In 1945, on this day the unconditional surrender of Japan was prevented by the actions of the officers of the 2nd Brigade Imperial Guard and the Staff Office of the Ministry of War who occupied the Tokyo Imperial Palace and placed the Emperor under house arrest.
The Kyūjū IncidentA meeting of the Supreme Council for the Direction of War had agreed to accept the Potsdam Declaration. The act of unconditionally surrender was imminent; all that was required was the instrument: the writing of an official communiqué to be sent by the Japanese envoy of Switzerland and Sweden.
But after the proceedings, some Army officers for protection of the sovereign decided that a coup d'état was needed instead. They managed to persuade the Eastern District Army and the high command of the Imperial Japanese Army to move forward with the action and in the event, the communiqué was written but never sent.
With the Emperor in protective custody, a rather different set of words were drafted which would form the basis of an alternate speech declaring Japan's intention to fight down to the last man, woman and child. That is, unless a counter-coup could be pulled off to prevent the broadcast from ever happening..
