Sagami General Depot is located in the city of Sagamihara, Kanagawa Prefecture, Honshu, Japan.

Sagami Depot was also the test bed for the development of the 120-ton “O-I” experimental heavy tank as well as manufacturing balloon incendiary devices which Japanese forces launched from Chiba to start fires in the west coast region of the U.S.

In 1957 the Army began to scale back operations at Sagami General Depot and U.S. Army Supply and Maintenance Activity (which performed maintenance and repair of heavy equipment and tanks) was inactivated after the Vietnam War.

In September 2015, land for the former housing area was returned to Japan with a portion designated for joint use.
