Seiko Yamamoto is a Japanese wrestler who won four world titles and two Asian Wrestling Championships in her career.
She was born on August 22, 1980, in Kawasaki, Kanagawa, Japan.
Seiko’s father is Ikuei Yamamoto, who also competed in the Olympics as a wrestler. Her older brother is mixed martial artist Norifumi Yamamoto.
In four years from 1999 to 2003, she collected four gold medals at the World Wrestling Championships.
