Higashiura Spa Awaji is a coastal hot spring and wellness facility in Awaji City on Awaji Island, Hyogo Prefecture, Japan, the largest island in the Seto Inland Sea and the island that, according to the creation myth of the Kojiki — Japan's oldest chronicle — was the very first island created by the deities Izanagi and Izanami, making Awaji cosmologically the birthplace of the Japanese archipelago itself. The naturally chloride-sodium spring waters here carry the distinctive saline mineral character of the Seto Inland Sea coastal zone, valued for their deeply warming, circulation-stimulating, and skin-moisturizing properties that complement the island's marine atmosphere and proximity to the famously fast tidal currents of the Naruto Strait. Bathing in the thermal mineral waters of Japan's mythological 'first island,' surrounded by the extraordinary Seto Inland Sea scenery and the fresh seafood culture of Awaji's fishing villages, provides a uniquely cosmologically resonant hot spring experience.

Insider tip — Higashiura Spa sits on the eastern shore of Awaji Island, drawing mild sodium-chloride water at 38°C with panoramic views across the Osaka Bay. The gentle temperature suits extended soaking, and the coastal breeze keeps the outdoor baths refreshing even in summer. Access from Kobe via the Akashi Kaikyo Bridge makes this a popular half-day escape from the city.
