Stand Up Japan was an event a few days ago held in Japan that was featuring some of the biggest names in Japan's combat sports in exhibition bouts. The two big names at the event were KID Yamamoto and Masato. Masato retired at the ripe age of 30, during the peak of his career and did it on his own terms. Masato retired as a legend, while Yamamoto continues to fight past what many consider his prime and has had no success in the United States fighting for the UFC.
Daniel Herbertson of AOL's MMAFighting.com was live at the event and captured it on video, so sit back and watch clips from this great event. [source]
