Koji Yamamuro is a 2012 Olympian representing Japan.
Yamamuro is solid on all the events, but stands out the most on still rings and vault. His difficulty score of 6.7 on still rings puts him in position to win a medal in London. He is the reigning World all-around bronze medalist.
The Japanese men's team will also look to overthrow defending Olympic champion China. Yamamuro's performances will be key in achieving this.
At the 2011 World Championships in Tokyo, Yamamuro represented his country well in front of a home crowd. He competed four events in the team final, helping Japan fend off the U.S. team for second place.
Individually, Koji won a pair of bronze medals at those Worlds, placing third in the all-around final and also on rings.
Koji burst on to the scene at the 2010 World Championships in Rotterdam, helping the Japanese men to a silver medal behind powerhouse China. He also qualified to the still rings final, ending up in fourth place.
