Kosuke Kitajima of Japan had won gold in this event in 2004 and 2008, but had lost the 2011 World Championships to Hungarian Dániel Gyurta, who was also 2009 World Champion. Gyurta had finished second to Kitajima in 2004 at Athens but was fifth in Beijing. Kitajima was attempting to become the first man to three-peat in swimming at the Olympics, something he would attempted in the London 100 breaststroke.
Both qualified easily for the final in London. In the final Kitajima took it out fast, leading at 50 metres in 28.64, under the world record split. On the second lap, he was caught by Gyurta and Britain's Michael Jamieson, and Gyurta did not let up. He continued to push the pace and would finish in a world record 2:07.28. Kitajima could not maintain contact, but Jamieson remained close throughout, finishing for silver in 2:07.43, the fourth-fastest time ever. Kitajima was outtouched at the final wall for the bronze medal by his teammate Ryo Tateishi. Kitajima's attempt to three-peat in the 100 breast also came up short of the podium when he finished fifth.
