A panoramic public bath overlooking the calm sea of Ago Bay and the lush islands beyond through large glass windows. The hot spring uses the mild Hamajima Onsen, which blends gently with the skin. Because it contains salt, it has excellent heat-retention properties and warms you slowly from the core. At night, enjoy a luxurious bath while gazing at the star-filled sky, and in the early morning, admire the beautiful sunrise rising from the horizon.

An open-air bath with spectacular views located right by the sea, surrounded by the refreshing scent of the ocean and the sound of the waves. On the women’s side, there is a semi-open-air bath, while on the men’s side there is a scenic wooden deck for cooling down after the sauna. You can fully enjoy a luxurious outdoor air bath while feeling the gentle sea breeze that sweeps through Ago Bay.
