KSBK (AM)

KSBK (880 AM) was a radio station in Naha, Okinawa, Ryukyu Islands, Japan, operated by the Ryukyu Broadcasting Corporation (RBC). At its closure, it was the only non-military English-language radio station in Japan; among the disc jockeys who worked at the station were Robert Colbert and Art Bell. KSBK, which became JORO when the Ryukyu Islands reverted to Japan in 1972, operated from September 1, 1955, to October 31, 1973, being closed as a result of government skepticism over the continued need for a commercial English-language station and the application of Japanese broadcasting regulation, which did not permit duopolies.
