Tokyo 2020 organising committee president Yoshiro Mori expects the new date for the postponed Olympic Games to be decided this week.
The Games, which were due to be held in Japan from July 24 to August 9, have been postponed until 2021 due to the coronavirus pandemic.
Mori says suggestions have been made to hold the games either in spring or summer next year and he confirmed he would likely discuss the matter with International Olympic Committee president Thomas Bach this week.
“Opinions on both sides have been compiled, whether spring or summer, there are opinions for both options,” said Mori.
“They both have advantages and disadvantages that are being compared, and then will be decided.
“This has also been reported to Chairman Bach. We expect to hear from Chairman Bach most likely this week.”
World Athletics president Lord Sebastian Coe has suggested the 2021 World Championships could be delayed by a year to accommodate the Tokyo Games.
The next Athletics World Championships are scheduled to take place in Eugene, Oregon in August 2021 but Coe says the event may need be moved to avoid clashing with the Olympics.
“At this stage, it’s fair to say nothing is on the table, nothing is off the table,” he said.
