A House Designed by a Son for His Father
Kanazawa House Main Building (金澤家住宅主屋, also written Kanazawa-ke Jūtaku Shuoku) is a two-storey wooden residence at 2-2-7 Nishikata in Tokyo's Bunkyo Ward, completed in 1930 and entered on Japan's register of Tangible Cultural Properties on 11 December 1998. The Agency for Cultural Affairs lists a building footprint of 200 square metres and a roof laid partly in clay tile, partly in sheet metal.
The person who drew it was Yōji Kanazawa (金澤庸治, 1900–1982), an architect who taught in the architecture department of the Tokyo Fine Arts School, the institution that later became Tokyo University of the Arts. He did not design the house for a client. He designed it for his father.
That single fact shapes how the building reads from the street. There is no display frontage, no grand porte-cochère, none of the assertive Western detailing that wealthy Tokyo families were commissioning in the same decade. What stands behind the board fence is a careful, unhurried piece of domestic architecture by someone who expected to visit it for the rest of his life.
The construction contract went to Shimizu-gumi, the builder known today as Shimizu Corporation. In 1930 that was a considered choice rather than an obvious one, and it shows in how the timberwork has survived nearly a century of Tokyo weather.
Why the Register Took It In
Japan's registration system for cultural properties, launched in 1996, was created for buildings like this one: privately owned, still lived in, more than fifty years old, and worth keeping without freezing. Registration imposes lighter obligations than designation as an Important Cultural Property, which is precisely the point. Owners can continue to use, repair and adapt their houses.
The Kanazawa house was registered under the criterion covering buildings that serve as a model of design (造形の規範となっているもの), and carries registration number 13-0045. Two companion structures on the same plot went onto the register the same day: the small Western-style atelier (13-0046) and the gate with its attached board fence (13-0047). Bunkyo Ward, which counts sixty-five registered structures within its boundaries, notes that what the register protects in cases like this is the exterior as seen from the road.
Location carries part of the value. Nishikata was the mid-residence of the Abe family, lords of the Fukuyama domain, during the Edo period; after 1868 the family developed their own land as a residential quarter. Proximity to the Imperial University drew professors, novelists and researchers, and by the late Meiji period the neighbourhood had acquired the nickname gakusha-machi, the scholars' town. Nishikata is said to have come through both the 1923 earthquake and the 1945 firebombing largely intact, which is why houses of this age survive here when they have vanished from most of central Tokyo.
The Agency for Cultural Affairs describes Kanazawa as an assistant professor at the Tokyo Fine Arts School. Chronologies compiled by the university's architecture department place his promotion to that rank in 1936, six years after the house went up, and record him as a lecturer from the late 1920s. The discrepancy is worth noting rather than resolving.
What Rewards a Second Look
Stand on the lane outside and the roof tells you something. Among the structures on the plot, only the two-storey main house has its ridge turned to run east and west. Everything else follows a different axis. It is the kind of decision an architect makes on paper after walking the site several times, balancing the shape of the ground, the reach of winter sun into the rooms, and the way the roof planes will read from the approach.
The mixed roofing repays attention too. Clay tile and sheet metal appear on the same building, each assigned to the surfaces where it works best. Sheet metal handles shallow pitches and awkward junctions that tile cannot; tile carries the visual weight where the roof is seen. Neither material is decorative here.
The house is a private residence and is not open to visitors. There are no set opening hours, no admission charge and no interior access. Photography from the public lane is not restricted, but the property is someone's home, and the narrow residential streets of Nishikata are not a place for tripods or raised voices.
Getting there is easy. Todaimae Station on the Tokyo Metro Namboku Line sits about a seven-minute walk away; Hakusan Station on the Toei Mita Line is roughly twelve minutes. Anyone making the trip should also walk two blocks to 2-9-12 Nishikata, where the Hirano House stands. Its main building, Western wing, brick storehouse, tea room and two gates, all designed by Katsuya Yasuoka around 1921 and 1922, were registered in September 1998, three months before the Kanazawa buildings. Together the two properties give a compact picture of how Tokyo's professional class housed itself between the wars.
