1947 Meisinger stated that he was not in Warsaw after October 1940, but it is likely that he participated in the creation of the Warsaw Ghetto. Activities in Shanghai and Japan From 1 April 1941 to May 1945 Meisinger acted as Gestapo liaison connecting leaders and particular agents of the SD at the German Embassy in Tokyo. His duties included seeking out enemies of the Third Reich within the German community, using various informants. He was also the SD liaison officer to the Japanese Secret Intelligence Service. One of his tasks in Japan was the observation of the secret Soviet agent Richard Sorge (who was under suspicion in Berlin) but Meisinger soon became Sorge's constant drinking companion and, unwittingly, one of Sorge's best sources of information. In 1941 Meisinger tried to influence the Japanese to exterminate approximately 18,000–20,000 Jews who had escaped from Austria and Germany and who were living in Japanese-occupied Shanghai. His proposals included the creation of a concentration camp on Chongming Island in the delta of the Yangtze, or starvation on freighters off the coast of China. The Japanese admiral responsible for overseeing Shanghai would not yield to pressure from Meisinger; however, the Japanese built a ghetto in the neighborhood of Hongkew which had already been planned by Tokyo in 1939: a slum with about twice the population density of Manhattan. The ghetto was strictly isolated by Japanese soldiers under the command of the Japanese official Kano Ghoya, and Jews could only leave it with special permission. Some 2,000 of them died in the Shanghai Ghetto during the wartime period. Arrest, trial and conviction On 6 September 1945 Meisinger surrendered to two war correspondents, Clark Lee of the INS and Robert Brumby of MBS, at the Fujiya Hotel in Hakone, Kanagawa. The reporters drove him to the Yokohama headquarters of the Counter-Intelligence Corps where Meisinger turned himself in. He was held in the Yokohama Jail where he underwent intensive questioning for two weeks before being transferred to U.S. General Dwight D. Eisenhower's headquarters in Frankfurt. In November 1945, under the escort of Lt. Col. Jennis R. Galloway, and Major James W. McColl, both of the 441st CIC detachment, he was flown to Washington, D.C. for questioning on his involvement in the destruction of the Warsaw Ghetto. In 1946 he was extradited to Poland. In Warsaw on 17 December 1946 he was charged, together with Ludwig Fischer (Nazi
