Introduction to Hiraiuchi Kaichu Hot Spring: Hiraiuchi Kaichu Hot Spring is located on the south side of Yakushima. When the tide is high, this hot spring is hidden in the coastline of the Pacific Ocean and is no different from other coastlines. During the two hours before and after the seawater ebbs, several holes will appear in the rocks on the shore, and the hot springs gushing from the ground will fill them up, becoming a famous local open-air mixed-sex bathing hot spring.
