Here is an article I found translated into English in which Mao talks about retirement and how she feels about skating the last few years. I can't find the website anymore, so I am just pasting the content.
SAITAMA, Japan - Japanese figure skater Mao Asada said Sunday, the day after winning the world title, that she needed more time to decide when to retire from competition.
Asada, the runner-up to South Korean star Kim Yu-Na at the 2010 Vancouver Olympics, has kept her fans and skating officials in suspense by saying she had a "50-50 chance" of continuing to compete after this season.
"What I feel is that I need some rest now," the 23-year-old told reporters during an exhibition after the season-closing world figure skating championships in Saitama near Tokyo.
"I have struggled for three years as I could not skate the way I wanted and jump the way I wanted," she said.
"I had thought about staking my career on the Sochi Olympic season," she added.
In Sochi last month, Asada botched her trademark triple axel and other jumps. But she came back brilliantly in the free skate.
She improved further at the world championships before her home fans.
Asada broke Kim's short programme world record and topped the free skate section to win her third women's title following her triumphs in 2008 and 2010.
On Sunday, she said her free skating in Sochi and her overall performance in Saitama was the level she had been seeking to produce ever since Vancouver.
"I am finally beginning to really get a grip of how I can perform," she said.
"But you need to set a goal and have a lot of determination to stay on. If such things don't come out naturally, I don't think I can do it," she added. "I don't think there is any need for me to come to an immediate decision." Asada has been a poster girl for Japanese figure skating since winning her first Grand Prix Final title in 2005 to begin a longtime rivalry with Kim, a fellow 23-year-old.
