is a second class airport located west of the city hall in Naha, Okinawa. It is Japan's seventh busiest airport and the primary air terminal for passengers and cargo traveling to and from Okinawa Prefecture, Japan, and handles scheduled international traffic to Taiwan, Hong Kong, South Korea, Thailand, Singapore and mainland China. The airport is also home to Naha Air Base of the Japan Air Self-Defense Force. Naha Airport served 17.5 million passengers in 2014, an increase of roughly three million passengers in two years. History , an Imperial Japanese Navy airfield, opened in 1933. The base was taken over by the United States in 1945 and was renamed . Pan American World Airways and Northwest Orient began service to Naha in 1947. The airport was closed for refurbishment between 1952 and 1954. Japan Airlines began service to Okinawa during this time and initially used Kadena Air Base. Air America operated interisland flights to Miyako and Ishigaki from 1964 to 1967, when Southwest Airlines (now Japan Transocean Air) took over these routes. Okinawa was returned to Japan in 1972. In 1982, Naha Airport was transferred from US military control to the Japan Air Self-Defense Force. The basic and detailed design engineering works in addition to the later construction management phase of the main passenger terminal were awarded in the 1990s in part to the Japan Branch of the American design-build engineering company, The Austin Company, which joined Japanese firms in a joint venture design consortium. Peach, a low-cost carrier based at Kansai International Airport in Osaka, announced that it would establish its second hub at Naha in July 2014, which would initially have flights to Osaka, Fukuoka, Ishigaki and Taipei. ANA Holdings, the parent company of both Peach and Vanilla Air, opened a new LCC terminal in a refurbished portion of the airport's cargo area in October 2012, and plans to open new international facilities in October 2014. Development The airport has been undergoing major development projects that will continue to transform the airport: In 2008, the government agreed to significantly expand the domestic terminal, which will require the relocation of cargo facilities and the international terminal. The construction of a second 2,700m parallel runway began on March 1, 2014 (opening March 26, 2020), on 160 hectares of reclaimed land. The new international terminal opened in February 2014. The international terminal is again being expanded and will grow by 3000m2
