Inunakisan Onsen Yama no Yu, nestled in Izumisano, Osaka prefecture, features sulfurous water at 42°C, pH 6.5. An indoor bath, an outdoor rotenburo bath and a sauna round out the facility.
Insider tip — Inunakisan, the dog-crying mountain, hides a sacred valley of temples and sulfurous hot springs deep in the forested hills above Izumisano, just inland from Kansai Airport. The mountain trail between shrine gates and waterfall pools has been a pilgrimage route since the 8th century — a remarkable contrast to the nearby runways.
