Terunofuji put on a sumo clinic to see off Sadanoumi and retain his share of the lead at 6-0 in his ozeki debut at the Nagoya Grand Sumo on Friday.
Terunofuji got in a quick smack to Sadanoumi's head at the charge and gained control by getting a firm, two-handed grip on the back of the top-ranked maegashira's belt.
The 23-year-old Mongolian then lifted Sadanoumi (2-4) off his feet and finished the job with a sukuinage (beltless arm throw) to keep him on track for a second consecutive Emperor's Cup.
