| World PORIZ ratings after
9th World Sumó Championships |
| WARNING: For women please only take the ratings as an indication of strength. While in the |
| case of men, the ratings closely model their skills on the dohyó, with women the low number |
| of matches makes the ratings statistically unreliable. As each woman gets above 20 |
| matches, the ratings will converge towards their real values. |
