Wales, Australia, South Africa and other home nations should forget hosting the World Cup.
Firstly im all for Japan hosting the world cup as its about time the IRB thought outside the box.
For me the next 3 world cups should be held in Japan, South America, USA or Canada.
If Rugby is truly to develop into a worldwide sport then these 3 key areas need to tapped into.
Im sick and tired of the norm that Rugby Tournaments bring, look what Football did for USA when it hosted the World cup. Canada have always been a proud Rugby nation it may not be their national Sport but neither is Rugby in England, Scotland and Australia!
World Cups bring huge revenue, exposure and tv viewings. Countries like the above mentioned would benefit hugely from it.
