Japan's centrist opposition alliance collapses, leaving fragmented challenge to ruling LDP
The eight-month-old Centrist Reform Alliance has dissolved, with Komeito lawmakers returning to their party and CDPJ members considering a new venture, deepening opposition fragmentation ahead of elections.
After roughly eight months, the Centrist Reform Alliance—created by lawmakers from the Constitutional Democratic Party of Japan and Komeito—has officially split, with Komeito representatives rejoining their former party and CDPJ members exploring a new political project. The breakup follows a disappointing showing in the last general election, where the alliance’s seats fell dramatically, and an inability to reconcile divergent security and energy positions.
Party leader Junya Ogawa cited the difficulty of pursuing a long-term merger within a short election cycle as a key obstacle. Scholars argue the alliance was misaligned from the start and that its planned parliamentary caucus may appear half-hearted. The dissolution is expected to leave the opposition fragmented, bolstering Prime Minister Sanae Takaichi’s ruling coalition ahead of upcoming local elections and the 2028 House of Councillors race.
