A Merchant House Facing the Old Port Road
The Ochi Family Residence Shop and Dwelling (越智家住宅店舗及び居宅, Ochi-ke Jūtaku Tenpo oyobi Kyotaku, also written Ochike Jutaku) is a late Edo period merchant house in the Nyūgawa district of Saijō City, Ehime Prefecture, added to the national register of Tangible Cultural Properties on 14 February 2002. The Agency for Cultural Affairs places its construction between 1830 and 1867, the closing decades of Tokugawa rule, and records it as a single timber building of two storeys with a tiled roof and a footprint of 346 square metres.
The house faces north onto the arterial road that runs through the middle of town, the road once known locally as Hongawara-dōri. That orientation is not accidental. Nyūgawa sat on the Hiuchi-nada coast of the Inland Sea, and boats could once come up the Ōmagari River almost to the door. Goods moved from the harbour along this street, and the merchants who handled them built their shopfronts to face it.
The Ochi family traded under the shop name Masuya. In the Meiji era they dealt in mokurō, the pale vegetable wax pressed from sumac berries that Ehime exported in quantity. Later they switched to fertiliser and agricultural chemicals bought in Osaka and sold across the Shūsō plain, and by the early twentieth century they were spoken of as the wealthiest merchants in the district.
Why the Building Was Registered
Japan runs two parallel systems for architectural heritage. Important Cultural Properties and National Treasures are designated, which brings tight controls and substantial state involvement. Registered Tangible Cultural Properties, a category created in 1996, work differently: owners notify the authorities before altering the exterior, and in exchange they keep the building in ordinary use. Most registered properties are privately owned houses, shops and workshops that would otherwise vanish quietly.
The Ochi shop and dwelling was registered under the criterion of contributing to the historic landscape of the country, registration number 38-0020, in the thirty-second round of registrations. The notice was published on 12 March 2002. The Agency's assessment calls it a representative merchant house of the Iyo region and an element the streetscape cannot do without.
Two more buildings on the same property were registered on the same day: the Sukiya (38-0021), a retirement house of 1927, and the Tea House (38-0022) of the same year. The three together show how one merchant family built and rebuilt across a century.
Reading the Facade
The plan follows what specialists call omoteya-zukuri, an arrangement borrowed from Kyoto and Osaka in which the shop block and the living block are built separately and then joined. Here the front shop is a two-storey kirizuma gable structure with an unusually high eaves line, softened by a geya pent roof over the entrance. Behind it the living quarters drop to a single storey.
Look at the materials. The roof is laid in hongawara, the heavy pairing of broad flat pan tiles and semi-cylindrical cover tiles that signals expense. The gable ends are finished in white lime plaster. The side walls are clad in vertical boarding. That combination, formal plaster where the street sees it and plain timber where it does not, is a good short lesson in how merchant houses managed display.
Inside, though the rooms are not accessible to visitors, published surveys describe a tōri-doma: an earth-floored corridor running the depth of the shop, with the chōba accounting space opening off it and a dark, polished daikokubashira pillar carrying the frame. Deeper in the house is a reception room finished in Western style, an anomaly against the timber and paper elsewhere and a common gesture among prosperous late-Meiji and Taishō merchants. The south end held the family rooms, the kitchen, the washing area and quarters for employees. Roughly ten people, family and staff together, once lived under this roof.
Visiting Nyūgawa
The interior of the Ochi Family Residence is not open to the public as a rule. Ehime Prefecture's official tourism service lists it as closed inside, and the property remains in private hands. What you can do is stand on the street and read the front, which is where the registration criterion points anyway: this building was listed for what it contributes to the townscape.
Getting there is straightforward. JR Nyūgawa Station on the Yosan Line is about 800 metres south, a walk of roughly ten minutes; limited express services stop here. By car, the house sits just off National Route 196 between Imabari and Saijō. Photography from the public road is unproblematic, but the building is someone's property and the neighbours are living their lives, so keep lenses out of gateways.
If you want a fuller afternoon, the Saijō City Toyo Local Museum lies about 1.1 kilometres to the southwest, admission free, closed Mondays. Its displays cover the history of the old Toyo area, including the horseshoe crabs of the Hiuchi-nada shallows. Walking between the two takes you through the streets the Ochi family's fertiliser carts once used.

Q&A
- Can visitors go inside the Ochi Family Residence Shop and Dwelling?
- No. The interior is listed as closed to the public by Ehime Prefecture's tourism service, and the house is privately owned. The exterior can be viewed freely from the public road in front of it.
- When was the Ochi Family Residence Shop and Dwelling built, and when was it registered?
- The Agency for Cultural Affairs dates construction to the late Edo period, between 1830 and 1867. Registration took effect on 14 February 2002, with public notice on 12 March 2002, under registration number 38-0020.

- Walk north from JR Nyūgawa Station on the Yosan Line for about ten minutes, roughly 800 metres. Drivers will find the house immediately off National Route 196 in central Nyūgawa, Saijō City.
- What does the designation Registered Tangible Cultural Property mean for the Ochi Family Residence Shop and Dwelling?
- Registration is a lighter form of protection than designation as an Important Cultural Property. The owner notifies the authorities before altering the exterior and may otherwise continue to use the building normally. The system began in 1996 and covers many privately held houses and shops.
- Are there other registered buildings on the Ochi Family Residence site?
- Yes. The Sukiya retirement house (38-0021) and the Tea House named Shōin (38-0022), both completed in 1927, occupy the same long north-south plot and were registered on the same date. All three stand behind or beside the shop block and are likewise closed to visitors.
