In 1990, the total population of Okinawa Island was an estimated 1.22 million people, comprising Ryūkyūans (especially native Okinawans), Japanese people, and expatriates, as well as American military personnel and their families.
Whereas northern Okinawa Island is largely unpopulated, the south is markedly urbanized—particularly the city of Naha, and the urban corridor stretching north from there to the city of Okinawa. The island also houses six gusuku, Okinawan fortresses most of which now lie in a state of ruin.
The southern end of the island consists of uplifted coral reef, whereas the northern half has proportionally more igneous rock. The easily eroded limestone of the south has many caves, the most famous of which is Gyokusendō in Nanjō. An 850 m stretch is open to tourists.
