Tokyo has been selected to host the 2020 Olympics. Not only will all the events be shown tape-delayed in the US because of the time difference, all the athletes will be forced to compete wearing protective gear. Cameras will be remotely controlled from underground bunkers.
On a more serious note, choosing Tokyo or any site in Japan now is a bad idea. The disaster at Fukushima is growing worse. Who knows what conditions will be like in seven years? Shortly after the earthquake and tsunami, the Japanese government consulted with the government of China about evacuating all of Tokyo and the surrounding area to an unpopulated area in a remote part of China.
