The five tournament hosts, as well as all quarter-finalists from the previous (1987) Rugby World Cup, automatically qualified for the final tournament.
In qualification for the 1991 Rugby World Cup, Asia and Oceania were combined. The qualifying round-robin tournament was played in Japan in April 1990. The top two teams (Western Samoa and Japan) qualified for the finals and were allocated to Pool 3 and Pool 2, respectively.

Three nations from the Americas competed in qualifying matches for the 1991 Rugby World Cup. Because the Americas region had three places at the 1991 Rugby World Cup, all three participating countries from the Americas—Argentina, Canada and the United States—qualified for the finals tournament, with the qualifying tournament deciding to which pool each team would be allocated at the finals.
