Domestic fans will be allowed to attend events when the Tokyo Olympic Games open on July 23, the organizing committee and the International Olympic Committee (IOC) announced on Monday.

Organizers said venues could be filled to 50 percent capacity - up to a maximum of 10,000 fans. The decision came after an online conference involving the so-called "five parties"; the local organizers, the IOC, the International Paralympic Committee, the Japanese government and the government of metropolitan Tokyo.

Organizing committee president Seiko Hashimoto warned that, while officials hoped to be able to fill venues to 50 percent capacity, the coronavirus pandemic could force a change in plans.
