Former members of the centrist reform coalition announced the creation of a new political organization called “護憲リベラル共生,” or “Gorilla,” on Aug. 19 [3].

The move represents an attempt to regroup the liberal opposition following a significant electoral setback earlier this year. The founders of the new group were defeated in the House of Representatives election in February 2026 [2].

Co-representative Hiroshi Kawauchi said the group was established to conduct politics that protects peace, the Constitution, and the livelihoods of all citizens. He said the organization intends to gather all people who can unite under the banner of constitutional liberalists.

According to the group's announcement, the organization will focus on protecting the Constitution, with a specific emphasis on Article 9 [1]. The group also aims to promote peace, and safeguard the general welfare of citizens [1].

Beyond constitutional protections, the group is pursuing specific institutional reforms. A policy statement from the group called for a further revision of the Imperial Household Law to allow for primogeniture succession [1].

The new organization has already attracted interest from within the Japanese legislature. Sixteen current Diet members have expressed their intent to join the group [1].

Kawauchi and co-representative Tomoko Abe led the initiative to form the organization. The group's formation follows a period of fragmentation among centrist and liberal forces in Japan's national political arena [1, 2].

“"I created this organization to conduct politics that protects peace, the Constitution, and the livelihoods of all citizens."”

The formation of 'Gorilla' suggests a strategic pivot by defeated centrist candidates to build a broader liberal coalition outside their previous party structures. By combining traditional constitutional protections with specific reforms like Imperial primogeniture, the group is attempting to bridge the gap between strict constitutionalists and those seeking modernization of the monarchy to maintain a viable opposition presence in the Diet.
