Shibue Family Main Building

A Taisho Townhouse East of the Asano River

Shibue Family Main Building (澁江家住宅主屋, Shibue-ke Jūtaku Shuoku) is a townhouse in Higashiyama 1-chōme, Kanazawa, Ishikawa Prefecture, built in 1921 and entered on Japan's national register of Tangible Cultural Properties on 9 June 2004. It is a two-storey wooden structure with a tile roof and a footprint of 62 square metres. The first character of the family name, 澁, is the older written form of 渋; both are read Shibue.

Higashiyama 1-chōme occupies the east bank of the Asano River, immediately across the Asanogawa Ohashi bridge from central Kanazawa. Most visitors know the address for one reason: Higashi Chaya, the teahouse quarter licensed by the Kaga domain in 1820 and selected in 2001 as a national Preservation District for Groups of Historic Buildings. Wrapping around it to the north and east lies a second such district, Utatsusan-roku, selected in 2011 and built around the temple town at the foot of Mount Utatsu. Two preservation districts of quite different character fall within this one small chōme.

Shibue Family Main Building stands at number 4, on the side nearer the bridge. This is neither the run of lacquered lattice frontages that draws photographers to the teahouse streets, nor the temple approaches climbing the hillside. It belongs to the flat blocks extending from the old Hokkoku Kaidō highway, where ordinary townhouses stood eave to eave.

The Agency for Cultural Affairs classifies the building under tertiary industry rather than housing. That administrative category says something real about it. A machiya was never simply a residence; it presented a working face to the street while accommodating family life behind and above.

Valued for What It Does to the Street

Registration in Japan operates against three criteria: contribution to the historic character of the national landscape, excellence as a model of design, and difficulty of reproduction. Shibue Family Main Building entered under the first.

That choice is worth pausing on, because it shifts the basis of evaluation. A building registered for design excellence is judged on the quality of its own construction. A building registered for landscape contribution is judged on how it stands to the street and how it functions as one member of a townscape. Other registered properties in Kanazawa were assessed the other way; comparing the criteria tells you what the assessors were actually looking at.

Here they were looking at a hirairi frontage facing west onto the road. Hirairi means the building is entered from its long side, the wall running parallel to the roof ridge, as distinct from tsumairi entry through the gable end. A hirairi house presents a wide face, aligns its eave line easily with its neighbours, and repeats comfortably down a block. Where townhouses form a continuous street, hirairi is the underlying grammar.

The registration number is 17-0104, from the forty-second round, announced on 24 June 2004. Sato Family Main House in the Jūichiya-machi district of the same city was registered on that date as well: a Taisho townhouse and a prewar Shōwa restaurant building entering together, two layers of how modern Kanazawa lived and traded.

Registration carries lighter obligations than designation. Owners of Important Cultural Properties must obtain permission before altering anything; registered owners file a notification when changing more than a quarter of the exterior. The system was built so that people could go on living in these buildings and maintaining them.

Doubled Brackets, and a Sitting Room Facing the Mountain

Look up from the street and the second-floor roof dominates. It is built degeta-zukuri, a construction in which the purlin is carried out beyond the wall plane on projecting udegi brackets to support a deep overhanging eave. Kanazawa townhouses used this arrangement as a matter of course.

What sets this house apart is that the brackets are doubled, stacked in two tiers where one would have sufficed. The second tier does little structurally. What it does is thicken the shadow under the eave, layering it. Late in the afternoon, when light comes in at an angle, the stacked brackets throw two lines of shade instead of one. This is the detail the Agency's description singles out as elaborated.

The plan is compact. On the ground floor the entrance sits toward the south, with living rooms including a chanoma, the everyday family room, arranged behind it. Upstairs, the principal sitting room takes an engawa veranda along its east side, with two antechambers in front of it and a nando storeroom beyond. At 62 square metres the building has the smallest footprint among Kanazawa's registered residences discussed here, a direct consequence of the narrow, deep machiya lot.

The vertical arrangement rewards attention. The formal room went upstairs, and its veranda faces east, toward Mount Utatsu. The ground floor turns west to the street, doing the work of trade and daily life; the upper room withdraws from that and looks to the hillside instead. Public and private, road and mountain, sorted by storey on a plot that offered no room to sort them any other way.

Visiting requires realistic expectations. The building is privately owned, the interior is not open, and the grounds cannot be entered. The exterior, seen from the public road, is all that is available. For anyone already walking the teahouse district, the nearest Hokutetsu bus stop is Hashiba-chō, a few minutes on foot after crossing the Asanogawa Ohashi bridge. That bridge is itself a registered Tangible Cultural Property, listed in 2000, so the approach is part of the walk. Photograph from the roadway if you wish, remembering that people live here.
