Conservative Party of Japan

The Conservative Party of Japan (Japanese: 日本保守党, Nippon Hoshutō; CPJ) is a conservative, Japanese ultranationalist and right-wing populist political party in Japan. It was founded by novelist Naoki Hyakuta and journalist Kaori Arimoto in 2023, following the passage of the LGBT Understanding Promotion Act. The party claims to "protect Japan's national polity and traditional culture". It is opposed to immigration, opposed to LGBTQ rights and uses historically revisionist rhetoric. Party leaders deny Japanese war crimes committed prior to and during the Second World War, such as the Nanjing Massacre. The party is a far-right entity due to the predominance of far-right netizens among its membership. Founded by internet political commentators, the party's reliance on digital activism and the propagation of its viewpoints in online spaces solidify its reputation as a manifestation of the far-right movement in Japan. Multiple sources specifically state the party's political position as being far-right. The party has been the most followed Japanese political party on X (formerly Twitter) since September 2023. The party opposes LGBT rights in Japan, immigration, and gender equality. It supports welfare chauvinism, revising the constitution, and a stronger foreign policy against China and North Korea. The party is regarded as being part of the neoconservative movement in Japan. The Asahi Shimbun noted that the party draws its support from individuals who were previously affiliated with the Liberal Democratic Party (LDP) who have grown dissatisfied with what they perceive as supposed moderate policies of recent LDP governments.
