What Is Sanseito?

Understanding Japan’s New Political Party

Founder of Sanseito – Sohei Kamiya

Japan’s political landscape is usually dominated by long-standing parties like the Liberal Democratic Party (LDP) or the Constitutional Democratic Party (CDP). But in recent years, a new name has started to appear more frequently: Sanseito (参政党).

Founded in 2020, Sanseito has gained attention, especially among younger voters and those disillusioned with traditional politics. But what exactly is this party about? What do they believe in? And why are people talking about it?

Let’s take a closer look.


🏛️ What Does “Sanseito” Mean?

The word 参政党 (Sanseito) literally means “Party for Participation in Politics”. The name reflects the party’s mission: to encourage ordinary citizens to take part in political decision-making, rather than leaving it all to long-time politicians and bureaucrats.


📜 A Brief History

Sanseito was officially formed in March 2020, and it made headlines during the 2022 House of Councillors election, when it won its first seat in the national legislature. For a brand-new party with limited funding and media coverage, this was a significant achievement.

Much of its support has come from grassroots movements, YouTube, and social media platforms, reaching people who feel ignored by the mainstream.


🧭 What Does Sanseito Stand For?

Sanseito’s platform is a mix of conservative values, populism, and nationalist themes, but also focuses heavily on education reform, food safety, and personal responsibility.

Here are some of their key issues:

  • 🧠 Education Reform: Sanseito wants to shift Japanese education toward more traditional and moral teachings. They believe the current system neglects spiritual and cultural values.
  • 🍚 Food and Health: The party strongly promotes natural farming, organic food, and skepticism toward GMO products and vaccines. They often speak about the importance of protecting health from modern chemicals and pharmaceutical influence.
  • 🇯🇵 National Sovereignty: Sanseito emphasizes protecting Japanese identity, language, and traditions, and they’re skeptical of globalism and foreign influence on domestic policy.
  • 🧍‍♂️ Citizen Participation: They push for more political involvement from the average Japanese person and offer platforms for people with no political background to run for office.

📢 Why Is Sanseito Controversial?

Sanseito has sparked debate for several reasons:

  • Some of their health claims (especially anti-vaccine or anti-pharma stances) have been criticized by medical experts.
  • Their nationalistic tone appeals to some but concerns others who fear it promotes xenophobia or historical revisionism.
  • They have been called “populist” for their style of messaging—directly appealing to people’s frustrations with the government and mainstream media.

Whether you support them or not, Sanseito is tapping into growing dissatisfaction with the status quo.


📈 Who Supports Sanseito?

Their support base is diverse:

  • Middle-aged and older citizens who feel that traditional values have been lost
  • Parents who are concerned about Japan’s education and food safety
  • Younger people seeking a new political voice outside of the “old guard”
  • Some people who are influenced by YouTube channels, influencers, or alternative media that feature Sanseito candidates

In short, they’re attracting people who are not necessarily “left” or “right”, but feel disconnected from mainstream politics.


🗳️ What’s Next for Sanseito?

With their recent success in gaining seats and building an active supporter base, Sanseito is expected to play a larger role in local and national elections going forward. They may not have enough power to shift national policy yet, but they’re changing the way political conversations happen, especially online.


💬 Final Thoughts

Sanseito is one of the most interesting political developments in recent Japanese history. Whether you see them as a hopeful grassroots movement or a risky fringe party, they’re clearly striking a chord with many voters.

In a country where politics can feel distant and impersonal, Sanseito is trying to bring it closer to the people. The question is—will they continue to grow, or will they fade like other small parties before them?

Either way, they’re a party worth watching.
