Kenpō Kaigi

In 1965, the Kenpō Kaigi (憲法会議　憲法改悪阻止各界連絡会議) was founded by intellectuals, including a constitutional scholar, Yasuzō Suzuki, who led a non-government constitutional research group organized in 1945, looking for a new constitution for post-war Japan; this group published a draft in December 1945, which highlighted popular sovereignty and had some fundamental similarities with the GHQ draft that underlay the Constitution of Japan.

Opposing constitutional revision, their website publishes statements and information of publications and events. The group's stated intent is to spread awareness about the constitution in order to prevent revision, build connections among like-minded groups/people, and promote anti-revision movements.
