IRB Council revealed the host unions for Rugby World Cup 2015 and Rugby World Cup 2019 would be England and Japan respectively.
Visit Britain head of business visits and events Joss Croft said: "The IRB World Cup offers huge potential for Britain in terms of additional incremental business from corporate travel in the lead up to, during, and as a legacy of the competition."
"Media visits, sporting congresses and sponsor conventions and - during the competition itself - incentive travel and corporate hospitality, will all bring huge additional opportunities."
Mayor of London Boris Johnson said: "With the Women's Rugby World Cup in 2010, the men's tournament in 2015 is another feather in the cap for the sport and adds to London's outstanding calendar of international sporting events - from the 2012 Olympic and Paralympic Games to the ICC Twenty20 World Cup, and the NFL at Wembley to the Tour de France Grand Depart."
"London has some of the finest sporting venues in the world - Twickenham, of course, as well as Wembley and the Emirates Stadium. But from 2012 there will be another, excellent new venue, the Olympic Stadium. We will discuss the option of it providing another base with the RFU and work with them to ensure the 2015 Rugby World Cup is the best ever tournament."
Keith Prowse marketing manager Ted Walker said: "Corporate hospitality is predominantly spectator sport-related and rugby has had a loyal following for many years. Testament to this is the growing popularity of both domestic and international rugby at Twickenham. Subsequently, the move will foster a much-needed global reach - that is to say, inbound business tourism from participating countries."
England will also host the Rugby League World Cup in 2013.
Britain major sporting events in the pipeline:
- Ryder Cup in 2010
- 2012 Olympic and Paralympic Games
- Glasgow Commonwealth Games in 2014
