About the election Short description of the context and results of the election.
Prime Minister Shinzo Abe's ruling coalition - comprising his Liberal Democratic Party (LDP) and Komeito - retained its two-thirds majority in the early elections, taking a total of 335 seats in the 465-member House of Representatives (see note 1). The Constitutional Democratic Party of Japan, led by former Chief Cabinet Secretary, Mr. Yukio Edano; and Kibo no To (Party of Hope), led by the Governor of Tokyo, Ms. Yuriko Koike, took 54 and 50 seats respectively (see note 2). The percentage of women in the House of Representatives surpassed 10% for the first time since 2009. On 1 November, Mr. Abe was re-elected as Prime Minister. The 2017 elections were held amid security threats caused by missile launches and nuclear testing by the Democratic People's Republic of Korea (DPRK). The Prime Minister called snap elections in late September, stating that he needed a fresh mandate for his administration's handling of the tensions with the DPRK as well as for its decision to spend more revenue from the planned rise in consumption tax (from 8 to 10% in 2019) on social welfare and less on paying off government debt. Most opposition parties opposed the consumption tax increase. The major electoral issues included the Prime Minister’s plan to amend the Constitution, while the evaluation of the second Abe administration (since 2012) also dominated the election campaign. Among the major parties, the ruling coalition and Kibo no To advocated for constitutional amendments while the Constitutional Democratic Party of Japan opposed them. Note 1: In accordance with amendments to the Electoral law promulgated on 27 May 2016, the number of single-member constituencies decreased from 295 to 289, and the number of members elected under the proportional system fell from 180 to 176. Accordingly, the number of members of the House of Representatives has been reduced from 475 to 465. Note 2: Prior to the 2017 elections, the main opposition Democratic Party (which itself had been formed in March 2016 by the Democratic Party of Japan and two other parties) split into several parties. Most members joined Kibo no To, formed by Governor Koike, who herself did not stand for the 2017 elections. Fifteen other members joined the Constitutional Democratic Party of Japan, while Democratic Party leader Seiji Maehara and other senior members ran as independents.
