The Kumagaya Family Residence is an architectural masterpiece from the late Edo period located in Ota City, Shimane Prefecture. It was designated as a National Important Cultural Property in 1998, reflecting the prestige of a merchant family that managed the Iwami Silver Mine and held official positions in the local administration. The estate features a main house surrounded by white plaster walls and five distinct storehouses (North Tool Store, Small Store, Clothing Store, East Tool Store, and Rice/Miscellaneous Store), vividly illustrating the daily life of wealthy merchants of that era. As a component of the UNESCO World Heritage site 'Iwami Silver Mine and its Cultural Landscape,' the residence holds immense historical and cultural value.
The Kumagaya family was a highly prestigious lineage, deeply involved in the management of the silver mine and serving as 'Kakeya' (officials in charge of public funds) and 'Machitoshi' (town officials). The foundations of the current structure were rebuilt following a major fire in 1800 (Kansei 12) and were further refined through the early Meiji period. The architectural design of the main house and the layout of the grounds reflect the status of the family, serving as a symbol of the political and economic center of the region rather than just a simple residence. Through careful preservation and restoration, the site maintains its appearance from the late Edo to early Meiji periods.

The greatest charm lies in the profound architectural style that has endured for over 220 years. Stepping into the 'Doma' (earthen floor) of the main house, you are greeted by a powerful yet serene space shaped by thick pine beams, massive zelkova pillars, and cedar sliding doors. The five specialized storehouses scattered across the grounds tell stories of how goods and resources were managed during the era. Additionally, the beauty of the Sekishu-style tiled roofs, the white plaster walls, and the way the estate harmonizes with the natural scenery of the Ginyu River will transport you back to the Edo period.
The residence offers different-looking-expressions depending on the season. Visiting during periods when seasonal decorations or traditional household items are on display provides a deeper understanding of historical lifestyles. The bright daylight hours are ideal for appreciating the architectural beauty, as the natural light highlights the textures of the beams and the depth of the earthen floor. A clear, sunny day is highly recommended to enjoy the harmony between the architecture and the surrounding natural landscape.

Beyond simple sightseeing, the site occasionally hosts various cultural events utilizing the heritage space. Through exhibits that convey the lifestyle of influential merchants, visitors can experience history firsthand. The area around the residence is rich with opportunities to connect with local culture, much like the rest of the Iwami Silver Mine area. Within this tranquil historical space, you can learn about traditional Japanese architectural techniques and ways of life.
The Kumagaya Family Residence is situated within the historic streetscape of the Iwami Silver Mine World Heritage site. The nearby Omori Town is perfect for strolling through charming, traditional streets. Other facilities, such as the Iwami Silver Mine World Heritage Center, are also nearby, offering further historical learning. You can enjoy the harmony of history and nature while exploring local cafes and dining spots in the vicinity.
To protect the historical structure, visitors are required to remove their shoes before entering the buildings. We recommend wearing shoes that are easy to slip on and off, and dressing appropriately for the season. To preserve the landscape and the integrity of the cultural property, please follow all local rules. Avoid touching the exhibits or the building structures and maintain a quiet demeanor to respect the historical atmosphere.
