If we’re talking about success, the biggest sumo wrestler of all time would be one of these three:
- Tameemon “Raiden” Torokichi, who had a 254-10 win-loss record in the 21 years from 1794 to 1815.
- Sadji “Futahayama” Akiyoshi, who had 69 consecutive wins in the 1930s
- Koki “Taiho” Naya, who won the Emperor’s Cup 32 times before retiring in 1971.
However, if you’re talking about physical size, then the hands-down winner would be Hawaiian-born Chad “Akebono” Rowan.
The first non-Japanese to be promoted to the rank of yokozuna (“grand champion”), Rowan is 6’8″ tall and 501 pounds, head, shoulders, and belly above his competitors.
