Genzei Nippon

Genzei Nippon (減税日本; lit. 'Tax Reduction Japan') is a regional political party based in Nagoya, Japan and led by the former mayor of Nagoya, Takashi Kawamura. The party was formed by Kawamura in April 2010. After briefly holding several seats in the national legislature, the party merged at the national level with the Tomorrow Party of Japan in November 2012 before that party's dissolution in May 2013. Genzei Nippon remained a separate party at the regional level and has been active within Aichi Prefecture. As well as Kawamura, the party has thirteen members serving on the Nagoya city council and three members serving on the Aichi Prefectural Assembly.

In October 2023, it was announced that the party would be affiliated on the national level with Naoki Hyakuta's far-right Conservative Party of Japan, but the relationship was severed in September 2025 after a feud between Kawamura and Hyakuta.
