Inoue defeated Nicolas Gill of Canada in the final. He carried a photo of his mother, who had died one year prior to the Games, onto the podium. "To me, she was the best mother in the world and I wanted the world to see her," Inoue said at the time.

"We look at judo not only as a sport but as a 'budo,' or martial way," Inoue tells CNN. "There is the competition -- we come to a World Championships and aim to win a gold medal -- but there is something far bigger behind this."
