is a Japanese freestyle wrestler. She has won five FILA Wrestling World Championships and two Olympic Bronze medals in the 72 kg weight class.

She is sponsored by Japan Beverage Inc. and was nominated by the Japanese Olympic Committee's Special Athlete Campaign.

Her father is professional wrestler Animal Hamaguchi, who is known for his emotional displays during Kyoko's matches. Although Kyoko has long wanted to follow in her father's footsteps and enter the professional game, the lack of a stable women's circuit since the collapse of All Japan Women's Pro-Wrestling has kept her from doing so.

Profile 
She swam while in junior high school. At the age of fourteen, she decided that she wanted to be a female professional wrestler and trained in the Animal Hamaguchi's Wrestling Dojo.

She has won the Japan Championship every year from 1996 to 2006, and has won the World Championships five times. In both the 2004 Athens Olympics and the 2008 Beijing Olympics, she won a bronze medal in the 72 kg class. She was also a flag bearer for the Japanese team in the opening Olympic ceremonies in 2004.
