Four Centuries at the Same Address
The Kani Shōyu Shop and Main House (可兒醤油店舗兼主屋, also written 可児醤油, the firm trading as Kani Shoyu), a Meiji-period townhouse built in 1877 on the Hatchō Ōji shopping street in Usuki City, Oita Prefecture, was entered on the national register of Tangible Cultural Properties on 8 July 2008.
The building faces north onto the street in the hirairi manner, entered from the long side under the eaves rather than from a gable end. It measures six and a half ken across the front and five and a half deep, roughly twelve metres by ten, under a gabled roof of sangawara pantiles. Lean-to eaves run along both the front and the rear, and a further single-pitched roof meets the back of the house at a right angle. The building area is 193 square metres.
Walls are ōkabe, thick plastered surfaces that swallow the structural posts rather than leaving them exposed, finished in white lime. Four mushiko-mado pierce the upper floor: latticed plaster windows whose vertical bars, said to resemble an insect cage, let air and a little light into the living quarters while resisting fire. The ground floor is a mise, a shop with an earth floor; the family lived above it.
The Agency for Cultural Affairs calls it a good example of a large merchant house in Usuki. The scale is the argument. Most surviving machiya on this street are narrower.
Why This One Was Listed for Its Form
Registration criteria for tangible cultural properties come in a short list, and the one applied here matters. Two of the three criteria concern contribution to landscape or rarity; this building was registered under the first, that it serves as a model of form. Among the registered buildings of Usuki that is a relatively uncommon citation, and it points at the building itself rather than its setting.
Registration number 44-0147, sixtieth round of listings, one structure. The register records the decision on 8 July 2008 and the public announcement on 23 July. Alterations date to the late Taisho period, between 1912 and 1925.
Registration is the lighter of Japan's two heritage systems. Where designation as an Important Cultural Property brings permits and restrictions, registration asks owners to notify the state before major changes and leaves the building in working use. For a firm still making soy sauce, that difference is the reason the shop is a shop and not an exhibit.
The neighbouring Kani Shōyu West Shop (可兒醤油西店舗), an older structure from the late Edo period, was registered on the same day as a separate property.
The Oldest Brewer in Kyushu
The house belongs to a business that has been on this spot since 1600. In 1599 the Mino daimyo Inaba Sadamichi was transferred to Usuki, and his retainer Kani Magoemon came ahead of the move. The following year Magoemon and his son Kani Denzō opened a shop called Kagiya on Honmachi and began making miso. The company still uses Kagiya as its trade name, and reckons its founding to Keichō 5, that is 1600.
The firm reorganised as Kani Shōten in 1936 and took its present corporate name in 1963. For a long stretch it sold wholesale to supermarkets and department stores, and the main house served as an office. The twelfth-generation head, who had studied lactic acid bacteria at Tokyo University of Agriculture, brought retail back into the building and restarted sales by measure.
So the ground floor still functions as a shop, with a small café attached; miso soft-serve has become the item most visitors come for. Opening hours and closing days change, and the company's own site is the place to check before making the trip. The shop stands about fifteen minutes on foot from JR Usuki Station, midway along the arcade that Usuki renamed Hatchō Ōji in 2003. Two other soy sauce makers trade on the same street, both founded centuries later than this one.
South of the arcade the ground rises into Nioza, a hill of welded tuff cut through with stone-paved lanes and temple walls. The National Treasure Usuki Stone Buddhas lie a short drive inland. A visit that takes in the brewer, the hill and the cliff carvings covers most of what Usuki is known for.

Q&A
- Can you go inside the Kani Shōyu Shop and Main House?
- Yes. The ground floor operates as a working shop selling miso and soy sauce, with a small café attached, so entering as a customer is the ordinary way to see the interior. The upper floor is private living space. Hours and closing days change, so check the company's website before travelling.
- How old is the business behind the Kani Shōyu Shop and Main House?
- The firm dates its founding to 1600, when Kani Magoemon and his son Denzō opened a shop called Kagiya on this site after following the Inaba clan from Mino to Usuki. It is described as the oldest miso and soy sauce maker in Kyushu. The present building, however, was put up in 1877.
- When was the Kani Shōyu Shop and Main House registered, and on what grounds?
- It was registered on 8 July 2008 as a Registered Tangible Cultural Property (structure), number 44-0147, sixtieth round. The criterion cited was that the building serves as a model of form, which points to its architecture rather than to its role in the streetscape.
- What should you look at on the facade of the Kani Shōyu Shop and Main House?
- The four mushiko-mado on the upper floor, latticed plaster windows set into thick white lime ōkabe walls, and the lean-to eaves running the width of the front. The gabled pantile roof and the six-and-a-half-ken frontage give the building a breadth that stands out along the arcade.
- How do you get to the Kani Shōyu Shop and Main House from JR Usuki Station?
- It is roughly a fifteen-minute walk, in the middle of the Hatchō Ōji arcade in central Usuki. The Nioza historic lanes begin just south of the arcade, and the Usuki Stone Buddhas are a short drive inland.
