The New Conservative Party (NCP) was the name of two now-defunct political parties in Japan with a common lineage.
The first incarnation of the party (保守党, Hoshutō, lit. 'Conservative Party') was founded on April 3, 2000 by 20 lower house and 6 upper house defectors from the Liberal Party. This party was dissolved briefly and then re-established (as 保守新党, Hoshu Shintō, lit. 'New Conservative Party') on December 25, 2002 in order to accommodate defectors from the Democratic Party of Japan.
The party eventually merged with the Liberal Democratic Party after the 2003 election.
