Currently the only yokozuna is Terunofuji.

Eventually, some new yokozuna will be promoted.  The promotion of yokozuna is guarded by a set of somewhat consistent rules and it will be known in advance to some degree.

Add the month and year of the tournament you think the new yokozuna will debut.

Make your answer like: "September 2024" or "November 2025"

You can pick any year you wish, as long as it is in the future.

If the new yokozuna is listed on the banzuke as Yokozuna but does not participate, that still counts as Yes for that tournament.  It should resolve as soon as the banzuke is released.
