Art Deco, which originated in France in the 1920s and 1930s and flourished in the United States, replaced Art Nouveau, an artistic movement that flourished in Europe from the late 19th to the early 20th century.

It is estimated that the first and second floors were built in the Taisho era (1912-1926) and the third floor in the early Showa era (1926-1989).

In the past, many of the buildings in Ginzan Onsen were constructed or restored using timber from their own backyards. This resulted in a unique landscape where different styles from different eras coexisted in the buildings that had been built over the years.
The renovation of the “Honkan Koseki-ya” was carried out by reusing old materials as much as possible and using traditional Japanese woodworking techniques to recreate the original appearance. The use of new materials was unavoidable, but the coloring was left as it was to respect the character of the local building and the taste that time has fostered.
