This map represents the Japanese / Japanese American population distribution in Manhattan, according to the 1930 US Census, and selected ethnic Japanese–owned businesses that were operating in Manhattan in 1930 (or, where noted, were established later in the decade). For ease of reference, the Census data has been placed on a 2017 street map. Each purple data point (circle) represents one or more persons of Japanese ethnicity. The green data points represent specific locations of key businesses and social institutions in the New York Japanese community as well as general locations of neighborhood districts in Manhattan and in parts of Brooklyn, Queens, and the Bronx.
