Japan looked every penny of his 1,300,000gns fee that John Magnier paid for him two years ago, recording his first victory of the season.
That tells half the story though, as after his returning fourth in the Dante at York to brush the cobwebs away, he finished a very narrow third in the Derby at Epsom, just over half-a-length down on winning stablemate Anthony Van Dyck.
Made up a magnificent amount of ground that day, and seemed to have fully matured into a top colt in the preliminaries of his Royal task in the King Edward VII Stakes.
Ridden in similar fashion by jockey Ryan Moore, he was kept wide and motored up the straight to win in the style of a very good horse.
Being a three-year-old the obvious targets would feature either the English or Irish St Leger, but he looks that good he could jump the gun and end up fighting out the King George back at Ascot in a month's time.
