Hidden within Tanegashima Island, 40 minutes by plane from Kagoshima, plus a 40 minute car drive, there is Chikura Carvern a large opening on the coast of Hamada Beach. Erosion by the sea has made the cave large enough to fit 1000 people. It is only accessable at low tide, so be sure to catch it when you can.
