Ozeki Takakeisho, Asanoyama and Shodai made winning starts Sunday at the November Grand Sumo Tournament.
With Mongolian-born yokozuna Hakuho and Kakuryu out through injury, the ozeki trio came under the spotlight on the opening day at Tokyo's Ryogoku Kokugikan.
All three are bidding for their second Emperor's Cup at the 15-day meet, which has been moved from its normal home in Fukuoka to limit travel during the coronavirus pandemic.
