Xibiao Island is a seriously underestimated island. Although it belongs to the outlying island of Ishigaki, it is bigger than Ishigaki Island. The area of the island above 90 % is the original rainforest, known as the last pure land of Japan. We stayed here for 2 days and rented a car. Basically, the whole island has a road to visit (there is no road in the southwest of the island is the original rain forest). In addition to the two ports of Dayuangang and Shangyuangang, no one is seen in other places. You can enter the rain forest by boat from Punechuan and explore no man's land on foot.
