United States Army Japan is the Army Component Command of U.S. Forces Japan (USFJ) and is a major subordinate command of U.S. Army, Pacific. United States Army Japan (USARJ) is stationed at Camp Zama, 25 miles southwest of Tokyo. USARJ's history dates from the days of General Douglas MacArthur and parallels the development of modern Japan. Today USARJ is a cost effective key element in upholding the 1960 Treaty of Mutual Cooperation and Security between the United States and Japan, the most important U.S. bilateral relationship in the region and the key to maintaining western Pacific regional stability.
