A Late Edo Farmhouse in the Hills of Oguni
The Ohashi Family Main House (大橋家住宅主屋, Ōhashi-ke Jūtaku Shuoku) is a late Edo period farmhouse in the hamlet of Hossue, Oguni district, Nagaoka City, Niigata Prefecture, entered on the national register of Tangible Cultural Properties on 25 July 2011. It measures roughly 13 metres along its length and 8.2 metres across, giving a building area of 154 square metres, and it stands on sloping ground in a basin drained by the Shibumi River, ringed by ridges that rise to between 300 and 500 metres.
The roof is the first thing that registers from the lane below. It is a hipped thatch roof, yosemune-zukuri, its four faces meeting in a short ridge rather than the sharp gable of a Gassho house further south. Thatch on this scale is costly to keep, and the straw currently carries a temporary sheet-metal covering, a compromise seen on many surviving farmhouses across Niigata's snow belt. The metal hides the texture of the reed but preserves the shape, and the silhouette against the hillside is unchanged.
Along the front runs a geya, a lower lean-to roof that widens the shelter at ground level and keeps snow from piling against the wall. A small gabled porch breaks the line at the entrance. On one flank a stable, the umaya, is built directly onto the house, so that the horse wintered under the same roof as the family.
The Agency for Cultural Affairs dates the fabric to the late Edo period, with alterations around 1955, further work in the later Showa era, and a repair campaign in 2005.
Why the House Was Registered
Registration was granted under the criterion "a model of design", which in practice recognises a building that shows a regional type clearly and well. What the assessors singled out was the plan.
Step through the entrance and, in the original arrangement, you would have stood in the niwa, a packed-earth working floor that ran into the house rather than stopping at a threshold. Beyond it lay the daidoko, the kitchen and family living space. To the right, four rooms were laid out in the arrangement local carpenters called yomadori, a four-room grid that includes the dei, the formal room kept for guests and ceremonies, and the nema, the sleeping room. That sequence, earth floor to hearth room to formal room, is the ordinary grammar of a farmhouse in this part of Niigata, and the Ohashi house holds it intact.
What "registered" means here
Registered Tangible Cultural Property is a lighter category than Important Cultural Property. Introduced in 1996, it covers buildings generally more than fifty years old and asks the owner to notify the authorities before major changes rather than to seek permission. The system was designed for exactly this situation: a working building, still lived in, that would be poorly served by the restrictions attached to full designation. The register number for this house is 15-0334, granted in the seventieth round of registrations.
Seeing the House, and the Hamlet Around It
This is a private home. There is no ticket office, no opening time, and no interior access. Visitors should look from the public lane and go no further; the plan described above is known from the survey record, not from a tour.
That limitation matters less than it might sound, because the setting carries much of the interest. Hossue sits high in the folds of the Oguni hills, in one of the snowiest inhabited regions on earth. Winter accumulations here are measured in metres, and the low pent roofs, the deep eaves and the compact footprint of the house are all answers to that fact.
The hamlet has a harder recent history. When the Chuetsu Earthquake struck in October 2004, road damage cut Hossue off, and every household in the settlement was evacuated. Recovery work in the years that followed included rebuilding community facilities across the Oguni district. The Ohashi house came onto the national register in 2011, seven years after the shaking.
Getting there needs a car. Oguni has no railway; the nearest stations are Tsukayama on the Shinetsu Main Line and Ojiya on the Joetsu Line, each roughly ten to fifteen minutes by road from the district centre, with Nagaoka Station about forty minutes away. Hossue lies further up into the hills from that centre along narrow roads that are difficult from December through March. Late spring, when the snow has gone and the terraced paddies are flooded, is the easiest time to come.
Photography from the public road is not restricted, but this is someone's house. Keep to the lane, keep the noise down, and do not photograph people or into windows.

Q&A
- Can you go inside the Ohashi Family Main House?
- No. The Ohashi Family Main House is a privately owned residence and is not open to the public. The exterior can be seen from the public road, and visitors are asked not to enter the grounds.
- Where exactly is the Ohashi Family Main House?
- It stands at Yachi 681, Hossue, Oguni-machi, Nagaoka City, Niigata Prefecture, in a mountain hamlet in the former town of Oguni, which merged into Nagaoka City in 2005.
- When was the Ohashi Family Main House registered, and under what category?
- It was registered on 25 July 2011 as a Registered Tangible Cultural Property (building), register number 15-0334, under the criterion recognising a building as a model of design.
- How do you reach the Ohashi Family Main House by public transport?
- There is no practical public route to Hossue itself. Buses run from Nagaoka, Tsukayama and Ojiya stations only as far as the Oguni district centre, so a rental car or taxi is needed for the last stretch into the hills.
- Is the roof of the Ohashi Family Main House still thatched?
- The structure is a thatched hipped roof, but the thatch is presently protected by a temporary sheet-metal covering, recorded in the national database as kaya-buki (teppan kari-buki). The underlying form and framing remain those of a thatched roof.
- What is the best season to visit the area around the Ohashi Family Main House?
- Late spring through autumn. Oguni receives very heavy snowfall, and mountain roads to hamlets such as Hossue can be hard going from December into March.
