Ishigaki Island

Ishigaki Island is the commercial hub of the Yaeyama Islands, in Japan’s southwestern Okinawa Prefecture. It’s known for beaches and sites for snorkeling, diving and surfing. Within Iriomote-Ishigaki National Park lies the Shiraho Reef’s rare blue coral. In the interior is Mt. Omoto and other peaks. On the northern Hirakubo Peninsula is the Fukido River, a mangrove forest habitat. wikipedia
