Americans arrive for Japan Cup


All six of America's challengers in next weekend's Japan Cup and Japan Cup Dirt have arrived safely in Tokyo.

The two most prominent among them, Johar, the Breeders' Cup Turf winner, and Sarafan, last year's Japan Cup runner-up, arrived at Narita International Airport on Thursday morning in good order along with Denon. Slew Valley arrived on a separate flight from New York, while Japan Cup Dirt hopefuls Fleetstreet Dancer and Outta Here touched down together on Wednesday.

"The flight took 16 hours from San Francisco via Anchorage," said Sarafan's exercise rider, Robert Guest. "The horse is fine.

"We'll just be doing our usual work" during the at the five-day quarantine period, "and probably give him a fast work once we move to Tokyo Racecourse."

Trainer Richard Mandella will arrive in Japan on Tuesday, by which time his Turf dead-heater Johar will have arrived at Tokyo Racecourse from the Shiroi quarantine facility.

"I might give him a little half-mile breeze a few days before the race," said Mandella.

The $2.1 million Japan Cup Dirt will be run Saturday, with the $4.3 million Japan Cup set for the following day.
