Duncan Mackay of the insidethegames website has told the BBC's Dan Roan that Tokyo winning the bid to host the 2020 Olympic and Paralympic Games is ''a bit of an upset".
The Japanese capital won a final round of voting by International Olympic Committee (IOC) members in Buenos Aires to beat Istanbul by 60-36 votes.
Madrid had earlier been eliminated in a first-round ballot.
