The CEO of Rugby Australia on Monday warned organizers of this year's World Cup to be prepared to deal with spectators that can be more a little more exuberant than the typical Japanese fan.

Speaking with a group of Japanese media outlets at Rugby Australia headquarters in Sydney, Raelene Castle said Japanese are known for being orderly, lining up nicely and being calm and patient.

"That is not true of international rugby fans who are coming from all around the world," she warned.
