In a surprising turn during Japan’s 27th House of Councillors election held on July 20, the right-wing populist party Sanseitō made a major leap in political influence. Running under the slogan “Japan First” (日本人ファースト), the party defied expectations and appeared poised to win between 10 and 22 seats, according to NHK’s early projections. If they surpass the 11-seat threshold, they will gain the ability to submit legislation independently within the Upper House.

This development has sparked debates across the political spectrum. Sanseitō, led by the outspoken Kentaro Kamiya (神谷宗幣), has been widely recognized for its firm stance against globalism, mass vaccination, and what it describes as an overly submissive posture to international institutions.

A Surge Fueled by Dissent

Sanseitō’s rise is not simply about nationalism — it’s also a protest vote. The party has capitalized on widespread dissatisfaction with Japan’s COVID-19 policies, especially vaccine mandates and perceived government overreach. Many of its core supporters believe their concerns were ignored by mainstream media and the political elite. By tapping into online forums, YouTube, and alternative media channels, Sanseitō successfully mobilized a previously silent segment of the population.

In a television appearance on the night of the election, Kamiya stated,

“We have received more support than expected. Our mission is to be an antithesis to globalism, to restore Japan’s strength through tax cuts and active fiscal policy, and to make the country one where citizens can live without fear.”

Controversy Around “Japan First”

The party’s campaign slogan, “Japan First,” drew sharp criticism, with some accusing it of promoting xenophobia. In response, Kamiya argued that the phrase was misunderstood and unfairly labeled as discriminatory. He claimed it simply reflected a desire to prioritize domestic citizens’ well-being, not to exclude or target foreigners.

Still, the line between nationalism and exclusion remains blurry. Critics fear that such rhetoric may embolden anti-immigrant sentiments and deepen divisions within Japanese society, especially at a time when the country is grappling with demographic challenges and labor shortages.

What Lies Ahead?

If Sanseitō secures more than 11 seats, it will have the power to propose legislation — a major step up from its previous position. But legislative power comes with scrutiny. Key areas to watch include:

  • Anti-Vaccine and Health Policy Proposals: The party has consistently criticized COVID-19 vaccination campaigns and pharmaceutical companies. With more seats, it may push for investigations or laws to limit government health mandates.
  • Education and Media Reform: Sanseitō frequently claims that Japanese schools and media are “controlled by globalist interests.” Expect proposals to “restore traditional values” and reduce foreign influence in public education and broadcasting.
  • Fiscal Policy and Tax Reform: True to Kamiya’s words, the party is likely to demand aggressive tax cuts and large-scale fiscal stimulus — a platform appealing to small business owners and rural voters.
  • Foreign Policy and Immigration: While they deny xenophobia, their immigration stance remains conservative. Future proposals may focus on limiting foreign labor and strengthening cultural preservation.

Independent Analysis 🧠

Sanseitō’s momentum is part of a global trend: nationalist, anti-establishment parties gaining traction as voters grow disillusioned with conventional politics. The success of such parties often begins with cultural or health issues (e.g., anti-vaccine sentiment) but gradually expands to broader populist platforms.

However, translating electoral wins into tangible policy change is another matter. Japan’s political system, particularly the bicameral legislature and entrenched bureaucracy, may slow or dilute Sanseitō’s proposals. Furthermore, as media scrutiny increases, the party will need to moderate its messaging or risk political isolation.

Still, their presence alone will shift the Overton window — forcing mainstream parties to address issues they once avoided.

Conclusion

Sanseitō’s electoral surge reflects a changing mood in Japan — one where traditional values, economic frustration, and skepticism of global influence converge. Whether this party will become a fleeting protest vote or a lasting political force depends on its ability to evolve beyond slogans and deliver viable policy solutions.

One thing is clear: Japanese politics just got a lot more unpredictable.
