Tanforan Assembly Center

About

The Tanforan Assembly Center was created to temporarily detain nearly 8,000 Japanese Americans, mostly from the San Francisco Bay Area, under the auspices of Executive Order 9066. After the order was signed in February 1942, the Wartime Civil Control Administration acquired Tanforan Racetrack on April 4 for use as a temporary assembly center; plans called for the site to be used to accommodate up to 10,000 "evacuees" while permanent relocation sites were being prepared further inland. The Tanforan Assembly Center began operation in late April 1942, the first stop for thousands who were forced to relocate and undergo internment during World War II. The majority were U.S. citizens of Japanese ancestry who were born in the United States. Tanforan Assembly Center was operated for slightly less than six months; most detainees at Tanforan were transferred to the Topaz War Relocation Center in Utah, starting in September. The transfer to Topaz was completed by mid-October, and the site was turned over to the Army a few weeks later.
