As a Diet member, Ishiba specialized in agricultural policy and defense policy. He served as parliamentary vice minister of agriculture under the premiership of Kiichi Miyazawa, but left the LDP in 1993 to join the Japan Renewal Party. After transitioning through several parties and returning to the LDP in 1997, Ishiba held various prominent positions, including Director-General of the Defense Agency under the premiership of Junichiro Koizumi, Minister of Defense under the premiership of Yasuo Fukuda and Minister of Agriculture, Forestry and Fisheries under the premiership of Tarō Asō.

Kishida was appointed to Minister of State for Special Missions in the premiership of Shinzo Abe and Yasuo Fukuda from 2007 to 2008, and was appointed Minister for Foreign Affairs in 2012 after Abe regained the premiership following the 2012 general election, serving for five years and becoming the longest-serving Foreign Affairs Minister in Japanese history. Kishida resigned from the Abe cabinet in 2017 in order to head the LDP's Policy Research Council. Kishida also assumed leadership of the LDP's more moderate Kōchikai faction in 2012 following the retirement of faction leader Makoto Koga, a position he held until his resignation in 2023. Long considered a potential future prime minister, Kishida ran in the 2020 LDP presidential election, but lost to Yoshihide Suga.
