Copper Staff Head (with Double Dragon Ornaments / Discovered

A Bronze Object from a Sacred Summit

In July 1893, a civilian named Kawai Isotaro climbed Mt. Dainichi (2,501 m), one of the high peaks of the Tateyama range in what is now Toyama Prefecture. He was looking for hot springs, accompanied by a local guide, Doi Heisaku, and two others. What he found at the summit was not a thermal source but a small bronze object — corroded by centuries of wind and snow, yet unmistakably the head of a Buddhist priest's staff. The wooden box that came to hold it later bore his name and the circumstances of the discovery, written in ink.

That object, today designated an Important Cultural Property of Japan and known as the Bronze Shakujō Head with Twin Dragon Ornament (Dō shakujō-tō, sōryū-kazari), is among the most evocative survivors of early mountain worship in the Japan Alps. It stands about 17 centimetres tall, with a ring roughly 11 centimetres across. The shape is recognisable to anyone familiar with East Asian Buddhist iconography — the looping ring at the top of a shakujō, the metal-tipped staff carried by ascetic monks — but the workmanship here is unusual enough that scholars still discuss exactly when, and possibly by whom, it was made.

How It Was Discovered

The story of the find is preserved in inscriptions on the wooden case in which Kawai stored the staff head, and in records held by the Tateyama Museum. According to these, his small party climbed Dainichi to scout for thermal water. At the summit they came upon the bronze ring, apparently lying exposed or only lightly buried. Kawai brought it down and kept it; the object eventually entered scholarly attention and was studied alongside a separate, more famous staff head recovered from the summit of Mt. Tsurugi in 1907 by a survey team from the Imperial Japanese Army's Land Survey Department.

The Dainichi find predates the Tsurugi one by fourteen years, and its discovery is less widely known. Where the Tsurugi staff inspired a novel and a feature film (Tsurugidake: Ten no Ki), the Dainichi piece has been studied more quietly, mostly by specialists in Buddhist metalwork and in the history of Japan's mountain-ascetic tradition, known as shugendō. Only in 2021 did the family that had safeguarded the staff head for more than a century formally donate it to Toyama Prefecture, where it is now permanently held by the Tateyama Museum.

What Makes the Object Distinctive

A standard shakujō is meant to be hand-held and to rattle: loose rings hang from the upper loop, and a wooden shaft fits into the lower socket. In use, the staff signals a monk's presence, frightens wildlife on remote trails, and — in stricter doctrinal readings — marks a circle of religious authority around its bearer. The bronze ring on display at Tateyama is the metal head only; the original shaft is long gone, and several attachments are missing or eroded.

What survives is striking. The ring itself bulges gently, and at its centre the metal coils inward in a soft tendril that ends in two dragon heads facing in opposite directions, each crowned with a sacred jewel (hōju). At the very top of the loop sits a lotus pedestal supporting a vase form — a treasure vase, or hōbyō — that would have carried further ornament now lost. Two free-swinging rings, the yūkan, are preserved on either side. The casting is competent but not refined to the level of court-temple metalwork in Kyoto or Nara; the impression is of an offering made by, or for, a regional religious community deeply invested in this particular mountain.

Specialists generally date the piece to the Heian period (794–1185), though opinions on whether it belongs to the earlier or later part of that long era differ. The puffed, rounded silhouette of the ring resembles a well-known Nara-period shakujō kept at Hōryū-ji, which has prompted some scholars to favour a mid-Heian date at the latest. Others, including the director of the Tateyama Museum, see traits closer to late Heian style. The designation itself simply records "Heian period."

Why It Was Designated

The shakujō was given Important Cultural Property status on 1 July 1963. Three factors weighed most heavily in the decision.

The first is rarity. Fewer than a dozen Heian-period bronze shakujō heads are known to survive anywhere in Japan, and the twin-dragon variant at Tateyama is one of only a handful with this specific decorative scheme. The second is provenance. Buddhist liturgical objects of this age usually come from temple collections, where their history of ownership is documented but their original setting often obscured. The Dainichi staff head, by contrast, was recovered at the place where it had been deposited — the bare summit of a 2,500-metre peak. That alone gives it unusual evidential weight for the study of how mountain worship actually unfolded a thousand years ago.

The third is interpretive. Researchers now read the object as a kekkai offering: a ritual marker placed on the mountaintop to convert it from raw landscape into consecrated ground where ascetic practice could take place. A staff was a natural choice for this purpose. It calls the kami down from the heavens, draws a circle of protection, and lingers as a token of the practitioner's claim on the place. The Dainichi shakujō, together with a separate staff found on Mt. Tsurugi, anchors the archaeological argument that the Tateyama range was already a major centre of shugendō activity before the institutional Buddhism of the medieval period began documenting it.

Seeing It in Person

The bronze is on permanent display at the Tateyama Museum in Ashikuraji, a hamlet at the foot of the Tateyama range that once served as the southern gateway for pilgrims approaching the peaks. The museum complex spreads across roughly thirteen hectares and includes several separate buildings: the main Exhibition Hall, the Yōbōkan film hall, an art installation walk called Mandara Yūen, and several historic structures including the Nunobashi bridge associated with women's pilgrimage rites. The shakujō is shown in the Exhibition Hall alongside the better-known Tsurugi staff head and a small bronze standing figure of Taishakuten recovered from another Tateyama peak.

Photography of the shakujō itself is not permitted, in keeping with the museum's policy for designated cultural properties. Allow at least an hour for the Exhibition Hall, and longer if you plan to walk to the Nunobashi bridge or the Mandara Yūen, both within easy reach on foot.

Around the Museum

Ashikuraji itself rewards an unhurried visit. Just next door stands the Maetate Shadan of Oyama Jinja, the lower shrine of the three-part Oyama Shrine complex that crowns the Tateyama range; its main hall is also a designated Important Cultural Property. Across the road, the small Kyōsanbō building preserves a pilgrim's lodging from the Edo period, when Ashikuraji was a network of more than thirty such inns hosting climbers bound for the high peaks.

For those continuing into the mountains, Tateyama Station — terminus of the local rail line and starting point for the Tateyama–Kurobe Alpine Route — lies about ten minutes away by car. The Alpine Route opens fully from mid-April through November and offers some of the most spectacular high-mountain scenery in Japan, including the famous Yuki no Ōtani snow corridor in late spring. Mt. Dainichi itself, where the shakujō was found, is reached by experienced hikers from Murodō; the round-trip is a long day's walk and not suited to casual visitors.
