Misasa Hot Springs have some of the highest radon content in the world. Relations with the home country of the person who discovered radon, Marie Curie, are strong. Because of this, in Misasa there is the Japan-France "Bridge of Love". Located right in the middle of this bridge are the Kajika Frogs, ceramic frogs which are gaining popularity among tourists. The area is an ideal spot for resting and letting off stress.
