The bombing of Pearl Harbor took place in Hawaii on December 7, 1941, during World War II. The Japanese bombed Pearl Harbor destroying much of the American Pacific Fleet. The American were very fearful of any Japanese descendent afterwards. At the time, 112,000 people of the Japanese descent lived on the West Coast; 70,000 of them were American citizens. The Americans restricted the Japanese descent from some places in the city, or they sent them to live in barracks. In the barracks, there was no running water or cooking facility. All they were allowed to bring was personal items.
Fred Korematsu was an American-born citizen of the Japanese descent. He grew up in Oakland, California. He tried to serve in the American military but was rejected for poor health. When the internment began in California, Korematsu moved to another town, got facial surgery, changed his name, and claimed to be Mexican-American.
