When did Hirohito die?
Hirohito died on January 7, 1989 at the age of 87.
Emperor Hirohito was never placed on trial during the Tokyo Trials after World War II. In fact, General MacArthur went to great lengths to prevent Hirohito from being implicated in any war crimes. General Tojo Hideki mentioned Hirohito during his testimony and a brief recess was called so that he would have the opportunity to recant. General MacArthur knew that Hirohito remaining as Emperor was pivotal for the success of Japan post-WWII.
