Democratic Party of Japan
The was a centrist to centre-left liberal or social-liberal political party in Japan from 1998 to 2016. The party's origins lie in the previous Democratic Party of Japan, which was founded in September 1996 by politicians of the centre-right and centre-left with roots in the Liberal Democratic Party and Japan Socialist Party. In April 1998, the previous DPJ merged with splinters of the New Frontier Party to create a new party which retained the DPJ name. In 2003, the party was joined by the Liberal Party of Ichirō Ozawa.

The DPJ was ousted from government by the LDP in the 2012 general election. It retained 57 seats in the lower house, and still had 88 seats in the upper house. During its time in office, the DPJ was beset by internal conflicts and struggled to implement many of its proposed policies, an outcome described by political scientists Phillip Lipscy and Ethan Scheiner as the "paradox of political change without policy
