A brewer's house on the road at Kō
The Shirai Family Residence Main House (白井家住宅主屋, Shirai-ke Jūtaku Shuoku) is a late Edo-period townhouse in Kō-chō, Toyokawa, Aichi Prefecture, entered on the national register as a Registered Tangible Cultural Property in 2004. The Agency for Cultural Affairs records it as the main house of a sake brewery, built somewhere between 1830 and 1867.
The name of the district is worth pausing over. Kō is written with the characters for a provincial government seat, and Toyokawa was where the administration of Mikawa Province once sat. The Shirai house has nothing to do with that ancient office, but it stands on ground that had been the local centre of things for a very long time before a brewer built here.
The building presents its long side to the road and faces north, which makes it a Hirairi Machiya. Its frontage runs 8 Ken, and the depth is more than 6 ken. The registered floor area is 236 square metres. For a country town that is a large house, and the scale is the first thing the Agency's own description remarks on.
Why the Shirai Family Residence Main House was registered
Registration in 2004 was made under the criterion of contributing to the historic landscape of Japan. That criterion rewards buildings that hold the character of a place together, and it fits a house whose value lies less in any single rare feature than in the completeness of a common type.
The type is the brewer's townhouse of the late Edo period, and the Shirai Family Residence Main House keeps its parts intact. Roof, plan, and street face all belong to the same moment. The register number is 23-0137, in the 43rd round of registrations; the entry was made on 23 July 2004 and gazetted the following month.
A registered property is not the same thing as a designated one. Registration is a lighter system, created in 1996, that asks owners to notify the authorities before major alterations rather than to seek permission for every repair. It was designed for exactly this class of building: privately owned, still lived in, and vulnerable to quiet demolition rather than to any dramatic threat.
What to look for
Start with the roof. It is Kirizuma-zukuri, gabled, and covered in Sangawara-buki pantiles, and the second storey beneath it is a Tsushi-nikai: a low half-floor used for storage rather than living, with a ceiling too shallow to stand up in comfortably. Houses of this kind read as two storeys from the street and as one and a half from inside.
The ground floor carries a tiled Geya, a lean-to that runs along the front and shelters the wall behind it. Latticework is fitted into that sheltered strip. Above, the second storey is finished with a projecting lattice, the boxed-out grille that Japanese carpenters call degōshi. Two bands of lattice, one recessed under the lean-to and one pushed forward above it, give the façade its rhythm.
The plan is legible even from outside if you know where the divisions fall. The eastern end of the house is the Toriniwa, the earth-floored corridor that runs the full depth of the building. Brewing families needed that passage: it took barrels, buckets and people through the house without anyone stepping onto matting. West of it the living rooms are arranged in 2 rows of 3, making 6 rooms in all.
Then the roofline drops. A Buddhist altar room sits under a lower ridge, and beyond it a newer Zashiki wing continues westward. That drop is not a defect. It marks where an older core ends and a later reception wing begins, and it is the clearest evidence on the exterior that the Shirai Family Residence Main House grew in stages.
Visiting the Shirai Family Residence Main House
This is a private house. Toyokawa City lists the owner as a private individual, and there is no interior opening, no admission desk and no published visiting hours. What you can do is look at it from the road, which is where the building was always meant to be seen from.
The nearest station is Kō on the Meitetsu Nagoya Main Line, about 360 metres away, roughly 5 minutes on foot. Kō is served by all Meitetsu services below limited express and by some rapid limited express trains, and it is the junction for the Toyokawa Line, so reaching it from Nagoya or Toyohashi is straightforward.
Photography from the public road is unrestricted, and the north face catches good light in the afternoon. Please keep to the road, do not enter the grounds, and remember that people live here. For questions about interior openings, the Lifelong Learning Division of the Toyokawa Board of Education handles cultural property enquiries for the city.
