Terunofuji continued to be the class of the Summer Grand Sumo Tournament, improving to 6-0 with a one-sided win on Friday to retain the sole lead after six days at Tokyo's Ryogoku Kokugikan.
With the spotlight on him following his historic re-promotion to ozeki, Terunofuji seized his favored left-hand overarm hold from the jump and forced out No. 5 Hoshoryu (2-4) with little trouble.
The 29-year-old Mongolian is fighting as an ozeki for the first time since September 2017, when knee injuries began taking their toll and eventually dropped him into the sport's second-lowest division.
