Hidayat knocked out of Japan Open badminton
The out-of-form fifth seed from  Indonesia, who has yet to win a title this season, struggled throughout the 53-minute match before losing 21-17, 12-21, 21-18.

"I couldn't play well at all. I couldn't find the way to attack. I've lost my confidence," said Hidayat, 30.

"I enjoyed playing badminton in the old days. I want to regain my form, but I'm not sure how long I continue to play."
