I believe it was around 3500 BC.
Japanese American internment happened during World War II when the United States government forced about 110,000 Japanese Americans to leave their homes and live in internment camps. These were like prisons. ... On December 7, 1941, Japan attacked Pearl Harbor in Hawaii and declared war on the United States.
Japanese Americans died in the camps due to inadequate medical care and the emotional stresses they encountered. Several were killed by military guards posted for allegedly resisting orders.
nexpensive foods such as wieners, dried fish, pancakes, macaroni and pickled vegetables were served often. Vegetables, which had been an important part of the Japanese Americans' diet on the West Coast, were replaced in camp with starches.
