Tokyo Rose

Tokyo Rose was a name given to about a dozen English-speaking female broadcasters for Japanese propaganda. Although, the name was most aimed toward Iva Toguri. A native to Los Angeles, stranded in Japan when war broke out, Iva's intent of the broadcasting was to mess with allied forces listening to the broadcast. American service men in the Pacific often listened to the propaganda broadcasts to get a sense, by reading between the lines, the effect of their military actions. Toguri often underminded the anti-American scripts by reading them in a playful, tongue-in-cheek fashion, even going as far as warning her listeners to be aware for "subtle attacks'' in a demeaning manner.
Farther from the action, stories circulated by Tokyo Rose could be unnervingly accurate, even able to name units and servicemen. Toguri's prominence saw her branded as one of the war's most notorious propagandists, but evidence shows that she was not a Japanese sympathizer. Toguri's program became conflated with vicious propaganda, resulting in her arrest after Japanese surrender. Convicted with treason, Toguri was sent to jail, then arrested and released from prison in 1956. For WWII, the name Tokyo Rose was used against female propagandists, but mainly against Iva Toguri.
