Keiko Fukuda, Japanese-American martial artist and trainer (born 1913)

Keiko Fukuda was a Japanese-American martial artist. She was the highest-ranked female judoka in history, holding the rank of 9th dan from the Kodokan (2006), and 10th dan from USA Judo and from the United States Judo Federation (USJF), and was the last surviving student of Kanō Jigorō, founder of judo. She was a renowned pioneer of women's judo, and in 1972 together with her senpai Masako Noritomi (1913–1982) was one of the first two women promoted to 6th dan. In 2006, the Kodokan promoted Fukuda to 9th dan, making her the first woman to hold this rank from any recognized judo organization. She is also the first and, so far, only woman to have been promoted to 10th dan in judo, which occurred in 2011. After completing her formal education in Japan, Fukuda visited the United States to teach in the 1950s and 1960s, and eventually settled there. She continued to teach her art in the San Francisco Bay Area until her death in 2013.
