Answer by taking a quote from the following article:

Mao Asada (Qian Tian  Zhen Yang , Asada Mao, born September 25, 1990) is a former Japanese competitive figure skater. She is the 2010 Olympic silver medalist, a three-time World champion (2008, 2010, 2014), a three-time Four Continents champion (2008, 2010, 2013), and a four-time Grand Prix Final champion (2005-06, 2008-09, 2012-13, 2013-14). She is the only female figure skater who has landed three triple Axel jumps in one competition, which she achieved at the 2010 Winter Olympics.

In September 2010, Nobuo Sato became Asada's new coach and Asada ended her relationship with coach Nagakubo.  After the Vancouver Olympics, Asada decided to relearn all of her jumps from scratch by getting back to basics. This contributed to her slump in the 2010-11 and 2011-12 seasons. Under the guidance of her new coach Nobuo Sato, she stripped her triple jumps to their rudimentary parts and relearned each takeoff and landing, beginning with a single rotation. While reworking her jumps, Asada did not skip any competitions in the 2010-11 season.  Asada was assigned to the 2010 NHK Trophy and the 2010 Trophee Eric Bompard ISU Grand Prix events. At the 2010 NHK Trophy, Asada placed 8th in both programs and finished 8th overall with a total of 133.40 points. At the 2010 Trophee Eric Bompard, Asada placed 7th in the short program, 5th in the free skating and 5th overall, scoring a combined 148.02 points.  At the 2010-11 Japan national championships, Asada was first in the short program and second in the free skating. She obtained a total score of 193.69 points and won the silver medal behind Miki Ando. At the 2011 Four Continents Championships, Asada placed second in both programs and won the silver medal with a score of 196.30 points, 5.04 points behind gold medalist Miki Ando. Her triple axel jump in free skating was ratified for the first time since 2010 Worlds Championship, with +1.29 grade of execution. At the 2011 World Championships, Asada placed 7th in the short program, 6th in the free skating, and finished 6th overall with 172.79 points.

Asada was first in the short program and second in the free skating. She obtained a total score of 193.69 points and won the silver medal behind Miki Ando.
