Hokkaido Hakodate City
An inn of natural onsen fed straight from the source and superb seafood breakfasts
OMO5 Hakodate by Hoshino Resorts is an inn for enjoying everything Hakodate has to offer. Its onsen, Kohakuiro-no-Yu, is filled with a reddish-brown, iron-rich strong sodium chloride spring fed straight from the source, never recirculated, and it warms you to the core. With both a dry sauna and a mist sauna, it offers a deep refresh for body and mind. After your bath, unwind in OMO Base, bathed in light from stained glass and the notes of a hand-cranked organ, and the next morning, savor a superb breakfast buffet of port-town specialties such as seafood rice bowls and flame-seared dishes.

A strong sodium chloride spring rich in iron, glowing a mysterious reddish brown. Fed straight from the source, never recirculated, the dense water gently envelops you and warms you to the core. It holds heat well, so you stay warm long after bathing, and you can enjoy a superb soak in a variety of baths: a spacious indoor bath, an open-air bath under an arbor-style roof with the warmth of wood, and ceramic urn baths where you can relax on your own.

A proper dry sauna that gets you sweating in earnest. In a clean, comfortable space you can sweat freely and feel a detox effect from within. Alternating between the heat and the cold plunge right next to it makes for a deeply refreshing experience that eases the fatigue of travel.

A mist sauna where a fine mist wraps around your whole body. Even those who find the heat of the dry sauna too much can warm up comfortably, and the moist air gently settles both body and mind.
