Another major development in Judo’s history was the inclusion of women. The first Women’s World Judo Championships were held in New York City in 1980, and women’s Judo became a demonstration sport at the 1988 Seoul Olympics.
The 1950s and 1960s were key decades for Judo’s growth. In 1956, the first World Judo Championships took place in Tokyo, with 21 countries participating.
