The Japanese capital sees off stiff competition from Madrid
and Istanbul at the International Olympic Committee vote.
Tokyo is celebrating a stunning victory in the race to host the
Olympic and Paralympic games in 2020.
Madrid was eliminated in round one after initially finishing level on votes with Istanbul. A vote-off between the two cities saw the Turkish bid go through and the Spanish crash out. But the night predictably belonged to Tokyo.
Japan's strong track record of successfully hosting major sporting occasions - one summer Games, two Winter games and a football World Cup in 2002 - undoubtedly helped push votes their way.
The IOC's Evaluation Commission visited each city in March of this year and left Japan hugely satisfied with what it had seen.
Anti-government riots and protests across Turkey this year did not help Istanbul’s bid, while economic uncertainty hung over Madrid’s efforts from the outset.
Tokyo also had the emotional pull of the March 2011 earthquake and tsunami, showing that triumph can emerge from tragedy.
Their bid team were frequently asked questions about the Fukushima nuclear reactor and recent concerns about contaminated water leaking from it, but they dealt with them. The reactor is 155 miles away from the host city and their prime minister was on hand in Argentina to reassure the IOC in person.
None of the bids had a 'wow factor' delegate like London 2012 had when it landed the Games in July 2005 with David Beckham in attendance, but Tokyo can be rightly proud of what it has achieved.
For Madrid (four unsuccessful bids) and Istanbul (five defeats) this will have been a particularly bitter blow.
For Tokyo the party may be in full swing, but the hard work starts tomorrow
