In early 1945, in the wake of the losses in the Battle of Leyte, Emperor Hirohito began a series of individual meetings with senior government officials to consider the progress of the war. All but ex-Prime Minister Fumimaro Konoe advised continuing the war. Konoe feared a communist revolution even more than defeat in war and urged a negotiated surrender. In February 1945 during the first private audience with the Emperor he had been allowed in three years, Konoe advised Hirohito to begin negotiations to end the war. According to Grand Chamberlain Hisanori Fujita, the Emperor, still looking for a tennozan (a great victory) in order to provide a stronger bargaining position, firmly rejected Konoe's recommendation.
On 22 June the Emperor met with his ministers saying, "I desire that concrete plans to end the war, unhampered by existing policy, be speedily studied and that efforts be made to implement them." The attempt to negotiate a peace via the Soviet Union came to nothing. There was always the threat that extremists would carry out a coup or foment other violence. On 26 July 1945, the Allies issued the Potsdam Declaration demanding unconditional surrender. The Japanese government council, the Big Six, considered that option and recommended to the Emperor that it be accepted only if one to four conditions were agreed upon, including a guarantee of the Emperor's continued position in Japanese society. The Emperor decided not to surrender.
On 12 August 1945, the Emperor informed the imperial family of his decision to surrender. One of his uncles, Prince Yasuhiko Asaka, asked whether the war would be continued if the kokutai (national polity) could not be preserved. The Emperor simply replied "Of course." On 14 August the Suzuki government notified the Allies that it had accepted the Potsdam Declaration.
Hirohito was not put on trial, but he was forced to explicitly reject the quasi-official claim that the Emperor of Japan was an arahitogami, i.e., an incarnate divinity. This was motivated by the fact that, according to the Japanese constitution of 1889, the Emperor had a divine power over his country which was derived from the Shinto belief that the Japanese Imperial Family were the descendants of the sun goddess Amaterasu. Hirohito was however persistent in the idea that the Emperor of Japan should be considered a descendant of the gods. In December 1945, he told his vice-grand-chamberlain Michio Kinoshita: "It is permissible to say that the idea that the Japanese are descendants of the gods is a false conception; but it is absolutely impermissible to call chimerical the idea that the Emperor is a descendant of the gods." In any case, the "renunciation of divinity" was noted more by foreigners than by Japanese, and seems to have been intended for the consumption of the former. The theory of a constitutional monarchy had already had some proponents in Japan. In 1935, when Tatsukichi Minobe advocated the theory that sovereignty resides in the state, of which the Emperor is just an organ (the tennō kikan setsu), it caused a furor. He was forced to resign from the House of Peers and his post at the Tokyo Imperial University, his books were banned, and an attempt was made on his life. Not until 1946 was the tremendous step made to alter the Emperor's title from "imperial sovereign" to "constitutional monarch."
