the prime minister may dissolve the chamber at any time for a snap election[2](https://www.cambridge.org/core/journals/japanese-journal-of-political-science/article/dyadic-representation-in-parliamentary-democracy-in-japan/0ACE921C52C8DD64C535D207733D17E9) |\n| Current lower-house balance | Liberal Democratic Party 316 seats (after one independent joined);

each voter casts two votes, one for a constituency candidate and one for a party list.[2](https://www.cambridge.org/core/journals/japanese-journal-of-political-science/article/dyadic-representation-in-parliamentary-democracy-in-japan/0ACE921C52C8DD64C535D207733D17E9) • [5](https://www.courts.go.jp/english/Judgments/search/1919/index.html) The two tiers are insulated from each other: unlike German or New Zealand mixed systems, proportional seats are not used to correct the overall seat total toward a party's list vote share.[6](https://www.cambridge.org/core/journals/japanese-journal-of-political-science/article/electoral-incentives-policy-compromise-and-coalition-durability-japans-ldpkomeito-government-in-a-mixed-electoral-system/D153792B61853FAC9AF38A20E5076D32)\n\nConstituency boundaries have been the subject of repeated constitutional litigation over vote-value inequality. In a Grand Bench judgment of 25 January 2023, the Supreme Court ruled that the demarcation in force at the 31 October 2021 election could not be said to violate the constitutional requirement of equality in the value of votes, following a 2022 amendment that had reduced the disparity.[5](https://www.courts.go.jp/english/Judgments/search/1919/index.html)\n\n## Timing and dissolution\n\nA general election occurs either when the four-year term expires or when the prime minister dissolves the House. In practice, dissolution is the norm: Prime Minister Shigeru Ishiba dissolved the House on 9 October 2024 for an election on 27 October, a year ahead of schedule, and Prime Minister Sanae Takaichi dissolved it on 23 January 2026 for an election on 8 February, more than two years early.[1](https://data.ipu.org/parliament/JP/JP-LC01/election/JP-LC01-E20260208/) • [7](https://apnews.com/article/6e7ffd74ff17e263b8aea1283f0afbe8) The 2026 dissolution produced a 16-day campaign period, the shortest since World War II.[8](https://www.youtube.com/watch?v=wXzj8pMty5w)\n\n**The 2026 baseline.** The next election will be contested against the result of the February 2026 snap election, in which Takaichi's Liberal Democratic Party won 315 seats, up from 191 in 2024, securing a two-thirds majority on its own; one independent member later joined, bringing the party to 316.[1](https://data.ipu.org/parliament/JP/JP-LC01/election/JP-LC01-E20260208/) • [9](https://apnews.com/article/bbb322b4dc1dcad8f7373ba7aae4d535) The coalition partner Nippon Ishin ([Japan Innovation Party](https://www.edgepedia.org/japan-innovation-party)) won 36 seats, giving the ruling coalition 352 in total.[4](https://global.nomura-am.co.jp/latest-news/pdf/ecv20260209_02.pdf) The main opposition alliance, the [Centrist Reform Alliance](https://www.edgepedia.org/centrist-reform-alliance) formed by the [Constitutional Democratic Party of Japan](https://www.edgepedia.org/constitutional-democratic-party-of-japan) and Komeito, fell to 49 seats, and its leader Yoshihiko Noda resigned afterward.[1](https://data.ipu.org/parliament/JP/JP-LC01/election/JP-LC01-E20260208/)\n\nThe election drew 1,284 candidates from 12 parties, of whom 313 (24.4%) were women; 68 women were elected, 14.6% of the chamber, down from 72 (15.5%) in 2024.[1](https://data.ipu.org/parliament/JP/JP-LC01/election/JP-LC01-E20260208/) • [10](https://www.idea.int/democracytracker/report/japan/february-2026) Turnout was 56.3%, up from 53.8% in 2024.[1](https://data.ipu.org/parliament/JP/JP-LC01/election/JP-LC01-E20260208/) • [11](https://ejpr.onlinelibrary.wiley.com/doi/10.1111/2047-8852.70031)\n\n## What shapes the next contest\n\n**Chamber arithmetic.** The LDP's two-thirds majority in the lower house does not extend to the upper house, where the party remains in the minority until the next House of Councillors election around July 2028; bills rejected by the upper house can still be passed by a two-thirds vote of members present in the lower house.[4](https://global.nomura-am.co.jp/latest-news/pdf/ecv20260209_02.pdf) The upper-house election in 2028 is therefore the intervening national vote that will set the stage for the general election that follows.\n\n**Party configuration.** The 2026 election produced a nine-party lower house, with the Democratic Party for the People on 28 seats, Sanseito on 15, and [Team Mirai](https://www.edgepedia.org/team-mirai) on 11 alongside the larger blocs.[1](https://data.ipu.org/parliament/JP/JP-LC01/election/JP-LC01-E20260208/) The opposition entered that contest reorganized: Komeito had left the governing coalition shortly before Takaichi's premiership election in October 2025 and joined Noda's Constitutional Democratic Party in the Centrist Reform Alliance, a bloc that had held 172 seats combined in 2024.[1](https://data.ipu.org/parliament/JP/JP-LC01/election/JP-LC01-E20260208/)\n\n**Campaign issues.** The main issues in 2026 were measures against the rising cost of living, with the major parties proposing cuts to consumption and income taxes.[1](https://data.ipu.org/parliament/JP/JP-LC01/election/JP-LC01-E20260208/) Takaichi's victory was read as a mandate for a conservative shift in security, immigration, and social policy, including revised defense policies by December 2026 and a planned national intelligence agency.[9](https://apnews.com/article/bbb322b4dc1dcad8f7373ba7aae4d535) • [12](https://apnews.com/article/0d87101569c8ae10bca5435a731ae3bf) Whether those policies sustain or erode the governing party's standing is the central uncertainty for the next election's timing and outcome, since the prime minister retains the discretion to dissolve the House well before January 2030.[2](https://www.cambridge.org/core/journals/japanese-journal-of-political-science/article/dyadic-representation-in-parliamentary-democracy-in-japan/0ACE921C52C8DD64C535D207733D17E9)\n\n## References\n\n1.
