(CNN) – 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.
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.
But Tokyo’s government has already amassed a $4.9 billion Olympic fund to pay to prepare for the Games, Hula said.
And a $1 billion national stadium that will be used for the athletic events and the Opening Ceremonies will already have been built for the rugby World Cup in 2017 and is not considered an Olympic expense.
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.
Turkey’s border with Syria also might have troubled some committee members, he said.
And this summer, the image of Turkish sport took a hit when about three dozen athletes tested positive for drugs, he said.
June’s rioting in Istanbul’s Taksim Square may also have tainted the city’s hopes, though Turkish Prime Minister Recep Erdogan tried to persuade IOC members ahead of Saturday’s vote.
Tokyo led after a first round of voting Saturday but fell short of a majority, with 42.
Istanbul and Madrid tied for second on 26 votes each and a 49-45 tiebreaker vote put the Turkish city in the final runoff with Tokyo.
Tokyo won the deciding vote, 60 to Istanbul’s 36, according to an IOC tweet.
