"Tokyo 2020 will continue to work closely with Okinawa prefecture and the local task forces in all other prefectures due to host Olympic Torch Relay segments in order to ensure that these events will be safe and secure for all local communities" the organising committee said in a statement.
The relay, due to reach Osaka in mid-April, is seen as the first major test of Games organisers' abilities to hold a large event under strict coronavirus curbs. It features 10,000 runners carrying the torch through all Japan's 47 prefectures.
The western metropolis of Osaka is grappling with a spike in coronavirus cases and the governor of Osaka prefecture has called for cancelling the leg that takes place in the city.
There are no plans to discuss Mori's resignation at the meeting but he could face criticism over his comments, Nikkan Sports said in a separate report.
"We are taking this very seriously," Olympic Minister Seiko Hashimoto said on Tuesday when asked about the resignation of the volunteers.
Organisers have been assessing the financial impact of the delay since the Japanese government and International Olympic Committee (IOC) decided in March to postpone the Games until 2021.
