Despite the Liberal Democratic Party's landslide victory Sunday, Prime Minister Junichiro Koizumi reiterated his resolve to step down when his term as LDP president expires next September.

With all ballots counted, the LDP won 296 seats in the 480-seat House of Representatives, 84 more than it had going into the race. New Komeito, its coalition partner, lost three seats to finish with 31.

The LDP's gains came mostly at the expense of the Democratic Party of Japan, which saw its seats in the chamber plummet to 113 from 177. The crushing defeat has prompted the party to seek new leadership.
