An indoor public bath that draws from multiple private spring sources, including Hshiriyu, one of Japan's three great ancient hot springs. Through the large windows stretching across the front, you can look out over the beautiful blue waters of Sagami Bay, creating an overwhelming sense of openness as if you were soaking in the sea itself. The hot spring water contains salt and abundant minerals, providing excellent heat-retention effects and helping relieve cold sensitivity and fatigue.

Three private open-air baths with different atmospheres on the rooftop. If available, you can enjoy a private soak as many times as you like for free. A vast panoramic view of Sagami Bay stretches out before you, and the sunrise over the horizon and the star-filled night sky are breathtakingly beautiful. The isotonic chloride spring is gentle on the skin and warms you thoroughly from the core of your body.
