^ A: The party is commonly seen in Japanese and Western media as centre-right. The party is sometimes described as far-right by South Korean outlets. The party has also been described as right-wing populist.

The Japan Innovation Party (日本維新の会, Nippon Ishin no Kai; Japan Restoration Association) is a political party in Japan based in Osaka, variously described as conservative, centre-right, right-wing, and right-wing populist.

The party was founded in October 2015, as Initiatives from Osaka, from a split in the old Japan Innovation Party. It ended up becoming the third-largest opposition party in the National Diet following the 2016 House of Councillors election. In the 2017 general election, the party won 11 seats, down from the 14 it held previously. In the 2019 House of Councillors election, it won 4 new seats. In the 2021 general election, the party gained 30 seats, becoming the third-largest party in the chamber, winning nearly all seats in Osaka while also expanding its representation outside the prefecture. In the 2024 general election, it lost several of its seats but kept its dominance in Osaka. In 2025, the party formed a governing coalition together with the Liberal Democratic Party (LDP) following the collapse of the 26-year-long LDP–Komeito coalition.

The Japan Innovation Party advocates decentralization, federalism (Dōshūsei), and limited government policies. It argues to remove defense spending limits, and stands with the LDP on revising the constitution. The party also supports socially liberal policies such as expanded LGBTQ protections and same-sex marriages, while also backing free high school education. The party has represented a form of right-wing populism that until 2025 opposed the LDP's entrenched control over Japanese politics and bureaucracy, known as the 1955 System.
