But the Japanese team failed to claim another gold-double a day after Ryoko Tani defended her title and Tadahiro Nomura won an unprecedented third straight Olympic gold, as Yuki Yokosawa had to settle for silver after a defeat to China's Xian Dongmei in the women's 52-kg final.

The 23-year-old Uchishiba, competing in his first Olympics, won all of his matches through ippon and dealt the decisive blow to Krnac after 3 minutes, 14 seconds at Ano Liossia Olympic Hall.
