Sunamushi Kaikan Saraku is a facility where visitors can enjoy both a sento public bath and sauna as well as Sunamushi Onsen, a natural onsen located right on the coast. This onsen is actually the only place in the world where visitors can try out sunaba sand baths. Known around the world as a Japanese-style sauna, bathing in Sunamushi Onsen is said to heal both mind and body through the weight and warmth of the sand alongside the sound of the waves nearby. It is also said to have positive effects on the body, such as increasing blood circulation and clearing toxins from the skin. Sunamushi Kaikan Saraku is a great spot for travelers to relax in the sun and release some stress during their journey.
