The International Olympic Committee (IOC) will face “several hundred million dollars” of added costs because of the postponement of the Tokyo Games, the body’s president Thomas Bach said in an interview with German newspaper Die Welt on Sunday.

Estimates in Japan put the overall cost at $2 billion-$6 billion. Except for the IOC portion, all added costs will be borne by the Japanese side, according to an agreement signed in 2013 when Tokyo was awarded the Olympics.

Bach said it was “impossible to say for now” the extent of the added costs for the IOC caused by the pandemic.

“We agreed with the Prime Minister that Japan will continue to cover the costs it would have done under the terms of the existing agreement for 2020, and the IOC will continue to be responsible for its share of the costs,” Bach said. “For us, the IOC, it is already clear that we shall be faced with several hundred million dollars of additional costs.”

Before the postponement, Japanese organisers put the official cost of the games at $12.6 billion. However, a government audit report in 2019 said the costs were at least twice that. All but $5.6 billion of it is in taxpayer money.

On Friday, the CEO of the Tokyo organising committee said the coronavirus pandemic left some doubts about the Games going ahead next year.

“I don’t think anyone would be able to say if it is going to be possible to get it under control by next July or not,” Toshiro Muto said, speaking through an interpreter. “We certainly are not in a position to give you a clear answer.”
