Converted into the race that effectively crowns Japan’s Horse of the Year, the Japan Cup has revealed remarkably consistent patterns over the past decade. The favorites hold their ground, runners aged five or younger dominate, inside draws carry measurable weight, and the major players typically arrive via the Kyoto Daishoten, the Shuka Sho, or the autumn Tenno Sho. Data points that help frame the present—and anticipate the true protagonists—of Japan’s great international showpiece

The Japan Cup is not only one of the richest and most prestigious races on the global calendar—it is, in many cases, the contest that ultimately settles who the true generational leader of Japanese racing is. It’s no coincidence that Do Deuce (Heart’s Cry), the 2024 winner, was named Horse of the Year in the same season, just as Equinox (Kitasan Black), who captured the 2023 edition while sealing an extraordinary streak of six consecutive Group 1 victories—including international ones—went on to secure that same honor.
With that context, examining the race’s statistical trends over the last decade reveals some compelling patterns when it comes to identifying the type of horses that tend to rise to the occasion over Tokyo’s 2400 meters.
Favoritism Matters—A Lot
The numbers are emphatic: over the last 10 years, 26 of the 30 horses that finished in the Top 3 entered the race as the fifth choice or shorter in the betting. On the opposite end, every runner sent out at odds of 11–1 or higher finished outside the trifecta.
An even more striking figure: horses that went off as the ninth or tenth betting choice have not managed a single Top 3 finish since 2015.
The conclusion is straightforward: in the Japan Cup, the market tends to be right, and the main contenders generally show up.
Age: Five Is the Upper Limit
Another strong pattern revolves around age. In the last decade, all 30 horses that finished in the Top 3 were five years old or younger. Not a single older horse—six or up—has managed to hit the board during that span.
In a racing culture where Japan often keeps its top stars in training longer, this trend underscores that the Japan Cup remains a domain dominated by horses in peak athletic form and full physical maturity.
Inside Posts Carry Real Weight
Post position is another recurring theme. Over the past 10 editions, 19 of the 30 horses that finished in the Top 3 broke from gates 1 through 3.
The data reinforces the long-held notion that the inside draw offers a measurable advantage on Tokyo’s mile-and-a-half layout, especially in a race run at a selective tempo and featuring the highest-quality fields in the country.
Winning Last Out Is a Major Signal
A horse’s previous performance also plays a significant role. Of the 30 runners to finish in the Top 3 in the last decade, 14 arrived off a victory, and that group posted an impressive 37.8% strike rate in terms of hitting the board.
In other words: coming into the Japan Cup with a fresh win in hand is a very strong indicator of current form and competitive sharpness.
A Clear Pattern Among the Winners
Focusing solely on the last nine winners reveals an even sharper trend: every one of them prepped in one of three key races—the Kyoto Daishoten, the Shuka Sho, or the Tenno Sho (Autumn).
They also shared two decisive traits: they were five or younger, and they broke from posts 1 through 3. Youth, an ideal draw and the right prep path have formed a formula that consistently defines the recent winners of Japan’s great fall championship.
A Race That Crowns Champions
Beyond the international prestige attached to the Japan Cup, the data makes clear why certain profiles repeatedly come to the fore.
Strong betting support, youth, advantageous inside posts and preparation through the right traditional stepping-stones—these are the ingredients that have shaped the race’s modern history.
And if the last decade has shown anything, it’s that winning the Japan Cup brings far more than a massive trophy. More and more, it is the victory that crowns the true king of Japanese racing.
