During World War Two, over one-hundred thousand Japanese-American individuals, the vast majority of which were actually American citizens, were rounded up and shipped eventually to internment camps.  These consisted of poorly constructed barracks surrounded by barbed wire, sentry posts, and armed guards.  The were put in these camps because they were found guilty, but because they or their parents were from Japan and as such, they were a "threat" to national security.  They were also easily identifiable due to their race.  These people were forced to abandon their businesses, homes, and in many cases their families as some individuals were taken elsewhere, again for years, without trial.  The Japanese suffered sever economic losses, personal humiliation and in somes cases, death, due to this relocation ("Japanese-American Internment Camps"). 

    The Japanese-American (Nisei) and the Japanese aliens (Issei) on the West Coast were rounded up and moved to assembly centers and then to internment camps. Few Japanese living in the East or Midwestern portions of the U.S., though, were treated the same way.  What is extremely interesting is that the Nisei and Issei living in Hawaii were not subject to a mass evacuation even though they formed a third of the population in Hawaii and were a lot closer to Japan than the Japanese-Americans on the West Coast of the U.S.  The reasons they weren't rounded up were both cultural and economic ("Japanese-American Internment Camps").

    "There was no mass relocation internment in Hawaii, where population was one-third Japanese.  It would have been impossible to transport that many people to the mainland, and the Hawaii economy would have collapsed without Japanese" (Sakurai).
