International Olympic Committee chief Thomas Bach's planned visit to Japan in mid-May will be "very difficult" amid a resurgence of COVID-19 infections in the country, the head of the Tokyo 2020 Organising Committee said Friday.

Seiko Hashimoto said at a regular news conference that the situation is not favorable for him to visit Japan given that Tokyo has been under a state of emergency since late last month.

"I think it is very important to have President Bach look at the current situation. However, when the state of emergency will be extended, it will likely cause a huge burden on him to visit during that period," Hashimoto said.
