Even before Congress declared war on Japan the day after Pearl Harbor, the implications for people of Japanese ancestry living in the United States had begun. On December 7th, several hundred Issei, or first-generation Japanese immigrants, were arrested in Hawaii and on the mainland, having been earlier identified by the FBI as potentially disloyal to the United States. In the months that followed, the scope of suspicion would expand to include all of the 125,000 Japanese living on the mainland, and, though a smaller percentage, many in Hawaii as well. By the time the war ended, the period of internment of Japanese immigrants and citizens, lasting from 1941-1945, was considered one of the most unfortunate episodes of American history.
