Ruling coalition • The
Liberal Democratic Party (LDP), the
conservative party led by Prime Minister
Shinzo Abe who has been in power since the
2012 House of Representative election. The LDP currently enjoys the
two-thirds majority with its coalition partner
Komeito which allows the government to push forward the revision of the war-renouncing
Article 9 of the Japanese Constitution. •
Komeito, a nominally
Buddhist party led by
Natsuo Yamaguchi, is the junior coalition partner of the incumbent government. Holding 35 seats in the House of Representatives, the party is considered as
social conservative and closely associated with the
Soka Gakkai religious movement.
Koike's coalition •
Kibō no Tō, also known as the Party of Hope, is the brand new conservative reformist party launched by
Yuriko Koike, former LDP minister and incumbent
governor of Tokyo, on 25 September 2017 ahead of the general election. The new party attracted former members of the LDP as well as the conservative wing of the
Democratic Party, the largest opposition party at the time, led by
Seiji Maehara to join with the aims of overthrowing the Abe government. Three members of the
Ichirō Ozawa's
Liberal Party also decided run under Koike's banner. Despite being tipped as the first Japan's woman Prime Minister, Koike has expressed no intention to run in the general election and stated that her party would not name a prime ministerial candidate during the election. The party has promised to freeze the planned consumption tax increase and promote debate on the constitutional revision. •
Nippon Ishin no Kai, previously known as Initiatives from Osaka, is a
Kansai-based party led by Governor of Osaka
Ichirō Matsui. It split from the
Japan Innovation Party in 2015. Having similar policies with Kibō no Tō, the party has agreed to cooperate with Koike in the coming election.
Pacifist coalition • The
Japanese Communist Party (JCP), the
left-wing party led by
Kazuo Shii, saw its recent resurgence in the
2014 House of Representative election due to its firm
pacifist stance against the revision of Article 9 of the Constitution. The party currently is the second largest opposition party, holding 21 seats in the House of Representatives. The party forms an alliance with two other left-leaning parties, the Constitutional Democrats and the Social Democrats, and plans to field 243 candidates. • The
Constitutional Democratic Party of Japan (CDP), a brand new
centre-left social liberal party formed by
Yukio Edano on 2 October 2017 by the liberal wing of the Democratic Party, the then largest opposition party, after Kibō no Tō refused to nominate the liberal candidates of the Democratic Party when the party leader Seiji Maehara decided to join Kibō no Tō with the party. The party calls for Japan to phase out
nuclear power, opposes the constitutional revision and the
new national security legislation with two other left-leaning opposition parties. The party plans to field 78 candidates in the coming election. • The
Social Democratic Party (SDP) is the centre-left
social democratic party led by
Tadatomo Yoshida, which currently holds 2 seats in the House of Representatives. It opposes the revision of the pacifist Article 9 of the Constitution, and forms an alliance with two other left-leaning to stop the constitutional revisionists from winning a two-thirds majority.
Other parties • The
Party for Japanese Kokoro (PJK), formerly called the
Party for Future Generations, currently holds no seat in the House of Representatives after its two members left to rejoin the Liberal Democratic Party in 2015. It is led by
Masashi Nakano after its former leader
Kyoko Nakayama left to join Kibō no Tō in late September and provides
confidence and supply to the Abe cabinet. The party was formed by the
right-wing nationalist wing led by
Shintarō Ishihara who split from the
Japan Restoration Party in 2014.
