A country doctor's building of 1927 at Ouma
The Former Imaizumi Clinic Medical Building (旧今泉医院診療棟, Kyū Imaizumi Iin Shinryōtō) is a wooden clinic building of 1927 at Ouma Nishi in Mitsucho, Toyokawa City, Aichi Prefecture, added to the national register as a Registered Tangible Cultural Property on 2 March 2004. It is a single story structure with a partial 2nd floor, roofed in tile, with a building area of 221 square meters.
It stands at the western edge of its plot and faces west. Ouma is an old settlement of narrow lanes a short distance inland from Mikawa Bay, and the houses along the lane are the ordinary timber houses of rural Aichi. The Former Imaizumi Clinic Medical Building is the one facade on the street that was designed in a Western manner, and its eaves sit noticeably higher than those of its neighbours.
Two other registered structures share the plot. A ward building touches the northeast corner of the clinic, and a small concrete hand washing station sits in the front garden. All three were registered on the same day under separate registration numbers. This article covers the clinic building itself.
Why it was registered
Registration is the lighter of the two systems Japan applies to architectural heritage. Rather than freezing a building in place, it asks the owner to keep the exterior intact while continuing to own the property and live with it. The Former Imaizumi Clinic Medical Building was registered under the criterion covering buildings that serve as a model of design, and carries registration number 23-0130. The public notice followed on 29 March 2004.
The Agency for Cultural Affairs describes the building as a good example of hospital architecture that took up Western design. Its category in the national database is welfare and culture, in the sub-class of buildings.
That description carries more weight once you know what rural practice looked like when this compound went up. A country doctor usually worked out of a house that was indistinguishable from his neighbours' houses. Here the owner spent his money on the one wall that patients saw first, and left the rest of the compound in the local idiom. The result is a building that shows how a new profession advertised itself in a village.
What to look for from the street
Everything worth studying is on the west front. The elevation is symmetrical, and only the central bay rises to two floors while the wings stay low. Raising the middle was a standard way of lending dignity to a small building, and the same trick appears on schools and town halls of the period.
A Western style porte cochere projects from the centre of that front. Stand under it and look up: a framed board bearing the clinic's name is fixed above the opening. Sign and structure were built as one piece, placed where every arriving patient had to pass.
The roof tells a different story. It is Yosemune-zukuri, hipped on all four sides, and covered in Sangawara-buki pantiles, both entirely conventional Japanese work. The walls are finished in what Japanese builders call German wall, a mortar surface worked to a deliberately coarse texture. Morning and late afternoon light rakes across it and brings out the grain; under a flat grey sky the same wall reads as plain render.
Look past the right hand end of the facade and a low tiled roof comes into view behind it. That is the ward building, joined to the rear corner. The contrast between a Western face and a Japanese back is visible from the road without entering the plot.
Visiting
The Former Imaizumi Clinic Medical Building is privately owned and the interior is closed. Toyokawa City lists the owner of all three registered structures here as a private individual. No regular opening and no special opening had been announced as of August 2026.
Viewing means looking at the exterior from the public lane. The garden inside the gate is private ground and visitors may not enter. Because the main front faces the street, the porte cochere, the name board and the texture of the walls are all readable from where you can legally stand.
Photography of the exterior from the road is not restricted. People live on the plot, so setting up a tripod for a long session or pointing a lens through the gate is out of place. The lane is narrow, and a parked car blocks it completely.
The nearest station is Aichi-Mito on the JR Tokaido Main Line, about 700 metres away, a walk of roughly ten minutes. Head south from the station, turn into the village lanes and watch the west side of the road. There is no visitor parking.

Q&A
- Can you visit the Former Imaizumi Clinic Medical Building, and can you go inside?
- The interior is closed. The building is privately owned and the grounds are not open, so a visit means viewing the exterior from the public lane. The main front faces the street, so the porte cochere, the name board and the wall finish are all clearly visible from outside the gate.
- How do you get to the Former Imaizumi Clinic Medical Building from the nearest station?
- Take the JR Tokaido Main Line to Aichi-Mito Station, then walk about 700 metres south, roughly ten minutes. The address is 37 Ouma Nishi, Mitsucho, Toyokawa City, Aichi Prefecture. There is no visitor parking and the lanes are narrow, so arriving by train is easier.
- Is photography allowed at the Former Imaizumi Clinic Medical Building?
- Photographing the exterior from the public road is not restricted. The plot is occupied, so avoid long tripod sessions and do not shoot through the gate into the private garden. Keep clear of the lane itself, which is too narrow for people to pass a stationary photographer easily.
- When was the Former Imaizumi Clinic Medical Building built and registered?
- It was built in 1927. Registration as a Registered Tangible Cultural Property took effect on 2 March 2004, with the public notice on 29 March of the same year, under registration number 23-0130. The criterion applied was the one for buildings that serve as a model of design.
- How does the clinic relate to the Imaizumi ward building and hand washing station?
- All three stand on one plot and were registered on the same day under separate numbers. The ward building is a Japanese style single story block attached to the northeast corner of the clinic, and the hand washing station is a small concrete fixture in the front garden. One medical practice is therefore recorded as three separate cultural properties.
