TOKYO, Japan — Sumo is facing a potential chasm at the top of the ancient sport for the first time in over 30 years after the only yokozuna, Terunofuji, announced his retirement on Friday.
The Mongolian-born 33-year-old has been the only top-ranked sumo for more than three years, and only 73 wrestlers have reached his level in the history of the centuries-old sport.
