Naha (Ryukyu: ナーフフ) is located on the west coast of southern Okinawa, where the county seat of Okinawa Prefecture is located and the largest city on the Ryukyu Islands. Now it is the political and economic center of Okinawa Prefecture. The capital of the ancient Ryukyu Kingdom is located in the eastern suburb of the city.

Naha is the smallest of all prefectures and counties in Japan, and it is also the city with the highest population density in Japan, even higher than Nagoya, the city designated by the law. Due to the development of tourism in Okinawa in recent years, the International Street in the urban area and Ryukyu Village in the suburbs have become the most famous scenic spots in Naha.

The US military has returned the residential land in the north of the city on 1987, and is now developing into the new capital of Naha. From June 5438 to February 2004, the world's largest DFS duty-free shop opened here.
