About 25 minutes by high-speed boat from Ishigaki Island. Kohama Island, located in the center of the Yaeyama Islands, overlooks the azure blue waters of Sekisei lagoon, one of the world's largest coral reefs. You can experience the charm of the beach and the sea and spend a luxurious vacation on the remote island enjoying marine activities, Ryukyu spa, and golf. This is what only a beach resort on a remote Okinawan island scattered with private villas can offer.
