Opposition party leaders lashed out at Prime Minister Yoshihide Suga on Friday after he abruptly announced his intention to step down when Japan is battling to stem a surge in coronavirus cases.

ID-19 cases has been requiring a swift response and that no time should be wasted.

The Liberal Democratic Party, headed by Suga, "is not qualified to run the government," Edano told reporters.

Suga said he will not run in the LDP presidential election, scheduled for Sept. 29, backpedaling on his earlier remarks that he would seek re-election.

The announcement set the stage for a new face to become LDP president and thus the country's prime minister. Suga's term as LDP head expires on Sept. 30.

Akira Koike, second-in-command of the Japanese Communist Party, said, "It shows that the LDP-Komeito government is at an impasse," in reference to the ruling party's coalition partner.

Suga became prime minister a year ago following his predecessor Shinzo Abe's abrupt departure for health reasons.

He has seen public support for his Cabinet plummet in opinion polls that highlighted public dissatisfaction with the government's response to the pandemic as the highly contagious Delta variant of the coronavirus is spreading.

"It's an emergency that the leader responsible for the coronavirus response has announced his intention to resign at a time when (many parts of Japan) are under a state of emergency," said Yuichiro Tamaki, who heads the Democratic Party for the People.

Suga's departure means "he is effectively taking responsibility for the failed response (to the pandemic)," Tamaki said.

The LDP this week rejected calls by the opposition bloc to convene an extraordinary Diet session to deliberate on steps to combat COVID-19 before the ruling party's presidential election.
