Yahoo!トラベルユー... 5/19/2026The Onsen offers different mineral qualities between the indoor bath and the open-air bath. The open-air bath feels wonderfully spacious, and on the ocean side you can soak while watching the hot spring water gush out. My body, which had been crying out in pain, felt restored. Thank you very much.
