The microphone used by Iva Toguri D’Aquino, known as “Tokyo Rose”, on display in the National Museum of American History.

The name "Tokyo Rose" is strongly associated with Iva Toguri D’Aquino, an
American citizen born to Japanese immigrants. D’Aquino broadcast as "Orphan
Ann" during the 15-20 minute D.J. segment of the 75-minute program The Zero
Hour on Radio Tokyo (NHK). The program consisted of propaganda-tinged skits
and slanted news reports as well as popular American music .Rose routinely
identified American units on air, sometimes even naming individual soldiers. Her purported predictions of impending attacks were, according to many, extremely
accurate.
