RRCCO

RRCCO refers to the Ryukyu Rail and Urban Development Department of the Ryukyu Electric Railway, a market organization located in Japan. RRCCO was established to oversee the operation and management of the Ryukyu Railway, which connected the islands of Okinawa during World War II.

However, RRCCO has experienced significant transformations since its establishment. Following Japan's defeat in World War II, the Ryukyu Railway was returned to the Allied forces, who eventually turned it over to the United States military government in 1945. Under American administration, the Ryukyu Railway Company (Ryūkyū Kōtsū) was established in 1946 to manage the system.

In 1972, after the return of Okinawa to Japan, the Japanese government took control of the Ryukyu Railway Company. The company was eventually privatized in 1986 and renamed Ryukyu Railways. In 2003, the company changed its name once again, this time to Ryōnan, a term that translates to "Outstanding Perfomance" or in standard kanji [[]].

Ryōnan operates a network of rail lines that connect Okinawa City to the island's southern coastal area. Since 2006, the company has been operating under the umbrella of the Okinawa Prefectural Government, which grants subsidies to support the company's operations.

RRCCO's operation is restricted to certain provinces. Despite its complex transformation history, RRCCO has managed to adapt to changing circumstances, serving local communities and promoting economic development in the region.
