Hayato Ikeda
In 1947, Ishida was elected to the House of Representatives. He joined the Liberal Democratic Party (LDP) in 1955, serving as Chief Cabinet Secretary under two prime ministers, Tanzan Ishibashi and Nobusuke Kishi, from 23 December 1956 to 10 July 1957. Widely viewed as a friend and proponent of labor unions (an unusual stance in the pro-business LDP), he was also appointed to five terms as Minister of Labor under four different prime ministers, in addition to one term as Minister of Transport. While Minister of Labor under Prime Minister Hayato Ikeda in 1960, Ishida successfully negotiated the end of the 1960 Miike Coal Mine Strike, which remains the largest labor-management dispute in Japanese history.
