Tokyo overcame fears of the dangers of radiation-contaminated water from the Fukushima Daiichi nuclear power plant, crippled by the March 2011 earthquake-tsunami disaster, about 250 kilometers northeast of the city to win the vote.
Prime Minister Shinzo Abe assured IOC members that the situation was under control.
He stressed "It has never done, and will never do, any damage to Tokyo."
I'm very proud that my country has been chosen.
And I hope this Olympic will help reconstruction of 2011 East Japan Earthquake.
Everybody in the world, please come and enjoy 2020 Tokyo Olympic!!
