Hideki Tōjō was a general of the Imperial Japanese Army (IJA), the leader of the Taisei Yokusankai, and the 40th Prime Minister of Japan during most of World War II.
As Prime Minister, he was directly responsible for the attack on Pearl Harbor, which initiated war between Japan and the United States, although planning for it had begun before he entered office.
Tōjō was arrested and underwent emergency surgery in a U.S. Army hospital. After recovering from his injuries, Tōjō was moved to Sugamo Prison.
While there he received a new set of dentures made by an American dentist. Secretly the phrase "Remember Pearl Harbor" had been drilled into the teeth in Morse code.
The Prime Minister was sentenced to death for Japanese war crimes by the International Military Tribunal for the Far East, and was hanged on December 23, 1948.
