Full Field Bloodline & Aptitude Analysis

1

Gate 1

Yamanin Endymion

#1 | Male, 6yo | 55kg

Aptitude: Stamina-rich lineage (Satono Diamond x Special Week) with a 3×3 Sunday Silence cross. Excels in sustained speed, making him a contender in stamina-sapping races. Distance reduction is a question, but his toughness suits Nakayama.

Recommendation: Last race was affected by interference. Previous 2nd place at 14-1 odds shows ability. From the innermost gate, he could surprise by overtaking tiring horses.

2

Gate 1

Ok Birdy

#2 | Filly, 5yo | 54kg

Aptitude: Sire Sinister Minister is a king of Nakayama Dirt 1800m. The pedigree is an ideal combination of speed, stamina, and European toughness. Perfectly suited for this course.

Recommendation: Won her last race here by leading from the start. Inner gate and front-running style make her a major threat. Despite short rest, training is brisk. A strong dark horse.

3

Gate 2

Chuwa Chris Es

#3 | Male, 4yo | 56kg

Aptitude: Sire Le Vant Slew (Roberto lineage) passes on power and high aptitude for Nakayama. Dam sire South Vigorous adds speed, creating a perfect stamina-speed balance for a tenacious style.

Recommendation: Already proved his ability at this class with a 3rd place finish last time. Prefers right-handed courses like Nakayama. Strong contender for victory from his forward position.

4

Gate 2

Arare Tabashiru

#4 | Male, 5yo | 56kg

Aptitude: Sire’s stamina (Cape Blanco) and dam sire’s speed (Duran Dal) make him adept at sustained runs from mid-pack (“makuri”). Strong Northern Dancer crosses enhance toughness.

Recommendation: Won his last race with a powerful finish. Blinkers have improved concentration. If the pace is fast, his closing speed could be decisive. Excellent training condition.

5

Gate 3

Danny Dean

#5 | Male, 6yo | 54kg

Aptitude: Real Steel x Numerous pedigree balances power and speed, but temperament can be an issue.

Recommendation: Poor last race, but has potential if he runs smoothly. Risk of being boxed in from an inner gate is a concern.

6

Gate 3

Hustle Dunk

#6 | Gelding, 6yo | 55kg

Aptitude: Powerful 4×3 cross of A.P. Indy gives first-class propulsion and stamina, ideal for Nakayama.

Recommendation: First race after gelding. If temperament improves, he could be a surprise performer.

7

Gate 4

Easy On Me

#7 | Filly, 6yo | 53kg

Aptitude: Daiwa Major x Pyro combination provides forwardness, speed, and power for Nakayama’s uphill.

Recommendation: Sharp finish for 4th in her last race despite traffic. Light handicap (53kg) is a huge advantage. Versatile and expected to contend.

8

Gate 4

Framlingham

#8 | Gelding, 5yo | 54kg

Aptitude: Daiwa Major x French Deputy pedigree suits Nakayama Dirt 1800m well.

Recommendation: Recent form has been poor. Training is not noteworthy. Needs favorable race development to improve.

9

Gate 5

Ore De Ii No Ka

#9 | Male, 8yo | 54kg

Aptitude: South Vigorous x Daiwa Major pedigree focuses on speed and power.

Recommendation: An 8-year-old veteran. Recent performance suggests a decline, but light handicap could help.

10

Gate 5

Seventh Letter

#10 | Gelding, 7yo | 52kg

Aptitude: Copano Rickey x Narita Brian offers stamina and resilience.

Recommendation: Training with hurdles suggests limited flat ability. Ultra-light handicap is attractive, but significant improvement is unlikely.

11

Gate 6

Ho-o Barista

#11 | Male, 7yo | 57kg

Aptitude: Stamina from sire Joe Cappuccino, enhanced sustained speed from dam sire.

Recommendation: Improving after a long layoff. Heavy handicap (57kg) is a burden. Needs to move early.

12

Gate 6

Pixilation

#12 | Filly, 6yo | 55kg

Aptitude: Heart’s Cry lineage provides growth and stamina. Strong dirt aptitude from dam line. Flexible for turf and dirt.

Recommendation: Good form, finishing 2nd last race. Training is excellent. While right-handed courses are a concern, her ability could overcome it.

13

Gate 7

Greatest Song

#13 | Male, 4yo | 55kg

Aptitude: Mozu Ascot (Frankel line) brings speed, complemented by Heart’s Cry’s stamina. Excellent sustained speed.

Recommendation: Last race was poor but excusable. Has a chance to rebound. A smooth forward run could lead to a tenacious performance.

14

Gate 7

Suzuno Teresa

#14 | Filly, 7yo | 50kg

Aptitude: Ruler Ship and Timber Country lineage makes her one of the strongest in terms of pure stamina.

Recommendation: Huge 50kg handicap advantage, but recent form and age are major concerns.

15

Gate 8

Miraihenokagi

#15 | Male, 4yo | 56kg

Aptitude: Mozu Ascot’s speed and Fuji Kiseki’s agility create an excellent pedigree. Possesses all necessary elements for this course.

Recommendation: Unquestionable ability shown by 3rd place in his last race at this class. Well-rested and prepared. Outer gate is a significant advantage. Strong contender for victory.

16

Gate 8

River True

#16 | Filly, 6yo | 54kg

Aptitude: Red Falx x Victoire Pisa provides high dirt aptitude with a mix of speed and power.

Recommendation: A pace-dependent closer. The outermost gate benefits her style. If she can accelerate smoothly, she has a chance to place.
