A spacious indoor bath where you can fully unwind from your travel fatigue in a relaxed setting. Here, you can luxuriate in a fossil seawater hot spring, where ancient seawater from 300,000 years ago bubbles up from the ground, enjoyed as lavish natural free-flowing spring water. Its extremely high salt content gives the water a feel reminiscent of natural thalassotherapy, or marine therapy. The hot spring is known for its outstanding heat retention and moisturizing effects, and the warmth lingers long after you leave the bath.

A unique open-air bath shaped like a ship, designed in homage to the history of the Ando navy, which was active in medieval times. Precious fossil seawater hot spring water bubbling up on the grounds is poured in freely, and the bath is divided into a hot bath and a meditation foot bath lined with small stones. You can soak while feeling the pleasant massage effect on the soles of your feet, let the sea breeze brush your cheeks, and at night gaze up at a clear, star-filled sky for a deeply restorative experience.

A luxurious private open-air bath with natural free-flowing spring water, available in special rooms such as Yukurabito Club, with some rooms offering a semi-open-air style. This is a supreme space where you can enjoy the ancient seawater hot spring whenever you like, for as long as you like, without anyone disturbing you. Some rooms are designed to be barrier-free, allowing everyone to enjoy the famous waters with peace of mind. Soak quietly in the bath and enjoy an exceptional private stay filled with the clean air of the Sea of Japan coast and a gentle sense of time.
