The 2020 Games, postponed for a year due to the global pandemic, is being held mostly without spectators and under tight quarantine rules.
Japans public has been lukewarm about the Games amid a resurgence in new coronavirus infections and worries that an influx of visitors may create a super-spreader event, straining an already-stretched medical system. Only around 20 per cent of the population is fully vaccinated.
Tokyo 2020 President Seiko Hashimoto acknowledged the publics concerns.
I understand that there are still many worrying factors. Organisers must try to make sure that people will understand that these games are safe and secure, she told a news conference on Saturday.

So far, more than 40 people involved in the Games, including both domestic and foreign nationals, have tested positive. The latest case is the first at the 44-hectare athletes village on Tokyos waterfront, which is where a majority of the 11,000 competitors will be staying.
Athletes are just starting to arrive for the Games which run July 23 through August 8.
