The Tanforan Assembly Center was located on the site of the Tanforan Racetrack in San Bruno, California. It was the second largest of the temporary WCCA camps, located 20 miles south of San Francisco, near the San Francisco International Airport. The camp was occupied from April 28 to October 13, 1942, a total of 171 days. Holding Japanese Americans mostly from the San Francisco Bay Area, its peak population was 7,816. All in all, 8,033 Americans of Japanese ancestry were incarcerated at Tanforan, 64 per cent of whom were U.S. citizens. About half of the inmates lived in former horse stalls. 98 per cent of the 7,824 Japanese Americans in Tanforan who were transferred to "relocation centers" were sent to the Central Utah WRA camp also known as Topaz. The site was subsequently used as a training camp by the VII Army Corps. A shopping center sits on the site today, a small historical marker commemorating its World War II history. [1]
