Roadside station Kuni-no-Matsubara Osaki in Osaki-machi, Kagoshima Prefecture, centers on the combined accommodation and thermal bathing facility Asparu Osaki—a station on National Route 220 where the local community has created a destination offering the full experience of Kagoshima's thermal spring tradition within a roadside infrastructure designed to revitalize rural community life and attract travelers from the Pacific coastal highway. The station is marked by a striking kabutomushi (Japanese rhinoceros beetle) sculpture at its entrance, honoring the area's natural environment where these prized insects are still found in old-growth forest and where they represent the vitality and resilience of the local ecosystem. Travelers who stop here experience both the volcanic thermal bathing tradition of Kagoshima's Osumi Peninsula and the community pride of a roadside station that uses distinctive local symbols to assert its identity against highway homogeneity.
