Shioya Brewery

What Shioya Brewery Is

Shioya Brewery (塩屋醸造, Shioya Jōzō) is a miso and soy sauce maker's premises at 537 Oaza Suzaka in Suzaka City, Nagano Prefecture, where ten buildings dating from the late Edo period through the Meiji era, among them the shop and main house, the uwamise, the soy sauce storehouse and the miso storehouse, were listed as Registered Tangible Cultural Property on 15 May 2007. Each of the ten is a separate listing with its own register number, running in sequence from 20-0302 to 20-0311.

Suzaka City introduces the property as the Shioya soy sauce shop of Shinmachi and notes that it was already trading by the closing years of the shogunate. Along the street stand the soy sauce storehouse, the uwamise (上店, the upper shop), a gate and the shop in a single line; behind the shop runs the family house, and behind that a crowd of brewing storehouses. The city describes it as a large merchant house that shapes the historic streetscape of Shinmachi.

The listed buildings are still a workplace. Shioya Brewery Co. continues to brew miso and soy sauce on the site, and the street-front shop operates as the company's own outlet. Inside the listed storehouses, wooden vats hold next year's miso as it matures.

From Salt Merchant to Brewer

The name Shioya, literally the salt house, is the family's origin in a word. According to the history published by the owners, the business was founded in the middle of the Edo period, in the 1700s, as a salt wholesaler, with Shioya Seiemon as its first head. In the Bunka and Bunsei eras (1804 to 1830) it began brewing miso and soy sauce, and it has done so ever since.

Landlocked Shinshu had to bring in every grain of its salt. The owners describe several routes by which salt reached Suzaka: overland from Naoetsu on the Sea of Japan by the Hokkoku Kaido highway and over the Tomikura Pass, and by boat on the Chikuma River. For a merchant who already controlled one of the key ingredients, moving into miso and soy sauce was a logical step.

In a 2025 interview, the eleventh-generation head of the family explained the change in practical terms. Salt in those days held a lot of moisture and would slowly dissolve and lose weight in storage; turned into miso or soy sauce, it kept. He also connected the business to Suzaka's silk boom in the Meiji and Taisho eras: as more people went to work in the reeling mills and lived in company dormitories, fewer households had time to make their own miso, and shop-bought miso became a trade in its own right.

The sources do not agree on dates. The owners' history places the founding in the 1700s, while the same family head, in the interview, put the start of brewing at about two hundred years ago. Suzaka City says only that the shop was operating by the end of the shogunate. This article follows the owners' history, which dates the salt business to the mid-Edo period and brewing to the Bunka and Bunsei eras, and gives the city's more cautious statement alongside it.

As a company, the firm was incorporated as a partnership, Shioya Shoyuten, in 1932, became a limited company in 1950, and took its present name, Shioya Brewery, in 1985.

How the Site Is Laid Out

Shioya Brewery's lot meets the city road on its north side. Seen from the street, the frontage runs from west to east as the soy sauce storehouse, the uwamise, the gate and the shop and main house. The storehouse turns a broad gable to the street, the uwamise carries its upper eaves out on projecting beams, and the main house has its upper walls and eaves sealed in plaster. Three different faces in a row are what make the frontage worth walking slowly.

Along the west edge of the lot, the Tezukuri Storehouse and the Grain Storehouse follow the soy sauce storehouse southward, and the Moromi Storehouse stands in the southwest corner. The largest building on the site, the Miso Storehouse, lies along the south edge facing north. The brewing buildings gather on these two sides.

On the other side of the lot, the Document Storehouse stands south of the main house, the Small Document Storehouse to its east and the Detached Wing to the southeast. These belong to the domestic side. Shop, brewery and home share one address, and the boundaries between them can be read in the placement of the buildings.

The owners' own description of the site says that once you pass under the great noren curtain, a screen of rock stands directly ahead and the Tezukuri Storehouse appears on the right. The rock was brought in as a partition between the house and the brewery. When it was set down it is said to have stood upright of its own accord, and it has been called the engi-ishi, the lucky stone, with a family rule that it must never be moved.

• Detached Wing (late Meiji, altered 2003; register no. 20-0303)

All ten were listed under the same criterion, contribution to the historic landscape of the nation. The listing values the ensemble that survives as a brewer's premises rather than any single building on its own design merits.

Visiting and Getting There

Shioya Brewery offers a free brewery tour of about 30 minutes. The main stops are the Miso Storehouse, lined with wooden vats, and the Soy Sauce Storehouse, where the soy sauce is pressed. Walk-in requests are accepted, but staff may not always be free to guide, so booking ahead is the safer course if your plans are fixed. Visitors who book are offered amazake and miso soup, subject to availability (checked 27 September 2026).

According to the online shop, the outlet is open 9:00 a.m. to 5:15 p.m. on weekdays and 10:00 a.m. to 4:00 p.m. on weekends and public holidays, closing only on 1 January, with occasional irregular closures. The owners' main website still gives 9:00 a.m. to 6:00 p.m., so phone ahead if you are arriving near closing time (checked 27 September 2026).

No public access is advertised for the domestic buildings, the Document Storehouse, the Small Document Storehouse and the Detached Wing, or for the living quarters of the main house. The north faces of the soy sauce storehouse, the uwamise, the gate and the shop line the street and can be seen at any hour.

We found no statement on photography in the official information (checked 27 September 2026). The storehouses are working spaces where miso and soy sauce are made and matured, so ask your guide before taking pictures inside.

By rail, take the Nagano Electric Railway from JR Nagano Station to Suzaka Station, a ride of roughly 25 minutes, then walk about 16 minutes. By car, leave the Joshin-etsu Expressway at Suzaka-Nagano-Higashi Interchange and head into the town. The car park is diagonally across the road from the shop.
