Banzuke: rank recalculated every single tournament
Sumo's ranking list is redrawn after each of the six annual tournaments. A wrestler's next rank depends mainly on whether he achieved kachi-koshi (a majority of wins, eight of fifteen for top divisions) or make-koshi (a majority of losses), so status is continuously re-earned rather than held. Asymmetric protections at the top show how a meritocracy handles its elite: an ozeki is demoted only after consecutive losing records, and a yokozuna cannot be demoted at all and is expected to retire instead.
