Despite there being little evidence to suggest that the Japanese had ever contemplated a Jewish state or a Jewish autonomous region, Rabbi Marvin Tokayer and Mary Swartz published a book called 'The Fugu Plan' in 1979. In this partly fictionalized book, Tokayer and Swartz gave the name the Fugu Plan or Fugu Plot(河豚計画Fugu keikaku) to memorandums written in the 1930s Imperial Japan proposing settling Jewish refugees escaping Nazi-occupied Europe in Japanese territories. Tokayer and Swartz claim that the plan, which was viewed by its proponents as risky but potentially rewarding for Japan, was named after the Japanese word for puffer-fish, a delicacy which can be fatally poisonous if incorrectly prepared.
