Tens of thousands of people gathered outside Japan’s parliament in Tokyo on April 8 to protest against the US-‘Israeli’ war on Iran, as the proposed changes to Japan’s constitution continue to gain momentum across the country.
Organizers said around 30,000 demonstrators assembled near the National Diet Building, marking a steady increase in turnout compared to earlier protests in recent weeks. Simultaneous actions were also reported in 137 locations nationwide, reflecting a broadening movement opposing revisions to Japan’s pacifist constitution.

The rally, titled “Emergency action to protect the Peace Constitution,” was organized by citizen groups including We Want Our Future and the Don’t Destroy Article 9 Executive Committee. Participants from a wide range of age groups filled the streets, waving lights and chanting slogans such as “The pacifist Constitution is Japan’s treasure” and “No to constitutional revision.”
At the center of the protests is Article 9 of Japan’s constitution, which renounces war and prohibits the country from maintaining armed forces for combat. Activists fear that proposed revisions could erode these protections and open the door to expanded military activity.
Speakers at the rally included educators and peace advocates, who called on political leaders to uphold constitutional principles and warned against what they see as a shift toward militarization.

Participants also expressed concern over policies associated with Prime Minister Sanae Takaichi, including proposals to revise Japan’s non-nuclear principles and ease restrictions on weapons exports.
A protester from Tokyo said she feared that constitutional changes could have far-reaching consequences. “If the Constitution is revised, we will no longer be able to speak out,” she said, adding that she was worried about the possibility of conscription becoming a reality.
The demonstrations are part of a growing nationwide movement, with rising turnout suggesting increasing public engagement on the issue. Protesters say they will continue mobilizing to defend what they describe as the foundations of Japan’s postwar peace framework.
