Figure skater Takahashi announces retirement
TOKYO — Former world champion Daisuke Takahashi said Tuesday he has decided to retire from competitive figure skating, ending a career that brought Japanese male singles skating to world prominence.
“I am yet to decide what to do next. But I have decided to retire,” said the bronze medalist from the 2010 Vancouver Olympics.
“To move on with my life—and the remaining part of my life will be long—I needed to draw a line and retire from competition,” said Takahashi, who for years has struggled with nagging knee pain that has affected his recent performance.
