Japan's centrist opposition bloc teeters on split as Komeito members reconsider

Japan's centrist opposition alliance, created in January, is nearing a breakup after reports that Komeito legislators who joined the bloc a few months earlier may leave. The collapse of negotiations to merge the Centrist Reform Alliance with Komeito and the Constitutional Democratic Party of Japan has led the three party leaders to meet later in the day to decide the alliance's fate. The coalition controls 49 seats in the House of Representatives, comprising 28 Komeito and 21 CDPJ members, while both parties sit apart in the House of Councillors, where the ruling coalition does not command a majority.

The ruling Liberal Democratic Party and its partner, the Japan Innovation Party, dominate the lower house. Opposition strategist Shunichi Mizuoka announced his party will not join the alliance, proposing instead a joint upper-house caucus, a suggestion rejected by a senior Komeito official. Analysts warn that a fragmented opposition could advantage the governing parties ahead of next year’s unified local elections.
