Komorebi Onsen is located in Hakodate, a port city in southern Hokkaido. The iron-rich water flows at 41°C, pH 6.3. The facility offers an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Komorebi Onsen draws iron-rich spring water in the southern Hokkaido landscape near the Tsugaru Strait. The copper-tinted bath is especially appreciated in winter, when Hokkaido's bitter cold makes the warming mineral soak a welcome pleasure. Light filtering through surrounding birch trees gives the outdoor bath its name — 'komorebi' meaning dappled sunlight in Japanese. The unhurried atmosphere and absence of tourist crowds make this a genuine local retreat.
