Keiko Ikeda

Keiko Tanaka-Ikeda is the first Japanese female gymnast to win a world title, which she accomplished on the balance beam in 1954. For 63 years, she remained the only Japanese female gymnast who won a world gold medal - until Mai Murakami won the floor exercise at the 2017 World Championships. Tanaka-Ikeda won seven more medals at the world championships in 1958–1966. She also competed at the 1956, 1960 and 1964 Olympics in all artistic gymnastics events and won a team bronze medal in 1964; her best individual achievement was a fourth place on the floor in 1956.
