Sounds like Kokushikan. They still have a club and are slowely building their reputation up again. Uchimura Ryoichi attended it. I was/am interested in going there and asked my sensei about it. Essentially, there was a freshman who's father was a very famous sensei. So the sempai singled him out and were especially mean to him. One day, they ganged up on him, beat him, and stuffed him upside down into a folded mat where he suffocated. He was a very nice kid and the father's oldest son. That's the story.
