An in-depth analysis…
The 2025 Keio Hai Nisai Stakes (GII) is a crucial race that foretells the future GI circuit. This article provides a thorough analysis based on the latest data, examining the chances and vulnerabilities of the overwhelming favorite, Diamond Knot, and the capabilities of contenders Red Stinger and Milt Best. Furthermore, we offer expert insights into promising dark horses with betting value, such as See Mi Hat Ku, who is expected to show dramatic improvement with first-time blinkers, to help you formulate your predictions for the Keio Hai Nisai Stakes.
The 61st Keio Hai Nisai Stakes (GII), one of the most important prep races for sprinters and milers, will be held at Tokyo Racecourse over 1400m on turf. This race is a key indicator for the future of the two-year-old division, with talented horses gathering on the Fuchu straight, potentially leading to the Asahi Hai Futurity Stakes (GI) and next spring’s classic races.
Races between inexperienced two-year-olds are often decided by factors beyond simple data. However, recent training conditions and stable comments strongly reflect each horse’s condition and strategy. In this article, we will thoroughly analyze the “prediction points” for conquering this challenging two-year-old graded stakes race from an expert’s perspective, based on the latest materials (entry list, training data, stable comments, and post-race interviews).
The core of formulating a prediction for this race lies in evaluating the top three favorites, who have garnered the most expert picks and lowest projected win odds. We will dissect their raw ability, recent condition, and potential risks revealed by the data from multiple angles.
With projected win odds of 2.4 and picks from four experts (◎○○◎), this horse is undeniably the top contender.
Finished 2nd in the Momiji Stakes (OP) at Kyoto over 1400m turf. Notably, despite the loss, he recorded the fastest final 3 furlongs (last 600m) of the field at 33.3 seconds. After the race, jockey Yuga Kawada commented, “I felt we could catch up, but the winner pulled away again. The opponent was just too strong,” candidly acknowledging the winner’s strength. Diamond Knot’s own performance can be highly rated.
A tight two-week interval between races is typically a concern for two-year-olds due to potential fatigue. However, the stable (trainer Yuichi Fukunaga) has given a vote of confidence, stating, “It’s a tight schedule, but there’s no damage, and he’s been brought along smoothly.” Backing this up, his final workout on November 5th (Ritto Training Center, uphill track) earned the highest praise: “Still in excellent form.” His coat is glossy, and he appears not just to be maintaining his condition but even improving. Successfully navigating this challenging schedule proves his high level of maturity and mental toughness.
Trainer Fukunaga expressed absolute confidence in his aptitude, saying, “Even before his debut, I thought he had a great turn of foot for shorter distances.” He also mentioned race strategy: “At 1400 meters, he can get a good position. This way, he won’t be at the mercy of the race pace.” In his last race, he lost despite a powerful 33.3-second final kick. Based on this result, it’s clear the stable intends to broaden his tactics from a “one-trick closer” to a more versatile style of “settling in a good position.” Being able to run a race that isn’t dependent on pace on Tokyo’s long straight is a massive advantage for a heavy favorite, and we can expect a strategy with a higher win probability, learned from the previous defeat.
With projected win odds of 7.6 and two expert picks (○○), he is the leading challenger.
Finished 2nd in a 1-win class race at Tokyo over 1400m turf, the same course and distance as this race. His final 3 furlongs time of 33.2 seconds was tied for the fastest in the field. Jockey Kazuo Yokoyama praised his performance, saying, “He’s a versatile horse, and he ran a good race today,” highly rating his ability to perform well when held back.
The “workout brief” for his final gallop on November 5th (Miho Training Center, woodchip course) seems modest: “Time was average, but he stretched out well.” However, a closer look at the “detailed analysis” reveals a different story: “Although he always looks good, his limbs moved well, and he was full of power. His concentration was also high,” and “His aura is impeccable.” These comments praise the quality of his movement beyond the stopwatch time. In expert analysis, the visually confirmed “quality” of movement should be valued more than mechanical times. The stable (trainer Daiki Yajima) also commented, “His concentration seems to have improved since his last race,” suggesting that his final preparation was perfect and more substantial than the time indicates.
Trainer Yajima highlighted his adaptable style: “He ran a good race from off the pace last time,” and “It was a performance that broadens his options for racing at Tokyo.” His versatility to handle any race style and his perfect condition are significant weapons on the graded stakes stage.
