Shirakaba Onsen is a hot-spring bath in Tomakomai, on the island of Hokkaido. The iron-rich water emerges at 38°C, shared between an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Shirakaba Onsen draws iron-rich waters that tint the bathwater a distinctive amber-brown, a hallmark of Hokkaido's inland hot spring geology. The mineral content is prized for warming the body deeply and easing joint fatigue after a day of outdoor activity. Its birch-grove setting inspired the name Shirakaba, meaning white birch. Pack a towel and enjoy the rustic communal baths at your own pace.
