Executive Order 9066 was implemented in February 1942, which stated that "any and all persons may be excluded" from "military zones," which were stated to be the western region of Pacific Coast states and in Arizona. A crackdown followed the issue of the order almost immediately; Japanese businessmen and workers were arrested, Japanese-owned businesses were liquidated, and Japanese-owned financial assets were frozen. Internment processes followed suit one month later when Sacramento was placed into a military zone as dictated by Order 9066.
