Ōnishiki trained under former "yokozuna" Hitachiyama Taniemon, joining his Dewanoumi stable. He was promoted to the top "makuuchi" division in January 1915. After finishing the May 1915 tournament with a 9–1 record at the "komusubi" rank, he was promoted to "ōzeki". He won his first "yūshō" or championship with a perfect 10–0 record in the January 1917 tournament and was promoted to "yokozuna".
