Kobayashi Family Main Building

Kobayashi Family Residence: An Inn Rebuilt from the Ashes

Fire decided a great deal of what survives in Motoyama. The old post town on the Nakasendō highway burned more than once, and the wooden inn the Kobayashi family put up after the blaze of 1869 still faces the road much as it did then. Its upper floor reaches out over the street on two stacked tiers of projecting beams, a doubled framing that is uncommon even along this timber-rich stretch of the Kiso country.

The building is one of three former inns standing side by side in an unbroken line, each listed on Japan's register of tangible cultural properties. Travellers know the family by its trade name, Kawaguchiya. For generations the Kobayashi ran a hatago here, the kind of working inn that fed and lodged ordinary people walking the road between Edo and Kyoto. The residence has been on the register since January 2011.

What sets the Kobayashi house apart from its neighbours is the depth of that overhanging front. Where most post-town townhouses carry their second story on a single run of beams, this one does it twice over, giving the facade a layered, shadowed projection that the city's own records single out as the mark of a large, well-appointed inn.

Motoyama, the 32nd Stage on the Nakasendō

The Nakasendō was one of the five great highways of Edo-period Japan, an inland route that threaded through the central mountains to link the shogun's capital with Kyoto. Motoyama stood as its thirty-second station counting out from Edo, set at the point where the road leaves the open Matsumoto basin and turns south into the wooded gorges of the Kiso valley.

Unlike the neighbouring stations of Shiojiri and Seba, which were assembled by moving households in from nearby villages when the route was fixed in 1614, Motoyama was already a settlement of long standing. By 1843, official records counted 117 houses here, one principal inn for officials, one secondary inn, and thirty-four ordinary hatago, with a population just under six hundred. Frontages along the street ran wider than at Seba, which is part of why the surviving facades feel so substantial.

The town has another claim that draws visitors. A 1706 anthology of haikai prose names Motoyama as the place where soba-kiri, buckwheat dough cut into the thin noodles eaten today, first appeared before spreading across the provinces. The origin of cut soba is genuinely disputed, with rival traditions and an older written reference from a temple deeper in Kiso, so the claim is best read as one well-documented strand rather than the settled truth. It is still celebrated in the town, and you can taste the local style at a soba house run by a women's cooperative just off the old road.

Why the House Is on the Register

Japan's register of tangible cultural properties is a lighter form of protection than the better-known designations for national treasures and important cultural properties. It was created to safeguard a broader range of buildings, generally at least half a century old, that hold value as models of their type. The Kobayashi residence was registered under the criterion of serving as a standard of design.

Three things make the case. The first is the rarity of the double projecting-beam construction, which appears in few other buildings even in a region defined by this style of carpentry. The second is the completeness of the property as a unit: behind the main building, the plot still holds a detached wing and an earthen-walled storehouse, with a garage facing the road, so the layout of a real working inn can still be read. The third is the streetscape. The Kobayashi house does not stand alone. Together with the Akiyama and Tanaka residences it forms a continuous run of three listed townhouses, and it is that unbroken row, rather than any single facade, that carries the feeling of the old stage town.

What to Look for at the Front

Stand across the road and start with the eaves. The projecting-beam method, dashibari, works by running floor beams outward past the wall line so the second story and its eaves hang over the street below. Here the device is doubled into two tiers, one set above the other, which is why the front seems to step forward in stages as it rises.

Above that, the whole width of the second floor is closed by senbon-goshi, a screen of fine vertical slats set close together. From the street they read as a solid wooden grille; from inside they let light and air through while keeping the room private. At each end of the facade sits a sode-udatsu, a short projecting wall that once helped check fire from spreading between neighbours, the very danger that shaped this town. At ground level, near the entrance, look for the shikidai, a low formal step-board that marked a more ceremonious threshold than a plain doorway.

The three houses reward a slow walk. The Akiyama residence at one end is narrower, its upper floor pushed out on simple bracket arms; the Tanaka house carries a raised roof vent and posts finished in red-brown bengara lacquer. Reading the differences between them is the real pleasure of the row.

Around the Old Post Town

The Kobayashi residence and its neighbours are private homes. They are admired from the street rather than entered, so plan your visit around the exterior and the wider town, and be considerate of the people who live behind these walls.

A short way south of the town stands one of the most photographed markers on the whole highway, a stone that reads, in effect, "from here south, the Kiso road." It marks the threshold into the valley that the old travellers feared and the poets praised. Closer at hand, the soba house mentioned earlier serves hand-cut noodles milled from local buckwheat and runs occasional noodle-making sessions by reservation. On the hill behind the town are the earthworks of Motoyama castle, held in the medieval period by a branch of the Kiso clan, and the wooded shrine of Ikeo, whose grove is protected as a local natural monument.

Getting here suits a slow trip. The nearest railway is Hideshio Station on the JR Chuo Main Line, a walk of around twenty to thirty minutes; alternatively, a community bus from Shiojiri Station reaches the Motoyama-shimomachi stop in about half an hour. By car, the site is roughly twenty minutes from the Shiojiri interchange on the Nagano Expressway, heading toward Kiso.
