Kohama-jima with Iriomote-jima in the background.

Kohama-jima is a real small island just between Ishigaki-jima and Iriomote-jima (in the background is Iriomotejima with Yubu-jima just before it). The island is small enough to ride a moped around in about an hour. We rented this little white car it was perfect, even though it had rust holes everywhere and a rattling muffler.
