I love this list!! Just when I think I know something about Sumo, something new comes along. Someone please explain to me the term "Yokozuna-Ozeki". I know about Higashi-Yokozuna, Nishi-Yokozuna, Sei-Yokozuna, and Haridashi-Yokozuna, but never Yokozuna-Ozeki. I am looking for a full explanation, origin, purpose etc. Thanks!!!!!! Otakeyama
