Context: Tournaments are organised by Rugby World Cup Ltd (RWCL), which is itself owned by World Rugby. The selection of host is decided by a vote of World Rugby Council members.The voting procedure is managed by a team of independent auditors, and the voting kept secret. The host nation is generally selected five or six years before the competition.
The tournament has been hosted by multiple nations. For example, the 1987 tournament was co-hosted by Australia and New Zealand. World Rugby requires that the hosts must have a venue with a capacity of at least 60,000 spectators for the final. Host nations sometimes construct or upgrade stadia in preparation for the World Cup, such as Millennium Stadium – purpose built for the 1999 tournament – and Eden Park, upgraded for 2011. The first country outside of the traditional rugby nations of SANZAAR or the Six Nations to be awarded the hosting rights was 2019 host Japan. France will host the 2023 tournament. The next tournament to be hosted by a nation outside the traditional nations will be the 2031 tournament in the United States.
