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 (July 2011) and from the United States Judo Federation (USJF) (September 2011), and was the last surviving student of Kanō Jigorō, founder of judo. She was a renowned pioneer of women's judo, together with her senpai Masako Noritomi (1913–1982) being the first woman promoted to 6th dan (c. 1972). In 2006 the Kodokan promoted Fukuda to 9th dan. She is also the first and, so far, only woman to have been promoted to 10th dan in the art of judo. After completing her formal education in Japan, Fukuda visited the United States of America 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. Early life Fukuda was born on April 12, 1913, in Tokyo. Her father died when she was very young. As a youth, she learned the arts of calligraphy, flower arrangement, and the tea ceremony; typical pursuits for a woman in Japan at that time. Despite her conventional upbringing, Fukuda felt close to judo through memories of her grandfather, and one day went with her mother to watch a judo training session. A few months later, she decided to begin training for herself. Her mother and brother supported this decision, but her uncle was opposed to the idea. Her mother and brother had thought that Fukuda would eventually marry one of the judo practitioners, but she never married, instead becoming a judo expert herself. Fukuda's grandfather, Fukuda Hachinosuke, had been a samurai and master of Tenjin Shinyō-ryū jujutsu, and he had taught that art to Kanō Jigorō, founder of judo and head of the Kodokan. Kanō had studied under three jujutsu masters before founding judo, and Fukuda's grandfather had been the first of these men. Kanō had taught female students as early as 1893 (Sueko Ashiya), and had formally opened the joshi-bu (women's section) of the Kodokan in 1926. He personally invited the young Fukuda to study judo—an unusual gesture for that time—as a mark of respect for her grandfather. She began training in judo in 1935, as one of only 24 women training at the Kodokan. Apart from instruction by judo's founder, Fukuda also learned from Kyuzo Mifune.
