Shobara Onsen is located in Shobara City, Hiroshima Prefecture, in the elevated Chugoku Mountain interior where the city's history as a center of the Bingo Province's northern highland culture is preserved in castle ruins and local historical museums. The siliceous thermal waters here serve a mountainous inland city whose cool highland climate and forested landscapes create a refreshing alternative to the coastal Hiroshima lowlands. These onsen invite visitors to discover a lesser-known dimension of Hiroshima Prefecture beyond the famous peace memorial city — a world of mountain villages, ancient provincial administration history, and rural thermal bathing culture.

Insider tip — Shobara occupies a highland basin in northern Hiroshima Prefecture, surrounded by forested Chugoku mountains and clear river valleys. The onsen waters here are mildly bicarbonate and cool enough year-round to be refreshing even in summer heat. The surrounding countryside is known for buckwheat fields and autumn foliage that frames the open-air baths.
