The president of the Tokyo 2020 organizing committee does not rule out canceling the Olympic Games.
Toshiro Muto said he would keep an eye on the number of infections and hold “discussions” if necessary.
More than 70 people associated with the Games tested positive ahead of Friday’s opening ceremony.
His comments came on the same day, International Olympic Committee (IOC) President Thomas Bach said the cancellation was “never an option”.
Earlier this month, Japan announced that the Games will be held in empty stadiums – despite growing concern over the Covid situation.
“We will continue discussions if there is a spike in cases,” Muto said when asked at a press conference if the Games could be canceled even at this late stage.
“At this point, coronavirus cases may go up or down, so we’ll think about what to do when the situation arises. “
Although the Games don’t officially begin until Friday, the athletic action kicked off with the women’s softball and soccer competitions starting on Wednesday.
Earlier this week, two South African footballers staying in the Athletes’ Village tested positive for the coronavirus. A Czech beach volleyball player then tested positive for the virus.
A total of 71 people accredited for the Tokyo Olympics, including those accredited for the Games, have now tested positive for the virus.
The 2020 Olympics and Paralympics have been postponed for a year due to the coronavirus pandemic.
This is the first delay in the 124-year modern history of the Games.
The opening ceremony for the Olympics is scheduled to take place on July 23, although the first event of the Games – a softball match between Japan and Australia – took place on Wednesday.
The Olympics will end on August 8, with the Paralympic Games scheduled to start on August 24 and end on September 5.
But there has been public anger over the restrictions on coronaviruses.
The Japanese are also concerned about the influx of tens of thousands of people associated with the event and the impact they could have on infection rates.
The host city of Tokyo is facing a new wave of infections, with 1,387 cases recorded on Tuesday.
Japan is currently under a state of emergency that will be in effect until August 22.
Organizers “are 100% focused on making the Games a success,” a Tokyo 2020 spokesperson said after Mr Muto’s comments on Tuesday.
