Are they like the same thing except bjj is rougher? What are their differences.

judo focus's more on throws and then ties in the grappling. i believe it was made to fill ju jitsu. (not bjj)

I don't think I'd agree that bjj is rougher - they are both very intense. as for differences, it's mainly the focus - judo mainly focuses on throwing, however, it's not uncommon to find expaonents who love groundwork - my coach is one of them. In competition, however, groundwork is limited in judo, so you have to work fast - you are only allowed 10 seconds on the ground, unless progress is being made in a pin or towards a submission - once progress stops, they will stand you back up.

 

another difference is the rules - leg locks aren't allowed in judo, and scoring is different, obviously.

 

Are you looking for any specific things that may be different?

BJJ = Basically Just Judo.

 

Just joking. However they are very similar. The only differene techniques wise is that BJJers focus on the ground and Judoka focus on standing.
