His oyakata – ex-yokozuna Asahifuji – also received a red rope for his 60th birthday, when it's customary for yokozuna to make their last dohyo-iri.
60 years is the full length of the Chinese zodiac cycle (5 elements and 12 animals), so on the 60th birthday in Japan you celebrate kanreki, which is in a way understood as rebirth – being born into next cycle of life. Customarily red colour is worn on this day, so the rope is also red instead of white.
