The 27th general election of the House of Councillors is scheduled to be held in Japan by 27 July 2025 to elect 124, half of the 248 members of the House of Councillors, the upper house of the National Diet, for a term of six years.[1][2]

Background

[edit]

The October 2024 general election resulted in the loss of majority of the Liberal Democratic Party-Komeito governing coalition in the House of Representatives under Prime Minister Shigeru Ishiba,[3] with the possibility of the ruling coalition suffering another "major defeat" at the House of Councillors election if opposition parties unite their candidates.[4]

According to Jiji Press, if five opposition parties, including the main opposition Constitutional Democratic Party of Japan (CDP), make deals in the 32 single-seat constituencies, the ruling LDP-Komeito coalition is projected to win 10 seats against the opposition camp's 22, and only three if the Nippon Ishin no Kai, also known as the Japan Innovation Party, joins the opposition alliance.[4]
