Yamasu Sakashita Family Residence Nagayamon

The Gate That Was Built First

The Yamasu Sakashita Family Residence Nagayamon (やます坂下家住宅長屋門, Yamasu Sakashita-ke Jūtaku Nagayamon) is a single-storey timber gatehouse at Sakanoyama in Shodoshima Town, Shozu District, Kagawa Prefecture, built in 1908 and entered on Japan's national register of Tangible Cultural Properties on 9 February 2005.

It went up nine years before the house it guards. The main house on the same plot dates from 1917, and the small Western annex attached to that house from 1922. Reading the compound in the order it was built means starting at the gate and working inward, which is the reverse of how most Japanese country estates were assembled.

A nagayamon is a gate carved out of a long, low building range. Instead of a freestanding portal, the opening is cut through the middle of what is otherwise a row of rooms used for storage, for servants' quarters, or for stabling. The form began with samurai residences and spread during the Edo and Meiji periods to landowning and merchant families who wanted a street frontage that announced their standing without the cost of a formal ceremonial gate.

This one measures 111 square metres in floor area and runs roughly 14 metres along its ridge, which is set north to south. The roof is gabled and covered in sangawara pantiles. Lean-to roofs (geya) run down both the east and west flanks, giving the building a broad, low silhouette that hugs the slope.

An Entrance That Does Not Behave

The detail that catches the eye of anyone who looks at gatehouses is where the opening sits. On a conventional nagayamon, the doorway is punched straight through the long face, centred or nearly so, and you walk through on the building's main axis. Here the opening is set inside the east-facing lean-to. You pass under a subsidiary roof before you reach the gate proper, then continue west into the yard toward the house.

The Agency for Cultural Affairs record calls this approach a distinctive composition, and the wording is unusually direct for a database that normally deals in measurements. A visitor arriving from the lane below does not get the flat, symmetrical presentation that a gatehouse is supposed to deliver. The entry is oblique, tucked under an overhang, closer in feeling to a side door than a front gate.

At some point in the middle of the Taishō era, between 1912 and 1925, the family added another single-storey gabled wing at the south end of the west face, its ridge turned to run east and west. The addition is not disguised. Look along the west elevation from inside the yard and the change in direction is plain.

Two circular windows survive from this phase of work. One is cut into the small wall panel under the eaves on the west side; the other pierces the west gable end of the added wing. Round openings of this kind belonged to the vocabulary of Meiji and Taishō decorative carpentry, and their placement here is worth noticing: both face inward, into the family's own courtyard, not out toward the road. Whoever commissioned them was decorating the view from the house rather than the view from the lane.

Why It Carries a Registration Number

Japan runs two parallel systems for protecting buildings. Designation, which produces National Treasures and Important Cultural Properties, is the older and stricter route. Registration, introduced in 1996, is deliberately lighter. Owners notify the state of alterations rather than seeking permission, receive tax relief and technical advice, and are expected to keep using the building. The system was designed for exactly this category of asset: privately owned, still lived in, valuable as part of a place rather than as an isolated masterpiece.

The gatehouse holds registration number 37-0250 and was processed in the forty-fifth round of registrations, gazetted on 28 February 2005. The criterion applied is contribution to the historic landscape of the nation. Its neighbours on the same plot were registered on the same day: the main house as 37-0249, under the different criterion of being a model of design, and the Western annex as 37-0251.

The registration covers more than the building. Thirty metres of stone retaining wall are included in the listing. That wall is what made the site usable at all. The Sakashita plot occupies a shelf cut into the foot of the hills behind the coast, and the terrace holding the house, the gate and the annex was built up with stone before any timber went in. Listing the retaining wall alongside the gatehouse acknowledges that on a slope like this, the groundwork is part of the architecture.

The Hillside Above the Soy Sauce Sheds

Shodoshima has been brewing soy sauce for more than four centuries. Salt-making came first, brought by workers who settled here from Akō in the late sixteenth century, and brewing grew out of it. At the height of the Meiji boom the island supported several hundred brewing houses. The surviving concentration of breweries, fermentation sheds and merchant homes along the road between Yasuda and Sakate is now promoted as Hishio no Sato, the Village of Fermented Seasoning.

Most visitors experience Hishio no Sato at sea level, where the black board walls of the working breweries line the road. The Sakashita compound sits about a kilometre inland and uphill from that strip, in a hamlet where the families who profited from the trade built their homes away from the sheds.

The naming tells you how the neighbourhood worked. Yamasu is a yagō, a house mark of the kind merchant families used as a trading identity, and it is fixed to the family surname Sakashita in the official title. The same construction appears all around this hillside in the register: Kikkoishi Ishii, Yamayoshi Yamamoto, Kinryō Fujii, Shōkin Fujii. Reading the list of registered buildings for Shodoshima Town is close to reading a directory of the brewing trade.

Two other registered compounds stand within a couple of hundred metres. The Kikkoishi Ishii Family Residence at number 262 contributed seven separate registrations, including its own gatehouse and a soy sauce store. The Sakashita Tsutomu Family Residence at number 258 added three more in 2006. Very few Japanese hamlets carry this density of registered buildings, and the effect when walking through is cumulative rather than singular.

Seeing It: What Is and Is Not Possible

The Yamasu Sakashita compound is a private home. There is no admission, no opening period and no interior access, and none of the three registered buildings has ever been opened as a visitor attraction. What you can do is walk the lane and look. The buildings stand close to the public road, and their exteriors read clearly from it.

The nearest bus stop is Marukin-mae (丸金前) on the Olive Bus Sakate line, beside the Marukin Soy Sauce Museum. From there it is roughly a kilometre on foot, most of it climbing, and the walk takes about fifteen to twenty minutes at an unhurried pace. The Umaki walking trail (馬木散策路), a signed route through the same hamlet, passes within a few hundred metres and is the sensible way to arrive.

Photography from the public road is not restricted, but this is somebody's house. Keep off the private approach, do not photograph through windows, and treat the courtyard as off limits. Local guides run occasional walking tours of the Umaki route by prior arrangement; those cover the working breweries rather than this compound, and they are worth booking if you want the trade explained by someone who grew up in it.

The Marukin Soy Sauce Museum, ten minutes' walk downhill, is the one building in the area reliably open to the public. It occupies a former pressing plant of the early Taishō era, itself registered in 1996, and is generally open from 9:00 to 16:00 with an admission charge and seasonal extensions. Hours change, so check before you set out.
