Had to be NHK. The media there has been trying to demoralize the people into being leftists but culture and group think has slowed it down to a crawl, they aren't anywhere near as bad as the west and the kids who buy into it are eventually beaten down by the societal standards and rules or be ostracized and labeled a "trouble maker" which can kill job opportunities and getting accepted into a good college.
THAT'S been a thing for a long time now, they're called emergency detention laws and all states have them. They're SUPPOSED to be there for things like bioterror (terrorists aren't going to consent to treatment or want to stay in a hospital) or for those special kind of stupid people who get something like Ebola or Smallpox and want to leave while being walking bio bombs able to to kill a ton of people.....Basically a Baker Act but for physical illnesses.
