Anyone arriving in the Japanese capital from overseas for the Games are forced to undergo a two-week quarantine period as part of measures by organisers to combat the spread of coronavirus.

This includes filling out an activity plan where visitors must state which Tokyo 2020 venues they plan to go to during their first 14 days in Tokyo.

COVID-19 liaison officers were informed in late June that members of their organisation will be allowed to leave their hotel for 15 minutes each day to gain essentials from a nearby convenience store.

There have recently been reports of accredited people drinking in bars and restaurants, causing concern among the Japanese public.

Masa Takaya, spokesperson for Tokyo 2020, revealed organisers have now decided to scrap the 15-minute policy but have warned visitors against drifting too far away from their hotels.

"We have someone at each of those [hotels] but if it is necessary to go out anywhere in a short time, like in order to go to the convenience store in case the building does not have facilities for food, we still have to provide a certain level of those elements for those media who are under the 14-day quarantine period," said Takaya.

"There will now be no 15-minute rule but what we want to make sure is that thorough countermeasures are in place.

"If you need to go out, even for a minute to get your meals, you need to just tell your security person at the entrance to say your name and room number.

"Under his or her surveillance you can of course go into a convenience store to buy your meals and come back as quickly as possible.

"There is no clear definition that it has to be within 15 minutes.

"For a close contact, there is a 15-minute rule.

"If it is necessary to get meals, you need to get access to the convenience store outside the building, you just need to be within the sight of the security person.

"It’s not like the security person will keep following you, it’s not like that but we still have to say to the citizens in the local area that the 14-daty quarantine is in place.

"Even if you have to go to a restaurant even for a short minute, you will have to be under the sight of this security person."

Japan is under a state of emergency due to rising COVID-19 cases, with Tokyo reporting 1,979 new infections in the past 24 hours - the highest daily tally since January 15.

The number of confirmed COVID-19 infections in Japan among those connected to the Games since July 1 now stands at 92.

Tokyo 2020 officials had previously warned the Japanese public would share on social media pictures and evidence of Olympic-accredited people breaching the rules.

Tsuyoshi Iwashita, head of security for Tokyo 2020, admitted the 15-minute rule was leading to "some misunderstanding".

But he has reiterated the importance of visitors adhering to the COVID-19 protocols to avoid facing possible sanctions.

"When we identify those breach we are trying to identify them as quickly as possible and sometimes we have to treat them accordingly," said Iwashita.

"Any playbook violations identified there will be [either] a suspension of accreditation or warnings.

"I would like to take this opportunity to ask all the people in this Games please comply with the rules."

Hidemasa Nakamura, Games delivery officer for Tokyo 2020, confirmed that about 32,000 people including athletes and shareholders have arrived in Japan for the Games since the start of July with 20 of those testing positive for coronavirus upon arrival.

He said the usual rate of infection was 2.4 per cent compared to 0.06 per cent for Olympic attendees, claiming this was down to the playbooks, vaccinations and the undertaking of at least two tests prior to departure.

According to Nakamura, 96,000 screening tests had been conducted with 87 positives including 35 from overseas and 52 from Japan.

"The measures are working fully," said Nakamura.

"We believe that we comply with the playbook and the Games is safe and secure."
