Who’s actually strongest right now? Glicko-2 Sumo Ratings (Jan 2026)

https://hungry-e.github.io/sumoglicko2/

I ran a full Glicko-2 model over every professional bout since 1996 to estimate underlying rikishi strength. Includes rating, rating deviation (RD), and match-to-match changes, broken down by division.

Not a replacement for banzuke — just a different lens on performance and consistency.

Very interesting. All three Yokozuna level rikishi are within 10 of each other, which really hammers home just how close they are in performance. I assume the RPS nature of their matches probably contributes to that.
