A 1932 Company Office on a Castle-Town Street
The Usukuchi Tatsuno Soy Sauce Museum (うすくち龍野醤油資料館, also written Usukuchi Tatsuno Shōyu Shiryōkan) is a museum in Tatsuno City, Hyōgo Prefecture, occupying a two-storey timber building of 1932 that entered Japan's national register of Tangible Cultural Properties on 18 April 2008.
Stand on the pavement and the first puzzle is the wall. Heavy pilasters rise the full height of the front, faced in tile of a warm reddish tone; the plinth and the upper edges are clad in stone. The eye reads masonry. The structure behind that surface is wood.
The building presents its north face to the street. A two-storey central block sits between single-storey wings, and the pilasters divide that block into two broad bays. An arch spans the ground floor. Above it, slender colonnettes cut the upper storey into three. The Agency for Cultural Affairs records a building area of 687 square metres under a tiled roof.
Kikuichi, Tatsuno, Higashimaru
The office went up for Kikuichi Shōyu, a brewing firm established by the Kataoka family. A merger with Asai Shōyu produced Tatsuno Shōyu, which later renamed itself Higashimaru Shōyu. Through both changes the building stayed in use as the company headquarters.
Its second life began in November 1979, when the old office and an adjoining Edo-period brewing warehouse were refitted as a museum devoted to soy sauce. The operator describes it as the first such museum in Japan. That 1979 remodelling is recorded in the national register alongside the original construction year.
Why the Building Was Registered
Registration number 28-0356 was granted under a single criterion: contribution to the historic landscape of the nation. The registration date is 18 April 2008 and the public notice followed on 7 May of the same year.
The surrounding quarter is a low run of plastered brewery walls and merchant frontages in grey and ochre. A Western-style facade in brick tones ought to jar. It does not, quite, and the register treats that tension as the building's contribution rather than a flaw. Hyōgo Prefecture had already listed it as an Important Landscape Building, and it carries national recognition as heritage of industrial modernisation.
Ownership rests with the Higashimaru Memorial Foundation (財団法人東丸記念財団). The collection housed inside holds separate status: some 2,400 brewing implements and documents assembled by the Tatsuno soy sauce cooperative are designated a Tangible Folk Cultural Property by Hyōgo Prefecture.
What Rewards a Slow Look
The route through the displays follows the order of the work rather than the order of the calendar. An Edo-period draw-well opens the sequence, once fed by groundwater from the Ibo River. Then the raw-material handling floor, the fermentation room, the kōji muro where the mould culture was raised in cedar trays.
A word on the product, since the name of the museum turns on it. Usukuchi means light in colour, not light in salt; the style carries slightly more salt than the darker koikuchi soy sauce common elsewhere in Japan. Rice is among its raw materials, which surprises visitors who expect only soybeans, wheat and salt. Local accounts credit the pale result to the soft, low-iron water of the Ibo, salt brought from nearby Akō, and wheat and soybeans grown on the Harima plain.
A film of about fifteen minutes covers the climate of the district and the brewer's craft. A gallery on the grounds, set in a former brewing warehouse, shows work by the painter Yamashita Maki.
Practical points worth knowing before you set out. Opening hours run 9:00 to 17:00, with last admission at 16:30, and the museum closes on Mondays unless the Monday is a public holiday. Tourism listings give admission as ten yen for every visitor regardless of age, which is a fair candidate for the cheapest museum ticket in the country. JR Hon-Tatsuno Station lies roughly 1.3 kilometres away, about twenty minutes on foot through the old town. An annex two minutes further on covers the history of Tatsuno brewing and shares the same ticket. Photography rules inside are not published; ask at the desk.

Q&A
- Can visitors go inside the Usukuchi Tatsuno Soy Sauce Museum, and what does it cost?
- Yes. The building works as a public museum. Hours are 9:00 to 17:00 with last entry at 16:30, and closure falls on Mondays except when that Monday is a public holiday. Tourism listings quote admission at ten yen per person, the same for adults and children, though it is sensible to confirm before a long trip.
- How do I reach the Usukuchi Tatsuno Soy Sauce Museum from the nearest station?
- JR Hon-Tatsuno Station on the Kishin Line is the closest, about 1.3 kilometres from the museum, or roughly twenty minutes on foot. The walk runs through the surviving grid of the castle town, so allow extra time for looking around.
- Is the Usukuchi Tatsuno Soy Sauce Museum building really made of brick?
- No. The frame is timber. What produces the masonry effect is a facing of tile on the pilasters, with stone at the base and the upper edges. The Agency for Cultural Affairs describes the building as wooden, two storeys, with a tiled roof and a floor area of 687 square metres.
- What is displayed inside the Usukuchi Tatsuno Soy Sauce Museum?
- Around 2,400 brewing implements and documents dating back to the Edo period, arranged to follow the production sequence: the well, raw-material handling, the fermentation room and the kōji chamber. The collection is designated a Tangible Folk Cultural Property by Hyōgo Prefecture. A short film and a painting gallery complete the visit.
- Why does the Usukuchi Tatsuno Soy Sauce Museum matter to the history of soy sauce?
- Tatsuno is where usukuchi, the pale style of soy sauce that underpins much of Kansai cooking, took commercial shape. The building served as headquarters for the firm that became Higashimaru Shōyu, and its conversion in 1979 created what the operator calls the first soy sauce museum in Japan.
