A 1939 Inn Built to Catch the Eye
The main building of Ryokan Yonemoto stands at the center of its plot on a street in Kaminoyama Onsen, a hot-spring town in the city of Kaminoyama, Yamagata Prefecture. Completed in 1939, the wooden two-story structure covers about 178 square meters and carries a hipped roof clad in sheet iron.
What sets it apart is the front. Mortar-rendered walls are scored to suggest shallow pilasters; the western corner has been cut away and reworked into Doric-style columns; round windows are set into the upper floor; and a separate entrance porch on the south side wears a tiled hip-and-gable roof in the Japanese manner. The combination is deliberate and a little playful, and it is this inventive facade that earned the building a place on the national register.
Why a Hot-Spring Inn Joined the National Register
Japan protects historic buildings through two separate systems, and the distinction matters here. The older route is "designation" (shitei), which singles out the most important structures as Important Cultural Properties or National Treasures and places them under strict controls. The newer route is "registration" (toroku), introduced in 1996 to safeguard a far wider range of relatively recent buildings, often those more than fifty years old, while letting owners keep using them in daily life.
Ryokan Yonemoto belongs to this second category. It was added to the register of Tangible Cultural Properties on 28 October 2011, under registration number 06-0128. The criterion cited for it is plain: the building contributes to the historic character of its surroundings. Its worth lies less in rarity than in the way its facade shapes a working onsen street. Inns of the late 1930s often borrowed Western classical detailing to signal that they were modern, and the chamfered corner with its Doric columns does exactly that, while the hip-and-gable entrance keeps the design rooted in Japanese tradition.
What to Look For
Read the front from the corner first. The western angle has been sliced off and turned into a pair of column-like forms in the Doric idiom, a small classical flourish on what is otherwise a timber inn. Lift your gaze and the second floor answers with round windows, an unusual choice that lightens the wall and gives the upper story a rhythm of its own. The mortar render, ruled to imitate pilasters, ties the whole face together. The south side carries the entrance under a tiled hip-and-gable roof that reads as unmistakably Japanese.
The building sits among the inns and bathhouses of Kaminoyama Onsen, so the rewarding way to see it is on foot, as part of a slow walk through the spa quarter. The property is privately held and its interior is not arranged for general sightseeing, so plan to appreciate the exterior from the public street. Check directly with the establishment or the local tourist office about current operation before counting on a stay or a look inside.
Around Kaminoyama Onsen
Kaminoyama has drawn bathers for centuries. Local accounts trace the spring's discovery to the fifteenth century, and by the Edo period the town prospered twice over, as the castle town of the Kaminoyama domain and as a post station on the Ushu Kaido highway. That double identity is still legible today. A short walk brings you to the reconstructed keep of Kaminoyama Castle, which looks toward the Zao mountains, and the streets are dotted with public bathhouses, foot baths, and inns that welcome day visitors for a soak.
The area has also reinvented itself as a place for walking. Kaminoyama holds the only health-walking courses in Japan certified on the German "Kurort" model, threading through orchards and vineyards on the hillsides above the town. The local wineries reward a detour, and the tourist office near the station pours tastings of Kaminoyama wine.

Q&A
- Can I stay overnight at Ryokan Yonemoto?
- The building is privately owned and its status as a working inn can change over time, so confirm current operation and bookings with the establishment or the Kaminoyama tourist office before you travel. The cultural-property listing covers the historic building itself, not a guarantee of guest service.
- What is a "Registered Tangible Cultural Property"?
- It is a building or object entered on a national register under a system begun in 1996. Registration is a lighter form of protection than designation. It targets relatively recent structures and is designed to keep them in everyday use while preserving their character.
- When was the building constructed?
- In 1939, the fourteenth year of the Showa era. It was added to the national register on 28 October 2011.
- What makes the architecture unusual?
- The eclectic front. A chamfered corner with Doric-style columns and round upper-floor windows borrow from Western classicism, while the hip-and-gable entrance porch stays firmly Japanese. The mortar walls are scored to imitate pilasters.
- How do I reach Kaminoyama Onsen?
- Take the JR Ou Main Line to Kaminoyama-Onsen Station. By car it is about ten minutes from the Kaminoyama-Onsen or Yamagata-Kaminoyama interchange on the Tohoku-Chuo Expressway, and roughly forty-five minutes from Yamagata Airport.
