The Fukushima native becomes the first new sekiwake in 86 years to claim the championship.
New ozeki Mitakeumi keeps pace along with sekiwake Wakatakakage and rank-and-filer Kotonowaka.
With his third career title, the sekiwake will be considered for promotion to ozeki.
At the halfway point, the new yokozuna is firmly in control and appears on his way to a 15-0 record.
Fellow yokozuna Hakuho was forced to pull out over COVID-19 protocols.
Despite the loss, Terunofuji almost certain to be promoted to sumo's highest rank.
