Prime Minister Shinzo Abe's Liberal Democratic Party and Komeito, its junior partner in the ruling coalition, won the Lower House election by a landslide Sunday, claiming 325 seats in the powerful chamber.

In an election billed as a touchstone for the LDP's economic policies, the ruling bloc secured a two-thirds supermajority in the 475-seat House of Representatives, giving it the power to override the Upper House.

After focusing most of his campaign on the economy, Abe said in an interview on TV Asahi Sunday night that he would pursue his pet goal of amending the pacifist Constitution, a contentious issue he avoided but which promises to drastically change the nation's defense posture.
