Kushimoto, at the southernmost tip of Honshu island in Wakayama Prefecture, is renowned for the magnificent Hashigui-iwa rock formation and Cape Shiono, where the Pacific Ocean meets the Kumano Sea in some of the most dramatic open-ocean coastal scenery in Japan. Kushimoto Onsen Misaki draws on chloride-rich coastal thermal waters that reflect the maritime character of this remote cape town, offering warming baths with the atmosphere of a lighthouse spa at the very edge of Japan's main island. The Kushimoto Marine Park, with its vibrant coral reefs and glass-bottomed boat tours, and the historic Ertugrul Ottoman frigate shipwreck site add remarkable depth to any visit to this southernmost corner of Honshu.
Insider tip — Kushimoto Misaki Onsen sits at the southernmost tip of Honshu where the Kii Peninsula meets the Pacific, giving ocean-view baths a genuine sense of being at lands end. The bicarbonate spring water is mild and clear, contrasting with the wild rocky coastline and the famous Hashigui-iwa bridge-pillar rock formation just minutes away. The offshore Okinoshima island visible from some baths adds a meditative backdrop to the soak.
