Tokyo 2020 head acknowledges anti-Games petition

The online campaign has made rounds on social media over the last week, reflecting how the public feel about the feasibility of the Olympic Games.

"We are working on creating a bubble, calculating the limiting of movement, not adding stress to local medical institutions, and listening to experts' opinions and adjusting accordingly (for the Games)," Hashimoto said.

Public opposition to the Games has been growing as Japan faces a fourth wave of COVID-19 infections just 10 weeks before the event.

Japan has added three more prefectures on Friday to join Tokyo, Osaka, and four other prefectures under a COVID-19 state of emergency until May 31.
