TOKYO, Sept. 11 (Xinhuanet) -- Japan's ruling Liberal Democratic Party (LDP) would attain a majority in the lower house election held Sunday, according to the exit polls by major broadcasters.

    The LDP is expected to gain 285 to 325 seats in the 480-seat lower house, the public broadcaster NHK said. The major opposition Democratic Party of Japan (DPJ) would got 84 to 127 seats, and the LDP's ruling partner -- the New Komeito party -- would grab 28 to 36 seats, NHK said.

    The NTV's exit poll showed that the LDP would gain 309 seats, the DPJ, 104 seats, and the New Komeito, 33 seats.

    Polls from other major TV stations also gave showed certainty that the ruling party, or the ruling bloc at least, would be certain to remain in power.

    So far, the LDP has secured 142 seats against the 44 seats garnered by the DPJ, according to NHK. Plus the 17 seats gained by the New Komeito party, the ruling bloc has achieved 159 seats.

    Prime Minister Junichiro Koizumi has said he would resign as LDP leader if the ruling coalition fails to gain a majority, so has DPJ President Katsuya Okada.

    Shinzo Abe, acting secretary general of the LDP, said live on a NHK program, that the situation was better than expected and hoped the LDP would get a majority.

    Abe said if the ruling bloc could stay in power, they would re-submit the postal reform bills at a special parliament session to be convened soon after the election, and get them passed.

    Abe noted that even if the LDP gains a majority alone, it will still form a government in alliance with the New Komeito party.

    If the LDP attains a majority, it will be the first time for the party to cross the threshold in 15 years and also for the first time under the single-seat constituency system introduced in 1994. Enditem
