Camp Zama is close to the Sagami River near the foothills of the Tanzawa Mountain Range, Kanagawa Prefecture. The installation falls in the Zama City limits while the two housing areas, Camp Zama and Sagamihara Family Housing Area (SFHA), are located in the adjacent Sagamihara City. Once considered rural, this area has transformed into an urban area. New housing developments and communities along with shopping centers have increased the population and made traffic extremely congested.
