The timber house behind the storehouses
Sakacho Honten Main House is a 2-storey timber merchant residence in Chuo-cho, Koga City, Ibaraki Prefecture, built in the early Meiji period and listed on 26 September 2000 as a national Registered Tangible Cultural Property.
Five thick-walled storehouses share the plot with it. Sakacho Honten Main House is the one building here made in ordinary wooden construction, and it is where the family actually lived and received callers. The Agency for Cultural Affairs records a footprint of 135 square meters under a tiled roof.
The business behind it began in the early Edo period, when Sato Yaichizaemon settled in Daiku-cho, the carpenters' quarter of the castle town of Koga, and opened as a money changer. The shop traded under the name Sakacho. By the 9th generation it had moved into the wholesale sake trade, and it was still in that line when the buildings were registered.
Dating rests on the national record. The Agency places construction in the early Meiji period, giving a range of 1868 to 1911, and reads the house as a rebuilding carried out when the shop and side storehouses were being moved onto the site and the whole compound was reorganised.
Why it was registered, and what the reception rooms show
Sakacho Honten Main House was entered under the criterion for buildings that set a standard of form, with the registration number 08-0031. The official commentary is unusually specific about where the quality lies: not in the structure but in the joinery and design of the zashikikazari, the fittings of the formal reception room.
Zashikikazari is a collective term for the elements that mark the rank of a Zashiki: the Tokonoma alcove, the Tsukeshoin writing bay set into the window wall, and the staggered display shelves beside them. These were the parts of a merchant house a client saw, and the parts a family spent money on. Reading the commentary against the building tells you what the Sato household wanted a visitor to notice.
That emphasis also explains why the house belongs in the same registration as the storehouses rather than standing apart from them. The five storehouses were built for keeping things safe. Sakacho Honten Main House was built for being seen, and the group is only legible when both purposes are present.
Moving deeper into the compound
The approach matters. From the old Daiku-cho street you pass the shop storehouse first, then the side storehouse on the corner, and only after that does the roof of Sakacho Honten Main House come into view behind them. Merchant compounds in castle towns were laid out this way on purpose, with trade at the street and household life set back from it.
Inside, the timber is worth slowing down for. Look along the Nageshi tie-beams where they meet the posts, at the Ranma transoms over the sliding doors, and up at the ceiling boards. The interior has been adapted for public use, so not every surface is original, but the framing and the principal rooms carry the character the registration was granted for.
Then step back outside and look at the two roofs together. The plastered storehouses are squat and shut; the house is broader, lower-eaved and full of openings. Two ways of building, one household, about a generation apart.
How the house is used now, and visiting
Sakacho Honten Main House is the busiest building on the site. The ground floor holds a café, open 11 a.m. to 8 p.m. with last orders at 7 p.m., closed on Tuesdays and on the 2nd and 4th Wednesdays. The upper floor is given over to a shared workspace and to rental rooms of 10 and 6 Tatami mats, hired out for classes and small meetings.
The wider Koga no Oyasumidokoro Sakacho complex opens 9 a.m. to 5 p.m. and closes over the New Year period. There is no admission charge for the site. The main telephone is 0280-22-2781.
From JR Koga Station on the Utsunomiya Line the walk takes about 9 minutes. By car, allow roughly 30 minutes from the Kuki or Tatebayashi interchanges on the Tohoku Expressway, or about 35 minutes from Sakai-Koga on the Ken-O Expressway. Three car parks may be used: the Sakacho car park, Chuo-cho Hiroba and the Koga Literature Museum.
Rooms upstairs are frequently booked, so the upper floor is not always open to look at. No photography rule is published; the exterior can be photographed freely from the street, and for interiors it is best to ask at the counter.
