On Jan. 7, Tokyo put in its bid to host the 2020 summer Olympic Games. So did Madrid and Istanbul. Who wins the coveted bid will not be known until September. But consider some of the barriers to Tokyo winning.

Second, many people feel Japan should instead be committing itself to speeding up the lymphatic government cleanup and rebuilding of the Tohoku earthquake and tsunami disaster area.
