During late June and July in 2015, we tracked the postnesting migrations of 5 loggerhead turtles (Caretta caretta) and 5 green turtles (Chelonia mydas) from a beach on Amami-Oshima Island (Amami) in the Ryukyu Archipelago, Japan, to identify the potential adult foraging grounds of these 2 species of marine turtle. All 5 loggerheads utilized the East China Sea, but 4 took direct paths there while 1 turtle first traveled to and stayed within the Sea of Japan until the water temperature in the area dropped to around 13°C before moving into the East China Sea. In contrast, 3 of the 5 green turtles moved to the coasts of Japan's main islands, 1 green turtle moved to the southwest of the Amami, and 1 green turtle stayed around the Amami throughout the tracking period.
