Kashikojima Onsen sits on Kashikojima, a small island in Shima, Mie Prefecture, looking out over the intricate inlets and scattered islets of Ago Bay. The setting is very much part of its appeal: this is the heart of Ise-Shima National Park, where the landscape shifts between quiet coves, pine-fringed shores, and broad water views that change with the light.
Compared with Japan’s older hot spring towns, Kashikojima Onsen feels more closely tied to the sea than to a traditional onsen street. It works well as a calm base for exploring the wider Ise-Shima area, whether that means taking in the bay scenery, visiting nearby Shima sights, or simply slowing down and enjoying one of Japan’s most distinctive coastal landscapes.
