Japanese authorities say only 10,000 Japanese fans will be permitted at venues during the Tokyo 2020 Olympics.
Overseas fans have already been banned from the Games.
Authorities say that capacity will be set at 10,000 spectators, provided it does not exceed 50 per cent of a venue’s capacity.
Other restrictions include that fans will not be allowed to shout or speak loudly during the games, and must wear face masks while in venues.
The Games are scheduled to begin on July 23, while the Paralympics follow a month later from August 24.
Spectator numbers for the Paralympics will be confirmed by July 16, according to a joint statement from the International Olympic Committee, International Paralympic Committee, Tokyo 2020 Organising Committee, Tokyo metropolitan government and government of Japan.
The parties said they will consider further restrictions should there be a rapid increase in COVID-19 infections and impact on Japan’s healthcare systems.
Prime Minister Yoshihide Suga last week encouraged the Japanese public to watch the Games on television, rather than attending events in person.
Emergency COVID-19 restrictions had been in place in Japan’s capital and other regions since late April amid a surge in infections.
A state of emergency in Tokyo was lifted on Sunday, five weeks before the start of the Olympics.
