Ishigaki Island is located about 400km southwest of Okinawa Prefecture's main island, surrounded by a sea of coral reefs. 50,000 people live on the island. Once, many came to the island in search of a new frontier across the ocean. Life on the island is built by a mix of people of various histories and cultures. Facing one rough wave after another, life on Ishigaki Island is inherited from one generation to the next.
