The International Olympic Committee (IOC) says it remains fully committed to Tokyo 2020, and is seeking to find a solution in a responsible way.
The IOC said there was no need "for any drastic decisions at this stage" in relation to Tokyo 2020, adding that preparation for the games is constantly changing due to the challenges thrown by the COVID-19 pandemic.
"The health and well-being of all those involved in the preparations for the Olympic Games Tokyo 2020 is our number-one concern. All measures are being taken to safeguard the safety and interests of athletes, coaches and support teams," IOC President Thomas Bach said.
"We are an Olympic community; we support one another in good times and in difficult times. This Olympic solidarity defines us as a community."
The IOC communique noted that a task force was set up in mid-February, consisting of the IOC, the World Health Organisation, the Tokyo 2020 Organising Committee, the Japanese authorities and the Tokyo Metropolitan Government to keep a constant appraisal of the situation.
