Trainer Comments and Post-Trackwork Weights: Key Insights
- Croix du Nord (Gate 1, Horse No. 2): The Derby winner drew the innermost gate, considered ideal. Trainer Takashi Saito commented on the advantage of a “race with no wasted effort.” However, questions linger about his condition returning from the Prix de l’Arc de Triomphe. His post-trackwork weight is 514kg (previous overseas run).
- Masquerade Ball (Gate 7, Horse No. 15): This three-year-old colt dominated the Tenno Sho (Autumn) with a record-breaking final furlong of 32.3 seconds. Jockey C. Lemaire rides. While Lemaire expressed a preference for “a slightly inner gate,” confidence in his ability to unleash a powerful late surge from an outside draw remains high. His post-trackwork weight is 476kg (a +6kg increase from his previous run).
- Justin Palace (Gate 1, Horse No. 1): Assistant Trainer Yamamoto noted, “It’s an interesting gate depending on the start; if he breaks well, it’s good.” The team emphasized the horse’s improvement since his last race and his suitability for Tokyo.
- Carandagan (Gate 4, Horse No. 8): The reigning European Horse of the Year’s connections stated, “He excels on fast ground and left-handed tracks.” Having secured the bonus incentive (high prize money bonus), the stable’s serious intent is clear. His post-trackwork weight is 450kg (previous overseas run).
- Tastiera (Gate 8, Horse No. 18): Drawn in the widest gate, Trainer Hori emphasized, “He’s getting closer to his best form; he can show his full potential.” However, many views suggest “the outside gate will be tough,” predicting a challenging race for last year’s Derby winner.
Anticipated Odds and Jockey Lemaire’s “Confidence”
In the pre-pre-race odds (as of Friday), Masquerade Ball, ridden by C. Lemaire, emerged as the 2.5-1 favorite. Jockey Lemaire, who boasts an exceptional win and place rate at this track, expressed profound confidence in his mount, stating, “I am confident we can win” and that “the Tenno Sho (Autumn) was a good trial for the Japan Cup.” He further identified Carandagan as “the biggest rival,” showing greater caution towards the European challenger than domestic contenders, sparking excitement among fans who are already banking on Lemaire’s renowned judgment.
Conversely, the European powerhouse Carandagan, priced at 7.9-1, has drawn fervent support with comments like “severely underestimated” and “excellent value at those odds from a perfect draw.” Attention is now fixated on the final shifts in market popularity. Derby winner Croix du Nord, despite a favorable draw, saw his odds drift to 5.8-1, possibly due to lingering concerns about his post-Arc de Triomphe condition.

Heated Debate Over Post Positions and Key Contender Assessments
Data consistently shows a strong advantage for inner draws over the Tokyo 2400m turf course, with gates 1-2 accounting for 6 wins in the last 10 years. As such, Croix du Nord in Gate 1, Horse No. 2, has been a central topic, deemed an “overly perfect draw.” Yet, persistent doubts remain among some, citing “fatigue from the Arc de Triomphe” and speculation about “intentions for an Arima Kinen run,” leading to divided opinions on his true chances.
In stark contrast, the outermost Gate 8 clusters three notable contenders: Shin Emperor, Do Deuce, and Tastiera. For last year’s Derby winner, Tastiera, specifically, the widest draw (Gate 18) is widely seen as a significant disadvantage that will severely hinder his ability to unleash his full potential, predicting a very tough race.
Derby winner Danon Decile (Gate 7, Horse No. 14), while praised by some who claim “Jockey Tosaki believes this is by far the strongest horse he’s ever ridden,” faces concerns due to Jockey Tosaki’s track record over Tokyo 2400m GⅠ races (0 wins, 7 places, 0 shows, 27 unplaced efforts).
Editor’s Focus: The Specter of a Fast-Paced Race
This year’s Japan Cup is widely anticipated to hinge on the actions of the front-running and prominent horses. Entrants like Sunrise Earth (K. Ikezoe) in Gate 3, Horse No. 5, and Ho O Biscuits (Y. Iwata) in Gate 3, Horse No. 6, who are likely to aggressively go to the front, have drawn advantageous inner positions.
Discussions are vigorous regarding the potential pace, with questions like “Will the pace be relentless without slowing?” and “A dead-slow pace would be unexciting.” If Sunrise Earth were to set a challenging pace, reminiscent of Kiseki’s famous front-running display, it could provoke early moves from rivals and create a highly favorable scenario for horses with powerful closing bursts, such as Masquerade Ball and Carandagan. With several key contenders drawn wide, all eyes will be on the jockeys’ tactics and who will dare to dictate the flow of the race.
