TOKYO - Japan's main opposition party, the Liberal Democratic Party (LDP), is expected to hold more than half of seats in the House of Representatives, the latest polls showed.

The LDP, headed by former Prime Minister Shinzo Abe, and its ally the New Komeito Party could totally win about 300 seats in the 480-seat lower house, according to a Kyodo's two-day survey, which randomly selected more than 120,000 eligible voters across the country.

The Asahi Shimbun and the Yomiuri Shimbun, two major Japanese newspapers, also said respectively in their polls that the LDP would secure more than 240 seats in the general election.

The situation for the ruling Democratic Party of Japan (DPJ), led by Prime Minister Yoshihiko Noda, is not optimistic. The three polls suggested that the DPJ would loss half of its seats held in the lower house and probably secure no more than 70 seats in the election.

The third forces that comprised the Japan Restoration Party, the Tomorrow Party of Japan and Your Party are struggling to increase their supports.

However, Kyodo's survey also showed more than 40 percent respondents have not yet decided on who and which party they will vote for in the single-seat districts and the proportional representation regional blocks.
