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 change".
It is not to be confused with the now-defunct Japan Democratic Party that merged with the Liberal Party in 1955 to form the Liberal Democratic Party.
The previous parties ranged in ideology from conservative to social-democratic.
The new party began with ninety-three members of the House of Representatives and thirty-eight members of the House of Councilors.
Following the 2009 election, the DPJ became the ruling party in the House of Representatives, defeating the long-dominant Liberal Democratic Party (LDP) and gaining the largest number of seats in both the House of Representatives and the House of Councillors.
The 2005 snap parliamentary elections called by Junichiro Koizumi in response to the rejection of his Postal privatization bills saw a major setback to the DPJ's plans of obtaining a majority in the Diet.
The DPJ leadership, particularly Okada, had staked their reputation on winning the election and driving the LDP from power.
He was replaced by Seiji Maehara in September 2005.
However, Maehara's term as party leader lasted barely half a year.
