A historic hot spring destination nestled in the mountains in northwestern Hyogo Prefecture, with a history dating back to the Heian period. At the heart of the hot spring town, the 98-degree source, Arayu, one of the hottest in Japan, sends up plumes of steam with great force, and the local tradition of boiling eggs and vegetables brought by visitors in the hot spring water—known as yukagi culture—still lives on today. The nostalgic Showa-era atmosphere that drifts through the hot spring town, combined with the experience of Arayu, where you can feel the energy of the earth directly, makes this an extremely unique and appealing onsen destination for foreign travelers who want to experience deep local Japanese culture.
