List of U.S. cities with large Japanese-American populations

The list includes Issei (一世, "first generation") Japanese-born immigrants from Japan, and those who are multigenerational Japanese Americans. Cities considered to have significant Japanese American populations are large U.S. cities or municipalities with a critical mass of at least 1.0% of the total urban population; medium-sized cities with a critical mass of at least 2.0% of the total population; smaller communities in the continental United States with a critical mass of at least 2.5% of the total population; and smaller communities in Hawaii with a critical mass of at least 10.0% of the total population.
Including partial ancestry (i.e. Japanese and at least one other ethnic/racial group), there are about 1,469,637 Japanese Americans, which includes 773,714 Japanese Americans with pure Japanese ancestry, as of 2018. About 60% of the 773,714 pure Japanese American population lives in two states, California (36%; 272,528) and Hawaii (24%; 185,502).
