Crowds at this summer’s Olympic Games in Tokyo have been capped at 50 per cent of a venue’s capacity, up to a maximum of 10,000.

Spectators will be asked to refrain from shouting or even talking loudly, and to travel directly to the venue and return home immediately afterwards. However, they are unlikely to be asked to prove they are negative for Covid-19, or fully vaccinated.

The president and chief executive of the Tokyo 2020 organising committee faced the media on Monday to provide details on the spectator plan, which comes after Japan’s top coronavirus adviser told them on Friday that the best way to limit the risk of infections was to hold the Games behind closed doors.

Proof of a negative Covid test or full vaccination are unlikely to be required to gain entry.

“We are looking into many different perspectives but requiring spectators to bring proof of negativity would be problematic,” he said.

“At this point in time we are not expecting them to bring any such certificate.”

Details of ticketing arrangements following Monday’s decision will be outlined on Wednesday, organisers said.

A decision had been taken to bar overseas spectators in April.
