The birth of the rank of "yokozuna" is unclear, and there are two competing legends. According to one, a 9th-century wrestler named Hajikami tied a "shimenawa" around his waist as a handicap and dared any to touch it, creating sumo as it is now known in the process. According to the other, legendary wrestler Akashi Shiganosuke tied the "shimenawa" around his waist in 1630 as a sign of respect when visiting the Emperor, and was posthumously awarded the title for the first time. There is little supporting evidence for either theory—in fact, it is not even certain that Akashi actually existed—but it is known that by November 1789, "yokozuna" starting from the fourth "yokozuna" Tanikaze Kajinosuke and the fifth "yokozuna" Onogawa Kisaburō were depicted in ukiyo-e prints as wearing the "shimenawa". These two wrestlers were both awarded "yokozuna" licences by the prominent Yoshida family.
