Representatives from the Tokyo 2020 Olympic organising committee have said there were no doubts or objections from its partners, including the International Olympic Committee and sporting federations, about Japan hosting the rearranged Games this year.
Tokyo organisers are preparing for the Olympics, which are due to start on 23 July, against a backdrop of dwindling public support for the Games in Japan amidst the coronavirus pandemic.
The organising committee's president Yoshiro Mori spoke with IOC President Thomas Bach today and said he had received assurances from the German that Tokyo had the full backing of all Olympic stakeholders.
"No one from anywhere raised questions or objections (over the Olympics) and everyone wants to quickly make the Games successful," Mr Mori said, relaying his conversation with Bach.
Mr Mori also said Mr Bach had asked Tokyo officials for an update on Japan's vaccination roll-out.
Japan lags behind most other developed nations, with the first vaccinations not expected until late February.
Mr Bach has stressed the governing body was not in favour of athletes "jumping the queue" for vaccinations ahead of people under more threat from the virus, but some countries, including Australia and Israel, have started vaccinating athletes.
"President Bach expressed his hope that there will be progress with vaccinations in Japan and that as many people as possible, as quickly as possible, will be able to get the vaccine," Tokyo 2020 CEO Mr Muto said.
He also told reporters that organisers were running "each and every" simulation, including scenarios around foreign athletes entering and leaving Japan.
"We believe that we can hold the event without considering vaccination as a pre-requisite," he said.

A report in The Times claimed the Japanese government has "privately concluded" that the Olympics and Paralympics will have to be called off due to rising Covid-19 rates.
The IOC issued a statement in which it referenced the response of the Japanese government in describing the report as "categorically untrue".
It added: "The IOC is fully concentrated on and committed to the successful delivery of the Olympic and Paralympic Games Tokyo 2020 this year."
