Shigira Ogon Onsen Shigira Seven Miles Resort

Hot springs on Miyakojima (宮古島), already rare in Okinawa, at this large resort. There are open-air baths, a cave bath, and a swimsuit-required mixed pool zone for those who want to soak together without the traditional onsen setup. The regular indoor and outdoor baths are gender-separated. The resort is big and the onsen is one amenity among many; reviews suggest the facilities are a bit worn and the service uneven.
