The world's highest ranked horse, A Shin Hikari, bids to become the first Japanese-trained Royal Ascot winner when he runs in the Prince of Wales's Stakes.

The five-year-old has racked up a string of wins in his homeland, but it was his all-the-way victory in December's Hong Kong Cup that really propelled him to a wider audience.

He made a devastating start to his European stint with a 10-length victory in the Prix d'Ispahan at Chantilly last month and is odds-on to follow up in the feature event on day two of the showpiece Ascot meeting on Wednesday (Thursday AEST).

Aidan O'Brien has saddled two previous winners of the 10-furlong (2000m) race - Duke Of Marmalade (2008) and So You Think (2012) - and sends top-class filly Found into battle this time.

Last year's Breeders' Cup Turf winner has had to make do with the runner-up spot at her past two starts in the Tattersalls Gold Cup at the Curragh and the Coronation Cup at Epsom.

Clive Cox expects the soft conditions to suit My Dream Boat, who was fifth behind A Shin Hikari at Chantilly.

"He will be very much at home in the conditions and we're looking forward to running him," Cox said.

"I'm full of admiration for the Japanese horse who was pretty mind-blowing in Chantilly, but our horse is in great form.

"I couldn't be happier with his well-being and if he can put in the same sort of performance he did at Sandown, he should give a good account of himself."
