The 35th Supply & Service Battalion is headquartered at Sagami General Depot. Its mission is to maintain Army prepositioned and Operational Project Stocks for all classes of supply except ammunition. The value of installation and war reserve stocks on hand is approximately $300 million. Critical prepositioned stocks and equipment are stored at the depot for use by USARJ & 9th TSC subordinate commands and U.S. forces that might deploy to Japan, as well as stocks able to be provided to U.S. allies and partners in the event of hostilities.
The 35th Supply and Service Battalion maintains APS Three and Four Stocks and Equipment in support of contingencies across the full spectrum of military operations. It provides logistics and Site support to Joint and Bilateral exercises throughout Japan, and provides installation management and support to 14 activities on the Sagami General Depot. The Battalion ensures quality of life for 1200 soldiers, civilians and their family members
On 1 May 1959 the General Depot organization was discontinued and the Sagami installation renamed the U. S. Army Japan Depot Complex. The principal effect of the reorganization as to place the executive direction of the supply and maintenance activities of the technical services with the chiefs of those services at Headquarters, U. S. Army Japan. It remained in this organizational posture until the organization of the U. S. Army Depot, Japan on 11 March 1963 under General Order No. 10, dated 7 March 1963, which discontinued the technical services logistics system at Sagami.
On 1 September 1969, the U. S. Army Depot Command, Japan was discontinued and the existing organizational elements of the Depot Command and the staff elements of Headquarters, U. S. Army Japan were merged into a single unified U. S. Army Japan organization operated under a directorate-type structure in which staff and operational functions were combined until the activation on 7 August 1971 of the U. S. Army Supply and Maintenance Activity (Provisional), Sagami (USASMAS). Concurrently, the U. S. Army Japan, Directorate for Supply and Storage (less the U. S. Army Ammunition Depot Complex, Akizuki), Directorate for Maintenance, and Directorate for Quality and Engineering were designated as organizational elements of USASMAS. The provisional organization became permanent on 15 February 1972. USASMAS was reduced on 1 July 1973 by the transfer of its Property Disposal (PDO) function to Defense Supply Agency (DSA) which utilized the personnel and facilities to establish Defense Property Disposal Region-Pacific. Then, on 1 April 1974, upon completion of its support mission for tactical wheeled vehicles, which were procured in Japan for Southeast Asian MAP - recipient countries, the Directorate of Quality and Engineering was deactivated.
On 1 July 1974, due to termination of the missions in support of Southeast Asia, the U.S. Army Supply and Maintenance Activity, Sagami was deactivated and the residual supply and maintenance functions were assigned to the Directorate of Industrial Operations, U. S. Army Garrison, Honshu which was activated on the same day as a subordinate command of U.S. Army Japan. U. S. Army Japan at the time was a subordinate command of U. S. Army Pacific.
With the discontinuance of U. S. Army Pacific on 31 December 1974, U. S. Army Japan was designated a major Army command on 1 January 1975, leaving USARJ with two subordinate commands, U. S. Army Garrison, Okinawa and U. S. Army Garrison, Honshu.
U. S. Army Garrison, Honshu, was re-designated the 9th Area Support Group (PROV) on 16 January 1986. The 35th Supply and Service Battalion (PROV), located at Sagami Depot, also, was established on this date. The 9th Area Support Group terminated its provisional status on 15 October 1987, and was activated as the 17th Area Support Group. The 35th Supply and Service Battalion (PROV) also dropped its provisional status on 15 October 1987 and was activated as the 35th Supply and Service Battalion.
