SoftBank Group Corp. founder and CEO Masayoshi Son on Saturday expressed fresh doubt about Tokyo's delayed Summer Olympics going ahead during the COVID-19 pandemic.

"Currently more than 80% of people want the Olympics to be postponed or cancelled. Who and on what authority is it being forced through?" Son wrote in a Twitter post in Japanese.

The billionaire last week said he was "afraid" of holding the Olympics during the pandemic. Polls consistently show most Japanese people oppose holding the hames as planned.

The Reuters Corporate Survey on Friday showed that some 70% of big Japanese companies also want the Games delayed or cancelled, after the authorities postponed the event in 2020 for a year due to the pandemic.

But a top International Olympic Committee official said on Friday the games would "absolutely" go ahead even if the capital were still under a coronavirus state of emergency, given "all of the plans we have in place to protect the safety and security of the athletes and the people of Japan."
