In Japan, the health situation linked to the coronavirus is worrying.

And this is reflected in the organization of the Olympic Games, which start next week.

Surveillance, testing and confinement ... Athletes live their last days of preparation in a special atmosphere. 

With a week before the start of the Tokyo Olympics, the atmosphere is not celebrating.

With the resurgence of Covid-19, the state of health emergency was restored throughout the duration of the event in the Japanese capital, where there are more than 1,000 positive cases per day.

A first since last January.

Athletes and members of delegations are also affected despite the strict measures. 

"We are watched by everyone"

On Thursday, an athlete tested positive when he arrived on Japanese soil.

No information on his identity or his nationality but one thing is certain: this is not an isolated case.

A member of the staff of the Russian rugby sevens team even had to be hospitalized.

The players were placed in solitary confinement.

However, the measures decreed by the Japanese government are drastic.

"We are tested every morning," says Laurent Tillie, the coach of the France volleyball team who is preparing for the Games with his players on the island of Okinawa.

For them, it is forbidden to leave the hotel: journeys are limited to between the fourth floor they occupy and the gymnasium.

And no need to monitor athletes by GPS.

"We are watched by everyone," says Laurent Tillie.

Over 85% of athletes are vaccinated

Despite the state of emergency declared in Tokyo earlier this week, the International Olympic Committee (IOC) is confident: more than 85% of athletes participating in the Games will be vaccinated.

The event will also take place without an audience as more than 4.5 million tickets had been sold before the pandemic.

Some athletes have even been discouraged by the coronavirus pandemic.

Novak Djokovic announced Thursday his participation next week in the Tokyo Olympics but the Serbian tennis player had, for a long time, left in doubt about his coming.

Others have decided to skip the line, like Roger Federer.

Rafael Nadal or Dominic Thiem.
