The Liberal Democratic Party is likely to win a majority of the 480 seats in the House of Representatives in next Sunday's general election, according to a Kyodo News survey.
The opposition Democratic Party of Japan is expected to boost its presence in the Lower House, but the number of seats could come to about 160, far short of its aim of 200 or more.
The telephone survey, conducted Friday and Saturday, drew a response rate of 54 percent from 259,000 people contacted.
