It had 2 out of the 475 seats in the House of Representatives, and 3 in the 242-member House of Councillors prior to merging. Formed as the People's Life Party (生活の党) in December 2012, it changed its name to People's Life Party & Taro Yamamoto and Friends (生活の党と山本太郎となかまたち) in December 2014. The party adopted the name Liberal Party in October 2016 in preparation for an expected general election in early 2017.

The Democratic Party for the People , abbreviated to DPP or DPFP, is a centre to centre-right, conservative political party in Japan. The party was formed on 7 May 2018 from the merger of the Democratic Party and Kibō no Tō. In September 2020, the majority of the party reached an agreement to merge with the Constitutional Democratic Party of Japan and the original party was officially dissolved on 11 September 2020. However, 14 DPP members refused to merge, including party leader Yuichiro Tamaki, and instead formed a new party retaining the DPP name and branding.
