Jewish settlement in the Japanese Empire
Shortly prior to and during World War II, and coinciding with the Second Sino-Japanese War, tens of thousands of Jewish refugees were resettled in the Japanese Empire. The onset of the European war by Nazi Germany involved the lethal mass persecutions and genocide of Jews, later known as the Holocaust, resulting in thousands of Jewish refugees fleeing east. Many ended up in Japanese-occupied China.
The memorandums
Memorandums written in 1930s Imperial Japan proposed settling Jewish refugees escaping Nazi-occupied Europe in Japanese-controlled territory. As interpreted by Tokayer and Swartz (who coined the term "Fugu Plan" to describe this), they proposed that large numbers of Jewish refugees should be encouraged to settle in Manchukuo or Japan-occupied Shanghai, thus gaining the benefit of the supposed economic prowess of the Jews and also convincing the United States, and specifically American Jewry, to grant political favor and economic investment into Japan. The idea was partly based on the acceptance of the The Protocols of the Elders of Zion as being as a genuine document by at least part of the Japanese leadership.
