A yokozuna debutant has never won the Spring Grand Sumo Tournament.

News photoAsashoryu will make his debut as yokozuna and be the heavy favorite to win the Emperor's Cup at the Spring Grand Tournament in Osaka, beginning Sunday.

That's all about to change if scrappy Mongolian Asashoryu has his say-so when the meet gets under way at the Osaka Prefectural Gymnasium on Sunday.
