General elections were held in Japan on November 9, 2003. Incumbent Prime Minister Junichiro Koizumi and the Liberal Democratic Party won the most seats in the House of Representatives but failed to secure a majority. The main opposition Democratic Party made considerable gains, winning 177 of the 480 seats in the House of Representatives, its largest share ever. Other traditional parties like the Communist Party and the Social Democratic Party lost substantial numbers of seats, marking the start of a newly consolidated two-party system in Japanese politics, which would end in 2012 with the emergence of the Japan Restoration Party.
