Yonaguni Island
Underneath the waters off Yonaguni Island, Japan's westernmost point, is an enormous series of ancient stone structures believed to have been a settlement that dates back to 8,000-10,000 BC, which would make it the oldest—by 5,000 years—human structure of this sort. The site has become popular among divers, especially because schools of photogenic hammerhead sharks migrate through the area in winter. Marlin fishing here is also highly rated. Yonaguni Island is also known for the enormous Yonaguni atlas moth, and the wild Yonaguni ponies that roam the blustery cliff tops. To get to Yonaguni Island, you can fly via JAL operated by Ryukyu Air Commuter from Ishigaki Island or Okinawa Main Island.
