During the Second World War, Japanese propagandist and DJ Tokyo Rose broadcasted to American and Allied soldiers from somewhere behind enemy lines. Her broadcasts were intended to disrupt morale, although it is questionable how much of a real effect thay had. Still, it was rumoured that she named individual GIs, and that she accurately predicted attacks.
In fact, “Tokyo Rose” seems to have been was not one woman but a group of women, possibly as many as a dozen. The identity or identities of Tokyo Rose hasve never been conclusively established, but the best known suspect is Iva Toguri D’Aquino, who was charged with various crimes related to Tokyo Rose on September 5, 1945 (two days after the official Japanese surrender).
She was tried for treason and other crimes, convicted despite somewhat dubious evidence against her, and sentenced to ten years imprisonment, plus a fine of US $10,000. She was later paroled after serving a little over six years of her sentence. In 1976, an FBI investigation found that several witnesses had lied on the stand to damage her chances. On his last day in office, President Gerald Ford granted Toguri a full and unconditional pardon, and restored her US citizenship.
