Introduction: Ishikawa Yushun – The Pinnacle of Kanazawa’s Three-Year-Old Generation
The “Ishikawa Yushun” stands as the ultimate contest for Kanazawa Racecourse’s three-year-old generation. Formerly known affectionately as the “Ishikawa Derby,” its name was updated to reflect the national reform of dirt racing systems. Regardless of the name change, its prestige and status remain unwavering, solidifying its position as the most crucial race within the Kanazawa three-year-old classic series.
Watch the full video analysis here:
The Prestige of a Race Carrying the Derby Legacy
Contending for a hefty winner’s prize of 10 million yen, the finest three-year-old thoroughbreds clash over 2000 meters on the dirt track at Kanazawa Racecourse. This race is central to Kanazawa’s four-crown series, which begins with the “Kitanippon Shimbun Hai” trial and continues through the “MRO Kinsho” and “Thoroughbred Daishoten.” Victory here is an indispensable step to claiming the title of the strongest in the generation. For owners, trainers, and jockeys alike, this single race holds immense power to shape their careers.
Mastering the ‘Tight Turns and Multiple Corners’: A Deep Dive into Kanazawa’s 2000m Course
To accurately predict the Ishikawa Yushun, one must first understand the exceptionally unique course layout of Kanazawa Racecourse’s Dirt 2000m. The track, with a circumference of 1200m, sees horses navigate approximately one and a half laps, passing through no fewer than five corners.
The most distinctive feature is the incredibly short home straight, measuring a mere 236m – drastically shorter than major JRA (Japan Racing Association) tracks. This combination of a “short straight” and “five corners” defines the very nature of the race. Mere top speed is insufficient for victory. What is paramount is the finesse to navigate corners efficiently, the skill to secure a favorable position early, and the tactical acumen to make agile moves at critical moments. A single misstep in positioning or being wide on a corner makes recovery on the short straight virtually impossible. This course demands high-level strategy, keeping horses and riders on their toes from start to finish.
Unlocking Ishikawa Yushun 2025: Three Key Prediction Points from Past Trends
To conquer this complex race, we’ve thoroughly analyzed past race results. From this deep dive, three “ironclad rules” essential for betting consideration have emerged.
Point 1: Fillies Dominate Colts – Will History Repeat Itself This Year?
Delving into the history of the Ishikawa Yushun reveals an astonishing trend: fillies not only hold their own against colts but have, in fact, overwhelmingly dominated. In the past eight editions, an incredible five fillies have claimed victory:
- 2023: Shogama Tappuri
- 2022: Super Bantam
- 2020: Hakusan Amazones
- 2019: Longing Look
- 2017: Venus Arrow
To illustrate this trend more clearly, let’s examine the gender and jockey of the top three finishers over the past five years.
Ishikawa Yushun: Past 5 Years’ Results and Trends
Year Winner (Gender・Jockey) 2nd Place (Gender・Jockey) 3rd Place (Gender・Jockey) 2024 Namida No Kiss (Colt・Yuma Shibata) Ricca Marron (Filly・Hiroto Yoshihara) Lock City Boy (Colt・Hiromitsu Horiba) 2023 Shogama Tappuri (Filly・Hiroto Yoshihara) Diamond Line (Filly・Ryuya Nakajima) Nobu No Biscuits (Colt・Masayoshi Aoyagi) 2022 Super Bantam (Filly・Masayoshi Aoyagi) Star Fujisan (Colt・Hiroto Yoshihara) Style Yourself (Filly・Hiromichi Koga) 2021 Ivanhoe (Colt・Ryuya Nakajima) Billboard Queen (Filly・Hiroto Yoshihara) Sabuno Tamahime (Filly・Masayoshi Aoyagi) 2020 Hakusan Amazones (Filly・Hiroto Yoshihara) Fujiyama Bushi (Colt・Shirohisa Hirase) Kagano Homare (Colt・Taiga Kurihara)
As the table demonstrates, fillies consistently feature in the exacta or trifecta every year. This phenomenon is largely attributed to the 2kg weight allowance fillies receive (55.0 kg compared to colts’ 57.0 kg). While a 2kg difference might seem minor on a flat course, its impact is profound on Kanazawa’s 2000m, where horses navigate five corners, constantly decelerating and re-accelerating. This difference significantly affects stamina consumption. Fillies, lighter and more agile in maneuvering, often exhibit superior staying power in the race’s closing stages – a characteristic unique to this challenging course.
