Amami Oshima (Naze), Japan cruise port guide

Amami Oshima is something of an enigma for historians. No one can accurately place its age: stone tools suggest habitation as early as the Japanese Paleolithic period (pre-10,000 BC), while other artefacts, including pottery, indicate human presence much later, from the bronze age onwards. Great clumps of the sub-tropical cycad plant — one of the oldest surviving species in the world, said to be over 250 million years old — cover the island in profusion, immediately conjuring up images of dinosaurs chomping on the enormous leaves.
