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.

Tanforan Racetrack, also known as Tanforan Park, was a thoroughbred horse racing facility in San Bruno, on the San Francisco Peninsula, in California. It was in operation from November 4, 1899, to 1964. The horse racing track and buildings were constructed to serve a clientele from nearby San Francisco. Between April and October 1942, the racetrack was the site of the Tanforan Assembly Center, an internment camp in which 8,000 Bay Area Japanese Americans were detained and processed for forced relocation and internment.The racetrack was destroyed by fire on July 31, 1964. The site is now the location of The Shops at Tanforan shopping center. The mall has a Tanforan Racetrack historical plaque, the Tanforan Assembly Center commemorative garden, and a statue of Seabiscuit.

San Bruno (Spanish for "St. Bruno") is a city in San Mateo County, California, United States, incorporated in 1914. The population was 43,908 at the 2020 United States Census. The city is between South San Francisco and Millbrae, adjacent to San Francisco International Airport and Golden Gate National Cemetery, and is approximately 12 miles (19 km) south of downtown San Francisco.

Golden Gate National Cemetery is a United States national cemetery in California, located in the city of San Bruno, 12 miles (20 km) south of San Francisco. Because of the name and location, it is frequently confused with San Francisco National Cemetery, which dates to the 19th century and is in the Presidio of San Francisco, in view of the Golden Gate. Around 1937, San Francisco residents voted to bar the opening of new cemeteries within the city proper and, as a result, the site for the new national cemetery was selected south of the city limits in adjacent San Mateo County.

The Shops at Tanforan is a regional shopping mall in San Bruno, California, United States. It is located on the San Francisco Peninsula, 10 miles (16 km) south of San Francisco city limits. It is served by the adjacent San Bruno Bay Area Rapid Transit (BART) station, as well as several local SamTrans bus lines and the Brisbane Shuttle. The complex is located minutes away from San Francisco International Airport. The site was originally used as a horse racing track from 1899 until 1964, when the grandstand was destroyed by fire; during World War II, the track was used as the Tanforan Assembly Center, where Japanese American citizens primarily from the San Francisco Bay Area were interned until more permanent War Relocation Centers were opened. Most Tanforan internees were sent to Topaz, Utah. A shopping mall was built on the site and opened in 1971. The mall underwent a 3-year renovation, and reopened in 2005. It continues to be anchored by one of its original 1971 retailers, JCPenney, while the other major anchor, Target, purchased its space from The Emporium in 1996. A Century Theatres was opened in 2008. In 2022, Alexandria Real Estate completed its acquisition of the site and announced the mall would be demolished and replaced with a biotech campus.

San Bruno Creek (Spanish for: "St. Brun") is an intermittent stream that rises on the eastern slopes of the Northern Santa Cruz Mountains in San Mateo County, California, USA. The headwaters descend a relatively steep canyon east of Skyline Boulevard in a tortuous course. Comparison of topographic maps from 1896 and 1939 illustrates the extreme modification in the lower reaches due to urban development from the rapidly expanding population. The San Bruno Creek watershed was originally settled by a tribe of the Ohlone, and later this locale was part of the Spanish missions' landholdings. A hiking trail winds along San Bruno Creek representing an important link in the San Francisco Bay Trail; in fact, this link is needed to make up for lack of access along a large bay front area occupied exclusively by San Francisco International Airport; thus, the Bay Trail must detour a full two miles inland from the bay to meet the San Bruno Creek Trail.

Artichoke Joe's Casino is a card club in San Bruno, California. The club is owned by Dennis Sammut and managed, in part, by Ron Cox, a former Foster City councilman.
