While the country is cautiously reopening its economy, with professional baseball, football and sumo resuming in front of limited numbers of fans, the nation continues to see a steady stream of new coronavirus cases.
Japan has already ploughed billions of dollars into the Olympics, with the delay only adding to the cost.
Coates said the IOC was doing its part, putting in “something like an extra $800 million to support the international federations, whose income isn’t happening this year, and national Olympic Committees”.
As Japan, the IOC and thousands of athletes wait to see whether the Olympics go ahead next year, the ceremonial Games flame — centrepiece of the aborted torch relay — is on display in a Tokyo museum.
A set of giant Olympic rings, weighing 69 tons and measuring 15 by 32 meters, was towed away for maintenance, and last month Tokyo’s National Stadium, rather than hosting Olympic track and field, staged the much lower-key Golden Grand Prix 2020 behind closed doors.
