Naha is city and capital of Okinawa ken (prefecture), Japan. It lies on southwestern Okinawa Island, which is one of the Ryukyu Islands. Long the chief city of the archipelago, it contains the Sogen Temple, burial place of the rulers of the early Okinawa kingdom. The Shurei Gate is a fine example of Ryukyuan architecture. Naha was the seat of the post-World War II U.S. military and Okinawan governments and became the prefecture capital in 1972. Because of its deepwater port, Naha is the commercial centre of the Ryukyu Islands chain. Traditional handicraft industries produce porcelain, lacquer ware, dyed cloth, and the potent awamori liquor. The city is also the seat of the University of the Ryukyus (1950).
