Wariishi Onsen is located in Hida, Gifu prefecture, amid Japan's mountains. The bicarbonate water reaches 40°C and is available across an indoor bath, an open-air rotenburo bath, and a sauna.
Insider tip — Wariishi Onsen, the split-stone spring, emerges in the remote Shokawa headwater valley of Hida City where the granite bedrock of the Northern Japanese Alps fractures in the patterns that give the spring its name. Hida City encompasses the vast Hakusan-Shirakawa-go World Heritage Conservation District where ancient beech forests cover mountain slopes at elevations exceeding 2,000 metres, and the Shokawa-go district preserves gassho-zukuri thatched farmhouses that survived the rigors of five-metre winter snowfall for three centuries.
