ELECTORAL SYSTEM

Parliament name (generic / translated) Kokkai / National Diet
Structure of parliament Bicameral
Chamber name (generic / translated) Shugiin / House of Representatives
Related chamber (for bicameral parliaments) Sangiin / House of Councillors
LEGAL FRAMEWORK
Electoral law 15 April 1950
Last amendment: 27 May 2016
Mode of designation directly elected 465
Constituencies - 289 single-member constituencies (majority system)
- 11 multimember (6 to 28 seats) constituencies (proportional representation system) for 176 seats
Voting system Mixed: Mixed system:
- simple majority vote in 289 single-member constituencies
- party list under the proportional representation system using the d'Hondt method for the remaining 176 seats, with allocation of seats based on the parties' share of the national vote in the 11 large districts.
Candidates may run in both the single-seat constituencies and the proportional representation poll. However, these so called "duplicate" candidates are only allowed to run for the proportional representation block in which their single- seat constituency is located.
Each party's proportional representation list includes candidates who take part in the proportional representation poll alone, adding up to the set number of seats for each bloc plus duplicate candidates from single-seat constituencies.
Candidates running in single-seat constituencies must obtain at least one-sixth of all valid votes to obtain a seat.
Vacancies for members elected under the proportional representation system are filled by the "next-in-line" candidate of the same party, regardless of the number of votes obtained. However, in the case of duplicate candidates, the number of votes obtained must be higher than the statutory number of votes, i.e. one-tenth of all valid votes.
By-elections are held if seats occupied by members elected from single-seat-constituencies become vacant. They are held twice a year, in April and October.
Voting is not compulsory.
Voter requirements - age: 18 years

- deposit of 6 million yen for each candidate on the list of a political party, or 3 million yen if that candidate is also running for a single-seat constituency, forfeited according to the formula given below.

In addition, political parties and organizations are encouraged to voluntarily set numerical targets for male and female candidates for public posts.

LAST ELECTIONS

Parliament name (generic / translated) Kokkai / National Diet
Structure of parliament Bicameral
Chamber name (generic / translated) Shugiin / House of Representatives
Related chamber (for bicameral parliaments) Sangiin / House of Councillors
BACKGROUND
Dates of election / renewal (from/to) 22 October 2017
Timing and scope of renewal 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.
