Rugby World Cup took place in Japan between 20 September and 2 November. It was the ninth edition and the first time the tournament has been held in Asia. Regional tournaments Major international competitions are the Six Nations Championship and The Rugby Championship, held in Europe and the Southern Hemisphere respectively. The Six Nations is an annual competition involving the European teams , , , , and . Each country plays the other five once. Following the first internationals between England and Scotland, Ireland and Wales began competing in the 1880s, forming the Home International Championships. France joined the tournament in the 1900s and in 1910 the term Five Nations first appeared. However, the Home Nations (England, Ireland, Scotland, and Wales) excluded France in 1931 amid a run of poor results, allegations of professionalism and concerns over on-field violence. France then rejoined in 1939–1940, though World War II halted proceedings for a further eight years. France has played in all the tournaments since WWII, the first of which was played in 1947. In 2000, Italy became the sixth nation in the contest and Rome's Stadio Olimpico has replaced Stadio Flaminio as the venue for their home games since 2013.

The Tri Nations was initially played on a home and away basis with the three nations playing each other twice. In 2006 a new system was introduced where each nation plays the others three times, though in 2007 and 2011 the teams played each other only twice, as both were World Cup years.

The competition has been officially rechristened as The Rugby Championship beginning with the 2012 edition. The competition reverted to the Tri Nations' original home-and-away format, but now involving four teams. In World Cup years, an abbreviated tournament is held in which each team
