Athletes and their close contacts will have daily coronavirus tests at this summer's Tokyo Olympics

"In principle, athletes and all those in close proximity with athletes will be tested daily to minimize the risk of undetected positive cases," Tokyo 2020 said in a statement.

Both athletes "and all those in close proximity with athletes will be tested daily to minimize the risk of undetected positive cases that could transmit the virus," Olympic officials said.

Other rules for Olympic participants will include a ban on the use of public transport and avoiding restaurants.

Olympic organizers hope that bolstering the rules will help build support for the 2020 Games in Japan, where polls show most people back either a cancellation or further delay.

"We are ready with you to take all the necessary measures to minimize the risks to make the Japanese people feel safe," International Olympic Committee chief Thomas Bach said at the start of the talks.

"Our top priority is health and safety for everyone –- not only for the participants of the Olympic Games but, first and foremost, also of our gracious hosts, the Japanese people."

'People are anxious'

Japan has seen a comparatively small virus outbreak, with just over 10,000 deaths, but it is now battling what experts call a fourth wave of the virus.

A new state of emergency was imposed on Tokyo and three other areas on April 25, and the government's top medical advisor warned Wednesday that discussions should start soon on how the Games could be held if infections remain high by the summer.

"What's very important is the situation of the infections and how overwhelmed the medical system is," Shigeru Omi told parliament in response to a question from an opposition lawmaker.

"I think it is time to discuss the Olympics," he added, while stopping short of calling for either a postponement or cancellation.

Olympic officials insist the Games can still be held safely, Hashimoto last week saying that organizers are "not thinking about cancellation".

"There are so many people who are looking forward to the Games," she said on Wednesday.

"But, on the other hand, there are a lot of people who are anxious. That's the reality, and we need to look at both sides."

Olympic chiefs took the unprecedented decision to ban overseas fans in March, in a bid to reduce virus risks.
