The organizers of the Tokyo Olympics, scheduled for the summer of 2020, admitted that the decision to postpone it for one year, would result in "very high" costs, and the task would be complicated and "unprecedented."

Postponing the Tokyo Olympics to the summer of 2021, at the latest, is a major logistical challenge for the organizers, while new deadlines for the world's largest sporting event have yet to be set.

"We have to make sure that the problems we face are solved one by one," said Toshiro Moto, chief executive of the Tokyo 2020 Olympics.

According to the Japanese daily "Nikkei", the delay could cost $ 2.7 billion, including site rental fees, changes to hotel reservations and additional fees for employees and security personnel, among other things.

And "Nikkei" quoted a source close to the file that these additional costs can be reduced according to the results of negotiations between the various parties.

Motu confirmed that the organizers would not give up their current plans but explained: "I think we have to go back a step back, sometimes you have to reconsider the plans."

Last December, the organizers estimated the total cost of the Tokyo Olympics at 1,350 billion yen (11.5 billion euros).
