A brewing warehouse raised in 1895
The Former Otsuka Sake Brewery Main Storehouse (旧大塚酒造本蔵, Kyū Ōtsuka Shuzō Hongura) is a two-story timber brewing warehouse of 1895 (Meiji 28) at 3351-2 Iwai in Bando City, Ibaraki Prefecture, entered on the national register as a Registered Tangible Cultural Property on May 2, 2017 (Heisei 29). With a footprint of 795 square meters, it is among the largest Meiji brewery buildings still standing in western Ibaraki.
The house that built it was not called Otsuka. The plot belonged to Aizawa Shuzō, a brewing family established in the Tenpō era (1830 to 1844) near the end of the Edo period, which added warehouse after warehouse to the yard between the middle of the Meiji era and the Taishō era. The date of this one is written on the building itself. On the underside of the ridge beam on the second floor, an ink inscription gives the 7th month of 1895 and names the head of the Aizawa house (相澤子之吉), then 27 years and 9 months old, along with the master carpenter Yamanaka Yonekichi (山中米吉).
Aizawa Shuzō stopped brewing in 1931 (Shōwa 6). Otsuka Eikichi, a sake merchant from Noda in Chiba Prefecture who had been trading with the family, took over the ground, the buildings and the entire brewing plant, and ran it from then on as Otsuka Shuzō. The house label was Shūroku, a name taken from ryokushu, an old word for good sake that appears in a line of Chinese verse. Output peaked at roughly 360,000 liters a year around 1985 (Shōwa 60). Brewing ended in 2011 (Heisei 23), and Bando City acquired the property.
Why the building carries a registration
The Former Otsuka Sake Brewery Main Storehouse holds the status of Registered Tangible Cultural Property, which is granted under the registration system introduced in 1996 (Heisei 8) rather than by designation. It was accepted under the criterion covering buildings that contribute to the historic landscape of Japan, and it is recorded as Registered Tangible Cultural Property number 08-0298, counted as 1 building.
Large timber breweries of this age rarely come through intact. Most were pulled down when the business closed, or cut up into smaller units, or lost their upper floors to earthquake damage. This one kept its full plan, its structural frame and its roof through the Great Kantō Earthquake of 1923 (Taishō 12) and the Tōhoku earthquake of 2011 (Heisei 23), and the repair carried out in 2016 (Heisei 28) treated the frame as the thing worth keeping. What the register recognizes, in other words, is not decoration. It is an industrial building that still explains how sake was made on a commercial scale in a country town.
Ten pillars, larch beams, and holes in the floor
Inside the Former Otsuka Sake Brewery Main Storehouse the eye goes upward before it goes anywhere else. The main body of the building is 17 Ken long and 6 ken deep, with Geya lean-to ranges 3 ken wide attached on 3 sides, and the roof is Kirizuma-zukuri covered in Sangawara-buki pantiles. The ground floor covers about 790 square meters, the upper floor about 170.
Down the center run 2 rows of pillars, 10 in all, rising unbroken from the ground floor through both stories. Each is roughly 300 millimeters square. They are the reason the interior reads as a single volume rather than a run of separate bays, and standing next to one gives a fair sense of what timber at that scale feels like up close.
The beams are Japanese larch, karamatsu. Larch is hard and slow to rot, but it twists as it dries, which is why builders usually avoid it. In a brewery, where water is used constantly and the air never dries out, that objection falls away. Somebody in 1895 knew this.
The second floor carries a Wagoya roof truss, timbers crossing overhead in plain sight. Look down instead and you find round openings set into the floorboards, in two sizes, each with its own lid. Poles were almost certainly dropped through them into the vats below so that the mash could be stirred from above.
More than 40 tanks holding between 6,000 and 8,000 liters once stood on the ground floor. A few stand there still, though they now form part of the air-conditioning rather than the brewing. The wooden lids that once covered them were cut up and relaid as floorboards in the shop and main house at the front of the site.
Visiting the Former Otsuka Sake Brewery Main Storehouse
The building is open to the public. It stands inside 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 and takes its name from the old sake label. Admission is free, the site is open 10:00 a.m. to 6:00 p.m., and it closes on Mondays, or on the following day when a Monday falls on a public holiday.
The ground floor of the Former Otsuka Sake Brewery Main Storehouse works as a multipurpose hall and is hired out for concerts, meetings and reunions, so it is sometimes occupied or closed off. The lean-to along the side is used for displays. A telephone call to 0297-35-0002 before setting out is worth the trouble if you want the hall empty. No rule on photography has been published; during an event, ask at the front desk. Sake is no longer made anywhere on the site.
The nearest bus stop is Honchō, 1 minute on foot. From Moriya Station on the Tsukuba Express, Kantō Railway buses bound for Iwai Bus Terminal call there, and the ride takes about 40 minutes; from Noda-shi Station on the Tōbu Urban Park Line, Ibaraki Kyūkō buses bound for Iwai Shako do the same. Atago Station on the same line is about 30 minutes away by bus or taxi. Drivers reach the site in about 15 minutes from the Bandō interchange on the Ken-Ō Expressway. There is parking for 10 cars behind the storehouse and 2 accessible spaces on the south side.
