According to the Kyodo news agency, the country expects some 30,000 athletes, coaches and team members to come to the Olympics and Paralympics. A further 60,000 people are other Olympics-related travelers accompanying the teams, and their number may be halved.
The measure is driven by pandemic precautions and uncertainty over the emergence of coronavirus mutations.
Rescheduled from 2020 to 2021 due to the pandemic, the Tokyo Olympics will run from 23 July 8 August. The country has already barred foreign spectators from the Games, with the decision on Japanese fans to be made in April.
