I can't decide if this was shot on a real JR train, or whether it is a studio set with significant rear projection displaying the *views* outside the train's window. What leans toward the studio set, besides the severity of the acts the chikans perform, is that the Yamanote Line would be making station stops every three minutes or so. There are no edits (which would have been the station stops and announcements), But either way, this is a superb train molester video which should probably be recommended to anyone wondering what the chikan genre is about.
