelary of the whole nation, called upon by the throne at the great hinges of its history.

The first of those moments came in the middle of the eighth century, when the court of Nara cast the colossal bronze Buddha — the Daibutsu — for the temple of Tōdai-ji. The project strained the realm, and in 749 the kami of Usa was reported to have offered, through an oracle carried north to the capital, his support for the casting. A portable shrine bore Hachiman’s spirit to Nara to stand guard over the great work. The episode is decisive: at the very founding of the largest Buddhist monument in the land, a kami was enlisted as its protector, and the two religions were joined in a single undertaking. Two decades later, in 769, an oracle delivered in Hachiman’s name at Usa was invoked in one of the gravest crises of the early court — the affair of the monk Dōkyō, whose ambitions toward the throne were checked when an envoy, Wake no Kiyomaro, returned from the shrine with a pronouncement that the imperial succession must remain with the imperial house. Whatever the politics behind it, the incident shows the kami of Usa already functioning as an oracle of the realm, a voice consulted on the destiny of the dynasty itself.

In 859 a branch of the cult was established at Iwashimizu, on a hill of Otokoyama south of the new capital at Heian-kyō, the city now called Kyoto. Iwashimizu Hachimangū became, in effect, the guardian shrine of the capital, ranked among the highest in the land and tended in close relation to the court. The kami of a southern island had become a kami of the center.

His sternest service came in the thirteenth century, against the fleets of the Mongol Khan. When the armies of Kublai Khan crossed to Kyushu in 1274, and again in 1281 with a far larger force, the realm appealed to its kami and buddhas for deliverance, and Hachiman the war-god was foremost among those called. Both invasions were broken, in large part, by great storms that wrecked the invading ships in the waters off the coast. The storms were understood as kamikaze, divine winds, sent in answer to the prayers of the realm — and in the tradition the war-kami stood behind them. The deliverance fixed Hachiman in the national memory as the protector who turns back the foreign sword.

The kami of the bow and the horse

Hachiman’s deepest mark on Japanese life was made through the warrior. In the eleventh century the Minamoto, the great military house that would come to rule, claimed descent from Emperor Ōjin and took Hachiman as their clan-kami, their ujigami. Minamoto no Yoriyoshi vowed himself to the kami at Iwashimizu before his campaigns and credited his victories to him; his son Yoshiie was carried as an infant to the same shrine and there received his coming-of-age name, Hachiman Tarō — “Hachiman’s eldest son” — becoming the very image of the ideal warrior. When Minamoto no Yoritomo founded the warrior government at Kamakura at the end of the twelfth century, he raised the kami’s shrine at the heart of his new city: Tsurugaoka Hachimangū, transferred from an earlier site in 1180 to stand on its hill above the broad approach-avenue, the spiritual center of the first shogunate and the guardian of the warrior class the shogun had brought to power.

With the warriors the cult spread. As the samurai rose to govern the country through the long medieval centuries, Hachiman’s shrines multiplied across the provinces; a branch was raised wherever a warrior house wished to set the clan-kami of the Minamoto over its own holdings, and his name became the warrior’s invocation — Namu Hachiman Daibosatsu, “Hail to the Great Bodhisattva Hachiman,” cried before battle. He was the patron of kyūba no michi, the way of the bow and the horse, the twin arts at the core of the early samurai’s calling: the mounted archery still performed as yabusame at his shrines is offered to him. The kami’s banners were borne into the field, and the great gates of his shrines marked the towns the warriors built. Yet the war-kami was never merely a god of slaughter. He was honored at the same time as a kami of mercy and of the protection of the common people — a guardian, in the tradition’s understanding, rather than a devourer; the deity to whom one prayed not only for victory but for the safety of the realm and the well-being of those within it. The doubling is intrinsic to him: the bow and the open hand held together.

Hachiman Daibosatsu, and the rupture of 1868

Of all the kami, Hachiman is the one in whom the fusion of the native cult with Buddhism went furthest. The joining of the two religions — shinbutsu-shūgō — runs through the whole medieval history of the islands, and Usa is remembered as one of its cradles: the temple of Miroku-ji was built within the shrine precincts in the late eighth century, a jingū-ji or “shrine-temple” sometimes called the first of its kind, where Buddhist clergy chanted sutras for the kami. Out of this nearness grew the doctrine of honji-suijaku, by which the kami were understood as local traces, the suijaku, of buddhas and bodhisattvas whose true and original ground, the honji, lay in the Buddhist cosmos. Hachiman’s original ground was most often identified with Amida, the Buddha of the Western Pure Land — the figure at the heart of Pure Land devotion — though other schools assigned him otherwise.

