A Farmhouse Shell Around a Doctor's Practice
The Rikyudo Sakai Family Residence Main House (利久堂酒井家住宅主屋, Rikyūdō Sakai-ke Jūtaku Shuoku) is a wooden house in Kawai Shinden, Nagano City, built around 1887 and registered as a Registered Tangible Cultural Property of Japan in 2001. It was built for the Kitamura family, an established local household that practiced medicine here from the Meiji era onward.
The house is mostly single-storey with a partial upper floor, roofed in tile, and covers 283 square meters. The Hachijuni Culture Foundation, which keeps a prefecture-supervised record of Nagano's heritage, describes a gabled Kirizuma-zukuri roof of Sangawara-buki pantiles topped by a raised ventilating ridge. The Main House sits at the center of the compound, with the Nagayamon Gate to the south and the two storehouses to the northwest.
From the road it looks like a farmhouse. Inside, it was a clinic.
Why the Floor Plan Counts as a Model
The Rikyudo Sakai Family Residence Main House holds registration number 20-0100 under the criterion of serving as a model of its building type. The Agency for Cultural Affairs singles out three things: the silk-farmhouse exterior with its raised ridge, a formal entrance placed at the center of the front, and an irregular plan that absorbs a medical practice.
That plan is the heart of the case. At the upper end of the house, the side traditionally reserved for guests, the principal Zashiki reception room sits in the middle, with a corridor-like strip called an irikawa on both its front and back. At the opposite, lower end, an examination room and a waiting room open off the earth-floored Doma. One reading is that the house sorted its visitors: formal guests toward the reception rooms, patients toward the working side.
Retirement quarters and other rooms project from the rear. The plan keeps the bones of a local farmhouse and rearranges them around a country doctor's life.
What to Notice at the Rikyudo Sakai Family Residence Main House
Start with the roofline. The ventilating ridge, known as a koshi-yane, is a second, smaller roof set over the main ridge, with a gap between the two that lets heat and damp escape. In silk-producing districts this was the standard way to air the rooms where silkworms were raised. Its presence on a doctor's house shows the Kitamura family building in the same vocabulary as the farming households around them.
Then the center of the facade. The entrance has a Shikidai, a low boarded step used to receive visitors of standing. Records do not say who used it in a house that doubled as a clinic.
Inside, the telling detail is where the clinic sits. In a farmhouse the doma is usually the kitchen and work area. Here the examination and waiting rooms adjoin its lower side, so everyday household work and medical care met across the same earthen floor, while the reception room at the other end kept its formal corridors on both sides.
Seeing the Rikyudo Sakai Family Residence Main House
The Rikyudo Sakai Family Residence Main House is a private home, and no public opening of the interior has been announced (checked September 2026). The layout described above is known from the Agency for Cultural Affairs record, not from visits.
The house stands behind the Nagayamon Gate, deeper into the grounds. Seen from the south, the gate roof overlaps it, so the part most likely to be recognizable from outside is the raised ridge. Stay off the property, photograph only from outside it, and avoid capturing residents.
Inquiries go to the Cultural Properties Division of Nagano City. Directions to the compound and general visiting notes are on the Rikyudo Sakai Family Residence page.
