Shimada Family Residence Main House

A Timber Merchant's House Built from the Valley It Stands In

The Shimada Family Residence Main House (島田家住宅主屋, Shimada-ke Jūtaku Omoya) is a single-storey wooden house of 1941 on the main street of central Furano, Hokkaido, registered as a National Registered Tangible Cultural Property on 6 March 2024. It was built for an executive of a local sawmill, and the timber in it came from the forests of the Furano basin.

That last point carries more weight than it might seem. Furano sits in the middle of Hokkaido, ringed by the Tokachi range and the Yūbari mountains, and its economy in the prewar decades ran on lumber as much as on farming. A sawmill man building his own house had first refusal on the best boards that passed through his yard. The registration documents describe the material simply as good local timber, and the phrase is doing real work.

The house covers about 130 square metres of ground area. An extension was added around 1953.

Reading the Design

The Agency for Cultural Affairs registered the house under the criterion "a model of design." What earned that assessment is a set of choices that hold together rather than any single feature.

The roof is irimoya, hipped at the lower slopes and gabled at the ridge, and it is pitched shallow. Hokkaido roofs usually run steep to shed snow; a low irimoya over a house in a snow country town is a deliberate move toward the proportions of a Kyoto or Kanazawa building. It is covered in sheet iron rather than tile, which is the practical concession.

The walls use shinkabe construction, leaving the structural posts visible on the exterior surface instead of burying them in plaster. Below the wall line, the skirting is finished in sasarako shitami, a horizontal clapboard held by vertical battens that have been notched along their edges so each board seats into the cut. It is fiddly carpentry and it reads, at a glance, as a fine ribbed texture running around the base of the house.

Inside, the plan is the chūrōka type common to good houses of the 1930s and 1940s: an entrance on the east, a corridor running down the centre of the building, and rooms opening off both sides. Three tatami rooms are set in a row along the south front, arranged as continuous reception space with an engawa veranda in front of them. South-facing rooms with a veranda catch what winter light Furano gets, and there is not much of it in January.

The house is Furano's only nationally registered cultural property. It reached the list after the Council for Cultural Affairs recommended it on 24 November 2023.

Before You Go

This is a private house and it remains in private ownership. There is no admission counter, no opening hours and no interior tour. Nothing published by the city or the Agency for Cultural Affairs indicates that the building is open to visitors, and the descriptions of the corridor, the tatami rooms and the veranda come from survey records rather than from public viewing.

What a visitor can reasonably do is look at the exterior from the public street, which is where the shallow roofline and the notched clapboard skirting are visible anyway. Furano's main street runs a short walk from JR Furano Station on the Nemuro Main Line, and Wakamatsu-chō is within the central grid. Keep to the pavement, do not photograph into the grounds, and treat the household's privacy as the first consideration.

For context on the town's other buildings, the Furano Museum publishes a walking map of historic structures and a general history trail map, both downloadable from the city website. Those are the sensible starting point for anyone planning an architectural walk through the town rather than a single-building visit.

Furano is better known abroad for lavender fields and ski slopes. The house sits in the ordinary commercial centre that those visitors usually pass through on the way somewhere else.
