Head to one of Ishigaki's most stunning spots — Hamajima Island, or "Phantom Island," is a crescent of pure-white sand that only peeks above the waves at low tide. With your guide, you'll first land on the island and enjoy 360º views of the gorgeous blue ocean. You'll feel like you're walking on the sea itself! Then it's time to dip below the waves as you snorkel on one of Japan's largest coral reefs. Look out for colorful fish and sea turtles as you swim through crystal-clear waters.
