While the International Olympic Committee said on Thursday it was committing $650 million toward expenditures for the delayed 2020 Tokyo Games, organizers are not ready to say whether the amount would be enough.

"In terms of the additional costs (caused by the postponement), it's still under heavy evaluation and we are not quite to the point of making an estimate," Tokyo 2020 CEO Toshiro Muto said when asked during an online news conference on Friday afternoon.

Muto said the IOC did not provide a breakdown of how the money was to be allocated. He also mentioned it was the IOC that decided the amount.
