The Centrist Reform Alliance was formed in January to counter the ruling coalition, led by Prime Minister Sanae Takaichi
1-MIN READ1-MINKyodoPublished: 10:03am, 31 Aug 2026Japan’s centrist opposition alliance stood on the brink of falling apart on Monday, with sources saying members who joined from the Komeito party just months ago could leave the group.The development follows the collapse of talks on the incorporation by the Centrist Reform Alliance of members of Komeito and the Constitutional Democratic Party of Japan (CDPJ) in a three-way merger to counter the ruling coalition, led by Prime Minister Sanae Takaichi.The leaders of the three opposition parties are scheduled to meet later in the day to make a formal decision regarding the merger plan.
Komeito and CDPJ lawmakers continue to sit separately in the House of Councillors, in which the ruling coalition does not hold a majority.
The focus will now shift to the opposition parties’ future cooperation ahead of unified local elections next year, with political analysts saying the fragmentation of the opposition camp will benefit the ruling parties.
After months of talks, CDPJ leader Shunichi Mizuoka said in a meeting with his counterparts from the CRA and Komeito on Friday that his party would not join the alliance.
His call for exploring new forms of cooperation, such as forming a joint caucus in the upper house, was rejected by a senior Komeito executive.
