Eisaku Satō
Mishima hated Ryokichi Minobe, who was a communist and the governor of Tokyo beginning in 1967. Influential persons in the conservative Liberal Democratic Party (LDP), including Takeo Fukuda and Kiichi Aichi, had been Mishima's superiors during his time at the Ministry of the Treasury, and Prime Minister Eisaku Satō came to know Mishima because his wife, Hiroko, was a fan of Mishima's work. Based on these connections LDP officials solicited Mishima to run for the LDP as governor of Tokyo against Minobe, but Mishima had no intention of becoming a politician.
