It is. There is 67 throws in Kodokan Judo. To win a match in a Judo tournament you must score a Ippon or point in english. If your throw was off or they land on their side you may get a half point. You can also score points on the ground by like what techniques you use. The other way to win a Judo tournament besides ippon is making them sub on the ground. Which is scored as a Ippon. The refs don't give you long on the ground and work for position like in a bjj tournament. If you don't have anything or aren't working on a hold with in 5 to 8 secs after being on the ground they stand you back up, and you throw again. In Judo you can use pins, arms bars and chokes. You aren't allowed to use leg locks. Judo by far is my favorite style.
