Ishigaki, Okinawa

While it is the largest island in the Yaeyama archipelago, Ishigaki is small enough to traverse in about an hour, giving visitors ample time to explore its tropical beauty. One of the island's most famous attractions is Kabira Bay, renowned for its emerald waters and white sand beaches. Glass-bottom boat tours offer an up-close look at the bay’s colorful coral reefs and tropical marine life.
