Up until 1906, San Francisco had been the main U.S. port of entry for Asian immigration and had the largest ethnic Japanese concentration of any city in the United States. Prior to the
1906 San Francisco earthquake, San Francisco had two Japantowns, one on the outskirts of
Chinatown, the other in the
South of Market area. After 1906, Japanese immigrants began moving to San Francisco's Western Addition, which then became San Francisco's main Japantown, with a smaller one in the
South Park area. By 1940, the Western Addition Japantown area (referred to as Nihonjin-machi) The ethnic Japanese population numbered over 5,000, and there were more than 200 Japanese-owned businesses. in 1942, during World War II.|alt= In February 1942, U.S. President
Franklin D. Roosevelt signed
Executive Order 9066, which forced all Japanese of birth or descent, including
Japanese-American citizens of the United States, to be relocated from the Pacific coast and
interned. By 1943 many large sections of the neighborhood remained vacant due to the forced internment. The void was quickly filled by thousands of
African Americans who had left the South to find wartime industrial jobs in California as part of the
Great Migration. 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 former residents did not return to the neighborhood after World War II and instead settled in other parts of the city, or out to the suburbs altogether. Depopulation of Japantown by ethnic Japanese was further instigated by the city's redevelopment plans initiated by
M. Justin Herman in the Western Addition in the 1960s through the 1980s. With little community input, existing housing was razed and transportation corridors were widened. In 1957, San Francisco entered into a
sister city relationship with the city of Osaka, hence the nickname "Little Osaka".
Osaka was San Francisco's oldest sister city. In commemoration of their 50th anniversary, one block of Buchanan Street in Japantown was renamed Osaka Way on September 8, 2007. However, Osaka ended the 60-year relationship in 2018 after then mayor
Ed Lee accepted
a statue memorializing
comfort women in 2017. The statue is currently erected on public property in
San Francisco's Chinatown. Japantown Bowl was founded in 1976 amidst
urban renewal in the
Fillmore District, San Francisco in the 1970s. When the building was put up for sale, Supervisor
Mabel Teng suggested that the city buy the building if negotiations between private investors failed. The Japanese Cultural and Community Center of Northern California (JCCCNC) offered to buy the building but was rejected. It was the largest of the three remaining bowling alleys in San Francisco when it closed in September 2000. The lot has since been converted into mixed-use housing units. A pair of
cherry blossom trees were planted by the JCCCNC outside of the center in 1994 to commemorate a visit by Emperor Emeritus
Akihito and Empress Emerita
Michiko of Japan during their 2-week tour of the United States. However, the trees were hacked down over the course of three days by vandals in January 2021. In 2020 due to the
COVID-19 pandemic in the United States, malls in San Francisco were ordered to remain temporarily closed whenever cases got high within the whole city followed by
Los Angeles and
San Diego. This, in effect, has forced restaurants in the neighborhood, many of whom reside in
Japan Center, to turn to a take-out/delivery-only model. The JCCCNC have organized
socially distanced outdoor seating and ordering areas in the Peace Plaza. However, some businesses have still remained closed for the duration of the pandemic and have reported losses of 50%. at
Japan Center. ==Attractions and characteristics==
