TOKYO - An overseas athlete has tested positive for COVID-19 after arriving in Tokyo ahead of the Olympic Games, organizers said on Thursday.

The Tokyo 2020 organizing committee said that the athlete, who tested positive on Wednesday, was observing a 14-day period of self-isolation and has not entered the athletes' village, Japan's state broadcaster NHK reported.
