No it was not. Schedule for the day has Takadagawa, who has graying hair and silver bling. Not sure where you got your info from but I just watched the replay of the bout and Takadagawa delivering hansoku decision.
You chose to grab part of my response to a post by another poster I was explaining to that person and mixed in with your post. He has expressed a desire to play a role. No guaranty he will as I also explained the director was sacked and a new opening and closing ceremony director was appointed. My point is if he is in either opening or closing no one knows but organisers and participants.
The original director of opening and closing ceremonies was replaced. No one knows, other than people involved, know who will be in the ceremonies. It is supposed to be secret. It is assumed because it is Japan that sumo will have some role and it may do.
