Opinions seem to be equally mixed in Japan, where the Olympic flame arrived by plane from Greece on Friday.
"Cancelling the torch relay could have been a signal that you are siding with the people in the times of the pandemic", Hartung told dpa.
Opposition to holding the Games in July has risen sharply in the past 48 hours, with several major stakeholders such as U.S. Track and Field and UK Athletics along with several national Olympic committees, calling for a delay because of the pandemic.
Japan Prime Minister Shinzo Abe has said he wants to hold the Olympics in their "complete form" and "without reducing the scale, and with the spectators also able to enjoy the feeling" of the games, Bloomberg reported.
Since the global threat became clear in February, the International Olympic Committee refused to consider a change, hoping that the cushion of the mid-summer start might allow the spread of infection to dwindle before the Games.
Consultation with Japanese public authorities, global sports officials, broadcasters and sponsors will deal with "scenario planning" for the July 24-Aug. "Therefore it is not on our agenda", Bach wrote.
A growing number of Canadian athletes have already voiced their displeasure with Olympic leaders such as president Thomas Bach after regional Olympic officials on Wednesday rallied around the IOC and backed its stance on opening the Tokyo Games as scheduled.
This time it's all about saving the dream of Olympia for many athletes - by postponing the games to 2021 or 2022.
The Summer Olympics take place every four years in a host city, and it takes years of planning and preparation for the city and country to hold such a large-scale event.
International Olympic Committee president Thomas Bach has signaled his determination to press ahead with the Games in Tokyo from July 29 to August 9, telling the New York Times that postponement "would not be responsible now" as "we are four-and-a-half months away from the Games".
The double Olympic 1,500 metres champion said postponing Tokyo 2020 would put an end to the "real anguish" and "uncertainty" being felt by athletes due to the pandemic and its impact on their training and qualification for the Games.
This week, the Spanish and Dutch cycling federations joined their respective Olympic committees urging that the Games be rescheduled.
"The IOC is confident that it will have finalized these discussions within the next four weeks".
At this point, many global federations and national Olympic committees are continuing to support a wait-and-see approach for this summer.
Officials urging a rescheduling of the competition say that the worldwide health crisis not only creates an uneven playing field, but also puts athletes and other staffers under undue physical and mental stress.
"The aim is to clarify which of you might want to take part in the Olympic Games on the dates planned and who is in favour of another date".
"Japan has invested a lot of resources into the Olympics and they are adamant that the Games should go ahead, but that defies common sense and we can not support it because human lives come first", Serbian Olympic Committee president Vanja Udovicic said. Thousands of Olympic hopefuls have been left in limbo with many qualifying events around the world postponed or cancelled.
