New Japanese Prime Minister Fumio Kishida dissolved the lower house of parliament Thursday with national elections set for Oct. 31.

Kishida said he is seeking the public’s mandate for his policies after being elected prime minister by parliament only 10 days ago to replace Yoshihide Suga.

Tadamori Oshima, the speaker of the more powerful lower chamber, announced the dissolution at a plenary session.

At the announcement, all 465 lower house lawmakers stood up, shouted "banzai" three times and left. They've now lost their seats and official campaigning for a new lower house begins Tuesday.

The last lower house election was held in 2017 under former Prime Minister Shinzo Abe.

His successor, Suga, lasted just a year as prime minister and his government's support was battered by his perceived high-handed approach in dealing with the coronavirus and insistence on holding the Tokyo Olympics despite rising cases that angered the public.

Kishida, tasked with rallying support for the ruling party, has promised to pursue politics of "trust and empathy."

He said in his first policy speech last Friday promised to strengthen the country’s response to the coronavirus pandemic in case of another resurgence and revive its battered economy while bolstering defenses against threats from China and North Korea.
