Wakuya Manyo-no-Sato Tenpyo Roman-kan is a history museum in Wakuya Town, Miyagi Prefecture, dedicated to the fascinating story of Japan’s first recorded domestic gold production.
During the Nara period (710–794), gold discovered in Wakuya played an important role in completing the Great Buddha at Todai-ji Temple in Nara. Today, Tenpyo Roman-kan preserves and introduces this remarkable chapter of Japanese history through historical exhibits, archaeological materials, reconstructions, and hands-on activities.
The museum is located near the Koganeyama Gold-Mining Site, a nationally designated historic site, and Koganeyama Shrine. Visiting these sites together provides an excellent way to understand the history of gold in Wakuya while enjoying a relaxing day of sightseeing.
In 749, during the Tenpyo era of the Nara period, Kudara no Kyo Keifuku, the governor of Mutsu Province, presented approximately 900 ryo, or about 13 kilograms, of gold to the imperial court.
At the time, gold was not believed to be available in Japan in significant quantities, and the country depended on imported gold. The discovery in what is now Wakuya Town therefore represented a major turning point.
The gold was transported to Nara and used to provide the gilding for the enormous Great Buddha at Todai-ji. The discovery was considered so important that Mutsu Province was granted a three-year tax exemption.
The event became an important part of Japanese history, and Wakuya has continued to preserve this legacy through Koganeyama Shrine, the archaeological site, and Tenpyo Roman-kan.
Tenpyo Roman-kan is a history museum built around the Koganeyama Gold-Mining Site. The facility includes a historical exhibition area, an archaeological site plaza, and hands-on displays that help visitors understand how gold was produced in ancient Japan.
The exhibits introduce the history of gold production and the cultural background of the Nara period. Rather than simply viewing objects behind glass, visitors can also experience reconstructed techniques and learn how people in the past extracted gold from the natural environment.
The museum displays materials related to the discovery and production of gold during the Nara period. Visitors can also see a ceramic tile mural by the renowned Japanese painter Ikuo Hirayama, along with dioramas recreating scenes from the ancient period.
Ancient roof tiles and other artifacts discovered during archaeological excavations are also displayed. These exhibits make the museum particularly interesting for visitors fascinated by Japanese history and archaeology.
One of the most popular activities at Tenpyo Roman-kan is the gold-panning experience.
Participants use a traditional technique known as “wangake,” in which a shallow bowl is used with water to separate small pieces of gold from sand and gravel. The process is simple to learn but surprisingly absorbing, making it enjoyable for both children and adults.
Any gold discovered during the experience can be taken home as a souvenir, providing a unique and memorable reminder of your visit to Wakuya.
Next to the museum is the “Kugane-an” Golden Tea Room, where visitors can enjoy traditional Japanese matcha while looking out over a beautiful garden.
The tea room is designed around the imagery of gold and creates an atmosphere quite different from everyday life. Enjoying a bowl of matcha tea in a traditional Japanese setting is a relaxing way to take a break after exploring the museum and archaeological site.

Adjacent to Tenpyo Roman-kan is the Koganeyama Gold-Mining Site, the historic location associated with Japan’s first recorded gold production.
Archaeological excavations carried out in 1957 uncovered the remains of buildings from the Nara period, together with ancient roof tiles. These discoveries provided important evidence connecting the area with the gold production that supported the completion of the Great Buddha at Todai-ji.
In 1967, the site was designated a National Historic Site of Japan and has since been preserved and made accessible to the public.
Among the artifacts discovered here are decorated round roof tiles featuring a six-petaled lotus motif, flat roof tiles with flowing arabesque patterns, and a ceramic finial inscribed with the era name “Tenpyo.”
These artifacts have been designated Tangible Cultural Properties of Miyagi Prefecture. They provide valuable evidence of the technology, architecture, and culture of the Nara period.
Koganeyama Shrine stands within the area of the nationally designated Koganeyama Gold-Mining Site. The shrine is dedicated to Kanayamahiko-no-Kami, a deity traditionally associated with mines, metals, and metalworking.
A local tradition says that “if you visit for three consecutive years, you will never have to worry about money for the rest of your life.” Because of this belief and the site’s association with Japan’s first gold production, the shrine has become popular as a destination for prayers for financial good fortune and business prosperity.

One of the historic highlights within the shrine grounds is a monument featuring a poem from the Manyoshu, Japan’s oldest major anthology of poetry.
The poem celebrates the discovery of gold in the eastern region of Michinoku:
“May the reign of our sovereign flourish; in the eastern mountains of Michinoku, golden flowers are blooming.”
The poem beautifully expresses the excitement and significance of discovering gold in ancient Japan. For visitors interested in Japanese literature and history, the monument provides another fascinating connection with the distant past.
