Gilt-Bronze Epitaph of Ono no Emishi: A Window into Asuka-Period Japan

Hidden in the forested hills behind a quiet shrine in northern Kyoto lies the tomb of Ono no Emishi, a high-ranking official of the Asuka period (593–710) and the son of one of Japan's most celebrated historical figures—Ono no Imoko, the famous envoy sent to Sui Dynasty China. The gilt-bronze epitaph discovered in this tomb is designated a National Treasure of Japan and stands as one of the oldest and most important memorial inscriptions in the country.

This remarkable artifact, now carefully preserved at the Kyoto National Museum, offers a rare and intimate glimpse into the world of 7th-century Japanese court politics, family lineage, and funerary customs influenced by continental Asian traditions. For visitors with an interest in ancient history and archaeology, the epitaph of Ono no Emishi represents one of Kyoto's most fascinating and least-known cultural treasures.

What Is the Gilt-Bronze Epitaph of Ono no Emishi?

The gilt-bronze epitaph (金銅小野毛人墓誌, Kondō Ono no Emishi Boshi) is a rectangular bronze tablet measuring approximately 58.9 cm in length, 5.9 cm in width, and 0.4 cm in thickness. Its surface was engraved with Chinese characters and then gilded with gold, giving it the distinctive gilt-bronze appearance that lends the artifact its name.

The tablet bears inscriptions on both front and back, totaling 48 characters. The front side records the career and rank of Ono no Emishi, stating that he served in the court of Emperor Tenmu at the Asuka Kiyomihara Palace, holding the positions of Daijōkan (Grand Council of State member) and concurrent head of the Ministry of Justice (Gyōbu-taikyō), with the court rank of Daikin-jō—the seventh highest among the 26 ranks of the era. The reverse side identifies the tablet as marking the grave of Ono no Emishi and records his burial in the twelfth month of the year 677 (Tenpyō 6, year of the Ox).

This epitaph is recognized as the longest extant gilt-bronze memorial inscription from ancient Japan, making it an invaluable resource for understanding the political structure and burial customs of the late 7th century.

The Ono Clan: A Family of Diplomats and Statesmen

To fully appreciate the significance of this National Treasure, it helps to understand the illustrious family behind it. Ono no Emishi's father, Ono no Imoko, is one of the most famous figures in Japanese history. In 607, Imoko was dispatched as an envoy to the Sui Dynasty court in China by Prince Shōtoku—a diplomatic mission of profound importance that helped establish direct cultural and political ties between Japan and the Chinese mainland.

Ono no Emishi continued his family's tradition of public service, rising to prominent positions in the government of Emperor Tenmu. His son, Ono no Keno, also served in the imperial court under Empress Jitō. The area of Kamitakano in northern Kyoto, where the tomb is located, was historically the homeland of the Ono clan, and the gravesite is thought to be part of a broader Ono family burial ground in the hills of the Yamashiro region.

Why Was It Designated a National Treasure?

The gilt-bronze epitaph of Ono no Emishi was first designated as an Important Cultural Property in 1914 and subsequently elevated to National Treasure status on April 27, 1961. Several factors contributed to this prestigious designation.

First, the epitaph is one of the earliest surviving examples of a funerary inscription in Japan. The practice of burying memorial tablets with the deceased was adopted from Chinese customs that flourished during the Northern and Southern Dynasties through the Sui and Tang periods, and examples from 7th-century Japan are exceedingly rare.

Second, the inscription provides crucial historical evidence about the governmental structure of Emperor Tenmu's court. It confirms specific titles and ranks that supplement what is known from official histories such as the Nihon Shoki, offering firsthand archaeological corroboration of the political order of the era.

Third, the artifact's physical craftsmanship—cast bronze with incised characters and gold gilding—demonstrates the sophisticated metalworking techniques available in Nara-period Japan and reflects the high social status of the deceased. The tablet is believed to have been crafted and placed in the tomb posthumously, likely by Emishi's son Keno, some time after the burial in 677.

Discovery and Dramatic History

The story of how this epitaph came to light is itself a fascinating tale spanning more than four centuries. In 1613 (Keichō 18), during the early Edo period, local residents gathering firewood on the mountain behind Sudō Shrine in Kamitakano discovered an ancient tomb. Inside a stone burial chamber constructed of granite slabs, they found the gilt-bronze tablet.

After the discovery, scholars identified the tomb as belonging to Ono no Emishi based on the inscription, and the tablet was returned to the grave. However, in the Meiji period, the tomb was disturbed by grave robbers. Fortunately, the epitaph itself was not stolen. In 1913 (Taishō 2), during a formal archaeological survey of the tomb, the epitaph was permanently removed and entrusted to the Kyoto National Museum for safekeeping, where it remains to this day.

The tomb itself—a mounded burial featuring a stone chamber approximately 2.5 meters long, 1 meter wide, and 1 meter tall—was designated as a Kyoto City Historic Site in 1984. A stone marker inscribed by the renowned scholar Naitō Konan stands atop the burial mound, which can still be visited on the hillside behind Sudō Shrine.

Where to See the Epitaph: Kyoto National Museum

The gilt-bronze epitaph of Ono no Emishi is housed at the Kyoto National Museum (京都国立博物館), one of Japan's foremost repositories of cultural heritage. The museum periodically displays the epitaph as part of its rotating permanent collection in the Heisei Chishinkan Wing, particularly in the archaeology gallery.

Because museum displays rotate regularly to protect fragile artifacts, visitors interested in seeing the epitaph should check the museum's exhibition schedule before their visit. The museum's website and official social media accounts provide up-to-date information on which items are currently on display.

The Kyoto National Museum itself is a must-visit destination. Founded in 1897, it houses approximately 14,600 items spanning Japanese and East Asian art, including sculptures, paintings, calligraphy, ceramics, textiles, and archaeological artifacts. The striking Meiji-era redbrick building (currently closed for renovation) is itself designated an Important Cultural Property, and the modern Heisei Chishinkan Wing, designed by architect Taniguchi Yoshio, offers world-class exhibition spaces.

Visiting Sudō Shrine and the Tomb of Ono no Emishi

For those who wish to visit the actual burial site where the epitaph was discovered, Sudō Shrine (崇道神社) in the Kamitakano district of northern Kyoto provides a deeply atmospheric experience. The shrine is dedicated to Prince Sawara (posthumously titled Emperor Sudō), whose tragic death in the 8th century and subsequent veneration as a powerful spirit make the shrine one of Kyoto's most historically layered sites.

Within the shrine grounds is the subsidiary Ono Shrine, dedicated to the Ono clan including Ono no Imoko and Ono no Emishi. From behind the shrine, a mountain path leads approximately 140 meters uphill to the mounded tomb of Ono no Emishi. The walk through the dense forest is tranquil and evocative, offering a contemplative connection to the distant Asuka period. The tomb mound sits quietly among the trees, marked by the stone monument inscribed by Naitō Konan.

Sudō Shrine is free to visit and open at all times, making it an ideal stop for travelers exploring the quieter, less-touristed areas of northern Kyoto.
