Japanese mixed doubles pair Jun Mizutani and Mima Ito ended years of Chinese dominance to win their country's first-ever table tennis Olympic gold Monday.

China had won every Olympic title in the sport since a men's singles triumph for South Korean Ryu Seung-min in the 2004 Athens Games, but Xu Xin and Liu Shinwen blew a two-game lead in a thrilling final in Tokyo.

Mizutani and Ito raced into an 8-0 lead in the deciding game and closed it out when Xin hit a return into the net, with the Japanese pair winning 5-11, 7-11, 11-8, 11-9, 11-9, 6-11, and 11-6.

Liu and Xu, the reigning world champions, looked shocked by their defeat as their opponents celebrated a famous triumph.

The victory also sent the host nation to the top of the overall Olympics medals table at the end of the day's action with eight golds, one more than the United States.

It was only the fifth time in 33 Olympic table tennis competitions that China have failed to finish on the top step of the podium.

Second seeds Mizutani and Ito had been on the brink of a quarterfinal exit on Sunday against German duo Patrick Franziska and Petrissa Solja, but saved seven match points to win 16-14 in a seventh game.

This was the first time the mixed doubles event had been played at the Olympics. Cheng I-ching and Lin Yun-ju secured bronze for Taiwan with an 11-8, 11-7, 11-8, 11-5 win over French pair Emmanuel Lebesson and Yuan Jia Nan.