Among this year’s contenders, **Shogama Mattenashi**, **June No Look**, and **Viva Rojita** are the powerful fillies poised to benefit from this strong historical advantage. Their presence cannot be overlooked in your predictions.
Point 2: Bet on the ‘God of Kanazawa’! The Dominance of Jockey Hiroto Yoshihara
In regional horse racing, the presence of “course-savvy” jockeys, who intimately know a specific track, becomes a crucial factor in predictions. In the Ishikawa Yushun, **Jockey Hiroto Yoshihara** stands out as the prime example.
Throughout the race’s eight-year history, Yoshihara has achieved four victories (2017, 2018, 2020, 2023). Furthermore, he secured second place in both 2021 and 2024, meaning he has finished in the top two an astonishing six times in eight years! This incredible record speaks volumes about his expertise and affinity for this particular race. Additionally, **Jockey Masayoshi Aoyagi**, the victor in 2022, is another master who knows this course inside out.
This year, the “Yoshihara Magic” adds another intriguing layer to the predictions. Yoshihara is scheduled to ride **Viva Rojita**, a mare who finished a disappointing 9th in the trial race, the Kitanippon Shimbun Hai. Why would a master jockey, with such an intimate knowledge of this race, choose a horse that underperformed in its prep? Several possibilities come to mind:
- There was a clear reason for her poor performance in the previous race (e.g., interference, health issues).
- He believes she will truly shine with the distance extension from 1700m to 2000m.
- He is confident that his riding skill can maximize the horse’s potential, regardless of past form.
Regardless, the mere fact that Yoshihara is aboard **Viva Rojita** instantly elevates her from a long shot to a horse worthy of serious attention. Meanwhile, **June No Look**, the second favorite, will be ridden by Masayoshi Aoyagi. The combination of a strong contender and a master jockey who knows the course is undeniably formidable.
Point 3: The Kitanippon Shimbun Hai Finish – A Trap? Distance Extension and the Potential for Reversal
The “Kitanippon Shimbun Hai” (Dirt 1700m), the official trial race, is undoubtedly the most important prep race for predicting the Ishikawa Yushun. This year’s winner, **Kurino Charles**, displayed overwhelming strength, making him a clear favorite for the main event.
However, a significant trap lies within: the distance extends by 300m, from 1700m to 2000m, for the main race. This seemingly small difference often highlights stamina disparities and can lead to vastly different results compared to the trial. Here, each horse’s pedigree becomes crucial.
- Kurino Charles (Kitanippon Shimbun Hai 1st): His sire is Greater London, a son of Deep Impact, suggesting some stamina. However, his dam’s sire is Sakura Bakushin O, a renowned Japanese sprint king. This pedigree configuration raises a slight concern regarding his stamina over the tough 2000m distance with five corners.
- Shogama Mattenashi (Kitanippon Shimbun Hai 2nd): Her dam’s sire is **Heart’s Cry**. This name demands attention. Heart’s Cry is celebrated for imparting stamina and deep reserves to his progeny, notably siring Yamami Dance, who won the 2017 Ishikawa Derby. Her second-place finish in the 1700m trial, combined with a pedigree that clearly benefits from distance extension, strongly suggests the potential for an upset victory.
- Dannai (Kitanippon Shimbun Hai 10th): Despite a poor showing in the trial, his sire is Mickey Rocket, winner of the G1 Takarazuka Kinen (2200m). His grand-sire is King Kamehameha, known for his versatile stamina. Genetically, Dannai is clearly the type to excel over longer distances, making it premature to dismiss him based solely on his previous defeat.
Thus, blindly trusting the results of the Kitanippon Shimbun Hai is risky. The key to an upset lies in the horse’s suitability for distance extension, specifically the stamina embedded within its pedigree.
