Excerpts from Books and Wikipedia
"The Allied occupation had begun in September 1945, after the Japanese surrender, and the trials started in May 1946. . . . By the occupation's end in 1952, Japan had a democratic constitution, the Emperor had renounced his divinity, and militarism was a thing of the past." [Furtado: 1001 Days] "The Tokyo trial, despite its defective procedures and complex political nature, had a deep, many-sided impact on the Japanese people and their view of the lost war. . . . The Tokyo tribunal succeeded in revealing both the deceit of the war leaders and their unwillingness to admit criminal liability for their actions while in office. It disclosed, for the first time in Japan, the facts about the assassination of Chang Tso-lin and the Kwantung Army conspiracy that led to the Manchurian Incident. It documented the mistreatment and murder of Allied prisoners of war and civilians at scores of places in Asia and the Pacific, including most famously Bataan and the Thai-Burma railway over the river Kwai. Evidence of mass atrocities at Nanking was admitted . . . Many people resolved that Japan should never go to war again, and dedicated themselves to making democratic ideals and international norms work." [Hirohito, p. 612-8]
