In Sotogahama, Aomori Prefecture, Yu no Sawa Onsen Chaporatto heats sodium-chloride water to 41°C. An indoor bath, outdoor rotenburo and sauna are available on site.
Insider tip — Chaporatto means something that splashes happily, and the spring at Sotogahama captures the lively energy of a village perched at the northern tip of Honshu facing the Tsugaru Strait. On clear days Hokkaido is plainly visible across the water, and the wind and tides here carry the maritime atmosphere of the Seikan connection.
