The Tanaka Memorial (, Tanaka Jsbun) is an alleged Japanese strategic planning document from 1927 in which Prime Minister Baron Tanaka Giichi laid out for Emperor Hirohito a strategy to take over the world. The authenticity of the document was long accepted and it is still quoted in some Chinese textbooks, but historian John Dower states that "most scholars now agree that it was a masterful anti-Japanese hoax."



The prime minister of Japan (日本国内閣総理大臣, Nihon-koku naikaku sōridaijin, or shushō (首相)) (informally referred to as the PMOJ) is the head of the executive branch of the government of Japan. The prime minister directs the National Cabinet and is the commander-in-chief of the Japan Self-Defense Forces; he is appointed by the emperor of Japan after being designated by the National Diet and must enjoy the confidence of the House of Representatives to remain in office. He is the head of the Cabinet and appoints and dismisses the other ministers of state. The literal translation of the Japanese name for the office is Minister for the Comprehensive Administration of (or the Presidency over) the Cabinet.

The current prime minister of Japan is Fumio Kishida, who replaced Yoshihide Suga on 4 October 2021.
