Tomiki Aikido is often known as the black sheep of the aikido world due to it's focus on competition in training in some of it's branches of the family tree. Apparently there is another society out of Japan incorporating a rougher shiai model into their training. HaitenKai Aikido.
As with most of the styles obsessed with victory and control, the results get rough and a little unaiki in my opinion. But who am I to judge.
