Mima Ito and Jun Mizutani's epic gold-medal win in the mixed doubles table tennis final at the Tokyo Games exposed cracks in the wall of dominant China and has also provided a perfect end to Mizutani's career.

Ito, 20, and Mizutani, 32, stunned Chinese world champions Xu Xin and Liu Shiwen 4-3, having trailed by two games in a nerve-jangling contest, giving Japan its first ever table tennis gold at an Olympics.

Japan became the first champions of the mixed doubles event that was added to the table tennis program for the first time at these games, denying China a clean sweep.
