The Japanese players fought manfully throughout, playing in the country’s maiden final in the competition, but ultimately had few answers to the onslaught of their Chinese opponents.
The match started with a tight men’s contest in which the Chinese pair of Fu Haifeng and Zhang Nan needed 79 minutes to overcome Hiroyuki Endo and Kenichi Hayakawa, eventually triumphing 21-17, 20-22, 21-17.
World number one Li Xuerui was pushed hard by Akane Yamaguchi in the first game, but ultimately the top seed’s greater shone through as she won 23-21, 21-14.
"Because it's a big contest, I felt pressure. The reason why the score was so close in the first game was because I made a few mistakes," Li told reporters after the game.
The Chinese victory was confirmed when world number two men’s player Lin Dan, outplayed Japan's Takuma Ueda 21-15, 21-13.
