China enjoyed a dominant day at the International Table Tennis Federation (ITTF) Japan Open as the country clinched the men's and women's doubles titles in Tokyo.

Chen Xingtong and Sun Yingsha capped off their surprise run to the final by lifting the women's doubles crown with victory over Jeon Jihee and Yang Haeun of South Korea, the second seeds, at the Tokyo Metropolitan Gymnasium.

The unseeded duo, who had ousted top seeds Honoka Hashimoto and Hitomi Sato of Japan in the semi-finals, topped the podium with a 10-12, 8-11, 11-3, 11-7, 11-6 triumph.

China then continued their dominance as Ma Long and Xu Xin, the second seeds, beat team-mates Masataka Morizono and Yuya Oshima 11-7, 11-9, 6-11, 11-9 in the men's doubles final.

China's Fan Zhendong remains on course for a successful defence of his men's singles title as he progressed to the semi-finals of the tournament in the Japanese capital, which is due to host the 2020 Olympic and Paralympic Games.

The World Championships silver medallist earned a hard-fought 10-12, 7-11, 12-10, 11-4, 11-8, 11-6 victory over team-mate Liang Jingkun to reach the last four.

Fan, who won a doubles gold medal at the recent World Championships in Düsseldorf alongside Xu, had earlier battled to a 9-11, 9-11, 11-6, 11-9, 11-7, 11-3 win against Frenchman Emmanuel Lebesson.

The other last four clash will be between Ma and Xu, who will be on opposite sides of the table the day after sealing the men's doubles crown.

Ma, the reigning Olympic and world champion, beat Japan’s Koki Niwa 11-8, 12-10, 9-11, 11-5, 11-3, while Xu received a walkover due to an injury suffered by team-mate and opponent Fang Bo.

Second seed Chen Meng of China booked her place in the last four of the women's competition by beating Japan's fifth seed Miu Hirano 11-7, 11-8, 11-5, 11-7.

She will next face Germany's Han Ying, who upset fourth seed Cheng I-Ching of Chinese Taipei 11-7, 10-12, 11-4, 10-12, 11-8, 11-7.

China's Wang Manyu, who had to come through the qualification stage to reach the main draw, stunned Japan’s Mima Ito, the number eight seed, 4-11, 8-11, 13-11, 12-10, 11-9, 11-8 to progress to the semi-finals.

Sun Yingsha of China also progressed, ousting 10th seed Shan Xiaona of Germany 11-7, 4-11, 3-11, 11-9, 11-13, 11-8.