What set Hachiman apart was the title the union gave him. In the eighth century he was honored as Daibosatsu, “Great Bodhisattva” — a buddha-being on the path to enlightenment, who out of compassion remains in the world to aid all sentient beings, here in kami form. He is reckoned the first of the kami to receive such a title, and for roughly a thousand years he was worshipped as Hachiman Daibosatsu, neither simply kami nor simply buddha but the two at once: a guardian of the realm who was also a figure of Buddhist mercy, his martial office and his bodhisattva’s compassion folded into a single name. The fusion took visible form. In 1201 the sculptor Kaikei, one of the masters of the age, carved for Tōdai-ji the image known as Sōgyō Hachiman — the war-kami seated in the robes of a Buddhist priest, head shaven, hands at rest, a monk and a god in one body. There is no plainer image in the land of how completely the kami and the buddhas had grown together. To stand a warrior-deity in a monk’s habit, and to call him both kami and bodhisattva without contradiction, was the ordinary religious sense of medieval Japan, not an eccentricity of it.

That union was broken by the state in the nineteenth century. With the Meiji Restoration of 1868 the new government decreed the formal separation of kami and buddhas, the shinbutsu bunri, ordering the two cults disentangled at every shrine; the policy loosed, in places, a wave of anti-Buddhist destruction, the haibutsu kishaku, in which temple buildings and images were torn down. At the shrines of Hachiman the Buddhist halls were removed, the sutra-chanting clergy expelled, and the title Daibosatsu set aside: Hachiman was reclassified as a kami pure and simple. The “pure Shinto” that resulted was, in good part, a modern construction read back over a syncretic reality a millennium deep. The separation should not be mistaken for a recovery of an original purity; it was a rupture, the unmaking of a fusion that for most of recorded Japanese history had been the normal shape of the kami’s worship.

The afterlife of the war-kami

Hachiman remains one of the most widely honored of the kami. His shrines number in the tens of thousands — by common count around forty thousand, second only to those of Inari — and they fall into two great families: the branches of Usa, the ancient head shrine in Kyushu, and the branches of Iwashimizu near Kyoto, of which Tsurugaoka at Kamakura is the most famous. The main hall at Usa, in the distinctive Hachiman-zukuri style of paired roofs, is a National Treasure, and the Kaikei statue at Tōdai-ji is counted among the nation’s treasures as well.

The festivals continue. At Tsurugaoka and elsewhere the autumn rites include yabusame, the mounted archers in court hunting-dress loosing their blunt arrows at wooden targets along a straight course at full gallop — the old way of the bow and horse offered to the kami who patronized it, a ritual that traces its descent at Kamakura to the founding of the shrine under the first shogunate. Hachiman’s emblem, the white dove, descends from the messenger-bird of his legend; at Tsurugaoka the stroke of the character for “eight” on the great nameboard is drawn as a facing pair of doves, so that the kami’s number and his bird are one mark.

The breadth of the cult outlived the warrior age that carried it. With the end of samurai rule in the nineteenth century and the disestablishment of the Daibosatsu title, Hachiman might have receded, as a war-god of a vanished class; instead he remained among the most thickly shrined and widely visited of the kami, drawn on still for protection, for safe childbirth — the kami was, after all, an emperor born of a warrior-empress — and for the ordinary petitions brought to any great shrine. The two faces he had always shown, the bow and the open hand, let him pass from the religion of the warrior into the religion of the people without losing his name.

The war-kami’s history is double, like the kami himself. He carries the memory of the warrior houses and their wars, and the memory of the divine winds that broke the Khan’s fleets; he carries, too, the memory of a thousand years in which a Japanese kami was a Buddhist bodhisattva, the plainest case the islands ever produced of two religions made one. The old title Daibosatsu, struck from the registers in 1868, still clings to the war-cry remembered in the chronicles and the temple records — a small surviving mark of how near, for most of their shared history, the kami and the buddhas once stood.
