Bronze Seated Statue of Yakushi Nyorai

A Medicine Buddha Bought Back from the Scrap Heap

In the winter of 1868, a small gilt-bronze figure of the Medicine Buddha was carried out of the inner sanctuary of Katori Jingu, one of eastern Japan's oldest shrines, and put up for sale among the townspeople. A new government had just ordered shrines and temples to be pulled apart, and metal images like this one were worth more melted down than kept. The following year a benefactor from nearby Sawara bought it back, fitted it with a new pedestal, and gave it to a hilltop temple called Kanpuku-ji, where it has stayed ever since.

That figure is the Bronze Seated Yakushi Nyorai, one of four cast Buddhist images at Kanpuku-ji in Katori City, Chiba Prefecture. It stands only about 33 centimeters tall, yet it carries the weight of two very different worlds: the medieval shrine where Shinto deities and Buddhas were worshipped as one, and the moment, six centuries later, when that union was violently undone.

When a Kami Was Also a Buddha

For most of its history Katori Jingu was not a purely Shinto site. From the Nara period onward, the shrine kept Buddhist halls, sutra repositories, and images on its grounds, following the idea that Japan's deities and the Buddhas were two faces of the same sacred power. Under this thinking, known as honji-suijaku, each kami had an "original ground" form as a particular Buddha or bodhisattva. Inside the main sanctuary, set before the seat of the deity, the shrine kept four of these original-ground images, called honji-butsu.

The four were not freestanding statues. Each is a kakebotoke, a seated figure cast in bronze and originally mounted against a large circular metal disc that served both as a halo and as a mirror, recalling the polished bronze mirror long treated as a sacred object in Shinto. Plaques of this kind were offered to shrines and temples across Japan from the late Heian period into the Muromachi period. The Kanpuku-ji set is widely regarded as among the finest surviving examples from the Kamakura period.

Two of the four carry dated inscriptions. The Shaka Nyorai and the Eleven-headed Kannon were cast in 1282 by a craftsman recorded as Rengan, and their inscriptions ask for the peace of the realm, the prosperity of the shrine, the fulfillment of vows, and the "subjugation of foreign lands." That last phrase points to the Mongol invasions: the second great assault had been turned back only the year before, in 1281, and the casting reads almost as a thanksgiving. A third image, the Jizo Bosatsu, was added in 1309 by a senior shrine priest, Onakatomi no Sanetane, in memory of his late father.

The Quiet Puzzle of the Yakushi

The Medicine Buddha is the odd one out. Its original mirror disc, which would have carried the inscription giving its date and purpose, is missing, so the year it was cast cannot be fixed with certainty. Looked at closely, it does not quite match the 1282 pair. It lacks the small jewel set into the cranial bump and the tuft of hair between the brows that the Shaka and Kannon images both have, and the way it was fitted to its pedestal is built differently. Specialists therefore doubt that it belonged to the same original casting as those two, even though all four are now kept together as a single group.

The likeliest reading is that the Yakushi joined the set later, replacing one of the original four that had been lost. Whatever its exact origin, it remains a Kamakura-period work, and its survival at all is remarkable given how close the whole group came to the furnace.

Yakushi Nyorai, the Buddha of Healing, is usually shown holding a small medicine jar in the left hand, a sign of the relief from sickness that he vows to give. For pilgrims who once stood before the deity of Katori, this calm seated figure was the Buddha hidden inside the kami they had come to pray to.

Why It Is an Important Cultural Property

The four images were designated a National Treasure in 1913, under the older heritage law then in force, and were reclassified as an Important Cultural Property after the cultural-property system was rebuilt in 1950. They are registered not as sculpture but in the crafts category, because they are metalwork: cast bronze rather than carved wood, and made by techniques that belong to the bronze-caster's craft.

The casting itself repays attention. On these figures the head, body, and legs were cast together in a single piece using paired moulds, while the hands were cast separately and inserted. Two tenons projecting from the back once held the figure against its mirror disc, and four more beneath the knees fixed it to a pedestal. None of the original pedestals survive; the ones in place today were made later, including the new mount added when the images were rescued in 1869.

The craftsmanship matters, but so does the testimony these objects carry. The dated inscriptions tie them directly to a named shrine, a named priestly family, and a national emergency, the Mongol threat, that shaped thirteenth-century Japan. Few medieval bronzes can be located so precisely in time, place, and intention.

Visiting Kanpuku-ji and Around

Kanpuku-ji sits on a wooded rise at Makino in Katori City. Its formal name is Myoko-zan Kanpuku-ji, a temple of the Shingon Buzan school said to have been founded in 890. Together with Kawasaki Daishi and Nishiarai Daishi, it is counted as one of the three great temples of the Kanto region dedicated to Kobo Daishi as a guardian against misfortune, and at New Year it draws crowds seeking that protection.

The four bronze images are kept in a storehouse behind the main hall and are not on permanent open display, so viewing them generally needs to be arranged in advance with the temple. One of the four, the Eleven-headed Kannon, is at times lent out for exhibition elsewhere. It is worth confirming current arrangements before a special trip.

The temple grounds reward an unhurried visit in their own right. The approach is planted with weeping cherries that bloom in spring, the slopes turn green in summer and red in autumn, and among the graves is that of Ino Tadataka, the surveyor who produced the first accurate map of Japan; the temple holds his hair-and-nail grave. Kanpuku-ji lies an easy detour from Sawara, the canal-lined merchant quarter sometimes called "Little Edo," and from Katori Jingu itself, the shrine these images once served. The nearest rail access is Sawara Station on the JR Narita Line.
