Yokozuna Hakuho's incredible 43 championships, 15 perfect titles and numerous other records and achievements rightly see him often referred to as the greatest rikishi in the history of sumo.

Comparing eras is hard enough in sports that have only been around since the 1800s. Trying to do so in sumo, when its history stretches back a couple of millennia, is a fool's errand.

The best we can do is try and compare rikishi who were active in the last century or so.
