A House Assembled Out of a School
Kawahara-ke Jutaku Shuoku (河原家住宅主屋, also written Kawahara-ke Jūtaku Shuoku, "main house of the Kawahara Residence") is a single-storey timber dwelling with a rooftop tower at Minami-Magome, Ota Ward, Tokyo, entered on Japan's national register of tangible cultural properties on 15 February 2000 and gazetted on 2 March that year. Almost every part of it came from somewhere else, and specifically from a school.
The Agency for Cultural Affairs records the entrance and classroom sections of the former Magome Elementary School, built in 1885, as having been dismantled and re-erected here and converted into a Japanese-style residence. Then, in 1963, when the school replaced the building that had succeeded that first one, the family acquired its clock tower, put up in 1925, and set it on the roof above the study.
So the house has two ages inside one address. Ordinary house frames in Japan are joined by mortise and tenon and pinned with wooden wedges, which means a building can be taken apart, carted off and put back up. The practice has a name, ichiku, and it has moved teahouses, gate structures and farmhouses across Japan for centuries. What is unusual here is not the method but the source: a public elementary school, converted into someone's home, twice over.
The Clock That Belonged to Everyone
Between 1925 and about 1962 the clock tower stood on the school and functioned as a landmark for the neighbourhood. Children checked it on the way in. Adults passing on the road below took the time from it. When the school was rebuilt in 1963 the tower could have gone to a scrap yard. Instead it crossed a few streets and came to rest on a private roof, where it remains.
That is the reason for the registration criterion applied here: a building that contributes to the historic landscape of the nation. The register number is 13-0070, from the 22nd round, which places this among the earlier registrations in Tokyo. The framing works: what is being protected is less an architectural specimen than a piece of shared local memory that happens to sit on top of a house.
The recorded specification is timber frame, single storey with rooftop tower, tiled roof, building area 123 square metres. One caution about dates. The Agency's year field reads Taisho 14, that is 1925, while its own description makes clear the principal fabric came from the 1885 school and the 1925 element is the tower. Readers who need a precise construction chronology should treat the single year in the database as a register convention rather than a building date, and consult Ota Ward directly.
The wider setting deserves a mention. Minami-Magome lies within the district known as Magome Bunshimura, the writers' village, where novelists, poets and artists settled in numbers after the 1923 Great Kanto Earthquake pushed people out of central Tokyo. The area kept its low, green, residential character while the city changed around it, and the survival of an oddity like this house is part of the same story.
Going to Look
The address is 1-55-8 Minami-Magome, Ota Ward. Nishi-Magome Station, the western terminus of the Toei Asakusa Line, is about eight minutes on foot from the west exit. That line runs through Nihombashi and Asakusa, so the trip from the older tourist districts of Tokyo takes half an hour and needs no transfer.
This is a private residence and the interior is closed. The Agency's database lists no owner name, which in its conventions indicates private ownership, and no ward-run opening programme exists. What you can do is walk the street and look up. The tower is the object worth the journey: a small timber turret sitting on the roof of a low Japanese house, in a proportion that no architect designing from scratch would have arrived at.
Approach on foot rather than by car, since the streets here are narrow and residential. Keep to the public road, do not linger at the gate, and photograph the roofline rather than the windows. People live in this building, which is exactly the condition the registration system was built to accommodate: protection light enough that a hundred-year-old structure can go on being a home.
If you want to make an afternoon of it, several other registered properties stand within walking distance in Magome and Sannō, among them the Ryūshi Memorial Museum with the painter's former residence and studio, and Sannō Sōdō Memorial Hall, which preserves part of the writer Tokutomi Sohō's house. Both admit visitors and both fill in the district's history in ways a closed private house cannot.

Q&A
- Can I go inside Kawahara-ke Jutaku Shuoku?
- No. It is a private house and the interior is closed to the public. Ota Ward runs no opening programme for it. Viewing is limited to the exterior from the public road, where the rooftop clock tower is clearly visible.
- How do I get to Kawahara-ke Jutaku Shuoku?
- The address is 1-55-8 Minami-Magome, Ota Ward, Tokyo. From the west exit of Nishi-Magome Station on the Toei Asakusa Line it is roughly eight minutes on foot. The Asakusa Line connects directly to Nihombashi and Asakusa without a transfer.
- Where did the clock tower on Kawahara-ke Jutaku Shuoku come from?
- From Magome Elementary School. The tower was built in 1925 on the school's newer building and served as a neighbourhood landmark until about 1962. When the school was rebuilt in 1963 the tower was relocated here and mounted above the study.
- Why was Kawahara-ke Jutaku Shuoku registered as a cultural property?
- Under the criterion of contributing to the historic landscape of the nation. The house is composed largely of relocated parts of a Meiji-period school, topped by that school's later clock tower, and it has long been a familiar sight in the neighbourhood. Registration took effect on 15 February 2000.
- What else is worth seeing near Kawahara-ke Jutaku Shuoku?
- The surrounding district is Magome Bunshimura, where writers and artists settled after the 1923 earthquake. Within walking distance are the Ryūshi Memorial Museum, with the painter Kawabata Ryūshi's former house and studio, and Sannō Sōdō Memorial Hall, which preserves part of Tokutomi Sohō's residence. Both are open to visitors.
