Mie Residence Main House

A Single-Storey House of 1931 in Wakita-machi

Mie Residence Main House (三重家住宅主屋, Mie-ke Jūtaku Shuoku, also written Mieke Jutaku Shuoku) is a single-storey timber dwelling built in 1931 at Wakita-machi in Kawagoe City, Saitama Prefecture, and entered on the national register of Tangible Cultural Properties on 19 December 2014. It occupies a building area of 156 square metres beneath a clay-tiled roof, and it is still a lived-in family home.

The roof announces the house before anything else does. Both the main roof and the smaller roof sheltering the entrance porch are built as irimoya, the hipped-and-gabled form in which a gable rides above a four-sided slope. What sets them apart is the curve. Instead of the concave sweep familiar from temple eaves, these roof planes carry a mukuri, a gentle convex swell that makes the tiles bulge outward by a few centimetres across their length. The effect is easy to miss and hard to unsee once noticed. Sunlight slides across a mukuri roof rather than pooling in it, and the silhouette softens instead of lifting at the corners.

That choice places the house in a particular tradition. Convex roofs belong to the sukiya line of Japanese building, the refined domestic manner descended from tea architecture, where restraint counts for more than display. A carpenter who shapes a mukuri is spending labour on something no passer-by is meant to remark upon.

Kawagoe had become Saitama Prefecture's first city in December 1922. Nine years later this house went up on a residential street that the Agency for Cultural Affairs identifies as part of the former samurai quarter of the castle town, a short walk from the railway that was pulling the town's centre of gravity southward.

Registered, Not Designated: What the 2014 Listing Means

The house carries registration number 11-0142 and came in with the seventy-ninth round of registrations. The criterion applied was the first of the three the system offers: contributing to the historic landscape of the nation. Its gate, registered on the same day as 11-0143, is treated as a separate property.

English-language writing about Japanese heritage tends to flatten every category into "cultural property," which obscures a real distinction. Registration (tōroku) and designation (shitei) are two different instruments. Designation as an Important Cultural Property or National Treasure is the stronger measure, applied to a small number of buildings and backed by tight controls on any alteration. Registration, introduced in 1996 for structures over fifty years old, works by notification rather than permission: owners tell the national government before making significant changes to the exterior, receive certain tax and repair benefits, and otherwise carry on living in the building. The system exists precisely for houses like this one, buildings whose value lies in ordinary continuity rather than exceptional rarity, and which would be lost by attrition if the only available protection were the strictest kind.

Inside, the plan explains the listing. Six rooms sit in two ranks of three, front and back, with corridors running around them. The principal zashiki, the formal reception room, is fitted with high-quality alcove furnishings and ceiled with a gō-tenjō: a coffered ceiling of timber battens laid in a grid, a treatment normally reserved for the most formal space in a building. In a private house it functions as a declaration of hierarchy. This is the room where guests were received.

The detail the Agency singles out is quieter. A corridor separates the entrance from the living rooms. In older Japanese houses, rooms opened directly into one another and a visitor stepping through the door was already inside the household's daily space. Separating the two with circulation was one of the central moves of the housing reform debates that ran through the Taishō and early Shōwa years, and it produced the plan type that would dominate Japanese middle-class building for the next half century. The Agency reads this house as a good example of that modern form. Kawagoe City records the owner as a private individual.

Seeing the House Without Going Inside

This is a private residence and it is not open to the public. There are no visiting hours, no admission fee, and no interior or garden access of any kind. What is available is the view from the public road, and that view is worth the detour if you are already walking Kawagoe.

From the street you get the roofline, the depth of the eaves, and the small gate on the eastern edge of the plot, which opens toward Hachiman-dōri, the street running parallel to the Crea Mall shopping arcade east of the station. The gate's flanking wing walls are finished with a slatted openwork transom above vertical boarding, and through that slot the garden in front of the house reads as a band of green. Copper sheeting on the gate roof has weathered to the dull green that copper reaches after several decades.

Please keep to the road. Do not step onto the drive, do not lean over the wall, and use a camera with the discretion you would want applied to your own front door. Photographing the street elevation is a normal thing to do in Japan; photographing into a household's garden or its residents is not.

Getting there is straightforward. The house stands roughly 400 metres north of the east exit of Kawagoe Station, served by the Tobu Tojo Line and the JR Kawagoe Line, which is about five minutes on foot. Honkawagoe Station on the Seibu Shinjuku Line lies some 700 metres to the northwest.

For an interior of the same period that you can actually enter, walk fifteen minutes north to the Former Yamazaki Family Villa (旧山崎家別邸) at Matsue-chō 2-7-8. Built in 1925 as the retirement house of the fifth-generation head of the Kameya confectionery, designed by the architect Yasuoka Katsuya, it was designated an Important Cultural Property in 2019 and is open to the public for 100 yen. Opening hours run 9:30 to 18:30 from April through September and 9:30 to 17:30 from October through March, with closures on the first and third Wednesday of each month and over the New Year period. Hours change, so check the city's page before you go.

Beyond that, Kawagoe's Ichiban-gai street of fire-resistant kurazukuri merchant houses is a twenty-five-minute walk north and forms a nationally selected preservation district. Kawagoe Hachiman-gū, the shrine that gives Hachiman-dōri its name, sits a few minutes south of the Mie house and is free to enter. Between them, the two make a useful frame for what the Mie Residence represents: not the spectacular Kawagoe of the tour buses, but the ordinary residential city that grew up alongside it.
