Japanese Prime Minister Shinzo Abe said for the first time, on Monday, that the Tokyo Olympic Games may need to be postponed if the event cannot be held in its 'complete form' due to the coronavirus pandemic.
The International Olympic Committee (IOC) said on Sunday after an emergency meeting that it is stepping up its 'scenario planning' for the 2020 Games due to start on July 24, including a possible postponement.
Abe said that while cancelling the Games was not an option, a delay was now on the cards if that was the only way to hold the event in its complete form.
"If that becomes difficult, we may have no option but to consider postponing the Games," he told parliament.
He said he had conveyed his views to Tokyo Games chief Yoshiro Mori on Sunday evening, who then discussed the issue with IOC President Thomas Bach.
Under mounting pressure from athletes, federations and national committees to postpone the Games, the IOC did a partial U-turn on Sunday after long insisting, with Tokyo organisers, that the Games would go ahead as planned.
Tokyo 2020 organisers have started drafting alternative dates for the Olympics, sources have told Reuters.
More than 13,000 people have died globally since the coronavirus outbreak began in China late last year, with the epicentre now in Europe.
As of Sunday morning, Japan had 37 deaths and 1,055 coronavirus cases, excluding those from a cruise ship that was quarantined near Tokyo last month and returnees on chartered flights from China, a tally by public broadcaster NHK showed.
Abe said all travelers from the United States, including Japanese citizens, would be asked to go into quarantine for 14 days after their arrival in Japan.
In the United States nearly one in three residents has been ordered to stay at home to slow the spread of the flu-like virus as cases nationwide topped 32,000, with more than 415 dead, according to a Reuters tally.
Japan's foreign ministry has advised citizens to avoid non-essential and non-urgent travel to the United States.
