Artistic gymnastics great Kohei Uchimura, the 2012 and 2016 Olympic men's all-around gold medalist, looked back on his career with pride on Friday as he announced his impending retirement.

The 33-year-old, a six-time individual all-around world champion, said he will make one last appearance in a retirement event on March 12 at Tokyo Metropolitan Gymnasium, where he will give demonstrations on all six apparatuses along with other gymnasts.

"It hasn't really sunk in. I'm proud to have worn Japan's emblem for 16 of my 30-year career as a gymnast," Uchimura said during a news conference.
