Sea area of southern Iriomote-jima Among the Yaeyama Islands, this sea area supports the greatest number of green turtle Chelonia mydas, which is known to feed on seagrass beds developed in the head of the bay endowed with nature. The south shores of Iriomote-jima (island), especially beaches known as Takahama and Wakarehama are the highest density spawning grounds of green turtle Chelonia mydas in the Nansei Islands. As there are no roads and villages in the vicinity, the areas are well endowed with nature. Reef flats extend far in the offing.
