Thai PBS Verify discovered a video on Threads, posted by user ‘socraticvibes‘ on March 22, 2026. The footage was originally shared on Instagram by a user ‘unfoldingbharat’ on March 21, 2026, and contains the following script:
“More than 10,000 protesters gathered outside Japan’s National Diet building in Tokyo on the night of March 19, 2026 in one of the country’s largest anti-war demonstrations in recent years, voicing strong opposition to Prime Minister Sanae Takaichi’s push to revise Japan’s pacifist constitution and deploy long-range missiles in alignment with Washington’s strategic posture in the region. The protest was timed to coincide with Takaichi’s summit meeting with US President Donald Trump held the same day, a gathering that demonstrators said represented exactly the kind of uncritical alignment with American foreign policy that they were marching against. Protesters carried signs reading No War and messages opposing Japanese military expansion and what many described as excessive deference to Washington’s geopolitical agenda. The crowd, which gathered peacefully with glow sticks visible throughout the demonstration, chanted slogans including Japan’s future is not in Washington reflecting widespread public anxiety about the country being drawn into the expanding US-Iran conflict. An Asahi Shimbun poll conducted on March 14 and 15 found that 82 percent of Japanese citizens oppose the United States attack on Iran, one of the strongest readings of public anti-war sentiment recorded in Japan in the post-war era. Japan’s pacifist constitution, adopted after World War Two, has long been a source of national identity and the prospect of its revision to allow offensive military capabilities including long-range missile deployment has consistently faced significant public resistance. The protests have been reported by Xinhua, the Christian Science Monitor and multiple Japanese media outlets. Prime Minister Takaichi has not issued a direct public response to the demonstration at the time of…”

高市・トランプ会談直前のタイミングで、総がかり行動が呼びかけた「イラン攻撃許さない！高市政権から平和憲法を守り生かす 3.19国会議員会館前行動」。
大勢集まるとは予想していましたが、ここまでとは。ついに、二重のペンライトの帯が出現しました。
議員会館側の歩道が溢れたため、国会議事堂側の歩道にも参加者が流れていました。今日も若い世代の参加が目立ちます。
ペンライトの波は議員会館前と一部国会議事堂側、国会図書館前、そして自民党本部方向にも延びていました。
後半で参加者からのスピーチも。
「弟は自衛隊員。親の暴力から守ってくれたこともある。彼が誰かを殺すことも殺されることもあってはならない。子どもの頃、家に帰ると今日は弟が殺されているのではないかと思ってきた。生き残れたが、また弟の命を毎日心配している。戦争は避ける以外にない。最小限の被害に抑えられる戦争などない。自衛隊の派遣に反対。改憲に反対」
議員会館前での「19日行動」としては過去最高の11,000人と主催者発表がありました。なんとか、23時からの日本テレビの『ニュースZERO』が参加者のコメントも含めて報じました。
◆もう本日ですが、3月20日（金・休）17時～18時、新宿駅東南口広場にて「トランプ・高市会談翌日アクション」を行います。呼びかけはイラン攻撃をやめろ！緊急アクション、STOP大軍拡アクション、武器取引反対ネットワーク（NAJAT）です。
It could be translated with the aid of Google Translate as follows:
“Strongly oppose any attacks on Iran!
Stop being a puppet of the United States!
Oppose the constitutional amendment!
Firmly oppose all arms exports!
Strongly oppose the anti-espionage law!
The reactivation of nuclear power plants is unacceptable!
Stop the deployment of long-range missiles!
No reduction in parliamentary seats!
“Shortly before the meeting between Takaichi and Trump, an activist group issued a mobilization call: ‘We will not allow an attack on Iran! Protect and uphold the Peace Constitution against the Takaichi administration! Join the March 19 action in front of the Diet Members’ Office Building
“We expected a large turnout, but we never imagined it would be this massive. Eventually, a group carrying dual-beam flashlights emerged.
The sidewalks surrounding the Diet Members’ Office Building were packed to capacity, causing the crowd to spill over to the pavement facing the National Diet Building itself. Today’s turnout was particularly notable for the high number of young people in attendance.
“The beams from the flashlights cast a wide glow, stretching from the front of the Diet Members’ Office Building to parts of the National Diet Building, the National Diet Library, and even as far as the Liberal Democratic Party (LDP) headquarters. During the latter half of the event, participants also delivered a series of speeches.
“‘My younger brother is a member of the Self-Defense Forces. He was the one who protected me from our parents’ violence. He must never be allowed to kill, nor should he be killed. When I was young, I lived in constant fear, wondering if my brother would lose his life that day. Although he survived, I still worry about his safety every single day. There is no such thing as an unavoidable war, and no war can ever be ‘minimized.’ I stand firmly against the deployment of the Self-Defense Forces and the constitutional amendment.’
“Organizers announced that the ‘March 19 Rally’ in front of the Diet Members’ Office Building drew 11,000 participants—the highest turnout on record. The event, including testimonials from attendees, was featured on Nippon Television’s ‘News ZERO’ program during its 11:00 PM broadcast.
“◆ On Friday, March 20—a public holiday—a rally titled ‘Meeting Following the Trump-Takaichi Summit’ will take place from 5:00 PM to 6:00 PM at the Southeast Exit of Shinjuku Station. The call for this gathering comes from a coalition including ‘Stop the Attack on Iran! Emergency Action,’ ‘STOP Massive Military Expansion Action,’ and the ‘Network Against Arms Trade (NAJAT).’”

What do the Japanese think about developments in the Iran war?
Monitoring the ongoing developments within Japan, Thai PBS Verify has identified a report published by the Asahi Shimbun on March 24, 2026.
The following is the key details:
A news report from the Asahi Shimbun website, published on March 24, 2026
“On March 23, 2026, approximately 50 high school students from the group ‘Tokyo Kokosei Heiwa Seminar’ gathered near the U.S. Embassy in Tokyo to protest against potential military strikes on Iran by the United States and Israel. The youth activists held up signs calling for a shift from military force to diplomatic dialogue, while also voicing their criticism of the situation as they criticized President Trump for interfering in international politics and using democracy as a pretext to justify the use of force. Such actions, they argued, constitute a grave violation of international law.
“Student leaders, aged 17, from various prefectures across Japan—including Okinawa and Hiroshima—jointly read a protest statement. They underscored the vital importance of peace and expressed deep disappointment in global powers for resorting to military strikes. Furthermore, the group criticized the Japanese government for being overly submissive to U.S. interests, urging Japan to find the courage to say ‘no’ to prevent a prolonged war and to protect the lives of innocent civilians and children in conflict zones.”
What is the truth?
Thai PBS Verify found that the video and information regarding the protest were real. The event took place on the night of March 19, 2026, in front of the National Diet Building and the Diet Members’ Office Buildings in the Nagatacho district of Tokyo.
Approximately 11,000 protesters gathered to voice their opposition to Prime Minister Sanae Takaichi’s military policies, specifically the efforts to amend Article 9 of the ‘Peace Constitution’ and the deployment of long-range missiles. The demonstrators view these moves as a strategic shift driven by U.S. interests under the Trump administration, particularly amidst the escalating conflict between the U.S.-Israel alliance and Iran.
