Nanae Tennen Onsen, known as Yuhi no Yakata, is set in Nanae, on the island of Hokkaido. Sodium-chloride water reaches 42°C, feeding an indoor bath and an outdoor rotenburo, with an on-site sauna.
Insider tip — Yuhi no Yakata, the hall of the setting sun, stands in Nanae-cho just north of Hakodate. From outdoor baths you can watch the sun sink into the Tsugaru Strait, and the coastal sodium-chloride water warms the body in Hokkaido winters.
