I add that in the current case, while many oyakatas might be also motivated by power, the push for doing something seems to come from public opinion (at least as represented by media and politics), including public calls for resignation from the sports ministry.  

Then again, in the - in our Western eyes much more serious - scandal a year ago, when a wrestler died from brutal treatment during training, the public got a glimpse for a different standard for oyakata behaviour behind closed doors...
