The decision by organiser SANZAAR to revert to a purely southern hemisphere Super Rugby competition was a major blow for Japan and those who champion the growth of the game, as the nation prepares to showcase its development as hosts of the World Cup.
Leitch, who hasn't featured for the Sunwolves this season due to commitments with the national team, believes this is a mistake and that exposure to higher levels of competition is the only way to grow the sport he loves.
"It feels like the strong teams play within themselves and won't let anyone else in," Leitch said.
