Why Ippei Watanabe ranks #206 in Swimming

Ippei Watanabe ranks 206th among Swimming athletes on GOAT Rank and 2030th of 4013 across every sport in the index. The published GOAT Score of 78.8 is the weighted result of five verified category scores: Dominance 74, Peak 90, Longevity 72, Honours 78, Statistics 82. Those categories are normalised against the full Swimming reference universe of 289 records, not a shortlist, so the position reflects the whole sport rather than a handful of famous names.

The record covers 2014–present with 10 documented competitive seasons. The strongest single season in that series is 2017, which sets the Peak component at 90. Peak is the defining strength of the profile at 90 out of 100, and it carries 20% of the final score. The underlying career record includes world records 1, world championship medals 1, asian games golds 1, japanese titles 5.

Immediately ahead sits Angie Bainbridge on 78.9, a gap of 0.1 points. Directly behind is Penny Oleksiak on 78.7. The position moves whenever the verified record moves: new titles, new seasons or a corrected source all feed straight back into the same formula, and every change is dated on this profile.
