Right-Wing Nationalism Goes Mainstream in Post-Pandemic Japan
For decades, Japan’s politics have leaned conservative but largely avoided the populist upheavals reshaping democracies in the West. That era may be over. In a stunning political development, the ultra-nationalist Sanseito party, often compared to Donald Trump’s “MAGA” movement, surged in Japan’s latest upper house elections, multiplying its seats more than sevenfold—from two to 15.
The right-wing party’s meteoric rise highlights a broader global trend: a growing public appetite for populism, anti-elitism, and skepticism toward immigration, globalization, and progressive social norms. In Japan—a country long considered resistant to these trends—Sanseito’s success signals a new chapter in national politics.
Sanseito’s Platform: Japan First, Globalism Last
The Rise of a Homegrown Populism
Sanseito’s ideological playbook mirrors populist movements around the globe. Inspired by Trump’s “Make America Great Again,” Germany’s AfD, and the UK’s Reform Party, Sanseito has branded itself as a voice for “ordinary Japanese citizens” silenced by elites, bureaucrats, and foreign influence.
Party leader Sohei Kamiya, a 47-year-old former teacher and supermarket manager, has positioned Sanseito as the guardian of Japan’s cultural and economic sovereignty. Among its core policies:
-
Stricter immigration controls and limits on foreign workers
-
Opposition to “radical” gender policies and global climate mandates
-
Rejection of foreign capital’s influence in Japanese markets
-
Rethinking vaccine policy and pesticide-free agriculture
-
Strong national identity and cultural preservation
“We will bring power back to the people,” Kamiya wrote recently in the Japan Times. The party, founded just five years ago on YouTube, has managed to convert online engagement into real-world political clout.
Anti-Immigration Sentiment: A New Flashpoint
Sanseito Blames Foreigners for Economic Woes
While surveys show that most Japanese voters are more concerned about inflation and economic insecurity than immigration, Sanseito continues to stoke fears about foreign workers, rising crime, and cultural erosion.
“It’s fine if they visit as tourists,” Kamiya said during a campaign speech, “but if you take in more and more foreigners, saying they’re cheap labour, then Japanese people’s wages won’t rise.”
Despite these views, the party insists it is not “exclusionary,” and does not advocate deporting foreign residents. Still, disinformation about immigrants—such as unfounded claims that foreign residents leave billions in unpaid medical bills—has spread widely on social media platforms, raising concerns among civil rights organizations and fact-checkers.
Digital Disinformation & Foreign Influence
Russia’s Shadow Looms Over the Narrative
Political analysts and researchers have warned that Russian bots and AI-generated content are playing a role in amplifying Sanseito’s message. A widely cited blog post by Ichiro Yamamoto of the Japan Institute of Law and Information Systems accused foreign actors of engaging in “large-scale information manipulation.”
Kamiya’s comments on Russia have only added fuel to the fire. While he condemned Moscow’s 2022 invasion of Ukraine, he also blamed “forces in the United States” for provoking it. He was forced to deny allegations of Russian support after a Sanseito candidate appeared on Russian state media.
Whether these ties are real or merely rhetorical, they’ve become part of Sanseito’s public narrative—one that blends nationalism with conspiratorial distrust of international institutions.
A Party for the Disenfranchised
Precarious Workers and Middle-Class Grievances
Much like Trump’s base in the U.S., Sanseito has tapped into economic anxiety, job insecurity, and resentment among Japan’s working and lower-middle classes. At a recent rally outside Tokyo’s Shinagawa Station, a 44-year-old IT worker summed up the party’s appeal:
“They put into words what I had been thinking about but couldn’t express for years,” she said. “When foreigners go to university, the government gives them subsidies. When we went, we had to take on huge debts.”
This emotional resonance has proven politically potent—even if the facts behind the grievances are debatable or outright false.
LDP Responds: Crackdown and Concessions
Mainstream Politics Shift Rightward
In response to Sanseito’s rise, Prime Minister Shigeru Ishiba’s ruling Liberal Democratic Party (LDP) has sharpened its stance on immigration. The LDP recently vowed to achieve “zero illegal foreign nationals” and pledged to tighten immigration enforcement systems.
While Ishiba’s coalition lost its upper house majority in Sunday’s vote, the LDP still commands significant influence. Yet the political center of gravity is shifting. Mainstream parties now find themselves echoing Sanseito’s rhetoric—or risk losing disenchanted voters to the new populist right.
Civil Society Pushback: Xenophobia Warning
NGOs and Academics Sound the Alarm
Eight prominent NGOs issued a joint statement, backed by more than 1,000 advocacy groups, denouncing what they see as a rise in xenophobia and racial scapegoating.
“The argument that ‘foreigners are prioritised’ is totally unfounded demagoguery,” the statement read, urging political leaders to avoid fanning public fear for electoral gain.
Hidehiro Yamamoto, professor of sociology and politics at the University of Tsukuba, noted that populism had not flourished in Japan previously because the LDP served as a “catch-all” party that appealed across urban, rural, and economic divides.
Now, with that coalition fragmenting, the door is open for new political movements to fill the void.
Will Sanseito Last?
Momentum vs. Staying Power
Japan has seen new parties rise and fall before. Movements built on short-term anger and identity politics often struggle to maintain relevance once in power. Even Yamamoto is skeptical of Sanseito’s long-term viability.
“You can’t continue gaining support only with a temporary mood among the public,” he said. “Real staying power requires policy execution and leadership beyond grievance.”
Yet in the short term, Sanseito has redefined Japan’s political conversation. What was once fringe is now mainstream. Populism, nationalism, and anti-globalist messaging are no longer taboo.
Whether this shift is fleeting or foundational will depend on what Sanseito does next—and how the establishment responds.

The emergence of Sanseito is more than an electoral blip. It’s the Japanese manifestation of a larger global transformation—one where economic insecurity, cultural anxiety, and distrust in elites fuel a potent form of nationalism.
As Japan wrestles with an aging population, a sluggish economy, and shifting geopolitical alliances, populist voices are no longer confined to the sidelines. They’re in the room—loud, influential, and growing.
