Critics of Japan’s plan to hold the Tokyo Olympics despite the fourth wave of coronavirus infections submitted a petition on Friday calling for the games to be cancelled.

Three hundred and fifty thousand people signed the petition over nine days.

‘Stop Tokyo Olympics’ campaign organiser Kenji Utsunomiya said the global festival of sports should take place only when Japan can welcome visitors and athletes wholeheartedly.

The Games was postponed from 2020 due to the coronavirus pandemic.

“We are not in that situation, and therefore the games should be cancelled,” he told a news conference. Precious medical resources would need to be diverted to the Olympics if it’s held.”

The petition was submitted to the Olympic and Paralympic committee chiefs and Tokyo Governor Yuriko Koike.

It came as Japan added three more areas to a state of emergency, now covering Tokyo, Osaka and four other prefectures amid surging case numbers.

This has come exactly 10 weeks from the scheduled July 23 opening of the Olympics.

Asked about the campaign against the Games, Tokyo Governor Koike said she would work towards a “safe and secure” Olympics.

“Though there is a global pandemic, it is important to hold a safe and secure Tokyo 2020 Games,” she told a news conference.

The new areas under the state of emergency include Hokkaido prefecture, where the Olympic marathon will occur after it reported a record high of 712 new coronavirus cases on Thursday.

Nationwide, Japan has seen about 656,000 confirmed cases, with 11,161 deaths.

Opposition to the event has also come from doctors, while some high-profile Japanese athletes have expressed concern.

These include Masters golf champion Hideki Matsuyama and top women’s tennis player Naomi Osaka.

Business leader Masayoshi Son, chief of SoftBank Group Corp, added his voice to the chorus of trepidation on Thursday.

He said in unusually blunt remarks he was afraid of what might happen if the Games went ahead.

Dozens of towns that had been due to host visiting athletes at pre-games events have already cancelled those plans.

They said they could not guarantee medical help amid strains on the health system.

Economy Minister Yasutoshi Nishimura, when asked whether the Games would go ahead in spite of the increase in COVID cases, said the decision was out of their hands.

He said organisers were looking to the International Olympic Committee (IOC) for backing for the event.

“I am aware that many are concerned that it will lead to an outbreak of cases,” Nishimura told parliament.

“The organisers are currently working together closely, based on the decision by the IOC to hold the Tokyo 2020 Olympics,” the minister said.

Organisers are determined to host the event with coronavirus mitigation measures in place.

A skateboarding event on Friday was the latest test for their precautions.

Organisers told journalists after the event that athletes and coaches had been told to follow measures and avoid the usual celebratory hugs and cheers on the sidelines.

“This kind of behaviour is not OK in terms of COVID-19 measures,” said Yasuo Mori, the deputy executive director of Tokyo 2020’s operations bureau.

“We’d usually take videos together, but now we have to stay masked and two metres apart,” said skateboarder Ryuto Kikuta, 17, adding that he understood the measures were necessary, but they still felt strange.

Spectators will not be allowed in from abroad, while a decision on Japanese-based spectators has yet to be made.

With the latest emergency measures, 19 out of Japan’s 47 prefectures fall under restrictions that include closures of eateries by 8:00 p.m. and a ban on alcohol at bars and restaurants.
