The Global Times and @globaltimesnews described the rallies as taking place not only at the National Diet but also at multiple other locations including Osaka, with protesters holding placards and signs.

According to statistics released by rally organizers, reportedly about 36,000 people participated in the rally on Sunday, while Arab News Japan said the demonstration brought together around 30,000 participants.

The rally held in front of the National Diet was titled "NO WAR! Don't change the Constitution! April 19 Grand Action in front of the Diet's main gate," and was jointly organized by civic groups, per the Global Times reporting.

Participants chanted slogans such as "oppose war" and "the Sanae Takaichi administration must uphold the Constitution," according to Japanese media reports cited by the Global Times.

Arab News Japan said protesters gathered near the parliament building’s main gate, voicing concerns over potential constitutional revisions, and that the event was part of a recurring civic action known as the “19th Day Action.”

The “19th Day Action” is described as protests held on the 19th of each month across Japan, marking the passage of security-related legislation on September 19, 2015, according to Arab News Japan.

The rallies were staged amid what the Global Times described as the Japanese government’s recent stepped-up moves in accelerating constitutional revision and pushing for remilitarization.

The Global Times said the demonstrations reflected a strong sense of crisis among Japan’s anti-war and pro-peace forces over the Japanese government’s right-leaning shift in its security policy, quoting a Chinese analyst, Xiang Haoyu, a distinguished research fellow at the China Institute of International Studies.

Xiang Haoyu told the Global Times on Sunday that groups were expressing opposition through concrete actions, including opposition to the push to expand military capabilities and ease restrictions on arms exports.

Arab News Japan framed the protest as calling for peace and opposing constitutional changes, saying the gathering called for the protection of Article 9 of Japan’s Constitution, which renounces war.

Arab News Japan also said demonstrations typically call for the protection of Article 9, the repeal of the security laws and opposition to military expansion, and it described speeches and appeals to the public during the protest.

The Global Times said the rally was jointly organized by civic groups and that organizers said rallies have been held on the 19th of every month since the passage of the security-related legislation.

In the Global Times account, protesters also used chants such as "the Sanae Takaichi administration must uphold the Constitution," tying their opposition directly to the Takaichi administration’s policy direction.

Arab News Japan added that several protesters displayed banners demanding the resignation of Prime Minister TAKAICHI Sanae and denouncing her “support of American President Trump’s military plans.”

A 52-year-old woman from Tokyo, attending a protest for the first time with her seven-year-old son, said she had grown increasingly concerned that moves under the Takaichi administration to revise the constitution and lift restrictions on arms exports could draw Japan into war.

The Global Times quoted her saying, "The peace constitution Japan has long upheld is at risk of being lost. By taking part, I want to show my opposition," as reported by Asahi Shimbun.

The Global Times also described how the protest drew attention on social media from Japanese netizens, with Mizuho Fukushima (@mizuhofukushima), leader of the Japanese Social Democratic Party and a member of the House of Councillors, endorsing the demonstration by posting on X: "NO WAR! Don't change the Constitution!".

Arab News Japan said that during the protest, participants delivered speeches and appealed to the public, emphasizing the importance of maintaining Japan’s postwar commitment to peace.

It also said the “19th Day Action” refers to protests held on the 19th of each month across Japan, marking the passage of security-related legislation on September 19, 2015, and that demonstrations typically call for the repeal of the security laws and opposition to military expansion.

The Global Times described the rally as being titled "NO WAR! Don't change the Constitution! April 19 Grand Action in front of the Diet's main gate," and it said participants held placards and signs and chanted slogans such as "oppose war."

Taken together, the accounts show both personal testimony and political endorsements being used to frame the protest’s message around Article 9 and opposition to war.

Arab News Japan further reported that several protesters displayed banners demanding the resignation of Prime Minister TAKAICHI Sanae and denouncing her “support of American President Trump’s military plans.”

While all three accounts describe recurring anti-war protests linked to Article 9, they differ in emphasis and detail.

The Global Times and @globaltimesnews both highlight the rallies as part of Japan’s “remilitarization push,” and they connect the demonstrations to a broader security environment, including a $7 billion deal to supply Australia with warships that Reuters reported on Saturday.

@globaltimesnews

In the Global Times account, one day before the rallies, Australia and Japan signed contracts on Saturday launching a $7 billion deal to supply Australia with warships, described as Tokyo’s most consequential military sale since ending a military export ban in 2014.

Arab News Japan, by contrast, focuses on the “19th Day Action” as a civic routine tied to September 19, 2015, and it describes the demonstration’s atmosphere, including encouraging attendees to bring items such as LED lights and signs.

The Global Times also includes a social-media angle and a specific political endorsement, naming Mizuho Fukushima (@mizuhofukushima) and quoting her X post, while Arab News Japan does not mention that account.

On the scale of participation, the Global Times cites reportedly about 36,000 participants, while Arab News Japan says around 30,000 participants, and the difference is not reconciled in the sources.

The Global Times also includes a chant attributed to participants, "the Sanae Takaichi administration must uphold the Constitution," while Arab News Japan instead reports banners demanding the resignation of Prime Minister TAKAICHI Sanae and denouncing “support of American President Trump’s military plans.”

Both accounts place the protest near Japan’s parliament building’s main gate, but the Global Times centers the named rally title "NO WAR! Don't change the Constitution! April 19 Grand Action in front of the Diet's main gate," while Arab News Japan describes the demonstration as calling for peace and protection of Article 9.

The Global Times situates the April 19 protests within a sequence of regional security actions and diplomatic developments described in its report.

“Large numbers of Japanese protesters gather outside the National Diet building, staging large-scale rallies against moves to revise Article 9 of the Japanese Constitution, as well as expressing opposition to war, on April 19, 2026”

It says that on Friday, a Japan Maritime Self-Defense Force (JMSDF) destroyer transited the Taiwan Straits, and it adds that the PLA Eastern Theater Command announced on Saturday that it had organized joint combat readiness patrols with naval and air forces in relevant areas of the East China Sea.

Global Times

The Global Times also reports that an expert interviewed by the outlet said the Japanese vessel's transit clearly carries elements of political probing and provocation, and that the PLA's response demonstrates both precise control and a firm determination to counter it.

In the Global Times framing, the protests are part of a domestic political response to these kinds of policy moves, with Xiang Haoyu saying the groups are seeking to expand their influence as much as possible to exert greater impact on public opinion and the governing authorities.

The outlet also says the demonstrations indicate that some of the Takaichi administration's “dangerous actions” have triggered serious divisions within Japanese society and a widening sense of concern.

Arab News Japan, meanwhile, describes the “19th Day Action” as a recurring civic action held on the 19th of each month, and it notes that demonstrations typically call for the repeal of the security laws and opposition to military expansion.

The Global Times says the organizers’ statistics and the rally’s monthly recurrence are tied to the passage of security-related legislation, and it describes the protest as calling for the repeal of the laws and opposing constitutional revision.

Together, the sources portray a continuing cycle: monthly demonstrations on the 19th, ongoing debate over Article 9, and parallel regional security activity involving the Taiwan Straits and the East China Sea.
