Tokyo defeated Istanbul 60-36 in the final round of secret voting by the International Olympic Committee. Madrid was eliminated earlier after an initial tie with Istanbul.

Tokyo, which hosted the 1964 Olympics, billed itself as the reliable choice at a time of global political and economic uncertainty _ a message that resonated with the IOC.

"Tokyo can be trusted to be the safe pair of hands and much more," bid leader and IOC member Tsunekazu Takeda said in the final presentation. "Our case today is simple. Vote for Tokyo and you vote for guaranteed delivery. ... Tokyo is the right partner at the right time."

Tokyo had been on the defensive in the final days of the campaign because of mounting concerns over the leak of radioactive water from the tsunami-crippled Fukushima nuclear plant.