As his projected win odds of 8.0 suggest, he is highly regarded by the market for his potential, despite having few expert picks.
He won his debut race (Kyoto, 1400m turf). The performance symbolized his dual nature. Jockey Mirai Iwata clearly pointed out his temperament issues, “He was quite tense until the third corner,” but also acknowledged his high potential, “He responded well in the end.”
His final workout on November 5th (Ritto, uphill track) was nothing short of spectacular. As the brief “Effortless fast time” suggests, he recorded an exceptional 51.2 seconds for 4 furlongs on the uphill track under a simple canter. The “detailed analysis” also praised his ability: “High physical ability, easily clocks fast times.”
On the other hand, the stable (trainer Naoya Nakamura) has expressed a frank concern: “He gets tense easily, so we’ll see how he handles the long-distance transport,” indicating that the trip from Ritto to Tokyo Racecourse is key. This horse combines “overwhelming physical ability (51.2s uphill)” with “serious temperament risks (stable/jockey comments).” The stable’s strategy is summarized as, “He’s fast out of the gate, so I think he can get a position where he won’t get boxed in.” This implies that if he gets caught in the pack or has a bad start, there’s a high chance he could mentally break down. Therefore, his evaluation depends on his paddock demeanor on race day and the early pace, making him the highest-risk, highest-reward contender.
While the top favorites form a strong lineup, two-year-old races always hold the potential for the hierarchy to be upended by a small trigger. We pick out notable dark horses from the materials who show clear “factors for improvement.”
The entry list shows a “B” in the blinkers column, indicating this is the first time he will wear them in a race.
This equipment change has a clear purpose. The stable (trainer Ryo Terashima) has confirmed their effectiveness in training: “Wearing blinkers has helped him run with more focus.” As if to prove this, in his final workout on November 5th, he showed excellent movement against Smart Eye, an older, open-class horse, “tracking 0.9 seconds from the inside and finishing 0.1 seconds ahead at a full gallop.” The brief also rated him highly: “Looks even better than his last race.” A two-year-old outperforming an older open-class horse in training is a testament to his ability. If this performance boost is directly linked to improved “concentration” from the “blinkers,” it can be judged as a “clear step up from his last race.” He is the horse most likely to show dramatic improvement due to an equipment change.
As noted in his brief, “Always has a fast finish,” his sharp closing speed is his greatest weapon.
In his maiden win (Tokyo, 1400m turf), he unleashed a sharp kick with a final 3-furlong time of 33.6 seconds. Jockey C. Lemaire (replaced by Poucha this time) praised his course suitability and ability: “He showed a good turn of foot,” and “This 1400 meters is perfect for him.” On the other hand, the stable (assistant Ito) commented, “He can be a bit difficult to control, so at the jockey’s request from training, we’ve changed his bit to a ring bit.” The horse’s weakness is “maneuverability,” and they have taken a concrete step to overcome it by “changing the bit.” If this equipment change is successful and he can conserve energy without fighting the rider, the “good turn of foot” he showed last time could be even more explosive on the graded stakes stage.
He is drawing attention from experts, receiving a “▲” (third pick) from one analyst (CPU).
While many others are stepping up from maiden or 1-win class races, this horse already has experience finishing 6th in the GII Saudi Arabia Royal Cup (Tokyo, 1600m turf). Regarding that race, assistant Ryo Shimizu cited the distance as the reason for defeat: “I got the impression that 1600 meters was his limit, and from his racing style, 1400 meters is probably his best.” The fact that he fought well to finish 6th in a tough GII race while “outside his ideal distance” (jockey Genki Maruyama commented, “He held on until the last 150 meters”) is highly commendable. This time, he returns to the 1400m distance that the stable declares is his “best,” while leveraging his experience. This is a classic pattern for an expected “bounce-back” performance.

| 12 | Fukuchan Show | Light-footed action | Condition is good. Prefers firm turf (good track). |
| 13 | Feder Rotor | Maintaining physique | Condition is same as last race (no change). A true test. |
| 14 | Towa Ni | Light-footed action (power UP) | Wants to utilize the long straight. Was too keen last race. |
| 15 | Linen Tairin | Young but moves well | Back to turf, want to consciously save his kick. |
| 16 | Red Stinger | Aura is impeccable (*from detailed analysis) | More focused now. Versatile enough for a graded stakes. |
