Hours after being sworn in by Parliament to be the 100th Prime Minister of Japan on Monday (Oct 4), Japan's new Prime Minister Fumio Kishida said he will call a general election on Oct 31.

Prior to it, the Diet will be dissolved after an extraordinary session on Oct 14 for the election, just a week before its four-year Lower House term expires on Oct 21.

Nomination Day will be on Oct 19. Mr Kishida, 64, spelt out the timeline at his first news conference since becoming Japan's 100th prime minister.

Fumio Kishida, leader of Japan's ruling Liberal Democratic Party (LDP), was elected on Monday as the country's new Prime Minister to succeed Yoshihide Suga.

As the ruling coalition led by the LDP controls both chambers, 64-year-old Kishida secured a majority of votes of both the House of Representatives and the House of Councillors during a special Parliament session called to elect a new Prime Minister, reports Xinhua news agency.

After naming his new Cabinet in the afternoon, Kishida will be formally inaugurated in a ceremony at the Imperial Palace and hold a press conference in the evening.

"This is the real starting point. I will go forth with a strong sense of determination, with a strong resolution," he said at the LDP's headquarters in Tokyo shortly before the session started.

Kishida's first major test as Prime Minister will be the general election. He is planning to hold the election on October 31, while campaigning for members of the House of Representatives is set to begin on October 19.

According to local media reports, he plans to hold the vote on November 7. On Monday morning, Suga's Cabinet resigned en masse, little more than a year after its formation, amid criticism over its lack of ability to curb Covid-19.
