Miyagawa Onsen is set in Hida, Gifu Prefecture, a mountainous area of the Japanese Alps known for its traditional villages. Sulfurous water rises at 44°C, feeding an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — Miyagawa Onsen occupies the Hida highlands along the Miyagawa River, one of the most scenic valleys in Gifu Prefecture. Sulfurous waters emerge from volcanic fissures in the mountains and are channelled directly into simple open-air baths with views of the forested gorge. The onsen town sits on the route to Shirakawa-go, making it an ideal overnight stop for heritage village visitors. Snow monkeys from the surrounding forest are occasionally spotted near the river in winter.
