Tokyo has been chosen by the International Olympic Committee to host the 2020 Summer Games.

In voting Saturday in Buenos Aires, the committee picked Tokyo over the two other contenders, Madrid and Istanbul.

Tokyo previously hosted the Summer Games in 1964.

Japan’s bid for 2020 billed the city as the safe choice — despite radiation leaking from the Fukushima nuclear plant. Prime Minister Shinzo Abe personally made a presentation to the committee and promised an effective cleanup.

“A safe and secure Olympic Games will be staged by us — I think that was another hope for their support. I would like to pledge that we will be discharging this responsibility.”

Abe said Tokyo would try to stage a successful Games to thank the world for its support after the 2011 earthquake and tsunami that devastated parts of Japan.

Tokyo’s bid came in at $5 billion to $6 billion, compared to $19 billion pledged by Istanbul, said Ed Hula, editor and founder of aroundtherings.com, which covers the business and politics of the Olympic movement.

Turkey would have been the first Muslim country to host the Games, and with a median age of less than 30 years, one of the youngest. However, it missed out for the fifth time.

On Sunday, the three sports competing to be added to the 2020 roster will know their fate.

Squash is hoping to be included for the first time, but is up against a combined baseball/softball bid and wrestling — which is seeking to be reinstated.

The 2016 Summer Olympics will be in Brazil. The Winter Olympics will be held in Russia in 2014 and South Korea in 2018.
