Former Sano Family Residence (Museum of Commercial and Domestic Life) Main House

A merchant house facing the old highway

The Former Sano Family Residence (Museum of Commercial and Domestic Life) Main House is a two-storey timber townhouse at 1938 Uchiko in Uchiko-cho, Kita-gun, Ehime Prefecture, built in the closing decades of the Edo period and entered on the national register of Registered Tangible Cultural Properties (structures) on December 3, 2024 (Reiwa 6). It was the principal building of the Sano family, who brewed sake and dealt in medicines.

The house stands with its front to the north, on the line of the old Ozu Kaido highway that runs through the middle of Uchiko. It has a gabled kirizuma roof of sangawara pantiles and a low secondary eave carried across the whole street frontage. The registered building area is 216 square meters. Seen from the road, the frontage reads in two bands: the shaded openings under the eave, and the plastered upper wall rising behind it.

What looks like one house is really two. A block of late Edo date, laid out with a through-passage earthen floor, stands beside a block added in 1910 with its earthen floor at the front. The two sit side by side on an east-west line and were reworked into a single building. The Agency for Cultural Affairs records the construction date within a range of 1830 to 1868, and folds the mid-Meiji alterations, the 1910 extension, the early Showa remodelling and a 1988 renovation into one registration.

Inside, a doma, or earthen-floored strip, runs along the east side, with two ranks of rooms to the west of it. In the southwest corner sits the best room of the house: a zashiki reception room with a tokonoma alcove, staggered display shelves, and a hirashoin. A hirashoin is a shallow writing bay lit through paper screens facing the veranda, distinguished from a tsukeshoin by having no desk board projecting forward.

Sake, medicine, and a second life as a museum

The Sano family traded in the Muikaichi district at the centre of Uchiko. They brewed sake; later they wholesaled and retailed medicines. A merchant house changing its stock over the generations was ordinary enough along a highway, and the "Former" in the name simply marks the end of the building's life as a family home.

That change came in 1986, when the town of Uchiko bought the land and the buildings. After survey and repair the compound reopened as the Uchiko Municipal Museum of History and Folklore, better known by its working name, the Museum of Commercial and Domestic Life. The working name is carried inside the parentheses of the official cultural property title, which is not a common arrangement.

The displays reconstruct the trade and daily life of a pharmacy around 1921, using life-size figures and period equipment. An apprentice greets visitors from the shopfront in the local dialect. Further in, a breakfast scene and a kitchen scene follow. The family sits on tatami; the servants eat a step lower on the earthen floor, and the household hierarchy is legible in the seating alone. Because the exhibition is built into the existing plan, following the sequence of rooms is also following the way the household actually moved through the house.

The 1988 work was carried out for this public opening. When the register lists the date of the building as including an early Showa remodelling and a 1988 renovation, it is pointing at both the prewar alterations and this late-Showa conversion.

Why this building was registered

Japan's registration system for buildings uses three criteria: contribution to the historic landscape of the country, value as a model of design, and difficulty of reproduction. The Former Sano Family Residence (Museum of Commercial and Domestic Life) Main House was registered under the second of these, as a model of design. Its registration number is 38-0194.

The storehouse and the detached wing on the same plot were both registered under the first criterion, contribution to the historic landscape. Three buildings entered the register on the same day under two different headings, and the split is worth carrying around the site. The main house was judged on the quality of the building itself, beyond its place in the streetscape.

Two things carry that judgement. The first is the southwest reception room, which assembles the full vocabulary of the shoin tradition: alcove, staggered shelves, and shallow writing bay. The second is the fused plan. As the family's business grew, the house was extended and then unified, and the sequence of that growth is still readable in the floor plan. The Agency for Cultural Affairs summarises the point by saying the building conveys the development of the town.

What to look at on site

The earthen floor along the east

The ground changes underfoot as soon as you step in. The earthen strip runs the depth of the plot along the east side, tying the shop space at the front to the service rooms at the back in a single line. In a machiya this strip is workspace, corridor, and social filter at once, keeping customers and family on separate tracks. Standing in it and looking up, you can see beams and roof framing at several points. Old timber and later repairs sit next to each other, and working out which is which is one way to read the age of the house.

The room in the southwest

The finest room is the one furthest from the street. With the front of the house given over to trade, the space for receiving guests retreats to the back, where it opens toward the garden. The proportions of the alcove and shelves, and the quality of light through the screens of the writing bay, show plainly where a merchant family chose to spend money.

Finding the join

Where do the Edo block and the 1910 block meet? Looking for the answer may be the most rewarding way to visit. Column spacing, beam heights, the way ceilings are boarded, differences in floor level: there are several clues, though the join was handled carefully enough that nothing announces itself. Upstairs, the framing is visible closer to the roof, and there is more to go on than on the ground floor.

The upper floor holds an eight-mat room with its own writing bay, the room the Agency for Cultural Affairs chose for its interior photograph. Second floors in townhouses were usually storage or servants' sleeping quarters. Fitting one out as a formal room was a statement about the standing of the household.

Visiting

The building is open all year as the Museum of Commercial and Domestic Life. Hours are 9:00 a.m. to 4:30 p.m. The only closures are December 29 to January 2. Admission is 200 yen for adults and 100 yen for children, with group rates of 150 and 80 yen.

A combined ticket covers three town-run sites: the Uchiko-za theatre, this museum, and the Kami-Haga Residence wax museum. The standard price is 900 yen for adults and 450 yen for children, but a reduced price of 700 and 350 yen (590 and 300 yen for groups) applies from August 1, 2025 until the end of 2028. Tickets are sold at each site.

Trains are the simplest approach. From JR Uchiko Station on the Yosan Line, walk north along Honmachi-dori for about ten minutes; the building is on the right, identifiable by the two life-size figures standing at the shopfront. Limited express trains from Matsuyama take roughly 25 to 30 minutes. Drivers should use the Uchiko-Ikazaki interchange on the Matsuyama Expressway. The address is 1938 Uchiko, Uchiko-cho, and the telephone number is 0893-44-5220.

The town publishes no photography policy for the interior. Special exhibitions may include loaned material with restrictions, so ask at the reception desk when you pay. A special exhibition is mounted roughly once a year and changes how parts of the house are presented.
