A number of sporting events have moved after the outbreak which has killed more than 1,350 people and infected tens of thousands more in China.
But Tokyo 2020 president Yoshiro Mori said the Games would open as planned on July 24.
Head of the IOC's coordination commission John Coates said advice the International Olympic Committee had received "externally" from the World Health Organization was that "there is no case for any contingency plans of canceling the Games or moving the Games".
A spokesperson said: "We are of course aware of the cancellations and postponements of high-level global sports events in China and continue to monitor the situation closely".
The spread of the coronavirus has forced the cancellation or rescheduling of a host of worldwide sporting events, including a number of 2020 Olympic qualifying competitions for sports including badminton and boxing, both of which were set to take place in China.
The spreading outbreak, whose epicentre is the Chinese city of Wuhan, has prompted the cancellation of some global sporting events, as well as 2020 Games qualifying competitions for boxing and badminton that were due to take place in China.
There have been more than 60,000 confirmed coronavirus cases in mainland China and almost 450 in 24 other countries and territories, including 33 in Japan and another 218 on a cruise ship quarantined at a Japanese port.
Action in the discipline is set to conclude at 11:10am, marginally outside of the 11am cut-off point decided by the Organising Committee and the International Olympic Committee (IOC).
Formula One's Shanghai Grand Prix has been postponed from mid-April, with the inaugural Vietnamese Grand Prix also under threat as well as the Hong Kong Sevens.
Coates said that meetings over the past two days had "reinforced our confidence" that the Japanese government is properly addressing the virus, adding that any Chinese athletes or fans coming from China, particularly affected areas, would have to adhere to Japanese government protocols.
