It is the summer of 1940. Japan’s war in China has just entered its fourth year, with no end in sight. While officially neutral, the United States and Great Britain have been assisting the Chinese, and are threatening economic sanctions against Tokyo. With few natural resources of its own, Japan’s industrial economy depends on imported raw materials—particularly oil. However, Germany’s recent conquests in Europe may have just presented Japan with a golden opportunity, as French, Dutch, and British possessions in Asia lay largely undefended. Taking on the roles of leading figures in Tokyo—army or navy officers, bureaucrats, business executives, politicians, and members of the Imperial Court—participants are thrust into the middle of Japan’s strategic dilemma. Influenced by the tradition of bushido, and armed with the works of Japanese thinkers of the late 19th and early 20th centuries, they must advise the emperor on how to proceed. Will they call for a “strike south” to seize the natural resources of Southeast Asia—even at the risk of war with Britain and America? Or will they seek an understanding with England and America—even if it means giving up Japan’s conquests in China? Similarly momentous decisions must also be made on domestic policy. How will Japan’s increasingly scarce resources be allocated? Will the powerful privately-owned zaibatsu continue to dominate the economy, or will they be forced to subordinate their interests to the demands of the state?
