An in-depth analysis of the 1200m dirt race using AI predictions and expert data.
December 10, 2025 ◆ Final Race
The Izumo-ryu Sprint, the final race at Funabashi on Dec 10, 2025, is a crucial battleground for the Minami Kanto sprint circuit’s future stars. This report provides a comprehensive breakdown, leveraging advanced AI models, training data, and pedigree analysis for all 11 contenders. The spotlight is on the clash between the explosive 3-year-old, Joyful Rock, and a field of seasoned veterans.
Funabashi’s unique “spiral curve” design—gentle on entry, tight on exit—is a kingmaker. It allows front-runners to maintain blistering speed, while also creating openings for closers on the outside as the field fans out post-turn.
The current “Good” condition, combined with dry winter air, creates a power-sapping track. This favors horses with raw strength and stamina. Bloodlines like Henny Hughes and South Vigorous, known for producing powerful American-style sprinters, are at a distinct advantage.

Absolute Favorite
The undisputed star. A previous time of 1:12.5 would dominate even the B1 class. This 3-year-old phenom blends speed from sire Mr. Melody with stamina from dam’s sire Stay Gold, creating a powerhouse with no discernible weaknesses. Training reports are flawless.
Top Contender
Finished second to Joyful Rock last time out. Now in its second race at this distance and drawing the coveted Gate 1, it’s poised for improvement. The inside draw allows for a ground-saving trip, and its Real Steel x Awesome Again pedigree is ideal for Funabashi’s demanding surface.
Dark Horse Candidate
Brings JRA 2-win class form, a huge advantage here. The outermost gate is a blessing, as it dislikes kickback. Expect this son of Danon Legend to use its natural dash to seize the lead and attempt to go wire-to-wire. A very real threat if it gets its own way up front.
Special Mention Longshot
The chaos candidate. If the pace is hot, watch for this one. Despite a slow start last race, it uncorked a powerful late run for third. Now in its third start after a break (“tataki 3-runme”), it’s at peak fitness and can slice through the field to hit the board.
Capable Horse
Don’t sleep on this one despite the layoff. The stable is confident, and its excellent record when fresh (“teppou”) is a major plus. With top Minami Kanto jockey Tsubasa Sasagawa aboard, its high AI place rate makes it a must-include for trifecta tickets.
The Break: From the outside, 11. Sirius surges for the lead, challenged by 1. Fast Lane from the rail. 5. Joyful Rock effortlessly settles into a prime stalking position.
The Turn: Hitting the spiral curve, 5. Joyful Rock makes its move, accelerating with devastating ease and applying immense pressure.
The Stretch: 5. Joyful Rock explodes away from the field, extending its lead with every stride. The real race is for second, a frantic battle between a tenacious 1. Fast Lane, a fading 11. Sirius, and the late-charging 2. Crown Bravo.
With Joyful Rock’s odds likely very low, we target value in a 3-Win Trifecta formation.
