Madrid was eliminated in the first round of vote (though tied with Istanbul and needed the vote for tie-breaker).
Istanbul was eliminated in the final vote. The vote tally, according to Asahi, was 60 to 36.
I'm more curious to know why Madrid and Istanbul lost, rather than why Tokyo won.
The UK's Telegraph commented the choice was about "least bad". Some may disagree and ask if that was the case why Madrid was eliminated in the initial round (the country didn't suffer a nuclear accident, and it is far away from Syria).
Move on to the next vote, this time in the US Congress on Syria, which may come as soon as Monday.
