During the American occupation of Japan following World War II, a United States Army base, Camp Haugen, was located in Hachinohe, and was the home of the Seventh Division. An Armed Forces Radio Service radio station was located on the base; it was known as AFRS Hachinohe. In 1950, after the North Korean invasion of South Korea, troops from Camp Haugen left for Korea. AFRS Hachinohe altered its broadcasts to include coverage of South Korea so Americans could benefit from its news and entertainment programs. With the final withdrawal of American forces from Hachinohe in 1956, the base was turned over to the Japan Ground Self-Defense Force and was officially re-designated JGSDF Camp Hachinohe.
