There is a ranking system in professional sumo. The title of the top ranker is Yokozunaļ¼ęØŖē¶±ļ¼. When Ozeki (å¤§é¢, title of the second ranker) ranked wrestler won in the last 2 tournaments, he can be promoted to the Yokozuna. Conversely, Yokozuna who regretted his achievement in the last 2 tournament, he is forced to retire.
Yokozuna is not limited to one person, sometimes there are several yokozuna at one time. In Kyushu tournament of November 2017, four people, Hakuhouļ¼ē½éµ¬ļ¼, Harumafujiļ¼ę„é¦¬åÆå£«ļ¼, Kakuryuļ¼é¶“ē«ļ¼ and Kisenosatoļ¼ēØå¢ć®éļ¼ were the yokozuna.
Also, high dignity is required for the Yokozuna. Therefore, if the YokozunaĀ causes a scandal he will be forced to retire, even if his grades are good.Ā Harumafuji retired after this year’s Kyushu tournament, because he caused a problem hurting the young wrestler during drinking.
