When did women join judo?

In 1923, Jigoro Kano opened a women’s section of the Kodokan. He focused on the technical study and on kata but did not allow the practice in competition which was considered dangerous to the health of future mothers. Keiko Fukuda, granddaughter of Hachinosuke Fukuda, who taught Jujutsuto Kano, dedicated her life to spreading women’s judo worldwide.
