Istanbul, Tokyo and Madrid are the three remaining cities in the competition to become the host of the 2020 Olympic and Paralympic Games. Out of the three contenders, Tokyo is the only city to have already hosted the Summer Olympic Games, becoming in 1964 the first Asian city to do so. This is Madrid's third consecutive bid and Istanbul's fifth overall. Following the London 2012 Games, in 2016 Rio de Janeiro will host of the Summer Olympic Games, becoming the sports capital of the world between August 5 and 21 of that year.
