A seaside inn where you can enjoy panoramic open-air baths overlooking the Pacific Ocean and a full-fledged rooftop sauna with self-löyly
Chiba Kamogawa City
Houraiya is a hot spring ryokan in Kamogawa City, Chiba Prefecture, known for its specialty Kinmedai dishes. From the panoramic open-air baths Hissui and Benihi on the rooftop, you can take in sweeping views of the Pacific Ocean and enjoy the beautiful changing scenery of the sea and sky throughout the day. The open-air area is also equipped with a log-cabin-style rooftop sauna, where you can enjoy the best outdoor bathing experience while being wrapped in your preferred steam with self-löyly and refreshed by the sea breeze. The baths use a mildly alkaline natural hot spring, sodium chloride spring, that warms you from the inside out. Private open-air baths, where you can fully enjoy the spectacular view in complete privacy, are also popular.

It is subject to a morning-evening gender swap, so you can warm up while soaking in a variety of spectacular views, including the sparkle of the morning sun and the beautiful gradients of dusk.
