Nanjō (南城市, Nanjō-shi) is a city located in the southern part of Okinawa Island in Okinawa Prefecture, Japan. Translated literally, the name Nanjō means "southern castle". Many castle ruins, called gusuku in the Okinawan language, can be found throughout the city. The modern city of Nanjō was established on January 1, 2006, from the merger of the town of Sashiki, and the villages of Chinen, Ōzato and Tamagusuku (all from Shimajiri District). Nanjō has an area of 49.69 km² and, on the date of its inception, a population of 41,305, and a density of 831.25 per km².Of the eleven cities in Okinawa Prefecture, Nanjō has the smallest population. It does not have a separate police station nor a high school. For those services, citizens have to refer to the neighbouring towns of Yonabaru and Yaese. The city hosts a fire station responsible for Chinen, Ōzato and Tamagusuku and parts of Yaese, while Sashiki is served by a separate station. The city's main economical activities are agriculture and tourism. Important crops include sugarcane, for sugar and vinegar production, and turmeric, a popular medicinal herb in Okinawa. Several turmeric processing plants are based in the city, producing semi-processed goods to be used by industries on the mainland or consumer products like tea and dietary supplements.

Shimajiri District (島尻郡, Shimajiri-gun, Okinawan: Shimajiri) is a district located in Okinawa Prefecture, Japan.

However, there are hundreds of geographic references throughout Japan and even into the northern Kuriles using "shiri", to approximate the Ainu word shir, meaning island. Despite Okinawa being so far south, historically Jōmon culture was dominant as on the mainland, and words likely have survived, though their original meanings have long been lost or modified. As of 2003, the district has an estimated population of 131,670 and the density of 464.36 persons per km2. The total area is 283.55 km2.
