On the battlefield, the American propaganda led their soldiers to believe that Japanese soldiers died with the Emperor’s name on their lips. Actually most Japanese men called for their wives or mothers just like the Americans. But it was a powerful image that helped to explain the mass suicides that the Americans encountered prior to Iwo Jima. Except for occasional mention, Allied propaganda tried to avoid painting the Emperor as demagogue on the level of Hitler, because Allied command was worried that if the American public thought the Emperor should be removed, the Japanese would never surrender.
Hirohito was instrumental in ending the war. His intervention and subtle calls for surrender convinced the cabinet that it was time to cease hostilities. In a complex series of discussions with the cabinet members who favored continued resistance, the Emperor was able to communicate his desires without causing the government to plunge into chaos. A group of officers did attempt to breach the Imperial Palace grounds to assassinate the Emperor, in the Emperor’s name, and continue the war. They were stopped, and the coup failed.
Hirohito remained Emperor until his death in 1989. Several right-wing Japanese groups were agitated by his death, but the nation as a whole mourned the passing of the last World War II leader to die.
