If the association -- tight or light -- with yakuza is not affecting the sport as a sport, who cares? Yakuza are a police problem, not something that a sports assoc should have to turn themselves inside out for. We know that yakuza are involved in all sorts of industries. Are they closed down? Is all construction at a standstill? Are movies still being made? Are banks still open? This is just madness! If the yakuza are causing bouts to be thrown, step on them. Otherwise, let's get on with ozumo!
