A Merchant House Built in 1935 That Refused to Look Modern
Okusho Store and Main House (奥庄店舗兼主屋, Okusho Tenpo ken Shuoku) is a two-storey timber merchant house facing south onto Omachi street in Yuki City, Ibaraki Prefecture, built in 1935 and entered on the national list as a Registered Tangible Cultural Property on 8 January 2009.
The date is the interesting part. By the mid 1930s a prosperous provincial merchant who wanted a new shop had other options. Reinforced concrete had arrived, and towns across the Kanto plain were putting up flat-fronted commercial buildings finished in mortar and sheet metal. The family behind this frontage chose none of that. They built a Machiya, gabled and eaves-entered under pantiles, with the projecting purlin eaves of a nineteenth-century shop. The Agency for Cultural Affairs, describing it, says the building preserves the bearing of a traditional merchant house, and registration followed under the criterion for works that set a standard of design.
The firm is older than the building by a century. Yuki City records that Okusho traces its founding to 1831, trading for generations as Sawaya Shobei and dealing in Yuki tsumugi silk. The move to this site and the raising of this shop came in 1935, in the time of the previous head of the house. The name Okusho itself dates only from 1963.
How the Building Is Put Together
Okusho Store and Main House is really two volumes in line. The street block measures 4 Ken along the ridge by 3 ken deep and holds the shop. Behind it, connected directly, a second block of 4 and a half ken by 3 ken holds the Zashiki reception rooms and the living quarters. The Agency for Cultural Affairs describes the rear as a two-storey wing set at right angles to the front. Building area comes to 84 square metres.
A third piece joins on the east, a two-storey addition 1 and a half ken wide. Yuki City dates it to 1943 and gives the reason: a senior army officer was billeted on its upper floor. It is a small thing, easy to miss from the pavement, and it is the only part of the building that carries the war on its face. A further refurbishment followed in 1976.
The plan is the ordinary sequence of a Japanese shop house, trade at the front and family behind, but the front block does something specific. The ground floor is carried on two free-standing posts, and the whole width between and beside them is filled with sliding wooden-framed glass doors. Above, a small canopy runs on projecting purlins. The upper floor repeats the move: half-ken shutter boxes at either end, sliding wooden-framed glass windows across everything in between.
Glass, Tile and the Look of the Street
Stand across Omachi street and the elevation reads as glass held in a timber grid. Very little wall is doing visible work on the front of Okusho Store and Main House. That openness is the point: a silk wholesaler needs even daylight to judge cloth by, and glass by the 1930s was cheap enough to glaze a whole frontage.
Then lift your eyes to the roof, where the building spends its money on tradition instead. The ridge is built up in stacked noshi tiles, and at each end sits a kagemori tile with an ridge-end tile beyond it. The eaves are carried forward on dashigeta, the projecting purlin that gives an old Kanto shop its deep shadow line. The lower part of the elevation belongs to the twentieth century and the upper part does not, and nobody involved seems to have thought that a problem.
Yuki City reports the fabric as very well preserved overall, both inside and out, with one honest exception: the west flank has been sheathed in iron sheet. Side walls are where Japanese merchant houses are usually patched, since only the front was ever meant to be looked at.
Omachi street is worth walking in its own right. Yuki City notes that its historic quarter is characterised by misegura, shops built with the thick earthen walls of a storehouse, raised from the early Meiji era through the Taisho period along this street and the road to the station. Okusho Store and Main House is the later, timber-and-glass answer to the same street, standing on the north side and facing the sun.
Visiting Okusho Store and Main House
Okusho Store and Main House is a working commercial building in private hands. There is no admission charge because there is no admission: neither Yuki City nor the operator publishes any arrangement for going inside, and visitors should plan on seeing the exterior from Omachi street.
That is less of a limitation than it sounds. The registered qualities of the building are almost all on the south elevation and the roofline, and the street is wide enough to take them in. Photographing from the public road is unrestricted, though the shop is someone's place of business and the ordinary courtesies apply. There is no fixed viewing time; daylight from the south favours the afternoon.
From the north exit of Yuki Station on the JR Mito Line, Omachi street is about 10 minutes on foot. The Okujun buildings, four of them registered on the same street, stand a short walk to the west, so the two frontages can be compared in a single outing. Access details were checked on 6 September 2026.

Q&A
- Can I go inside Okusho Store and Main House?
- No public opening is arranged. The building is privately owned and in commercial use, and neither the city nor the operator advertises interior access. The south elevation and the roof, which carry the features the registration rests on, are fully visible from Omachi street.
- When was Okusho Store and Main House built, and when was it registered?

- Why does Okusho Store and Main House have a narrow wing on its east side?
- The two-storey addition, 1 and a half ken wide, was built in 1943 so that a senior army officer could be accommodated on its upper floor. Yuki City records this directly, and it is the only element of the building that reflects the war years.
