Oki Family Residence: A Distinguished Traditional House
The Oki Family Residence was the home of the family that served as chief priests of Tamawakasu-no-Mikoto Shrine. Built in 1801, it is regarded as one of the finest examples of a large traditional residence in the Oki region.
The house features an irregular hipped-and-gabled thatched roof and preserves distinctive elements of Oki-zukuri, a local architectural tradition found in the Oki Islands. Its substantial scale and carefully designed interior reflect the family’s important position within the religious community.
A Floor Plan Shaped by Shrine Life
The house faces east. Inside, the northern side consists primarily of an earthen-floored area, while the southern side contains the raised living spaces. The raised-floor section is arranged as six rooms in a three-by-two layout, creating a spacious interior characteristic of a substantial traditional residence.
Particularly interesting are the spaces specifically associated with the family’s religious duties. These include the Shinzen-no-ma, a room containing the household Shinto altar, and the Misogi-beya, a space used for ritual purification.
Such features are rarely found in ordinary private homes. They demonstrate how closely the daily life of the Oki family was connected with their responsibilities as Shinto priests and with the rituals of Tamawakasu-no-Mikoto Shrine.
Nationally Designated Cultural Heritage
The Oki Family Residence was designated as an Important Cultural Property of Japan in 1992 because of its historical and architectural significance. Protection extends not only to the building itself but also to the surrounding property.
The residence continues to be associated with the shrine and is carefully preserved as an important part of the historic environment. Its survival provides a valuable opportunity to see how a hereditary shrine-priest family lived and worked during the late Edo period.
Oki Family Treasure Hall: Rare Artifacts from Ancient Oki
Next to the residence, the Oki Family Treasure Hall displays valuable historical objects that have been preserved by the Oki family over generations. These artifacts provide important evidence for understanding the history of Oki’s administration, transportation systems, and religious culture.
The Eki-rei: A Unique Relic of Ancient Transportation
Among the most remarkable objects associated with the collection is an eki-rei, or station bell, said to be the only surviving example in Japan.
During the ancient Ritsuryo period, Japan operated a network of official stations along major routes. Eki-rei were used in connection with this system when official travelers needed to obtain horses and other transportation resources. The surviving bell therefore provides a rare physical link to the transportation and administrative systems of ancient Japan.
Because so few examples have survived, the eki-rei is of exceptional historical interest. For international visitors, it offers a fascinating reminder that the remote Oki Islands were nevertheless connected to Japan’s sophisticated centralized governmental system more than a thousand years ago.
The Okiso-in Seal
Another important artifact is the Okiso-in, a seal associated with the administration and management of government storehouses in ancient Oki.
Only a small number of comparable seals are known to survive in Japan. The artifact provides valuable clues about the systems used to manage goods and supplies and illustrates the administrative structures that supported life in Oki Province.
Other Historical Objects
The collection also includes other historical materials, such as karabitsu, traditional storage chests. Together, these objects reflect the long history of the Oki family and the family’s role in preserving artifacts connected with the island’s religious and administrative heritage.
A Historic Landscape with Tamawakasu-no-Mikoto Shrine
One of the greatest attractions of the Oki Family Residence and Treasure Hall is their close relationship with Tamawakasu-no-Mikoto Shrine. The shrine and the residence have been preserved side by side, creating a rare landscape in which a place of worship and the home of its hereditary priests can be understood together.
The thatched buildings, traditional architecture, sacred grounds, and surrounding greenery create an atmosphere that feels far removed from modern urban life. Walking between the shrine and the residence allows visitors to imagine how religious ceremonies, household life, and community affairs were intertwined in the past.
Historical construction documents preserved in connection with the shrine and its buildings also provide valuable information about traditional building techniques and the way religious facilities were maintained.
The Oki Family and the History of the Shrine
Tamawakasu-no-Mikoto Shrine has long been revered as the Soja, or provincial grand shrine, of Oki Province. The Oki family served as the hereditary priestly family responsible for its rituals and ceremonies.
The family is traditionally regarded as descending from the ancient kuni no miyatsuko, hereditary provincial leaders who played important administrative and religious roles in ancient Japan. Through their long service to the shrine, the Oki family became deeply connected with the religious history of the islands.
For this reason, the Oki Family Residence and Treasure Hall are more than a historic house and a collection of artifacts. They represent an important cultural crossroads where the religious, political, and social history of Oki comes together.
How to Experience the Oki Family Residence and Treasure Hall
Begin with Tamawakasu-no-Mikoto Shrine
A visit is best understood as part of a broader exploration of Tamawakasu-no-Mikoto Shrine. Beginning with the shrine allows visitors to appreciate the sacred setting before discovering the residence where generations of priests lived and carried out their duties.
Walking through the area in this order makes it easier to imagine the historic relationship between the shrine, its priests, and the local community.
Look Closely at the Architecture

Understand the Stories Behind the Artifacts
The eki-rei and Okiso-in become even more fascinating when viewed in their historical context. They are not simply old objects; they are physical evidence of the systems of transportation, administration, and distribution that connected Oki with the wider Japanese state.
