The building that faced the street
The Former Otsuka Sake Brewery Shop and Main House (旧大塚酒造店舗兼主屋, Kyū Ōtsuka Shuzō Tenpo-ken-Shuoku) is a 2-story wooden building of the middle Meiji era at 3351-2 Iwai in Bando City, Ibaraki Prefecture, put on the national register as a Registered Tangible Cultural Property on May 2, 2017 (Heisei 29). The Agency for Cultural Affairs dates it to the years 1883 to 1897, and the operators of the site place it before 1897 (Meiji 30).
It stands at the northwest corner of a brewing yard, which is the part of such a yard that the town actually saw. Behind it the work was done in warehouses. Here, at the front, sake was sold across a counter and the family lived. The two functions shared one roof, which is what the name records: tenpo, the shop, and shuoku, the main house.
The brewers here were the Aizawa family, established in the late Edo period, who ran the yard until 1931 (Shōwa 6). Otsuka Eikichi, a sake merchant from Noda in Chiba Prefecture, then took over the ground and the plant and traded as Otsuka Shuzō until 2011 (Heisei 23). Iwai was a market town on the road network of the old Sashima district, and a brewer's shop front was one of the places where that traffic stopped.
A modern plan behind an old face
The Former Otsuka Sake Brewery Shop and Main House measures 15 meters along the front and 10 meters deep, with a building area of 176 square meters. The roof is Yosemune-zukuri, hipped on all sides, and laid with Sangawara-buki pantiles.
Its plan begins from the standard rural formula, the regular four-room grid, and then departs from it in two places. The kitchen is pushed out beyond the line of the wall at the southeast corner instead of sitting inside the grid, and a corridor runs along the back of the Zashiki. Neither move belongs to an older farmhouse. Both belong to the Meiji era, when a merchant household wanted circulation that did not force visitors through the family's rooms.
That combination is the reason for the registration. The building was accepted under the criterion for buildings that contribute to the historic landscape of Japan, and it carries the status of Registered Tangible Cultural Property number 08-0297, counted as 1 building. Registered Tangible Cultural Property status was created in 1996 (Heisei 8) as a lighter alternative to designation, and it fits a building like this one, which earns its place through the ordinary streetscape it belongs to rather than through rarity.
Vat lids underfoot, a stair you climb through furniture
The ground floor of the Former Otsuka Sake Brewery Shop and Main House held an earth-floored Doma, a reception room, tatami rooms, a kitchen and a bath. A stair chest, a run of drawers built into the staircase itself, led up to 2 tatami rooms on the upper floor.
Ceilings are 3 meters high, which is generous for a house of this date and immediately noticeable on entering. Above the better rooms is a Gō-tenjō, its grid framed in the manner of tatami edging; elsewhere the flatter Saobuchi-tenjō is used. The transoms are Ranma cut in openwork, and the light through them changes through the day.
Look down, though, and the floor is the surprise. When the building was repaired in 2016 (Heisei 28), it was jacked up bodily, a new sill and foundation were laid beneath it, and it was lowered back into place. The new floorboards were cut from the lids of the brewery's sake vats. Walking across them gives a fairly direct sense of how wide those vats were.
One more thing repays a look. The rest wing, the part marked by a small chimney, carries a roof frame that carpenters find odd: the rising beams are staggered one above the other into the struts, in the manner of a Yojirō truss, but the upper beams are carried straight across the bays and no balance beam is used. The brick chimney just south of the Former Otsuka Sake Brewery Shop and Main House, standing where the kitchen chimney once did, is not part of the registered property, but the bricks are thought to come from the Kosuge prison brickworks in Tokyo; on the wall side, a stamp resembling a double-petalled cherry blossom can still be picked out.
Visiting the Former Otsuka Sake Brewery Shop and Main House
The building is in daily use and open to visitors. It works as the information center of the Bando City Tourism Exchange Center Shūroku (坂東市観光交流センター「秀緑」), which opened in November 2016 on the old brewery site and took its name from the house label. Admission is free. Opening is 10:00 a.m. to 6:00 p.m., and the site closes on Mondays, or the following day when a Monday falls on a public holiday.
Because the Former Otsuka Sake Brewery Shop and Main House is the reception building, it is the easiest part of the site to see at any hour it is open, and staff there answer questions and take bookings for the hall in the storehouse behind. Exhibitions of local ceramics and woodwork are sometimes hung in its rooms. No rule on photography has been published; ask at the desk if an exhibition is in place. Telephone 0297-35-0002 for the day's situation.
Getting here means a bus for most visitors. The stop to aim for is Honchō, 1 minute away on foot; buses run to it from Moriya Station on the Tsukuba Express, roughly 40 minutes on the Kantō Railway service toward Iwai Bus Terminal, and from Noda-shi Station on the Tōbu Urban Park Line via the Ibaraki Kyūkō service toward Iwai Shako. Atago Station, further down that same line, is around 30 minutes off by bus or taxi. Anyone driving should allow about 15 minutes from the Bandō interchange on the Ken-Ō Expressway, and will find 10 spaces at the rear plus 2 accessible bays on the south side.
