Takeo Fukuda (福田 赳夫, Fukuda Takeo; 14 January 1905 – 5 July 1995) was a Japanese politician who served as prime minister of Japan from 1976 to 1978.

Born in Gunma Prefecture and educated at Tokyo Imperial University, Fukuda served as an official in the Ministry of Finance for two decades before entering politics. He was first elected to the Diet in 1952, and served as agriculture, forestry, and fisheries minister in 1959–1960 under Nobusuke Kishi, as head of the party's political affairs section under Hayato Ikeda, and as finance minister (1965–1966, 1968–1971) and foreign minister (1971–1972) under Eisaku Satō, becoming his protégé. Fukuda's political life was marked by a rivalry with Kakuei Tanaka, who succeeded Satō as prime minister in 1972 and under whom Fukuda served as finance minister from 1973 to 1974. As prime minister from 1976, Fukuda formulated the Fukuda Doctrine, which pledged trust and cooperation with Asian countries, and concluded the Treaty of Peace and Friendship between Japan and China in 1978. He was succeeded as premier in 1978 by Masayoshi Ōhira.

Zenkō Suzuki (鈴木 善幸, Suzuki Zenkō; 11 January 1911 – 19 July 2004) was a Japanese politician who served as prime minister of Japan from 1980 to 1982.

Born in Iwate Prefecture, Suzuki graduated from the Tokyo University of Fisheries in 1935 and was elected to the Diet in 1947 as a member of the Japan Socialist Party, then shifted rightward and joined the Liberal Democratic Party. He briefly served as posts and telecommunications minister and cabinet secretary under Hayato Ikeda, as health and welfare minister under Eisaku Satō, and as agriculture, forests, and fisheries minister under Takeo Fukuda. After the sudden death of prime minister Masayoshi Ōhira in 1980, Suzuki assumed leadership of his faction, and he succeeded him as LDP president and prime minister until 1982.
