Hot Spring & Bath Information

Futamata Calcium Hot Spring (Artificial Hot Spring)

TypeArtificial Hot Spring

An artificial hot spring that dissolves the mineral deposits from Futamata Onsen in Oshamambe, Hokkaido. It enhances the bathing effect to promote blood circulation, warming the body to the core and providing a bath experience that retains heat well. Despite being an urban capsule hotel, it combines hot spring ambiance with high heat retention, making it a 'signature bath'.

A self-löyly system where you pour a ladle of aromatic water onto sauna stones, instantly raising the perceived temperature with rising steam. The steam fills the room, creating a heat curtain, allowing you to customize your preferred heat and humidity range with changing aromas. This 'customizable' sauna allows you to create peaks of humid heat at short intervals.

Equipped with a Bonatherm heater under the bench for even heating, it automatically adds water to aromatic stones to generate steam. This sauna reduces the dry sensation that can irritate the nose and throat, enveloping you in heat and humidity to induce deep sweating. Its air design minimizes heat unevenness, making it a 'core' sauna where you can sweat effectively from the beginning of your stay.
