Miyoshi Onsen is situated in Miyoshi City, Hiroshima Prefecture, a gateway city to the Chugoku Mountains where the scenic Tojo region offers some of Hiroshima Prefecture's most beautiful mountain landscapes including the Tojo Highland and Nishichugoku Sanchi Quasi-National Park. The siliceous thermal waters here provide a warm retreat in a highland city that serves as a base for exploring Hiroshima's mountainous interior — far from the well-trodden coastal and peace memorial tourist circuit. This onsen represents the quieter, mountain-centric side of Hiroshima cultural life, where thermal bathing traditions continue in a scenic and unpretentious highland community setting.
Insider tip — Miyoshi sits in the heart of Hiroshima's mountainous interior where the Gono River and its tributaries carve deep valleys. The onsen facility here offers bicarbonate waters prized for improving circulation and softening skin. The surrounding Nishichugoku Sanchi Quasi-National Park makes this a fine base for hikers and nature lovers.
