Insider tip — At Japan's southernmost point on Honshu where the Pacific Ocean meets the Kumano Coast, this princess spring (Hime Onsen) and its Kobo no Yu (waters of Saint Kobo) honor the pilgrim legacy of Kukai who walked the entire Kii Peninsula founding sacred sites; Kushimoto's dramatic Hashiguiiwa rock formations rising from the sea are visible from the coastal bathing terrace.
