Bond is introduced to Tanaka—and to the Japanese lifestyle—by an Australian intelligence officer, Dikko Henderson. When Bond raises the purpose of his mission with Tanaka, it transpires that the Japanese have already penetrated the British information source and Bond has nothing left to bargain with. Instead, Tanaka asks Bond to kill Dr. Guntram Shatterhand, who operates a politically embarrassing "Garden of Death" in a rebuilt ancient castle on the island of Kyushu; people flock there to commit suicide. After examining photos of Shatterhand and his wife, Bond discovers that "Shatterhand" and his wife are Tracy's murderers, Ernst Stavro Blofeld and Irma Bunt. Bond gladly takes the mission, keeping his knowledge of Blofeld's identity a secret so that he can exact revenge for his wife's death. Made up and trained by Tanaka, and aided by former Japanese film star Kissy Suzuki, Bond attempts to live and think as a mute Japanese coal miner in order to penetrate Shatterhand's castle. Tanaka renames Bond "Taro Todoroki" for the mission.
