Foreign Minister Tōgō’s Bitter Struggle and the Acceptance of the Potsdam Declaration

Japan’s decision to accept the terms of the Potsdam Declaration was one of the most pivotal events in the country’s modern history. Most students of the decision-making process agree that Foreign Minister Tōgō Shigenori was the principal motive force supporting acceptance of the Allies’ demands throughout the debate over the action. Some recent historiography in Japan has questioned Tōgō’s approach, focusing particularly on his decision to seek the mediation of the Soviet Union and on the question of why he did not bring hostilities to an end sooner. Historical materials that were previously unavailable to scholars shed some light on these questions. In combination with Tōgō’s daily planner (in the author’s possession), his memoirs, and the author’s own recollection of anecdotes his parents told to him, these materials make possible a detailed examination of Tōgō’s thoughts and actions in the days leading to the acceptance of the Potsdam Declaration. This shows that Tōgō, facing stubborn resistance from the military and from public opinion, nevertheless persevered in his quest to bring the war to an end. He also maintained the trust and respect of not only Emperor Hirohito, but also of Army Minister Anami Korechika, his principal antagonist in the debate.
