A Soy-Brewing Townhouse on the Ina Highway
The Kitaya Arai Family Residence Main House (喜多屋新井家住宅主屋, Kitaya Arai-ke Jūtaku Omoya) is a late Edo-period merchant townhouse standing on the old Ina Highway in Miyada Village, Kamiina District, Nagano Prefecture, registered as a Tangible Cultural Property of Japan on 31 October 2022.
The first thing to sort out is the name, because Miyada has two protected buildings connected to families called Arai and they are not the same place. The one described here is a private house identified by its shop name, Kitaya. The other is the Miyada-juku Honjin Former Arai Residence, the official lodging where travelling lords stopped, which carries prefectural treasure status and admits visitors free of charge. Confusing the two is easy and the guidebooks do not always help.
Shop names mattered in a post town. Surnames were shared across dozens of households along a single street, so a business went by its yagō, its trading name, painted on the entrance curtain and used by everyone in daily speech. Kitaya was a soy sauce brewery.
Miyada-juku served the Ina Highway, the road running the length of the Ina Valley between the Central and Southern Japanese Alps. The village stood at the southern edge of the Takato domain's territory, and it was one of the relatively few stops on this road important enough to hold a honjin. Immediately south, the Otagiri River cut across the route, a crossing with a reputation for turning dangerous in spate.
The main house dates to the latter half of the Edo period, placed by the Agency for Cultural Affairs between 1751 and 1830. It was worked on again in the late 1930s, in 1954 and in 1975.
How the Building Is Put Together
The house faces west onto the road, two storeys under a gabled roof, entered from the long eaves side in the arrangement Japanese carpentry calls hirairi. Ground coverage is 263 square metres, and the roof is sheet metal, replacing what would once have been shingle or thatch.
Two features give the building its character on the street, and both concern proportion rather than ornament.
The eaves are low. The frontage is long. Standing in the road you see a horizontal band of building that continues past where you expect it to stop, held down by a roofline that sits closer to the ground than a modern eye anticipates. Post towns produced this shape because plots were narrow at the front and deep behind, and because a low profile suited buildings that had to shrug off snow and wind coming down off the mountains.
Along the northern edge stands the omote-gura, the front storehouse used for soy sauce brewing, and the sheet-metal roof is carried across house and storehouse as a single unbroken plane. That continuity is what registration singled out. A brewery storehouse would normally read as a separate mass with its own roof; joining the two produces one long silhouette in which the working part of the property and the living part cannot be visually separated.
Inside, the division runs north to south. The northern strip is doma, packed earth floor, the surface on which brewing, cooking and cartage happened, walked on in outdoor footwear. South of it the floor lifts to boards and mats, the yukaue living zone. Only the front portion carries a second storey; behind that, the roof runs over a single-height space. In the south-west corner sit a butsuma, the room holding the family Buddhist altar, and a formal reception room fitted with a tokonoma, the recessed alcove where a hanging scroll and a seasonal arrangement are displayed.
Put those together and the plan is legible as a diagram of the household. Work at the north, in the dirt. Family life in the middle. Ancestors and guests at the far south-west corner, furthest from the noise and the smell of the mash.
Seeing It, and Seeing the Street It Belongs To
The Kitaya Arai Family Residence Main House is lived in and is not open to visitors. There is no admission, no interior tour and no published opening period. The street frontage can be looked at from the public road, and that is the extent of it. Photographing the exterior from the road is not restricted, though pointing a lens into a private entrance is discourteous anywhere.
The building rewards a slow walk more than a single stop, because it was registered as part of a group. Five historic structures along Miyada-juku entered the national register together in 2022: this main house, the Kyoguchiya Sumiya Residence Main House, the Ebisuya Hara Residence Main House and its storehouse, and the south storehouse of the Masakiya Yamaura Residence. Read them in sequence and the economic range of one post town becomes visible, since among them are a former restaurant, a former inn and a sake brewer's storehouse with painted decoration on its interior fittings.
The old street runs roughly a kilometre. Tsushima Shrine anchors one end and serves as the gathering point for local heritage walks; its Gion festival is known for a rite in which the portable shrine is deliberately smashed. Miyada Village Library has run guided sessions along this route with a curator from the village board of education, which is the best way to get inside the story if the timing works.
Getting there is straightforward. Miyada Station on the JR Iida Line sits in the village, within walking distance of the old highway, and the Ina Valley is easily reached by road from the Chuo Expressway. Come on a clear day in autumn or winter and Kiso-Komagatake rises white behind the rooftops to the west, which is the view the people who built these houses had every morning.
Anyone with an interest in the wider context should also visit the honjin building mentioned earlier, which is open at no charge and shows an Edo-period interior that a private house like Kitaya cannot.
