According to a local newspaper, a loggerhead turtle laid eggs in the daytime at Tokubama Beach on Kakeroma Island. Cautious sea turtles usually lay eggs at night, so this must be a very rare occurrence.

In Amami, sea turtles are supposed to lay eggs from June to July.
I watched a loggerhead turtle laying eggs for the first time last June, on a beach facing the East China Sea in Tatsugo-cho. Around ten p.m. a loggerhead crept up the sandy beach about twenty meters. Then she dug the sand tentatively here and there, as if to find if it was a right place for her. Finally she started to dig a hole deep enough to lay eggs. After twenty or thirty minutes she filled in the hole. To my big surprise,
she started digging another hole nearby, but she soon filled it with the sand. She repeated this behavior several times. After a while, no one could tell where she originally laid eggs. I was impressed by this wondrous behavior which surely has to be imprinted on her DNA.

Then she returned to the sea again. The whole procedure took her about two hours. Incidentally, the newspaper reported the turtle at Tokubama Beach laid about eighty eggs.
