Kanagawa Yokosuka City
A spectacular open-air bath with sweeping views of Tokyo Bay and blissful outdoor air bathing in the sea breeze
"Yokosuka Onsen Yurak no Sato" is a day-use hot spring facility located along the Maborikaigan coastline in Yokosuka City, Kanagawa Prefecture, and is known for its stunning ocean view. In the observatory open-air bath, where you can soak while gazing at the breathtaking panorama of Tokyo Bay spread out before you, you can fully enjoy a sodium-iodide-chloride strong saline spring that wells up from underground. Rich in salt, the water has excellent heat-retaining properties and warms the body from the core. The sauna area includes two types: a high-temperature dry sauna that delivers intense heat, and a gentle salt sauna that is kind to the skin. After cooling down in the cold plunge bath, you can enjoy outdoor air bathing on the terrace, where the sea breeze blows pleasantly through, and experience an exceptional state of relaxation in a resort-like sense of openness.
