World Judo Championships

The World Judo Championships are the highest level of international judo competition, along with the Olympic judo competition. The championships are held once every year (except the years when the Olympics take place) by the International Judo Federation, and qualified judoka compete in their respective categories as representatives of their home countries. Team competitions have also been held since 1994. The men's championships began in 1956, though the format and periodicity of the championships have changed over time. The last edition of the championships took place in Astana, Kazakhstan in 2015.

The first edition of the world championships took place in Tokyo, Japan in 1956. There were no weight classes at the time and Japanese judoka Shokichi Natsui became the first world champion in history, defeating fellow countryman Yoshihiko Yoshimatsu in the final. The second world championship was also held in Tokyo two years later, with the Japanese winning the top two spots in the competition for the second time. In 1961, the championship was held outside Japan for the first time, and Dutch judoka Anton Geesink defeated the prior world champion, Koji Sone, in Paris, France, to become the first non-Japanese world champion.

The 1965 World Judo Championships were held in Rio de Janeiro, Brazil, and weight classes were implemented for the first time with the addition of the -68 kg, -80 kg, and +80 kg categories. Judo had become an Olympic sport at the 1964 Summer Olympics held in Tokyo, and a permanent sport after a brief absence at the 1968 Summer Olympics.
