Terunofuji Haruo, is a Mongolian-Japanese professional sumo wrestler. Wrestling for the Isegahama stable, he entered professional sumo in January 2011 and took the second division jūryō championship in his debut as a sekitori in September 2013. He took the top makuuchi division championship in May 2015, only 25 tournaments after his professional debut, which is the fourth-fastest behind Asashōryū and Takanohana's 23 tournaments and Takerufuji's 9 tournaments. This earned him promotion to sumo's second-highest rank of ōzeki.
Japan's sumo grand champion, Terunofuji, took part in an annual sumo ritual on Tuesday to officially kick off the wrestling season.
