Minamiawaji Onsen

Minamiawaji Onsen is a thermal resort in Minamiawaji city on the southern tip of Awaji Island in Hyogo Prefecture, Japan — the large island in the Seto Inland Sea that connects the Kii Peninsula to Shikoku by the Great Naruto Bridge and Akashi Kaikyo Bridge, famous in Japanese mythology as the first land created by the creator deities Izanagi and Izanami. The siliceous geothermal waters here draw from the volcanic and sedimentary geology of the Naruto Strait region, offering restorative bathing with views across the famous whirlpools of Naruto — one of the world's largest tidal whirlpool formations, reaching diameters of up to 20 meters during spring tides. The mythological, natural, and culinary significance of Awaji Island — renowned for its Kobe beef, fresh seafood, onion production, and its role as the birthplace of Japanese civilization according to the Kojiki — makes Minamiawaji Onsen a thermal destination of extraordinary cultural and cosmological resonance.
