Japanese-American internment was the forced relocation and internment by the United States government in 1942 of approximately 110,000 Japanese Americans and Japanese residing along the Pacific coast of the United States to camps called “War Relocation Camps,” in the wake of Imperial Japan’s attack on Pearl Harbor. The internment of Japanese Americans was applied unequally throughout the United States. Japanese Americans residing on the West Coast of the United States were all interned, whereas in Hawaii, where more than 150,000 Japanese Americans composed nearly a third of that territory’s population, 1,200 to 1,800 Japanese Americans were interned. Of those interned, 62% were American citizens.
