Hanshin Racecourse

|

Turf 1600m (Outer)

Key Takeaways

Crucial Indicator

A key predictor for the next year’s Classic races for fillies, identifying future champions.

Challenging Course

Hanshin’s 1600m outer turf demands comprehensive ability with its long straight and steep uphill finish.

Top Contender

Data analysis positions Arancarf as the strongest favorite due to exceptional potential and pedigree.

Race Pace

Anticipated average pace, likely setting up a dramatic contest of acceleration or a test of stamina in the straight.

1. The Two-Year-Old Filly Championship

The 77th Hanshin Juvenile Fillies (G1) is more than just a race; it’s the genesis of future legends. Held on December 14, 2025, it serves as a rigorous trial to select “future champion mares” who will define the next generation of Classic contenders.

This report meticulously analyzes 26 entrants, using over 15,000 words of data from training records, interviews, and pedigree charts to decipher the uncertainties inherent in two-year-old races and reveal the true potential of each filly.

2. Stage Analysis: Hanshin Turf 1600m

Known as one of Japan’s premier “ability-testing courses,” the Hanshin 1600m outer course is defined by its geometry. A 444m run to the third corner minimizes draw bias, often leading to a relaxed pace.

The true test is the finale: a 473.6m straight featuring a steep 1.8m uphill climb. This obstacle demands not just speed, but lactic acid tolerance and raw power from the hindquarters—a decisive factor for developing two-year-old fillies.

3. Detailed Analysis of Expected Participants

Arancarf (アランカール)

Top Favorite

Pedigree: Sire Epiphaneia x Dam Sinhala (Deep Impact). The “royal road” cross for Hanshin, combining stamina and explosive acceleration.

Performance: Remarkable final 3 furlongs in 33.3s in her last race. Jockey noted her acceleration was “completely different,” proving G1-caliber potential.

Training: Final workout clocked a final furlong of 11.0s, showing sharp acceleration. Mentally calm and physically prepared with no weaknesses.

Arbanne (アルバンヌ)

Pedigree: Sire Admire Mars x Dam Petit Folie. A blend of world-class speed and dam-side stamina, suited for tough tracks.

Performance: Showed intelligence and ability in the Safran Stakes. Victory at Nakayama suggests she will thrive on Hanshin’s long straight.

Training: Final furlong of 11.3s, easily pulling away from older horses. Her keenness has been corrected, indicating peak condition.

Sunbright (サンブライト)

Pedigree: Sire Lord Kanaloa x Dam sire Shamardal. A “powerhouse” pedigree that should excel on Hanshin’s steep hill.

Performance: Won her maiden despite jockey noting room for improvement, highlighting immense mental fortitude and raw talent.

Training: Shows “propulsive running,” and previous issues are resolving. Trending towards a peak performance.

Angelitas (アンヘリータス)

Lacks class at G1 level; tough race expected.

Inubovnoutagoe (イヌボウノウタゴエ)

Explosive European bloodline. Powerful stride is a weapon on the spacious course.

Wing Blue (ウィングブルー)

Strong front-runner, but stamina improvement is key for G1.

Gallaborg (ギャラボーグ)

High ability but difficult temperament. Rapid final furlong in training (11.2s).

Cosmo Red (コスモレッド)

Excellent response and rapid growth shown in training.

Shonan Charis (ショウナンカリス)

Highest instantaneous acceleration in the field. Challenge is sustained speed.

Sweet Happiness (スウィートハピネス)

Good mile suitability; gradually extends. Needs more to challenge top tier.

Stunning Lady (スタニングレディ)

Remarkable fighting spirit and mental strength. High completion rate.

Star Anise (スターアニス)

Pure speed bloodline; 1600m may be her limit. Stamina is a concern.

Taisei Fressa (タイセイフレッサ)

Strong dirt pedigree; tough race expected on turf G1.

Taisei Borg (タイセイボーグ)

Potent closing speed but slow starter. Chance if she breaks cleanly.

Noir Venus (ノアールビーナス)

Skillful racer. Interesting contender if she draws an inside gate.

Birthday Flight (バースデイフライト)

Hidden ability but suffers from gate issues and nervousness.

His Masterpiece (ヒズマスターピース)

Tenacious if allowed to set her own pace. Resisting pressure is key.

From Raven (フロムレイブン)

Sprint champion pedigree. Extending the distance is a concern.

White Orchid (ホワイトオーキッド)

Excellent acceleration and racing sense. A potential dark horse.

Marga (マルガ)

Well-bred but temperamental. Dangerous contender if she can settle.

Margot Love Me (マーゴットラヴミー)

Tremendous speed, but ability to handle a contested pace is a question.

Mitsukane Venera (ミツカネベネラ)

Patient racer with sharp leg action. Solid choice for core bets.

Maple Happy (メイプルハッピー)

Stable condition, handles heavy ground but may lack top speed.

Lasting Snow (ラスティングスノー)

Strong when she gains speed. A potential pace-setter.

Lady Goal (レディーゴール)

Appears outmatched; training times are not notable.

Rose Charis (ローズカリス)

High dirt suitability; speed on turf is a concern.
