Three opposition parties in Japan are exploring the formation of a new political party, according to sources familiar with the matter. The talks involve the Centrist Reform Alliance, the Constitutional Democratic Party of Japan, and Komeito.
The idea emerged from discussions about integrating the three parties into a single entity. Both the Centrist Reform Alliance and Komeito support the new party option, sources said.
Support for the merger extends beyond the party leaderships. Senior members of the Constitutional Democratic Party and officials from a major labor union backing the initiative have also expressed support, according to sources familiar with the discussions.
No formal announcement has been made about the merger timeline or structure. The three parties continue to explore how such an alliance might function and what form it would take.
The move would reshape Japan's opposition landscape by consolidating three separate parties into one larger force. Details about how the integration would work have not yet been disclosed.
