The comments, less than 200 days before the postponed Games start in July, come with greater Tokyo under a state of emergency over a spike in coronavirus cases and with countries around the world battling outbreaks, AFP reported.
In a New Year's address to staff, Tokyo 2020 CEO Toshiro Muto put a positive spin on a Kyodo News poll published Sunday showing 45 percent want the 2020 Games delayed again, with 35 percent favoring outright cancelation.
"The number of people calling for it to be canceled has only risen by about five percent," Muto said.
"The number of people calling for it to be postponed has risen a lot, but that means those people still want it to be held," he added.
"Of course, for it to be held, we have to guarantee that we hold a safe Games with anti-virus measures. If you think of it in those terms, I firmly believe people will get more and more behind it."
Muto also dismissed as "fake news" a Japanese media report claiming the International Olympic Committee (IOC) and Tokyo 2020 organizers would debate the fate of the Games in February.
"When these types of reports surface, some people might feel anxious about them," said Muto.
"I want to say that we are not thinking that way at all, and that these reports are wrong."
British rowing great Matthew Pinsent on Monday called for the Games to be canceled and Tokyo to host the event in 2024 instead.
The four-time Olympic gold medalist tweeted that it would be "ludicrous" to host an event with thousands of people flying in unvaccinated.
Pinsent called for Tokyo to host the Games in 2024, with Paris taking over in 2028 and Los Angeles moving back to 2032.
Japan's government is expected to expand the state of emergency soon to several additional regions, and it has already lowered spectator caps at sports events in greater Tokyo to 5,000 people or 50 percent capacity, whichever is less.
And on Tuesday, rugby chiefs scrapped two games set for this weekend's domestic Top League season-opener after 46 people from four teams tested positive.
Tokyo 2020 organizers have drawn up a raft of anti-virus guidelines that they say will allow the Games to go ahead without a vaccine, and Muto said he was confident they will deliver after coming through the trials of last year.
"I think this is an amazing organization," said Muto. "There had never been a postponement before in history, and that one word 'postponement' can't sum up the amount of work that needed to be done.
"We still have a lot to do but we have overcome a lot and that gives us a lot of confidence as an organizing committee."
Japan is not expected to begin vaccination before late February.
Japanese media reported that Prime Minister Yoshihide Suga and billionaire philanthropist Bill Gates agreed Tuesday that vaccines must be distributed to developing countries to ensure the safety of the Games.
