JSC may stand for joint steering committee, or one of the following:

Daisuke Takahashi (髙橋 大輔, Takahashi Daisuke^?, born March 16, 1986) is a Japanese figure skater, notable as the 2010 Olympic bronze medalist, the 2010 World Champion, a two-time (2007, 2012) World silver medalist, a two-time (2008, 2011) Four Continents Champion, and a five-time (2006-2008, 2010, 2012) Japanese national champion.

Takahashi represented Japan at the 2006 Winter Olympics and at the 2010 Winter Olympics. His bronze medal at the 2010 Winter Olympics was the first Olympic medal for Japan in the men's singles event.

Born in Kurashiki, Okayama Prefecture, Japan, Takahashi began figure skating when he was 8 years old. When a skating rink was built near his house, he went with his mother to watch the skaters at the rink, and afterwards, enrolled in the figure skating club. His mother intended for him enroll in the ice hockey club, but he didn't like the protective gear of ice hockey, so he enrolled in the figure skating club, instead.

Takahashi had a successful junior career, winning the 2002 World Junior Championships, in his first, and only, appearance at that competition. Takahashi is the first Japanese man to have won the title.

Akiko Suzuki (鈴木 明子, Suzuki Akiko^?) (born March 28, 1985 in Toyohashi, Aichi, Japan) is a Japanese figure skater. She is the 2012 World bronze medalist, a two-time Grand Prix Final medalist (2011 silver, 2009 bronze), the 2010 Four Continents silver medalist, a two-time Japanese national silver medalist, and the 2007 Winter University Games Champion.

Suzuku trains in Nagoya, Japan. After her competitive career, she would like to become a choreographer. She suffered from anorexia nervosa and therefore missed the entire 2003–2004 season of skating. Suzuki works for Toho Real Estate which has its own skating rink.

Suzuki won the bronze medal at the 2001–2002 Junior Grand Prix Final. After having a successful junior career, Suzuki was hampered by her struggles with an eating disorder which began at age 18 when she left home for university. Her weight having fallen to 32 kg, she was unable to jump and missed the entire 2003–2004 season. It took her a year to gain back the weight she had lost. Suzuki returned to competitive skating in the 2004–2005 season after being inspired by Shizuka Arakawa's victory at the 2004 World Championships.

Mao Asada (浅田 真央, Asada Mao^?, born September 25, 1990) is a Japanese figure skater.

She is the 2010 Winter Olympic silver medalist, a two-time (2008 & 2010) World champion, a two-time (2008 & 2010) Four Continents champion, a two-time (2005–2006 & 2008–2009) Grand Prix Final champion, the 2005 World Junior champion, the 2004–2005 Junior Grand Prix Final champion and a five-time (2006–2009, 2011) Japanese national champion.

At the 2010 Winter Olympics, she became the first woman to land three triple axel jumps in the same competition.

Mao Asada was born in Nagoya, Aichi, Japan. She was named after the Japanese actress Mao Daichi. She attended Nagoya International School until the middle of 1st grade. After transferring, she graduated from Takabari Elementary School and Takabaridai Junior High. She received her high school diploma from Chukyo High School on March 15, 2009.
