Your hotel in Ibusuki overlooks Kagoshima bay. It is the perfect location to enjoy a sand bath, a unique experience in Japan where you are buried to your head in sand (don't worry, you can get out anytime!) which is naturally heated from the ground. You emerge feeling like a new-born and can then proceed to the normal hot springs to wash off and relax.
