A Late Edo Townhouse on the Kamiiso Road
The Kumagai Family Residence Main House (熊谷家住宅主屋, Kumagai-ke Jūtaku Shuoku) is a late Edo period merchant townhouse at 2-5-33 Chuo, Hokuto City, Hokkaido, entered on the national register of Tangible Cultural Properties on 27 March 2006. The Agency for Cultural Affairs dates the fabric to the closing decades of the Edo period, between about 1830 and 1867.
That date is the reason to pay attention. Hokkaido's building stock is overwhelmingly Meiji and later, because sustained Japanese settlement of the island is largely a post-1869 story. Buildings that predate the Meiji Restoration survive almost exclusively in Dōnan, the southern tip of the island around Hakodate, where Wajin communities had been established for centuries under the Matsumae domain. This house belongs to that older layer.
It stands in what was the town of Kamiiso until 2006, when Kamiiso merged with Ōno to form Hokuto City. The registration came through two months after the merger, so the property was registered under the new city name from the start.
The family it is named for made its money in agriculture and forestry. Kumagai Uhee is credited locally with laying the groundwork for both industries in the Kamiiso area, and he used the building as a shop and a home at the same time.
How the Plan Works
The house faces north onto the street, a frontage of seven ken with a depth of six, which works out to roughly thirteen metres by eleven. The registered specification gives it as timber-framed, two storeys, sheet-iron roofed, with a building area of 262 square metres. The roof is a simple gabled kirizuma form.
Inside, the plan splits along its length. The eastern side is doma, packed earth floor, running front to back. The western side is raised timber floor and is divided into the four-room grid called ta-no-ji shimadori, so named because the arrangement of partitions resembles the character 田. Above the mise, the shop room at the front, a second storey was built in. A single-storey wing, the sumiya, extends south from the doma.
One element was put back rather than preserved. Behind the degoshi, the projecting lattice screen across the ground-floor street front, a run of earth floor one ken deep was restored. The Agency's citation singles this out. Without that strip the building would read as an ordinary old house; with it, the commercial logic of a townhouse becomes legible again, because that is where customers stood.
The roof is the detail that marks the building as northern. Ceramic tile, the default for a townhouse of this rank on Honshu, is a liability in Hokkaido, where water gets into the tile and freezes and cracks it. Sheet iron went on instead. The registration criterion cited is that the building serves as a standard of design, and the Agency's note describes it as conveying the traditional townhouse form of the Dōnan region to the present day.
Seeing It
Be clear about this before you travel: the Kumagai Family Residence Main House is private property and is not open to the public. There is no interior tour, no admission desk, and no published opening hours. What you can do is look at it from the street, which is free and unrestricted, and read the explanatory board installed at the front.
From the pavement the composition is easy to read. The lattice screen runs across the ground floor. Above it the second-storey wall is white plaster. One window on the upper floor has been replaced with an aluminium sash at some point, and spotting that alteration is a useful exercise; registered properties are living buildings, and the register accommodates that.
Exterior photography from public land is fine. Do not photograph into the interior, and do not enter the plot. The building is somebody's home.
Access is straightforward. Kiyokawaguchi Station on the South Hokkaido Railway is about six minutes on foot. That line runs between Goryōkaku in Hakodate and Kikonai and is the successor to the old JR Esashi Line, so a visit fits neatly into a day out from Hakodate. Trains are infrequent, often one or two an hour, and checking the timetable before you set out saves a long wait.
Two other sites in Hokuto make sense on the same trip. The Matsumae Domain Hekirichi Jinya site, a bastioned earthwork fort of 1855 and a National Historic Site, lies inland and is known for its cherry avenue in spring. The Hokuto City Hometown Museum holds an overview display covering the city's national, prefectural and municipal cultural properties, including this house, which is useful given that the building itself cannot be entered.

Q&A
- Can I go inside the Kumagai Family Residence Main House?
- No. The Kumagai Family Residence Main House is a private residence and is not open to visitors. There is no admission fee and no interior access. The exterior can be viewed from the public street at any time, and an explanatory board stands at the front of the building.
- How old is the Kumagai Family Residence Main House?
- The Agency for Cultural Affairs dates it to the late Edo period, roughly 1830 to 1867. That places it before the Meiji Restoration, which is rare in Hokkaido. Pre-Meiji buildings survive mainly in the Dōnan region around Hakodate, where Wajin settlement long predates the general opening of the island.
- Why does the Kumagai Family Residence Main House have a sheet-iron roof instead of tiles?
- Ceramic tile performs poorly in the Hokkaido winter, since water absorbed by the tile freezes and splits it. Sheet iron sheds snow and tolerates the freeze-thaw cycle, and it became the standard roofing for the region. The registered specification records the roof as sheet iron.
- What was the Kumagai family's business?
- Kumagai Uhee is credited in local accounts with establishing the foundations of agriculture and forestry in the Kamiiso area, now part of Hokuto City. The building served as both his shop and his residence, which is the standard arrangement for a merchant townhouse of this period.
- How do I reach the Kumagai Family Residence Main House?
- The house is roughly six minutes on foot from Kiyokawaguchi Station on the South Hokkaido Railway, which links Goryōkaku in Hakodate with Kikonai. Services are infrequent, so check the timetable in advance. The address is 2-5-33 Chuo, Hokuto City.
