The United States track and field team have cancelled their pre-Olympic training camp in Japan because of concerns over the coronavirus pandemic.
Host city Tokyo is under a state of emergency amid a surge in cases, 10 weeks from the start of the Games.
American athletes were due to train in nearby Chiba and the local government said "concerns for their athletes' safety" led to the cancellation.
A recent poll found that nearly 60% of people in Japan want the Games to be cancelled, a fact that may have been exacerbated by the country's wish to offer donated vaccines to about 2,500 Olympic and Paralympic athletes and support staff to prevent an outbreak during the event.
In Japan, 2.6% of the population has been vaccinated and reports that athletes would be prioritised led to criticism from the public.

"Our officials are saying we'll make sure we don't cause trouble for the overall population," said Miho Kuroda of the Japan Paralympic Committee.
One sponsor has also responded to rising public concern in Japan, with a Toyota Motor Corp executive saying company officials felt "conflicted" over the Games.
"As sponsors, it breaks our heart to see public discontent aimed at athletes," Toyota's operating officer Jun Nagata said.
Despite maintaining the Games will go ahead the IOC president Thomas Bach earlier this week cancelled a trip to Japan because of surging cases of Covid-19.
Bach was to visit Hiroshima next week and meet the torch relay and then probably travel to Tokyo.
