TOKYO -- Japan's ruling coalition of Liberal Democratic Party (LDP) and its partner Japan Innovation Party is expected to secure a majority of seats in the House of Representatives in Sunday's general election, public broadcaster NHK said, citing its exit poll.

Based on exit polls and other analyses, the ruling bloc is projected to win between 302 and 366 seats, meeting its target of securing a majority of 233 seats, NHK said.

For the LDP alone, the party is expected to win its single-party majority in the lower chamber, NHK said.

On the election day, NHK conducted an exit poll at over 4,000 polling stations nationwide, gathering responses from approximately 340,000 voters out of 571,000 surveyed -- a 59.7-percent response rate.
