Aji Onsen

A simple weak radioactive cold mineral spring (radon spring) that bubbles up from deep underground bedrock on the Ajihanto Peninsula. It is characterized by an exceptionally smooth and soft feel, with strong bathing benefits and moisturizing properties that help keep you from cooling off after your bath. At the Heike no Yu open-air bath, which offers a panoramic view of the Seto Inland Sea, and the atmospheric Genji no Yu rock bath, you can enjoy a blissful soak together with the scent of the sea breeze.
