Japan had no choice but to scrap their initial Olympic Stadium plans due to high construction costs, IOC president Thomas Bach said.
International Olympic Committee (IOC) president Thomas Bach has defended Tokyo 2020 organisers after they scrapped initial plans for their Olympic Stadium.
Japanese prime minister Shinzo Abe revealed earlier this month that Zaha Hadid Architects' original design was to be thrown out, after reports costs had reached over 2billion.
And following the IOC executive board meeting in Kuala Lumpur, Bach claimed the decision would save Japan $1.7bn.
"The IOC is respecting the fact that we have seen dramatic changes, compared to the time of bidding by Tokyo 2020," Bach said on Wednesday.
"The construction costs, for different reasons, have just gone through the roof - not only for the stadium, but construction costs in Japan in general.
"These are circumstances which are beyond the control of the organising committee and of the government, which is why we are respecting this decision.
"Tokyo will have a state-of-the-art stadium with best possible conditions for athletes and spectators."
With just over a year to go until the next summer Olympics, Bach said he was confident Rio 2016 was on target to deliver - despite organisers conceding they had hurdles to climb.
"The focus were, of course, the upcoming Olympic Games," Bach said of their two-day board meeting.
"We got an update on the latest progress in regard to construction of the different venues, including the Olympic Village. We heard they're preparing very well.
"We've also been talking about the challenges Rio is facing.
"On the one hand, we see great progress. On the other, there is no time to lose.
"Given the fact the organising committee have acknowledged these challenges, we're very confident we'll have a great Games one year from now, because acknowledging challenges is the first and most important step to overcome them and to address them."
