Befriended by
Imperial Japanese Army Colonel Yasue and General Kiichirō Higuchi, the engineers of the later-named "
Fugu Plan", Kaufman organized three large conferences of the Far Eastern Jewish Council, which brought together Jews from across East Asia, and successfully appealed for his organization to be accepted under the umbrella of the
World Jewish Congress. Through these conferences, he worked to encourage Jews from other parts of the region, and the world, to think of
Manchukuo as a safe-haven for Jews, reassuring them, as his Japanese friends had assured him, that the Japanese were not
anti-Semitic, nor inclined to be racially discriminatory against Jews. He formally thanked
Prime Minister Nobuyuki Abe for the prejudice-free protection offered Jews in East Asia by the Japanese authorities, and suggested that the global Jewish community would be grateful should Japan create a safe haven in East Asia, and that in return the Jewish communities of East Asia would support Imperial
Japan's vision for a new order in East Asia. By 1942, a great number of Jews had sought refuge in Japan from Eastern Europe, settling in
Kobe before being moved to the
Shanghai Ghetto in China. As early as 1941, the local
Gestapo chief
Josef Meisinger (
The Butcher of Warsaw) visited the ghetto, and proposed plans to
exterminate its Jewish population. Kaufman, through his influence and contacts in the Japanese government, prevailed upon Tokyo to prevent Meisinger's plans being carried out. Ultimately, Kaufman succeeded and Meisinger's schemes were rejected by Tokyo, but not before the doctor along with seven other Jewish community leaders were arrested, imprisoned, and maltreated by the
Kempeitai (Japanese military police) as traitors for accusing Japan of plotting
genocide. All but one of the community leaders were released days or weeks after their arrests. Following his release, Kaufman returned to Harbin, and to his activities with the Far Eastern Jewish Council, which included raising substantial donations to the severely impoverished Jewish community in Shanghai. == Post–war arrest by the Soviets ==
