The first Japanese to land in the United States arrived on May 7, 1843. Since this early arrival, Japanese Americans (日系アメリカ人 Nikkei Amerikajin)remain primarily on the West Coast, but pockets exist all across the country in smaller numbers. For a long time Japanese Americans were among the top three largest Asian communities, particularly during the 20th century; but, according to the 2000 census, they have dropped to the sixth largest group at around 1.4 million, including halvsies.
According to the 2010 census, the largest Japanese American communities were found in California at around 272,528, Hawaii with about 185,502, New York with around 37,780, Washington with 35,008, Illinois with 17,542, and Ohio with 16,995. Pockets are generally driven by North American HQ of Japanese companies.
Southern California has the largest, and longest standing, Japanese American populations in North America. The city of Torrance, just south of Los Angeles, holds the densest Japanese American population in the 48 mainland states.
Some famous American halvsies include: Cary Joji Fukunaga, director of the new James Bond film; Steve Aoki, DJ; Sean Lennon, Musician; and Hayley Kiyoko, actress and singer.
