In 1946, Puyi testified at the International Military Tribunal for the Far East in Tokyo, detailing his resentment at how he had been treated by the Japanese. At the Tokyo trial, he had a long exchange with defense counsel Major Ben Bruce Blakeney about whether he had been kidnapped in 1931, in which Puyi perjured himself by saying that the statements in Johnston's 1934 book "Twilight in the Forbidden City" about how he had willingly become Emperor of Manchukuo were all lies. When Blakeney mentioned that the introduction to the book described how Puyi had told Johnston that he had willingly gone to Manchuria in 1931, Puyi denied being in contact with Johnston in 1931, and that Johnston made things up for "commercial advantage". The Australian judge Sir William Webb, the President of the Tribunal, was often frustrated with Puyi's testimony, and chided him numerous times. Behr described Puyi on the stand as a "consistent, self-assured liar, prepared to go to any lengths to save his skin", and as a combative witness more than able to hold his own against the defense lawyers. Since no one at the trial but Blakeney had actually read "Twilight in the Forbidden City" or the interviews Woodhead had conducted with him in 1932, Puyi had room to distort what had been written about him or said by him. Puyi greatly respected Johnston, who was a surrogate father to him, and felt guilty about portraying him as a dishonest man.
