Athletes at the coronavirus-postponed Tokyo Olympics will face regular testing, restrictions on mingling and potential punishment for non-compliance with health rules, organizers said Wednesday as they outlined plans for holding the Games.

After months of talks, officials issued a 54-page report outlining how they believe the Games can go ahead, even if the pandemic is not under control by the new start date of July 2021.

Quarantine requirements will be waived for overseas spectators, who will also be able to use public transport, but they will have to observe rules ranging from mask-wearing and a ban on cheering to keeping their ticket stubs to help contact-tracing.

Tokyo 2020 CEO Toshiro Muto acknowledged strict safety measures will make the games "different," but expressed hope they can still be held in a celebratory atmosphere.

"It will be simple rather than festive, but I hope it will be something moving that encourages people through the power of sport," he said.

Athletes will be screened on arrival in Japan and then undergo regular tests every four to five days during their stay at the Olympic Village.

An infection control center will also be set up to deal with positive cases, which organizers say they presume will occur.

However, officials have not yet announced how competition rules would be affected if an athlete contracted coronavirus during the Games.

All athletes must sign up to a code of conduct that includes avoiding speaking loudly, avoiding physical contact with others and wearing masks when not training or competing.

They will also be asked to leave Japan as soon as their events are over, rather than stay on in the country for sightseeing.
