Organisers have warned overseas athletes, officials and journalists attending the games against visiting restaurants that open after 8pm or serve alcohol, citing concerns over the possible spread of Covid-19.
Japan has declared a state of emergency for Tokyo that will run through its hosting of the Games and public concern has grown over what impact the influx of tens of thousands of attendees could have on infection rates.
Japanese media have reported cases of people accredited for the Games drinking in Tokyo’s downtown areas or violating quarantines.
“Even after your first 14 days in Japan, this will be perceived as visiting a business that operates illegally and could constitute a grave reputational risk to yourself, your organisation, and the Tokyo 2020 Games,” organisers said in a note sent to Covid-19 liaison officers responsible for ensuring the participants follow the protocols.
Meanwhile, Czech beach volleyball trainer Simon Nausch is the third member of the Czech delegation to test positive for Covid-19, bringing the total number of positive cases to 71.
Beach volleyball player Ondrej Perusic recorded a positive test on Monday, two days after a staff member had tested positive following their arrival in Tokyo on a charter flight from Prague.
Nausch and Perusic have both left the Olympic village to isolate.
