Led by Yoshimi Watanabe, who split from the Liberal Democratic Party (LDP), the party was founded on August 8, 2009 after then-Prime Minister Taro Aso dissolved the lower house. One concept behind the party was to make the government more democratic, and to eliminate control of the government by non-elected members established in the bureaucracy. In this respect, Watanabe has repeatedly stated that his position is compatible with the Democratic Party of Japan.
Following an announcement by Prime Minister Shinzō Abe for an election to be held in December 2014, the party's 20 members voted on November 19, 2014 to disband on November 28, 2014. Falling support and disagreement over whether to side with the ruling coalition in the upcoming election were identified as reasons for the split.
