Goshiki Hot Springs, meaning 'five-color springs,' is located in Sumoto on Awaji Island, a place of deep historical significance in Japanese mythology as the first land created by the gods Izanagi and Izanami. These chloride-rich thermal waters carry a variety of dissolved minerals that give the springs their characteristic tones and are valued for warming the body, improving circulation, and softening the skin in the Japanese onsen tradition. Awaji Island's position in the Seto Inland Sea and its mild climate make these onsen a year-round destination where therapeutic traditions of Japanese hot spring culture blend with the island's serene natural landscape.
