One of the strategies employed by the federal government to sell the forced removal and confinement of Japanese American from the West Coast during World War II was the use of euphemistic terms that masked the true nature of what was being done. Japanese American were "evacuated" — as if from a natural disaster or for their own protection — from their homes and sent to "assembly centers" and "relocation centers," names that gloss over the fact that these were concentration, prison, or detention camps.
Densho's policy is to avoid using these and other overtly euphemistic terms for the most part, except when quoting from historic documents or in proper nouns. Contributors to this encyclopedia were asked to adhere to these policies and also to limit the use of the term "internment" to the legally permissible detention of enemy aliens and not to refer to the mass forced removal and incarceration of Japanese Americans, most of whom were U.S. citizens.
