The 51st general election of the House of Representatives is scheduled to be held no later than 27 October 2028 to elect all 465 seats of the House of Representatives, the lower house of the National Diet. Voting will take place in all constituencies, including 289 single-seat electoral districts and 176 proportional blocks.^[1]

The 2024 general election resulted in the loss of majority of the Libereal Democratic Party-Komeito governing coalition under Prime Minister Shigeru Ishiba.^[2]

The election will likely take place after:

• 2025 Japanese House of Councillors election (scheduled in summer 2025)

The 465 seats of the House of Representatives are contested via parallel voting. Of these, 289 members are elected in single-member constituencies using first-past-the-post voting, while 176 members are elected in 11 multi-member constituencies via party list proportional representation. Candidates from parties with legal political party-list, which requires either ≥5 Diet members or ≥1 Diet member and ≥2% of the nationwide vote in one tier of a recent national election, are allowed to stand in a constituency and be present on the party list. If they lose their constituency vote, they may still be elected in the proportionally allocated seats. However, if such a dual candidate wins less than 10% of the vote in their majoritarian constituency, they are also disqualified as a proportional candidate.
