A Dyer's House That Moved House
Harikoshi-tei (はりこし亭, Harikoshitei) is a townhouse of 1868 standing at Otsu Aza Shiroshita 1208-7 and adjacent lots in Komoro City, Nagano Prefecture, relocated to its present site in 2002 and entered on Japan's national register of Tangible Cultural Properties on 18 October 2006. The Agency for Cultural Affairs records a building area of 356 square metres and lists the owner as Nakadana Onsen Co., Ltd.
The building did not begin here. Komoro City's account holds that it was raised beside the old Hokkoku Kaidō, the highway running north through the town, and that construction stretched over twelve years from the closing decade of the Edo period until completion in the first year of Meiji. The family who built it were indigo dyers. By the late twentieth century the house had deteriorated and was headed for demolition, until it was taken apart, carried to the grounds of the Nakadana Onsen inn and reassembled. It opened as a restaurant on New Year's Day 2002.
The plan runs nine ken along the ridge by seven and a half ken deep. A through-passage of packed earth and the kitchen occupy the south side; the raised floor fills the north, holding six rooms arranged in two ranks. That layout is textbook machiya: the earth-floored corridor was a working street pulled indoors, running from the front door to the back of the lot, and the rooms sat beside it in a line.
Two details on the outside are worth naming. The front carries a sode-udatsu, a short projecting fire wall at the upper level, and the ridge is raised into a koshiyane, a monitor roof that lifts smoke and heat out of the building. The current roof is sheet metal with tile in part; the Agency's record notes that the house was originally tiled throughout.
Timber Paid in Trees, and a Note on the Record
The best story attached to this house concerns its keyaki, the Japanese zelkova used lavishly through the interior. Komoro City relates that in the late Edo period the family supplied dyed goods to Komoro Castle and were paid not in coin but in standing timber from the castle grounds. Whatever the exact arrangement, the wood is there to be seen. A single continuous daikoku-bashira, the principal post, measures about 30 centimetres square. Zelkova was used for the agarikamachi, the step-up beam at the edge of the raised floor, and elsewhere.
Craft accumulates in the details. Adze marks remain on the beams at the upper level. In the inner reception room, a carved ranma transom in red zelkova shows a phoenix among paulownia flowers, and the nail covers are worked into cranes. The sliding-shutter box carries carved cranes and tortoises. The monitor roof over the ridge rises about eight metres.
One point requires care. The Agency for Cultural Affairs records the structure as single-storey timber construction and applies the first registration criterion, that the building contributes to the historic character of the national landscape. Komoro City's page describes it instead as two-storey and cites the third criterion, that the building would be difficult to reproduce. The national database is the authoritative source and its wording is followed here. The apparent contradiction between "single-storey" and a second-floor sode-udatsu is a familiar one in townhouse architecture, where a low upper level is often not counted as a full storey, though readers should treat the point as unresolved. Both sources agree on the registration date of 18 October 2006; the registration number is 20-0299, from the fifty-second round.
Komoro City also notes that the relocation project received the Komoro Machinami Prize, a local award for work contributing to the restoration and preservation of old houses.
The One You Can Actually Go Inside
Most registered properties of this kind are private homes viewed from the road. This one is a working restaurant, which means the interior is open to anyone willing to order lunch. That is an unusually direct way to experience a nineteenth-century house.
Harikoshi-tei operates as an annexe of Nakadana Onsen, the hot-spring inn associated with the writer Shimazaki Tōson, who taught in Komoro at the turn of the twentieth century. The restaurant takes its name from harikoshi manjū, a local buckwheat sweet that appears in his Chikumagawa no Suketchi. Buckwheat remains the centre of the menu: house-made soba, walnut soba among the standards, and seasonal vegetable dishes.
Lunch runs from 11:30 to 14:00 and takes walk-ins without a reservation. Evening service, 18:00 to 21:00, is a soba kaiseki course by advance booking only, from about 12,100 yen including tax and service. The restaurant closes on Wednesdays and on irregular additional days, so confirming by telephone is sensible before making a special trip. Photography of the interior is generally accepted as a matter of courtesy toward other diners rather than rule, so keep it discreet during service.
Once inside, look up and look down. Up, into the monitor roof, where the volume above the earth floor opens toward the ridge. Down, at the step where the packed earth meets the raised floor, and at the zelkova beam that marks that line. Then find the transom in the inner room.
The grounds sit at 1210 Otsu, Komoro, about twenty minutes on foot from JR Komoro Station or five by car, twenty-five minutes by car from Sakudaira Station on the Hokuriku Shinkansen, and fifteen from the Komoro interchange. Twenty free parking spaces are available. Note that the address registered with the Agency for Cultural Affairs uses the older lot numbering and differs from the inn's postal address. Kaikoen, the Komoro castle park, is within walking distance of the station.

Q&A
- Can I go inside Harikoshi-tei?
- Yes. Harikoshi-tei operates as a restaurant in the grounds of Nakadana Onsen, so the interior is accessible to diners. Lunch from 11:30 to 14:00 accepts walk-ins; the evening kaiseki course from 18:00 to 21:00 requires advance booking. It is closed on Wednesdays and on irregular additional days.
- How do I get to Harikoshi-tei from Komoro Station?
- The Nakadana Onsen grounds are at 1210 Otsu, Komoro City, about twenty minutes on foot from JR Komoro Station or five minutes by car. From Sakudaira Station on the Hokuriku Shinkansen it is about twenty-five minutes by car, and about fifteen minutes from the Komoro interchange. Twenty free parking spaces are available on site.
- Why was Harikoshi-tei moved, and where did it come from?
- According to Komoro City, the house stood beside the old Hokkoku Kaidō highway and belonged to a family of indigo dyers. Completed in 1868 after twelve years of building, it had fallen into disrepair and faced demolition, so it was dismantled, moved to the Nakadana Onsen grounds and reassembled, reopening as a restaurant on 1 January 2002. The relocation later received the Komoro Machinami Prize.
- What should I look at inside Harikoshi-tei?
- The zelkova, first of all: a principal post roughly 30 centimetres square runs the full height, and the same timber appears at the step-up beam. Adze marks survive on the upper beams. In the inner room a carved transom in red zelkova depicts a phoenix among paulownia flowers, with crane-shaped nail covers, and the shutter box outside carries cranes and tortoises. The monitor roof above the ridge stands about eight metres high.
- Is Harikoshi-tei a National Treasure or an Important Cultural Property?
- Neither. It is a Registered Tangible Cultural Property, registration number 20-0299, entered on 18 October 2006. Registration is a lighter system introduced in 1996 that encourages continued use of a building, which suits a case like this one where a relocated house earns its keep as a restaurant. National Treasure and Important Cultural Property are separate, more restrictive designations.
