Since World War II Onna has been a small-scale center of sugarcane production but tourists from mainland Japan, China, Taiwan, S. Korea, Australia and many other countries stay in one of the many seaside resorts that have been built just before, and after, the beginning of the new millennium. In recent years pineapples and mikan, or satsuma mandarin, have been grown in the rugged hill areas of the village. Like other municipalities on Okinawa Island, cut flowers and greenhouse vegetables intended for the Japanese homelands have become important agricultural products.
