With the Olympics now seven weeks away, pressure to cancel them continues to grow as Japan fights a fourth wave of the pandemic.
More than 15,000 competitors from around the world are due to arrive in Tokyo next month before the Games, which begin on July 23.
The Games were initially due to happen last year but were postponed in light of the pandemic. Now, locals want them either postponed again or cancelled completely. One recent survey, conducted by Asahi Shimbun, found about 80 per cent of local Japanese people do not want the global sporting event to proceed in July.
But despite mounting calls to cancel the games, the president of the Tokyo 2020 organising committee, Seiko Hashimoto, said the Games will still go ahead.
"We cannot postpone again," she said in an interview published on Thursday in the Nikkan Sports newspaper.
It comes after 10,000 of 80,000 unpaid volunteers have reportedly quit the Olympics and Paralympics, with some dropping out over concerns about COVID-19.
"We have not confirmed the individual reasons," organisers said in a statement, according to the ABC.
"In addition to concerns about the coronavirus infection, some dropped out because they found it would be difficult to actually work after checking their work shift, or due to changes in their own environment."
Last month, the CEO of Japan's top e-commerce company told CNN the Olympic Games were a "suicide mission" for Tokyo.
"It's dangerous to host the big international event from all over the world. So, the risk is too big," Hiroshi Mikitani said. "The upside is not that great, and we see many countries are still struggling so much, including India and Brazil. And it's not time to celebrate yet."
