Four Japanese horses aimed at The Championships during the Sydney autumn racing carnival have arrived in Australia.

To The World, Tosen Stardom, Real Impact and World Ace landed in Sydney on Wednesday night before being transported to the newly approved quarantine facility at Canterbury racecourse.

The quartet were reported to have handled the trip well and will soon do light exercise.

World Ace, a Group Two winner over 1600m in Japan, is equal favourite for the $3 million Doncaster Mile.

To The World, a $6 chance for the Queen Elizabeth Stakes, is a dual Group One placegetter and finished runner up in the Arima Kinen at his most recent start in December.

Two internationally trained horses competed at the inaugural The Championships last year and both won Group One races.

Japanese mare Hana's Goal claimed the All Aged Stakes while Irish sprinter-miler Gordon Lord Byron took out the George Ryder Stakes.
