"With the identity of 12 teams already known, it will be of huge interest to players and fans to know which sides will be in their pool for what will be a game-changing tournament in Japan.
"While the draw is closer to the start of the tournament this time around compared to the previous Rugby World Cup, it is necessary to conduct it well in advance for logistical reasons and to allow for an effective ticketing programme to be implemented."
Former England and British and Irish Lions star Beaumont was unanimously elected as World Rugby's new chairman as expected in the governing body's board meeting in Dublin on Wednesday.
Former Argentina scrum-half Agustin Pichot was elected vice-chairman, with both new appointments standing unopposed.
Rugby Football Union and Six Nations chairman Beaumont was World Rugby vice-chairman from 2007 to 2012, and has also served on World Rugby's executive committee and the Rugby World Cup board.
Beaumont and Pichot's elevation came as World Rugby confirmed the pool draw for World Cup 2019 is now slated for May next year - eight months closer to the tournament than the draw for 2015.
England, Wales and Australia all fell into the toughest pool of World Cup history for the 2015 tournament, when the draw was made in December 2012.
Wales' slip to ninth in the world rankings after the November 2012 Tests allowed them to fall into the same pool as England and Australia.
Rugby's leading nations believe the later the draw is held the more accurately it can reflect the standard of the competing countries by the time the contest comes about.
