I see there were no Yokozuna back in 1992 at one stage on the banzuke but you confuse me. Surely the last time there were no Yokozuna competing(other than last year) was when Asashoryu went kyujo in 2006.
Yes sorry I meant back in the day as opposed to recently. Would it have been when Asashoryu was sole Yokozuna or have there been other tournaments since 2006 where no Yokozuna were competing?
