SodiumChloruresBrome
Marukoma Onsen sits on the shore of Lake Shikotsu, in Chitose, Hokkaido. Sodium-chloride water surfaces at 42°C, shared between an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Marukoma Onsen is one of Hokkaido's most dramatically situated lakeside ryokan, with outdoor baths extending directly to the crystal-clear shoreline of Shikotsu Lake — one of Japan's deepest and clearest caldera lakes; soaking in mineral spring water while watching mist rise from Japan's northernmost ice-free lake creates an experience of almost surreal natural beauty.
