Japanese industrialist Raizo Yamata has been plotting to bring back his country to a position of greatness for years, partly as revenge for the death of his family at the hands of American forces invading the island of Saipan during World War II. His opportunity comes when a car accident in eastern Tennessee, caused by faulty gas tanks made in Japan, results in the deaths of six American people. The incident leads to the swift passage of a law allowing the U.S. to mirror trade practices of the countries from which it imports goods, cutting off the American export markets upon which the Japanese economy depends. Facing an economic crisis, Japan’s ruling zaibatsu, led by Yamata, decides to take economic and military action against the United States. Along with covert support from China and India, they plot to curtail the U.S. presence in the Pacific and re-establish the Greater East Asia Co-Prosperity Sphere. After the Japanese Prime Minister Mogataru Koga resigns in disgrace due to the economic situation, the zaibatsu installs Hiroshi Goto, an aggressive nationalist and critic of the U.S., to succeed him. Meanwhile, Japan has covertly developed nuclear weapons, and with SS-18 designs bought from the former Soviet Union, has fabricated and deployed several ICBMs.
