The Tanaka Memorial: A Secret Blueprint for World Conquest – S6-E11

In the 1930s, a mysterious document known as the Tanaka Memorial shocked the world. Supposedly written by Japanese Prime Minister Baron Tanaka, it outlined a strategy for conquering Manchuria, China, Southeast Asia, and even the United States. As real-life events seemed to unfold according to the alleged plan, the document became one of the most influential pieces of anti-Japanese propaganda of the twentieth century. It was quoted by American films, politicians, and many others. In this episode, we tell the story of Taiwanese businessman Tsai Chih-kan (蔡智堪), who later claimed to have personally copied the secret plans from inside the Japanese Imperial Palace. Although most historians today believe the Tanaka Memorial was a forgery, it remains an unsolved mystery. And the story of how it shaped global politics and wartime propaganda is, we think, more fascinating than the contents of the document.
