This building was completed in 1918 as the Ebina Village Office. It was a cutting-edge piece of modern architecture, built in a style known as the county office style. Ebina City then renovated part of the building and opened it in October 1982 as the Ebina City Local History Museum, "Ebina City Onkokan." It has contributed to the development and improvement of local culture by collecting, storing, and exhibiting documents, records, folklore, archaeology, and other materials related to local history. Onkokan opened in 1921 as an "artifact display hall" to coincide with the designation of the remains of Sagami Kokubunji Temple as a historic site. When the Local History Museum opened in 1982, it took over the name and materials.
The first floor displays historical materials (stone tools, earthenware, Kokubunji roofing tiles, etc.), while the second floor has the theme of "clothing, food, and shelter," and displays materials that give insight into the lives of ordinary people from the Meiji, Taisho, and Showa periods, such as household and agricultural tools.
