By the time we got to Kojima Island, it was well into the afternoon. A boat pulled up soon after and after a quick exchange with the driver, we hopped aboard. He first took us to a small beach where he stopped the engine and rattled off in Japanese. I didn't catch all of it, but it had something to do with it being in shadow at that time of day. Just as soon as we had stopped we were off again and he pulled up against a section of rocks jutting out into the sea.
