An Annex Joined at an Angle
Kappo Tochu Bekkan (割烹東忠別館, also romanized Kappō Tōchū Bekkan), the annex of the Tochu restaurant in Motomachi, Ojiya City, Niigata Prefecture, is a two-storey wooden building of the early Showa period that was listed as a Registered Tangible Cultural Property of Japan on 17 November 2015.
The Agency for Cultural Affairs assigns it to the years 1926 to 1945. Its footprint is 107 square metres, roughly half that of the main building it adjoins, and it carries a tile roof where its two registered neighbours on the site are covered in sheet steel.
The detail that shapes everything else about the building is its junction with the main house. The two do not meet squarely. The plot forced a diagonal connection, and the floor levels do not line up either, so the passage between them works as a skip-floor: you move across and half a storey at the same time. Nobody designing on open ground would arrange a restaurant this way.
The result is a building you read in fragments. There is no vantage point from which the whole interior resolves into a plan. Turn a corner and the ceiling height changes; climb four steps and the garden appears at a different angle. The official citation describes the effect as a spatial composition full of variation, which is the polite technical version of saying the building keeps surprising you.
Why the Annex Was Registered
Registration number 15-0421 was gazetted on 17 November 2015 in the 82nd round of national registrations, alongside the main building and the storehouse. The applicable criterion was the same for all three: that the structure contributes to the historical landscape of the country.
What the citation singles out in the annex is quality of finish rather than age or rarity. The zashiki-kazari, the built-in furnishings of a formal Japanese room, are described as large in scale and refined in design at the same time. That combination is harder to achieve than it sounds. A generously proportioned tokonoma alcove with heavy timber can easily read as ostentatious; the assessment here is that it does not.
The dating matters for understanding why. Prewar Showa, the late 1920s and the 1930s, was a productive period for high-end Japanese restaurant architecture. Carpenters trained in the sukiya tradition of the tea house were still working in numbers, materials could be sourced without wartime restriction, and provincial merchants had money to spend on entertaining. Ojiya's money came from ramie crepe weaving and from ornamental carp breeding, both trades that ran on face-to-face negotiation.
Buildings of this class were built in quantity across Japan and then lost in quantity. Air raids took some, postwar redevelopment took more, and the decline of the formal banquet economy from the 1990s onward removed the business case for maintaining the rest. The Ojiya annex survives because it is still in use and because ownership passed to a public-interest foundation, the Ojiya City Industrial Development Center.
Rooms, Verandas and the Garden Edge
The plan is straightforward once you are inside a room. The ground floor holds two halls. The upper floor is given over to a single large hall.
Both levels open toward the garden, with a veranda running around the garden face and openings kept deliberately wide. The intention is legible: the room is meant to be occupied with the screens pushed back, so that the boundary between the mats and the pond garden becomes a line you can sit on rather than a wall you look through. Ojiya winters bury this landscape in snow, which means the same room delivers two entirely different experiences depending on the month you book.
Look up at the ceilings and along the alcove posts. The timber selection is where the money went, and the grain on a good tokobashira repays a minute of attention that most diners never give it.
Practical matters. The annex is part of a working restaurant, so it is entered as a dining guest rather than a visitor, and the restaurant does not publish which of its named rooms sit in which registered building. Booking by telephone (0258-82-2033) is the recommended route, and staff assign rooms according to party size, so a group hoping for a particular space should say so when reserving. Lunch runs 11:00 to 14:00 with arrival requested by 13:30; dinner 17:00 to 22:00 with arrival by 19:00. Closing days are irregular and listed month by month on the official website.
Getting there takes about five minutes by taxi from JR Ojiya Station on the Joetsu Line, or roughly a 20-minute walk. Drivers should allow about eight minutes from the Ojiya interchange on the Kan-etsu Expressway and consult the approach map the restaurant publishes, since the surrounding lanes are narrow. Four car parks around the site take about 18 vehicles between them. A free shuttle is offered for larger groups, by arrangement. Photography is best cleared with staff at reception, since other parties are dining nearby.

Q&A
- What makes Kappo Tochu Bekkan architecturally distinctive?
- The annex joins the main building at a diagonal because of the shape of the plot, and the two are linked by a skip-floor arrangement in which the connecting route changes level as it crosses. The Agency for Cultural Affairs cites the resulting variation in spatial composition, together with alcove furnishings that are both large in scale and refined in design.
- When was Kappo Tochu Bekkan built, and when was it registered?
- It dates from the early Showa period, recorded as 1926 to 1945, which makes it the middle building of the three in age. It was gazetted as a Registered Tangible Cultural Property (Structures) on 17 November 2015 under registration number 15-0421, in the 82nd round of registrations.
- Can visitors go inside Kappo Tochu Bekkan?
- Yes, as a dining guest of the restaurant Tochu Ojiya. Telephone reservation on 0258-82-2033 is recommended, including for lunch, because rooms are assigned by staff according to party size and purpose. The restaurant does not publish a floor plan showing which named rooms fall within the annex, so anyone hoping for a specific space should raise it when booking.
- How large is Kappo Tochu Bekkan and how is it built?
- It is a single wooden building of two storeys with a tile roof and a building area of 107 square metres. The ground floor contains two halls and the upper floor a single large hall, with a veranda along the garden face and wide openings toward the garden.
- How do you reach Kappo Tochu Bekkan from Ojiya Station?
- A taxi from JR Ojiya Station takes about five minutes and the walk about 20 minutes. By car it is roughly eight minutes from the Ojiya interchange of the Kan-etsu Expressway. Four car parks on site hold about 18 vehicles, and a free shuttle can be arranged for larger groups.
