Officials said the athlete was isolated at Tokyo’s Haneda airport. Four others traveling along with the athlete were reportedly transferred to a facility near the airport. They had been scheduled to travel to a training camp in Nanto in central Japan. Nanto officials said the training camp was likely to be canceled.
A second member of the delegation was found later to have the virus.
The first member who tested positive, after being in quarantine near Narita, again tested positive on Saturday after arriving in the Japanese town of Izumisano, according to a statement from the city.
Officials said the person was not believed to be contagious, and no contact tracing would be done.
Seiko Hashimoto, the president of the Tokyo organizing committee, said on Friday that more than 500 participants had arrived in Tokyo without incident. About 11,000 Olympic and 4.400 Paralympic athletes will arrive for the Olympics, in addition to tens of thousands of coaches, judges and Olympic officials. Many fear that the influx will drive up COVID-19 cases around the country.
Organizers still have not decided whether to allow local fans into venues. Fans from abroad were banned months ago.
Almost two weeks ago, organizers said they would allow indoor and outdoor venues to be filled to 50% of capacity up to 10,000.
But with new infections rising daily in Tokyo for two weeks, local organizers are expected to meet this week with the International Olympic Committee and others and lower the cap, or remove spectators altogether.
Tokyo reported 518 new cases on Sunday, marking the 15th straight day that infections have increased from levels of a week earlier. On Saturday, new cases reached 716, the highest in more than five weeks.
Former Prime Minister Shinzo Abe, who lobbied to land the Olympics, has lashed out at those opposing the games, calling them “anti-Japanese.”
“To make the Olympics a success holds historic meaning for Japan," Abe was reported as saying by the Mainichi newspaper. Abe blamed calls for canceling the Olympics on people “who are criticized as holding anti-Japanese views.”
Japan media have reported many possible scenarios, including: no fans at all; no fans at the opening ceremony on July 23; limits on fans at night events; dropping the limit at all venues to 5,000.
Dr. Shigeru Omi, a top government medical adviser, has said repeatedly that no fans is the safest option. He has also questioned why the Olympics are being held at all in the middle of a pandemic. He has termed it “abnormal.”
