Ozeki Harumafuji officially became the 70th yokozuna in sumo history on Wednesday after the Japan Sumo Association finalized the promotion of the Mongolian wrestler during its executive committee meeting.

JSA executives rubber-stamped the promotion of Harumafuji based on the recommendation unanimously made Monday by members of the Yokozuna Deliberation Council, an advisory body to the association, after the 28-year-old wrestler secured back-to-back tournament titles with his victory at the Autumn Grand Sumo Tournament last week at Ryogoku Kokugikan.

"I accept this humbly," Harumafuji said. "With the awareness of what it means to be a yokozuna, I will devote my body and soul to the way of sumo. Because I am who I am, all I can do is give my all in my own way. I want to get the most out of each and every day.
