沖縄･本島南部 ｜ なぜ高い山が無いのか？ 分厚い堆積層の段丘をバイクで回ろう

The southern part of Okinawa's main island is covered with gently rolling hills. The foundation of this accretionary complex, which dates back approximately 100 million years, was formed into a basin that was depressed by crustal movement. Massive layers of sediment and coral accumulated in this basin, creating the "Uru" (coral) and "Ma" (island). Let's take a motorcycle ride through these terraces and along the coast to experience the fascinating landscape.
