Naha International Airport (OKA/ROAH) serves as the primary aviation hub for Okinawa Prefecture, Japan's southernmost prefecture. Located on the western coast of Okinawa's main island adjacent to the city of Naha, it handles both domestic and international passenger traffic as well as significant cargo operations. The airport plays a critical strategic role in the region, sharing its runway with Japan Air Self-Defense Force (JASDF) Naha Air Base. It is one of the busiest airports in Japan by passenger throughput, serving millions of travelers annually drawn to Okinawa's tourism industry. A major expansion added a second runway, which opened in 2020, significantly increasing capacity. The airport serves as a hub for Ryukyu Air Commuter and a key base for Japan's low-cost carriers operating routes throughout Japan and to nearby East Asian destinations including Taiwan, South Korea, and China.
