A Meiji Soy Sauce Warehouse That Moved House
Yamahisa Nishi Moromigura (ヤマヒサ西諸味蔵, also written Yamahisa Nishi-moromi-gura) is a single-storey wooden soy sauce warehouse in Yasuda, Shodoshima Town, Kagawa Prefecture, built in 1900 (Meiji 33) and re-erected on its present site in 1949 (Showa 24); it was listed as a Registered Tangible Cultural Property on 31 January 2003.
The building stands at an irregular four-way junction east of the Uchinomi post office, on rising ground north of Yasuda Port on Uchinomi Bay. Its ridge runs north to south, which means the short south gable end is what meets the road. Anyone walking up from the harbour sees that gable first: a broad triangle of weathered cedar boarding above a plain eaves line, with no signboard and no ornament to soften it.
The frame measures ten bays along the ridge by five across, under a gabled kirizuma roof of sangawara pantiles. A lean-to, called a shitaya, runs the length of the east flank and gives the silhouette its slightly lopsided profile. The Agency for Cultural Affairs records a footprint of 200 square metres. Cedar boarding covers the walls, following the convention used by soy sauce makers throughout this part of the island.
Moromi is the fermenting mash at the centre of the trade. Steamed soybeans and roasted cracked wheat are inoculated with koji mould, mixed with salt brine, and left in cedar vats to work for a year or longer before pressing. A moromigura is simply the building that holds those vats, and this one still does. Yamahisa presses its soy sauce from mash aged across two summers, which is several times longer than industrial practice.
Why the Building Is Listed
Registration number 37-0141, granted in the thirty-fifth round of national registrations and gazetted on 26 February 2003, cites one criterion: the building contributes to the historic landscape of the country. That phrasing matters. The listing is not about a rare structural technique or an architect's reputation. It recognises that Yasuda reads as a soy sauce town partly because of buildings like this one.
Registered Tangible Cultural Property is a lighter category than the Important Cultural Property designation applied to temples and castles. Introduced in 1996 for buildings roughly fifty years old and upward, it obliges the owner to notify the authorities before altering the exterior, but otherwise leaves the property in working use. Almost every listed structure in the Yasuda and Umaki districts is a shed, a warehouse or a merchant house still doing its original job.
The relocation is the detail worth dwelling on. Japanese timber framing is jointed rather than nailed, so a building can be dismantled, carted and raised again on a new site with most of its members intact. Yamahisa was founded in 1932; by the late 1940s it needed more mash capacity, and rather than build from scratch in a period of severe material shortage it acquired a Meiji-era brewery and moved it here. The Agency's record keeps the two dates apart, listing the period as Meiji and the year as 1900, with the 1949 move noted separately.
A warning about names. Three separate companies on Shodoshima own a listed building called Nishi Moromigura: Yamahisa here in Yasuda, Yamaroku Shoyu a short walk away in the same district, and Shokin Shoyu over in Umaki. The Shokin and Yamahisa buildings were even registered on the same day. If you are searching records or asking directions, use the company name.
Seeing It for Yourself
This is a factory, not a museum. The warehouse holds working vats, and there are no interpretation panels, no ticket desk and no set opening hours for the building itself. What you can do freely is stand on the public road and look at the south gable, which is the elevation the registration documents describe.
Yamahisa keeps a shop on the site, open from 8:00 to 17:00 and closed on Sundays, public holidays and the second and fourth Saturdays of the month. Staff will show visitors the brewing floors if you telephone ahead on 0879-82-0442; unannounced arrivals may find everyone mid-batch. Ask before photographing inside, since the mash room is a food production area.
Two things reward a slow look. The first is the cedar boarding, which has silvered unevenly depending on how much weather each face takes, so the south gable and the sheltered east side are noticeably different colours. The second is the lean-to roof along the east flank, a working addition rather than a designed feature, sloping at a shallower pitch than the main roof and meeting it in a join you can trace from the ground.
Getting here: ferries from Kobe and from Takamatsu-Higashi dock at Sakate Port, and Olive Bus services on the Sakate line stop at Yasuda, about five minutes on foot from the brewery. Several other listed warehouses stand within a short walk, among them those of Yamaroku Shoyu and Takahashi Shoten, so the visit is easily combined.

Q&A
- Can visitors go inside Yamahisa Nishi Moromigura?
- Not on a walk-in basis. The warehouse is an active production building. Yamahisa accepts brewery visits arranged in advance by telephone on 0879-82-0442, and the shop on the same site is open to anyone during business hours. The exterior can be viewed at any time from the public road.
- When was Yamahisa Nishi Moromigura built, and how old is the building really?
- The structure dates from 1900, but it did not stand in Yasuda until 1949, when it was dismantled at its original location and re-erected here. Both dates appear in the Agency for Cultural Affairs record.
- Where exactly is Yamahisa Nishi Moromigura, and how do I get there?
- The address is 243-1 Shinkai-ko, Yasuda, Shodoshima Town, Shozu District, Kagawa Prefecture. Take a ferry to Sakate Port from Kobe or Takamatsu-Higashi, then an Olive Bus on the Sakate line to the Yasuda stop; the brewery is about five minutes away on foot.
- What is the difference between Yamahisa Nishi Moromigura and Yamahisa Kita Moromigura?
- They are neighbouring warehouses on one site, listed together in 2003. The west warehouse dates from 1900 and was moved here in 1949, covering 200 square metres. The north warehouse was purpose-built in 1932 when the company was founded, covers 220 square metres, and carries the firm's Yamahisa mark on its north gable.
- Is Yamahisa Nishi Moromigura still used for making soy sauce?
- Yes. It houses cedar vats of fermenting mash, and Yamahisa continues to brew there using domestic whole soybeans, domestic wheat and sun-dried salt, with fermentation running across two summers.
