Medical staff working at Games venues will undergo daily coronavirus tests, according to Olympic minister Tamayo Marukawa.
The tests will be conducted on "people who are likely to be in close proximity with athletes, within 1 meter for more than 15 minutes," Marukawa told reporters on Tuesday.
Some media personnel, volunteer interpreters, and drivers are also expected to be tested to prevent the spread of infections.
The movements of athletes and competition officials will be restricted during the Games to create an isolated "bubble" from the outside world, with participants moving mainly between the athletes' village and competition venues.
"One of the criteria [for the daily testing] will be whether people enter the bubble," Marukawa said.
Marukawa also said Tuesday that supercomputers and artificial intelligence technology will be used to verify the flow of people around the venues for the Games as part of efforts to prevent the spread of the coronavirus.
Marukawa said the central government plans to work with the Tokyo metropolitan government on the project.
"I want to integrate science in our response to the concerns of the public [regarding the Games]," she said.
