Kanagawa Hakone Town, Ashigarashimo District
"Tenseien" is a hot spring hotel in Hakone-machi, Ashigarashimo-gun, Kanagawa Prefecture. Located in Hakone Yumoto, it owns four abundant natural hot spring sources on its grounds. From the "Tenku Dai Rotenburo" on the top floor of the building, guests can enjoy a sweeping sense of openness and magnificent seasonal views of Hakone while fully savoring its skin-beautifying waters. The sauna area features two types of sauna: an authentic dry sauna and a low-temperature mist sauna that gently moisturizes hair and skin. A spacious cold plunge bath is set right in front of the dry sauna. With private baths and a garden where Tamadare Falls stands, there are many attractive facilities to enjoy.

TypeNatural Hot Spring
A bright and spacious indoor bath with warm sunlight streaming in through large windows. There are two large bathtubs where you can stretch out and relax at ease, and you can sink your shoulders into the colorless, clear, skin-smoothing hot spring water and gently unwind daily stiffness and fatigue from your body.
