The Rugby World Cup host nation for both men and women is selected by World Rugby at a meeting six years before each tournament. Each of the Men's Rugby World Cups from 1987 to 2015 were hosted by countries that are considered the traditional powers in World Rugby. The first non Rugby Championship or Six Nations country to host a Rugby World Cup was Japan in 2019, after failed bids for the 2011 (awarded to New Zealand) and 2015 (awarded to England) tournaments. The women's version of the Rugby World Cup, which is known as the Women's Rugby World Cup, was first held in 1991, alternating with even-numbered non-leap years from 1994 to 2014 before switching to odd-numbered years from 2017 onwards.
