Oshirakawa Onsen Shiramizu no Yu is located in Shirakawa, Gifu Prefecture. Its bicarbonate water, at 40°C, fills an indoor bath and an outdoor rotenburo, with a sauna also available.
Insider tip — Shiramizu no Yu, the white water spring, sits in Shirakawa-mura — the UNESCO World Heritage village famous for its gassho-zukuri farmhouses, whose steep thatched roofs angled like praying hands shed the 3-metre annual snowfall of Japan heaviest snowfall zone. The Sho River that carved this valley runs glacier-milky white from the Hakusan highland snowfields, giving the spring and the village their shared imagery of purity and whiteness.
