In japan, many still refer BJJ as Brazirian no Judo [Brazil's judo].
I asked a japanese Judo teacher and he said that "many japanese don't see BJJ as an sd art like jujutsu, it's more like a sport like Judo that's why many call it Brazilian Judo"..
But I think, that after the success of the Gracie's the Judo fedaration wants a part in it by saying "The Gracie's learnt Judo from Maeda". But we also know that Maeda was sent to S.America by Kano due to the fact he was radically changing Judo focus of nage-waza to ne-waza.
that's my 100 yen
