TOKYO (Kyodo) -- Japan's daily total of COVID-19 cases topped 9,000 for the first time on Wednesday, with a surge in infections in Tokyo casting a pall over the Olympics and putting pressure on the government of Prime Minister Yoshihide Suga to take stronger countermeasures.
The capital confirmed 3,177 COVID-19 cases, hitting a record for the second straight day and pushing up the nationwide tally to exceed the previous all-time high of 7,958 set Jan. 8, as hospitals come under increasing strain.
The surge in infections comes as the highly contagious Delta variant of the coronavirus spreads and people in Tokyo tire of restrictions under a state of emergency.
The record high was reported just a day after Tokyo logged 2,848 daily COVID-19 cases, exceeding the previous record of 2,520 cases on Jan. 7.
The virus has spread rapidly elsewhere, with the nationwide tally of daily infections that was below 2,000 in early July surpassing 4,000 one week ago, 5,000 on Thursday and 7,000 on Tuesday.
On Wednesday, the daily count for the entire country reached 9,583, while Tokyo's neighboring prefectures of Kanagawa, Saitama and Chiba also all reported record highs at 1,051, 870 and 577, respectively.
Japan's National Institute of Infectious Diseases has estimated that the Delta variant is now responsible for about 70% of infections in the metropolitan area.
Olympic organizers have pledged to implement adequate COVID-19 countermeasures for a "safe and secure" games, and stressed that the number of infections among athletes and others associated with the sporting extravaganza is very low.
Suga has denied the possibility of canceling the Olympics, which opened Friday without spectators at almost all venues, and said that "there is no worry" as people are expected to move around less.
But Takaji Wakita, head of the national institute, who also leads the health ministry's COVID-19 countermeasures advisory panel, warned at a press conference on Wednesday that "the spread of infections (over this one week in the country) is something never experienced before."
The government has placed Tokyo under a fourth state of emergency, which mostly relies on a cooperative public and does not entail a hard lockdown like some countries have imposed, from July 12 to Aug. 22.
Still, some restaurants and bars have ignored calls to stop serving alcohol and close early as the government has lagged in handing out "cooperation money" meant to help them cover lost revenue.
Many people, especially younger ones less likely to be vaccinated, have grown weary of the restrictions and begun going outside more.
"How young people behave is key," Tokyo Gov. Yuriko Koike told the press on Wednesday, advising them to get their shots.
"The medical system has already started becoming more strained," Shigeru Omi, Suga's top COVID-19 adviser, said in a parliamentary hearing, calling on the government to "send out a message that gets across the sense of crisis they should be feeling and take countermeasures fitting of the current infection situation."
The governors of three prefectures surrounding the capital -- Chiba, Kanagawa and Saitama -- will ask the central government, possibly Thursday, to be placed under the same state of emergency.
The government will "promptly consider such requests and make a decision," Chief Cabinet Secretary Katsunobu Kato said at a press conference Wednesday.
Suga also met with members of his Cabinet including health minister Norihisa Tamura to discuss the current situation.
As early as Friday, the government will convene a meeting to decide on putting the three prefectures under the emergency, an official said.
Suggesting there are not many options for the government, a senior official at the prime minister's office, said, "We have used almost all cards available by now."
Meanwhile, the Olympics organizing committee said Wednesday that 16 more people linked to the games, none of them athletes, have tested positive for COVID-19, bringing the total since the start of this month to 169.
It is the first time in four days that the organizers have reported no COVID-19 positive cases of Olympic athletes.
