Uruma Island-Connecting Scenic Drive: Katsuren Castle Ruins and Kaichū Dōro (海中道路)

A scenic driving course through Uruma City in central Okinawa Main Island, where you visit UNESCO World Heritage sites and islands connected by bridges in a single day. Start by morning at Katsuren Castle Ruins (勝連城跡), with its gracefully layered curved stone walls on a hillside. From the summit, gaze over Kin Bay and the marine road highway ahead, then exhilarate in the straight 4.7 km drive across the sea. At Sea Station Ayahashi-kan (海の駅あやはし館) midway, lunch on the local specialty: mozuku soba and tempura. In the afternoon, cross to Hamahiga Island (浜比嘉島) and visit Shirumichū (シルミチュー), the sacred site connected to Ryukyu's founding deity, where quiet prayers still resonate. The grand finale: Kahō Banta (果報バンタ) on Miyagi Island's heights—the "Fortunate Cape" overlooking emerald seas—plus a salt factory tour. Experience a full day immersed in Uruma's island time.
