Brazil has a major presence in the World Judo Championships. Rio de Janeiro first hosted the competition in October 1965, which was only the fourth edition of the championships. Although Brazil did not medal, this initial meeting would pave the way for future events. At the seventh edition of the Championships held in Ludwigshafen, West Germany, in September 1971, Brazilian judoka Chiaki Ishii earned the first World Judo Championship medal for Brazil. Since then Brazil has earned several medals. João Derly however, is Brazil's only judoka to become a two-time world champion, winning the 2005 and 2007 World Judo Championships consecutively, the latter of the two hosted at Rio de Janeiro's HSBC Arena. This event marked the first time that Brazil had hosted a mixed-gender World Judo Championship. Brazil ranked second overall in medals behind Japan at the 2007 Championships, earning three gold medals along with a bronze. In 2013, Brazil once again hosted the World Judo Championships, this time placing fourth overall behind Cuba, despite surpassing Cuba in the total number of medals. In this event, Rafaela Silva made history by becoming the first Brazilian judoka to claim gold in a women's division.
