Japanese consul to Kaunas, Lithuania, Chiune Sugihara issued thousands of visas to Jewish refugees who were escaping the Nazi's Final Solution to the Jewish Question. They traveled from Keidan, Lithuania across Russia by railroad to the Vladivostok from where they traveled by ship to Kobe, Japan. Their stay in Kobe was short as the Japanese government transferred them to Shanghai by November 1941. Other Jewish refugees found haven in Shanghai, not through Sugihara, but came on ships from Italy. The refugees from Europe were interned into a cramped ghetto in the Hongkou District, and after the Japanese attack on Pearl Harbor, even the Iraqi Jews who had been living in Shanghai from before the outbreak of WWII were interned. Among the refugees in the Shanghai Ghetto was the Mirrer Yeshiva, including its students and faculty.

As the industrial center of China with the most skilled industrial workers, Shanghai became a center for radical leftism during the 1950s and 1960s. The radical leftist Jiang Qing and her three allies, together the Gang of Four, were based in the city.
