Sanseitō (Japanese: 参政党, lit.'Political Participation Party'; self-rendered as Party of Do it Yourself!! in English) is a right-wing populist political party in Japan. The party was founded in 2020 and won a seat in the 2022 House of Councillors election, also becoming an official political party by winning more than 2% of the vote in the election.

The party promotes COVID-19 misinformation and anti-vaccine views. The party's president, Manabu Matsuda, has called COVID-19 vaccines a "murder weapon". Sanseitō gained international media attention during the 2022 House of Councillors election due to the party's Secretary General, Sohei Kamiya's antisemitic rhetoric during public appearances and campaign rallies. Observers noted that Sanseitō differ from usual far right political parties in Japan, as most of its supporters are affluent, previously politically apathetic, who get attracted by the party through topics like organic food culture and spirituality.
