History of the Japanese in San Francisco

There is a Japanese American and a Japanese national population in San Francisco and the San Francisco Bay Area.
History.
The history of the Japanese in San Francisco begins in 1869 when the first Japanese immigrants arrived in San Francisco Bay. Initially, Japanese immigrants moved to the edge of San Francisco's Chinatown and the South of Market neighborhood. 
Asian American Studies professor Yuji Ichioka estimated that there around 300 Japanese "school boys"—immigrants who are working to earn their education in the United States—living in San Francisco in 1885. 
Following the San Francisco Earthquake in 1906, the Japanese community relocated to the city's present day Japantown in the Western Addition, and also the South Park neighborhood. In 1900 there were 90 Japanese businesses. By 1909 this figure increased to 545. 
Following the 1906 earthquake, the San Francisco Board of Education passed a regulation requiring that Japanese American students attend separate, racially specific schools. This local action led to an international dispute, following the vigorous objections of the Japanese government. The result of the dispute was the Gentlemen's Agreement of 1907, which greatly restricted the flow of Japanese nationals to the United States.
San Jose's Japantown was founded due to the need of combining comradeship and resources to survive as immigrants in the United States. Initially, it was known as Heinlenville Chinatown between Jackson and Taylor east of Sixth Street. However, John Heinlen offered his own property for the new location after the city's second Chinatown burned to the ground under mysterious circumstances. Despite outrage from the general public, Mr Heinlen built a new Chinatown entirely of brick. He then rented these buildings to the Chinese at very low rates.
During World War II, San Francisco saw the largest and oldest enclave of Japanese outside of Japan, Japantown, completely empty out its ethnic Japanese residents as a result of Executive Order 9066 that forced all Japanese of birth or descent in the United States to be interned. By 1943 many large sections of the neighborhood remained vacant due to the forced internment.
Following the war, some Japanese Americans returned, followed by new Japanese immigrants as well as investment from the Japanese Government and Japanese companies. However, many did not return to the neighborhood and instead settled in other parts of the city, or out to the suburbs altogether. This was further exacerbated by the city's efforts to rejuvenate the neighborhood initiated by Justin Herman in the Western Addition in the 1960s through the 1980s.
Civil rights attorney Wayne M. Collins, who worked many prominent cases on behalf of members of the Japanese American community, both lived and worked in San Francisco until his death in 1974. Among his clients were Fred Korematsu, Iva Toguri D'Aquino, and Japanese American renunciants from the Tule Lake War Relocation Center.
Institutions.
The "Fukuin Kai" opened in 1877. The book "San Francisco's Japantown" stated that this was believed to be the first Japanese organization in the United States.
Education.
The San Francisco Japanese School (SFJS) is a Japanese Ministry of Education (MEXT)-designated weekend Japanese school serving the area. The school system, headquartered in San Francisco, rents classrooms in four schools serving a total of over 1,600 students as of 2016; two of the schools are in San Francisco and two are in the South Bay.
