Deep Brillante will run in the King George VI and Queen Elizabeth Stakes at Ascot Racecourse on Saturday with no excuses, according to his trainer.
The Japanese raider was the only three year old declared at Thursday's final stage for the high-class middle distance contest.
The Japanese Derby winner arrived in England on July 6 and has settled in at Clive Brittain's yard in Newmarket well.
Trained by Yoshito Yahagi, Deep Brillante receives 12lbs from eight rivals, while Danedream, the filly who won the Prix de l'Arc de Triomphe last season, concedes 9lbs.
"There was no problem in the shipment of this horse from Japan," the trainer said. "As he is the only three year old in the race, the weight for age difference is a big advantage to him.
"We came over to improve the perception of Japanese horse racing. We are trying him at this level because he is the best horse I have ever trained."
Of the 10 horses that remained in the Group 1 contest at Thursday's final stage, only Robin Hood, a pacemaker, and Brown Panther have not registered a win at the highest level.
Nathaniel is set to defend his crown under William Buick, and John Gosden also will saddle Masked Marvel, who beat Brown Panther in the St Leger last season.
Australian form is represented by Dunaden, the Melbourne Cup winner.
Others to be declared include St Nicholas Abbey, the Dubai Sheema Classic runner-up and Coronation Cup winner, and Sea Moon, the Hardwicke Stakes victor at Royal Ascot.
Reliable Man, last season's French Derby winner, completes the line-up.
