The History of the Muneoka Family
The ancestors of the Muneoka family served the Mori clan during the Sengoku period and became deeply involved in the administration of Iwami Ginzan. The family’s first known head, Muneoka Yaemon, was particularly respected for his knowledge of silver-mine management and mining techniques.
Service Under the Tokugawa Shogunate
After Tokugawa Ieyasu established the Edo shogunate, Iwami Ginzan came under the direct control of the shogunate. At this time, Muneoka Yaemon was recognized by Okubo Nagayasu, the first magistrate of Iwami Ginzan, and was appointed to an important position involved in governing the mine.
Muneoka Yaemon is also said to have participated in the development of the Sado gold and silver mines. In recognition of his achievements, he reportedly received the title “Sado.”
The Muneoka family continued to serve in the administration of Iwami Ginzan, including responsibilities related to tax collection and local governance. For generations, the family played an important role in the development of Omori and the mining district.
Traditional Architecture of a Samurai Residence
The Former Muneoka Residence has a formal architectural style characteristic of a samurai household. At the front of the main building is a shikidai entrance, a formal entrance associated with samurai residences. Beside it is a large doorway known as the ōtoguchi.
These features immediately distinguish the residence from ordinary homes and merchant houses and reflect the social position of the people who lived here.
Simple Elegance of the Main Building
The main building is a single-story structure with a gabled roof covered with traditional tiles. Its restrained appearance, white plaster walls, and Sekishu roof tiles blend beautifully with the historic streetscape of Omori.
The combination of dark timber, white walls, and traditional roof tiles creates an understated elegance that is characteristic of historic buildings in the San’in region.
The Only Remaining Detached Building in the Area
One of the most notable features of the Former Muneoka Residence is its detached building, or hanare. Among the samurai residences in this historic district, it is the only one known to retain such a detached structure.
The residence originally consisted not only of the main house but also a detached building, garden, and storehouse. This larger compound reflects the status and lifestyle of the Muneoka family as local officials connected with the silver mine.
Stay in a Historic Samurai Residence
The detached building is now used as accommodation under the name Manabi-no-Yado Muneoka. This allows visitors to do more than simply view a historic building—they can experience staying overnight in an atmosphere closely connected with traditional Japanese architecture.
Spending time in the quiet setting of a renovated traditional house offers a different perspective on the history of Iwami Ginzan. The scent of tatami, the warmth of wooden architecture, and the soft light filtering through traditional paper screens create an atmosphere far removed from modern everyday life.
Exquisite Transom Carvings
Another detail worth looking for is the beautifully crafted ranma, the decorative openwork transom installed between the rooms leading toward the inner reception room.
The carvings feature designs such as a waterwheel with a bamboo-and-stone riverbank structure and a waterwheel with a bridge. Their delicate patterns demonstrate the high level of craftsmanship achieved by artisans during the Edo period.
Although the residence was a samurai household, these elegant decorative details reveal an appreciation for beauty and craftsmanship, offering a glimpse into the cultural refinement of the people who lived here.
Manabi-no-Yado Muneoka
An Immersive Stay in a Historic Japanese House
Following renovations completed in 2018, the residence began serving as Manabi-no-Yado Muneoka. It functions not simply as accommodation but as a place where guests can learn about the history and culture of Iwami Ginzan while experiencing life in a traditional house.
The peaceful interior makes it easy to slow down and appreciate the details of traditional Japanese living. Tatami floors, wooden structures, sliding doors, and gentle natural light create a quiet environment in which the atmosphere of the past can be experienced directly.
Omori After Dark
Staying overnight also provides an opportunity to see Omori from a different perspective. After most visitors have left for the day, the historic streets become remarkably quiet.
Under the moonlight, the old houses and traditional Sekishu-tile roofs take on a particularly atmospheric appearance. Walking through the peaceful streets at night can feel like stepping into another era.
Exploring Historic Omori
A Townscape Preserved from the Edo Period
The Muneoka Residence stands in Omori, which developed as the administrative and commercial center of Iwami Ginzan. Much of the historic townscape has been carefully preserved, making the area particularly rewarding to explore on foot.
One of Omori’s most distinctive characteristics is the close proximity of samurai residences, merchant houses, temples, and shrines. Unlike a typical castle town, people from different social backgrounds lived and worked in close proximity here because of the unique demands of the silver-mining community.
This mixture of buildings and lifestyles gives Omori a character quite different from other historic towns in Japan.
The Warm Colors of Sekishu Roof Tiles
Traditional Sekishu tiles are another defining feature of the townscape. Made from clay containing a high proportion of iron, these tiles develop their characteristic reddish-brown color and are known for their durability.
The warm color of the tiles contrasts with the gray tiles traditionally used on samurai residences and administrative buildings. Paying attention to these differences while walking through Omori provides an interesting way to understand the social and architectural distinctions of the Edo period.
Nearby Attractions
Ryugenji Mabu
Ryugenji Mabu is one of the most important places to visit when exploring Iwami Ginzan. This historic mine tunnel was excavated during the Edo period, and traces left by miners’ tools can still be seen inside.
Walking through the tunnel provides a direct connection with the difficult underground work that supported the prosperity of Iwami Ginzan.
Former Kumagai Residence
The Former Kumagai Residence is one of the largest merchant houses in Omori. The extensive residence preserves the lifestyle of a wealthy merchant family.
Visiting both the Muneoka and Kumagai residences offers an opportunity to compare the different living environments and cultures of samurai officials and prosperous merchants in the historic mining town.
Kigami Shrine
Kigami Shrine stands near the entrance to Omori and is known for its famous “Singing Dragon” ceiling painting. When visitors clap their hands beneath the painting in the worship hall, the sound reverberates through the building as though the dragon were calling back.
The shrine is an atmospheric addition to a walking tour of Omori and provides another perspective on the religious and cultural traditions that developed alongside the silver mine.
A Journey Through History and Everyday Life
The Former Muneoka Residence is much more than an old house. It preserves the story of the people who supported the prosperity of Iwami Ginzan and offers insights into the social structure, craftsmanship, aesthetics, and everyday life of the Edo period.
Standing inside the quiet samurai residence, it is easy to imagine the officials and their families who once lived here while carrying out their responsibilities in the silver-mining district.
Combining a visit to the residence with a walk through the historic streets of Omori makes it possible to understand Iwami Ginzan from a human perspective—not only as an important mining site, but also as a living community where officials, merchants, craftsmen, miners, and other residents shared their daily lives.
With its historic streets, distinctive Sekishu roof tiles, peaceful mountain setting, and elegant samurai architecture, the Former Muneoka Residence offers a particularly tranquil way to experience the heritage of Iwami Ginzan. It is an appealing destination for travelers interested in Japanese history, traditional architecture, old houses, and cultural experiences.
