Fugu plan "is a plan put forward by Japan after its occupation of Northeast China, hoping to adopt a policy of fostering and being friendly to Jews, so as to consolidate their rule in" Manchukuo "and influence Britain and the United States' attitude towards Japan. 1934 The term "fugu plan" officially appeared. Tankawa Yoshisuke, a great entrepreneur in the steel industry, published an article entitled "A Plan to Invite 50,000 German Jews to Manchukuo" in a diplomatic journal. Later, there was the so-called "fugu plan". This plan believes that Jews will be very beneficial to Japan, but it is also very dangerous. Therefore, this plan was specially named "puffer fish", because puffer fish will kill people if it is not cooked correctly and carefully. The Japanese compare Jews to puffer fish, thinking that they should eat their delicious food after removing their "toxins". 19381February 5, the Japanese cabinet "five-phase meeting" reached an agreement on "fugu plan". Since then, the content of "fugu plan" has been more detailed and improved, and the proposal of establishing a Jewish settlement in Shanghai or "Manchukuo" in China has been put forward. The supplemented text of fugu plan is 90 pages long, with complicated contents. Its main points are as follows: to establish a "Jewish settlement" in China under Japanese occupation, first resettle 30,000 Jewish refugees, and then gradually expand it; The cost of establishing this residence is borne by the American Jewish consortium, and the resettlement fee of 1 100 million dollars is needed first; Vigorously promote this plan in the United States and other western countries, and invite Jewish celebrities from all over the world to visit the residence; Attracting Jewish capital by establishing settlements and improving relations with the United States and other western countries. Experts are still controversial about whether to establish a "Jewish settlement" in Manchukuo or Shanghai, and there is no conclusion. In fact, the other contents of "fugu plan" are mostly on paper and have not been implemented in practice. 1940 in July, Japan concluded a military alliance with Germany and Italy (the three-nation convention was only publicly signed in September), and the "fugu plan" stopped.

1942, the Japanese government officially abolished the resolution of the five-phase meeting and officially abolished the almost nonexistent support for this almost nonexistent puffer fish plan.
