Sanyo Tsuru Sake Brewery Kuromatsu No. 1 Brewery

The Broad Roof That Anchors Saijo's Brewery District

Sanyotsuru Shuzo Kuromatsu No. 1 Warehouse (山陽鶴酒造黒松一号蔵, also written Sanyōtsuru Shuzō Kuromatsu Ichigō-gura) is a Taisho-period sake storehouse in Okamachi, Saijo, Higashihiroshima City, Hiroshima Prefecture, listed as a Registered Tangible Cultural Property (Structure) on 1 August 2016.

The building sits toward the southern edge of the Sanyotsuru brewery compound. It is a dozo, a storehouse built with thick earthen walls over a timber frame, raised to two storeys and roofed in a gable that presents its long side to the approach. The main body measures six ken by five ken, close to 10.9 by 9.1 metres, and lean-to extensions run along the west and south faces. At 207 square metres of building area it is the largest of the three Kuromatsu warehouses registered together in 2016.

What registers first is not the wall but the roof. Pantiles in a warm reddish clay cover a plane wide enough to read from several streets away, and the gable end rises above the neighbouring rooflines as a plain triangle of tile and boarding. Below the eaves the walls are clad in horizontal weatherboard rather than the white plaster many visitors expect of a Japanese storehouse, a practical skin that protected the earthen core from Saijo's rain.

Inside the roof, the carpenters used a truss. That detail matters more than it looks: a Western-derived triangulated frame let the builders span the interior without a forest of posts, which is exactly what a brewery needs when its floor has to hold rows of fermentation vessels. The mixture of imported structural thinking and traditional earthen construction is the signature of Japanese industrial building in the 1910s and 1920s.

Why a Working Brewery Building Carries National Status

Japan protects its heritage buildings under two quite different systems, and the distinction is worth understanding before you visit. Designation as a National Treasure or Important Cultural Property is reserved for a small number of buildings judged to be of outstanding value, and it comes with tight controls on any alteration. Registration, introduced by amendment to the Law for the Protection of Cultural Properties in 1996, is deliberately lighter. It was created for the enormous stock of modern buildings, factories, shops, bridges and warehouses among them, that were disappearing faster than the designation system could ever address.

A registered property may still be repaired, adapted and used commercially, with notification required only for major changes to the exterior. For a brewery that still makes sake, this is the difference between protection and paralysis.

The No. 1 Warehouse was registered under the criterion of contributing to the historic landscape of the country, entered as registration number 34-0203 in the eighty-fourth round of registrations announced on 1 August 2016. The Agency for Cultural Affairs record singles out the expanse of red tile and the gable face as the elements that give shape to the Saijo townscape. In other words, the value recognised here is partly architectural and substantially urban: this building matters because of what it does to the street.

That reading fits the wider story. Saijo ranks alongside Nada in Hyogo and Fushimi in Kyoto as one of Japan's three great sake districts, and its rise was recent rather than ancient. Miura Senzaburo, a brewer from what is now the Akitsu district of Higashihiroshima, worked out a method for brewing well with soft water and published his findings in 1898, overturning the assumption that the region's mineral-poor water made good sake impossible. The Sanyo Railway had reached Saijo in 1894, opening markets in Osaka and Tokyo. Breweries expanded northward from the old highway toward the station through the Taisho years, and the Kuromatsu warehouses belong to precisely that wave of building. In 2017 the Japanese National Committee of ICOMOS placed the Saijo brewing complex on its list of twenty pieces of Japanese twentieth-century heritage.

Seeing It: What to Look For, and What You Can Actually Enter

Be clear about one thing before you set out. The No. 1 Warehouse is private working property, not a museum. Sanyotsuru does not run regular tours of the warehouse interiors, and the building is appreciated from outside. What is open to you is the company's shop, and the shop is a short walk from the warehouse yard.

Sanyotsuru Shuzo stands at 6-9 Okamachi, about five to seven minutes on foot from the north exit of JR Saijo Station on the Sanyo Main Line. The brewery's own site gives office hours of 9:00 to 17:00 on weekdays and a retail counter open 13:00 to 17:00, closed Sundays and public holidays, though tourist listings quote a slightly different retail schedule and the hours shift around brewing season. Check before you go if the shop is the point of your trip. Photography of the exteriors from public streets is unrestricted; the yard and interiors are another matter, and asking at the office costs nothing.

Standing outside, look for three things. The junction where the No. 1 Warehouse meets the No. 2 Warehouse at the rear gable, which tells you the two were conceived as a pair. The lean-to roofs on the west and south, lower and shallower than the main pitch, added to give covered working space against the wall. And the boarding itself, laid in overlapping horizontal courses that throw a fine line of shadow across the elevation in raking afternoon light.

Two moments in the year change the experience completely. The Sake Matsuri each October fills the streets around the station, with the seven Saijo breweries opening as festival venues. In April the breweries hold kurabiraki, opening days for the new season's sake, and Sanyotsuru usually takes one of the earliest weekends. On ordinary days the district is quiet, and a slow forty minutes on foot will take you past red brick chimneys, plastered walls and the white-walled fronts of six other breweries along the roughly one-kilometre stretch known as the Sakagura-dori.

A note on the name. The brand is Kuromatsu Sanyotsuru, kuromatsu meaning black pine: the company took the pines that once lined the Sanyodo highway and added a crane, tsuru. The warehouses carry the brand name rather than a number alone, which is why the register lists them as Kuromatsu No. 1, No. 2 and No. 3.
