A Meiji house facing south from the foot of the hill
The Itani Family Residence Main House (井谷家住宅主屋, Itani-ke Jūtaku Shuoku) is a single-storey wooden dwelling of about 1893 in Shimokagiyama, Kihoku Town, Ehime Prefecture, entered on the national register as a Registered Tangible Cultural Property (building) on 13 August 2012.
The house sits on ground levelled out of the hillside and faces south. It is timber-framed, single-storey, with a building area of 236 square metres, a gabled roof laid in pantiles, and a smaller gabled entrance porch pushed forward at the centre of the front. For a one-storey building it is large. Standing in front of it, you see one long ridge line running the width of the house, with the little gable of the porch breaking out ahead of it.
Shimokagiyama was the seat of the village office of Hiyoshi Village until 2005, when Hiyoshi merged with Hiromi to form the present Kihoku Town. Houses run in a thin line along the road on the valley floor cut by the Hiromi River. The Ehime prefectural history volume on the Nanyo region records that this roadside settlement was laid out deliberately from the closing years of the Meiji era by a local man, Itani Masamichi. Born into the headman's household of Hyūgadani, Masamichi was chosen as the first mayor of the newly created Hiyoshi Village when the municipal system took effect in 1890, and he pressed for a road linking Uwajima with Susaki in Kōchi Prefecture.
When the Itani Family Residence Main House went up around 1893, that road had not been started. Work on the Hiyoshi route began in 1902, some nine years later. No primary source consulted here states the relationship between Masamichi and the household that built the house, so the two facts are set side by side rather than joined.
Why it was registered, and what the plan says
The criterion applied was the one covering buildings that contribute to the historic landscape of the country. What earned the listing was not rarity of form but the part the house plays in holding the local scene together. The Agency for Cultural Affairs describes it as a Japanese-style dwelling that shows one aspect of modernisation in this district.
Anyone expecting Western detailing from the word modernisation will find the building quiet. Posts and roof are conventional Japanese work. Modernisation here shows up in scale and in how the rooms are sorted, not in ornament.
The argument sits in the floor plan. The front row, extending east and west from the entrance, holds the guest room, the master's room and the retirement room, all carefully finished and set side by side. The back row takes the kitchen and the other inward-facing rooms. Front for the outside world, back for daily life. That two-row division is the plan of a household that absorbed the village's negotiations and business into its own reception rooms.
In a mountain village, few families could put up a single-storey house with several formal rooms lined up in a row. The figure of 236 square metres states the point plainly.
What to look at
From the front, the porch gable takes the eye first. Pushing a small gable forward, separate from the main roof, is a device used on houses of standing. Both roofs are laid in pantiles, and the tile courses of house and porch meet at an angle. How that junction is resolved can be read from the road without entering the grounds.
Then look at the relationship between building and ground. The Itani Family Residence Main House does not stand on flat land. It rests on a platform carved from the foot of the hill. That platform is held up from the south by the south stone wall, registered on the same day, and the stone wall and earthen wall run left and right from the stone steps in front of the entrance. Looking at this house means looking at a house built on earthworks.
On the west side stands the storehouse, joined to the dwelling by a covered passage. Linking house and storehouse with a passage is a practical answer to the heavy rainfall of the Nanyo region, where a storehouse still has to be opened and closed every day.
The condition today is not good. At the December 2025 session of the Kihoku Town assembly, damage from rain leaks was raised in a general question. Visitors will be looking at a building waiting for repair.
Visiting
The Itani Family Residence Main House is not a visitor attraction with regular opening. The interior is not open to the public, and there is no admission fee or published opening time.
Kihoku Town acquired the land and buildings in fiscal 2017. According to the town, deterioration was already advanced at the time of acquisition and full preservation work was needed. A study committee on the preservation and use of the Itani Family Residence was set up in fiscal 2019, and a preservation and utilisation plan was adopted in fiscal 2023. Detailed design for the repair work is now under way. Anyone hoping to see the site should contact the Kihoku Town Board of Education in advance on 0895-45-1111.
Photographing the exterior from the public road is no different from photographing any streetscape. Entering the grounds to photograph requires the town's permission, not least because work is in progress.
For access, the nearest railway station is Chikanaga on the JR Yodo Line. From the station, an Uwajima Jidosha bus takes about 35 minutes to the Kihoku Town Hall Hiyoshi Branch stop. Services are infrequent, so check return times before setting out. By car, National Route 197 passes through Shimokagiyama.
