2024 Japanese general election

General elections were held in Japan on 27 October 2024 due to the early dissolution of the House of Representatives, the lower house of the National Diet, by Prime Minister Shigeru Ishiba. Voting took place in all constituencies, including proportional blocks, to elect all 465 members of the House of Representatives.

The majority party, the LDP, was very unpopular among voters because of the 2023–2024 Japanese slush fund scandal. Because of this, the party's coalition partner Komeito lost their parliamentary majority in the lower house for the first time since 2009, with the LDP suffering its second-worst result in its history, winning only 191 seats. The Constitutional Democratic Party (CDP), the main opposition party led by former Prime Minister Yoshihiko Noda, had its best result in its history, increasing its seat count from 96 to 148. This was the first general election in Japan since 1955 where no party won at least 200 seats.

Ishiba was re-elected Prime Minister in the Diet on 11 November as head of an LDP-Komeito minority government.
