Figure skating-Japan's Asada retiring, has lost 'will to compete'

TOKYO, April 11 (Reuters) - Japanese figure skater Mao Asada, a silver medallist from the 2010 Winter Olympics and three-time world champion, is retiring from the sport after a disappointing season, saying she has lost the will to compete.

The 26-year-old took a year off from competition before resuming training in 2015, but said on her blog late on Monday that this time she was quitting for good.

"After coming back to competition, I have not been able to achieve either the techniques or the results I wanted, and the number of things I worried about increased," wrote Asada, known in Japan by the affectionate nickname "Mao-chan."

"After last year's Japan nationals, all the goals that had kept me going disappeared, along with my will to compete."

Plagued by knee pain this past season, Asada finished 12th at the national championship in December, the lowest finish of her career. She had previously won the event six times.

Asada began skating at the age of five, lured into the sport by her older sister Mai, and began to draw attention while still a junior, sharing the limelight with South Korea's Kim Yuna at the start of a long rivalry.

This climaxed at the 2010 Games, when Asada had to settle for silver while Kim claimed gold.

The only woman to land the complicated triple Axel jump three times in competition, Asada was tipped as a leading medal contender at the 2014 Sochi Olympics but had a disastrous short programme, although she rebounded with a strong free skate to finish sixth overall.

She won her third world championship a month later, setting a world record with the same short programme that had been her undoing at Sochi, but wrote that she did not regret either taking a one-year break or coming back for another go.

"I have no regrets about my skating career," she added.

"This was a huge decision for me, but I regard it as only one stage of my life and will find new dreams and goals going forward." (Reporting by Elaine Lies; Editing by Peter Rutherford; )
