Yuzuru Hanyu is the first man to enter an Olympics as the reigning gold medalist and reigning world champion since Dick Button did so in 1952. Its yet another impressive feat from Hanyu, who topped the field in 2014 to become the youngest Olympic gold medalist since Button. Hanyu was also Japans first-ever mens Olympic gold medalist. He has two world championship titles and was the first man to win four consecutive Grand Prix Final titles. This Olympic season has been the most challenging for Hanyu yet.
