Japan, a parliamentary democracy, has been dominated by a single party governing by itself or in coalition with others for nearly all of the last half century. But falling popularity of the Liberal Democratic Party (LDP), an economy in decline, and growing public dissatisfaction with politics, pose a historic opportunity for the opposition in the August 2009 parliamentary election. The main opposition party, the Democratic Party of Japan (DPJ), gained a majority in the upper house of the Diet (parliament) in 2007 and since has emerged as a viable alternative to the LDP.