Ishikawa Yushun 2025: In-Depth Analysis of Key Contenders
Building upon these three crucial points, let’s conduct a thorough analysis of this year’s top contenders.
◎ Top Pick: Shogama Mattenashi
This horse aligns most perfectly with all three of our ironclad rules.
- Point 1 (Filly): Yes. She benefits from strong historical data.
- Point 2 (Jockey): Ridden by Taiga Kurihara, a top-ranking jockey in Kanazawa. While not the legendary Yoshihara, he is a highly capable and proven rider.
- Point 3 (Distance Aptitude): Her greatest strength. With Heart’s Cry as her dam’s sire, her pedigree offers immense confidence should the race demand stamina. Her strong second-place finish against tough competition in the 1700m trial demonstrates top-tier ability, and she is expected to improve further with the distance extension. Combining historical trends and pedigree, she is rated as the closest to the crown.
○ Contender: Kurino Charles
While his current form and momentum are arguably the best in the field, he faces challenges that need overcoming.
- Point 1 (Filly): No. Being a colt is a historical disadvantage according to our data.
- Point 2 (Jockey): Ridden by Ryuya Nakajima, a proven jockey who has won this race in 2019 and 2021, providing a strong partnership.
- Point 3 (Distance Aptitude): This is the main focus. While his performance in the trial was genuine, concerns about his stamina remain due to his dam’s pedigree. He possesses the power to lead from the front and hold on, but the possibility of his stride faltering in the final stretch should be considered.
▲ Dark Horse: Viva Rojita
Despite recent poor form, she possesses enough compelling attributes to be considered a major long-shot contender.
- Point 1 (Filly): Yes. She rides the trend of filly superiority.
- Point 2 (Jockey): Yes. The primary reason for rating this horse is the presence of master jockey Hiroto Yoshihara. Everything hinges on how he manages to orchestrate a comeback from her 9th place finish in the trial.
- Point 3 (Distance Aptitude): While her sire, Henny Hughes, leans towards speed, her dam’s sire, Coronado’s Quest, provides stamina. She possesses an unknown potential, but the key will be her ability to show a dramatic improvement from her last race. Truly, this is a horse to back based on “jockey” and “history” rather than recent form.
△ Place Bet: June No Look
A transfer from JRA, she possesses considerable underlying ability.
- Point 1 (Filly): Yes.
- Point 2 (Jockey): Yes. Ridden by Masayoshi Aoyagi, the 2022 winner, who will undoubtedly maximize her potential.
- Point 3 (Distance Aptitude): Her sire, Real Steel (by Deep Impact), is suited for middle to long distances, but her dam’s sire, Acclamation, has a strong speed influence, making her pedigree assessment similar to Kurino Charles. While her JRA-honed class is appealing, her adaptability to Kanazawa’s tricky course will be tested.
☆ Watch Out: Dannai & Talban
These two horses hold the potential for significant improvement with the distance extension.
- Dannai: Despite a disappointing 10th in the trial, his sire Mickey Rocket’s pedigree strongly suggests suitability for stamina-demanding races. As he is likely to be a long shot, he offers excellent value for exotic bets.
- Talban: Sired by Danon Ballard, another Deep Impact lineage horse. With pedigree suggesting improvement over distance from his 7th place in the trial, he is a strong candidate for inclusion in trifecta and superfecta tickets.
Conclusion and Outlook – Who Will Emerge as the True Champion from Our Three Key Points?
Path to the Final Conclusion
As our analysis has shown, the 2025 Ishikawa Yushun presents a fascinating dynamic. While **Kurino Charles** enters with overwhelming momentum after his trial victory, past data has consistently favored fillies and horses with strong stamina pedigrees.
The decisive factor in this race will undoubtedly be the distance extension from 1700m to 2000m. This 300m difference has the potential to overturn trial results and crown a new hero or heroine. Your betting strategy will likely diverge significantly: will you favor current “momentum,” or will you align with the inherent “data and pedigree” that defines the essence of this race?
