Since the
Meiji Restoration in which lower-rank nobility from
Chōshū played a major role, many politicians from Yamaguchi have held important positions in national politics. In the post-war era, the most prominent political family from Yamaguchi is the
Kishi-
Abe/
Satō prime ministerial dynasty, and Yamaguchi is leaning solidly towards the
Liberal Democratic Party (LDP).
Delegation to the National Diet Since the electoral reform of the 1990s, Yamaguchi elects four members directly to the
House of Representatives. Three of the new single-member districts have been held exclusively by Liberal Democrats as of 2013, the easternmost district bordering
Hiroshima was initially won by
Shinji Satō (Eisaku Satō's son) in 1996, but went to
Democrat Hideo Hiraoka in several later elections. Currently, following the 2021 general election, Yamaguchi's directly elected delegation to the lower house consists of former LDP vice president
Masahiko Kōmura (
1st district, 12th term), the chairman of the foreign affairs committee,
Nobuo Kishi (2nd district, 2nd term, former two-term member of the House of Councillors), and the chairman of the House of Representatives rules committee (as of 190th Diet, January 2016),
Yoshimasa Hayashi (3rd district, 1st term). The seat for the 4th district was held by former prime minister
Shinzo Abe until his
assassination in 2022, and is currently vacant. For the proportional representation segment of the House of Representatives, Yamaguchi forms part of the
Chūgoku block. In the
House of Councillors, Yamaguchi is represented by two members, making it one of the currently 31 winner-take-all single-member districts. As of 2013, the two members are
Yoshimasa Hayashi (LDP, 4th term, up in 2019), agriculture minister in the 2nd Abe Cabinet, and following the April 2013 by-election to replace Nobuo Kishi,
