It is the Grand Prix. The fans have voted, the snow is threatening to fall over Nakayama, and that iconic fanfare is about to blast through your speakers. If you’ve spent any time in the trenches of Uma Musume Pretty Derby, you know the Arima Kinen isn't just another race on the schedule. It's the end-of-year boss fight. Honestly, it’s the moment that makes or breaks a training run, and for many players, it’s the source of more "Rank G" heartbreak than anything else in the game.
The Arima Kinen is weird. It’s 2500 meters. That sits in this awkward middle ground—longer than a standard 2400m Long-distance bout but technically classified as Long-distance for skill activation purposes. You’re hitting that final corner, the stamina bar is flickering red, and suddenly Oguri Cap or TM Opera O comes screaming past you. Why? Because most people treat it like a slightly longer Japan Cup. Huge mistake.
The Stamina Trap in Uma Musume Arima Kinen
Let’s talk numbers. To even survive the Arima Kinen in the URA or Grand Masters scenarios, you need stamina. A lot of it. But here is the kicker: the Nakayama track has a nasty uphill climb near the end. If your "Guts" stat is bottomed out, your girl is going to "hit the wall" regardless of how much blue stamina recovery you've packed.
I’ve seen builds with 800 Stamina get absolutely shredded because they ignored the "Power" requirement to push through the final slope. It’s brutal. You’ve got to balance. If you are running a "Long" distance specialist like Gold Ship, you basically want to aim for at least 700 Stamina with at least one gold recovery skill like Maestro of the Depths (円弧のマエストロ). Without that? You’re just praying for a lucky proc that probably won't come.
The Arima Kinen represents the culmination of the "Senior" year. In the game’s logic, this is where the difficulty spikes to match the historical prestige of the real-life race. In reality, the Arima Kinen is Japan's most bet-on race. In the game, it’s where your dreams go to die if you didn’t build for the specific quirks of the Nakayama 2500m layout.
Why Position Matters More Than You Think
Is your Uma Musume a Runner (Escape) or a Chaser? In the Arima Kinen, the "Inner" track is tight. If you’re playing a Betweener (Insert), you can get boxed in so easily it’s frustrating.
Think about Kitasan Black. In the game, her speed is legendary, but if she doesn't grab the lead early in the Arima, she’s toast. The 2500m distance means there is a long stretch to recover, but the final straight at Nakayama is famously short. Unlike the Tokyo Racecourse where you have a massive stretch to make up ground, Nakayama demands that you are already making your move before you even see the finish line.

- Runners: Need high Lead (Sustained Speed).
- Leaders: Must have high Positioning skills to avoid getting swallowed by the pack.
- Betweeners/Chasers: They need "Non-Stop Girl" or similar acceleration skills because the traffic jam in the final corner is a nightmare.
Seriously, if you haven't equipped an acceleration skill that triggers on a slope or a corner, you’re essentially giving up. The AI in the Arima Kinen is programmed to be aggressive. They will bump you. They will block you. It's a dogfight.
The Ghosts of Real Turf: Why History Dictates Your Wins
Cygames loves history. They bake it into the hidden stats. Take Tokai Teio. Her "Miracle Comeback" in the 1993 Arima Kinen is legendary—returning from a 364-day injury layoff to win. In the game, her internal logic and skill kit are designed for that specific Nakayama theater.
If you’re struggling, look at the characters who historically dominated this race.
- Grass Wonder: The "Arima Killer."
- Symboli Rudolf: The Emperor.
- Rice Shower: The "Heel" who broke hearts.
Using these characters gives you a slight edge not just because of their stats, but because their unique skills (Uniques) often trigger perfectly for the 2500m distance. Grass Wonder’s Winged Spirit is practically built for the Nakayama stretch. If you are trying to win with a girl who is naturally a Miler (like Sakura Bakushin O), you are essentially playing Dark Souls with a broken sword. It can be done with enough Stamina inheritance, but man, it is an uphill battle.
Building the "Arima Ready" Character
Stop focusing only on Speed.
I know, I know. "Speed is meta." But in the Arima Kinen, Speed is the ceiling, while Stamina and Power are the floor. If the floor collapses, the ceiling doesn't matter.

For a solid Arima Kinen run, specifically for Champions Meeting or high-level CM events, you should prioritize a 1200 Speed / 800+ Stamina / 1000 Power split. And don't sleep on Intelligence. High Intelligence (700+) ensures your Uma Musume actually uses her skills. There is nothing worse than watching your 1200 Speed Mejiro McQueen stay silent and finish 8th because she forgot how to use her recovery skills.
The weather and track condition are also factors. Arima is usually "Heavy" or "Snowy." This saps stamina even faster. If you see that snow icon, subtract 50-100 effective stamina from your girl. It's that punishing.
The Mental Game: Handling the Pressure
The Arima Kinen is usually the final goal for many training scenarios. If you lose, you lose out on a massive chunk of fans and stat bonuses.
The trick is the "Summer Camp." If you don't fix your stamina during the Senior Summer training, you won't fix it by December. Use those four turns in August to spam the Stamina or Power workouts. Even if your Speed is lagging, you can catch up on Speed in the autumn. You cannot "panic train" Stamina in November. It just doesn't work.
Also, check your supports. If you aren't bringing a friend card or a support that gives a Gold Stamina skill—like Super Creek’s Maestro—you are basically gambling with your TP (Training Points).
Actionable Steps for Your Next Arima Run
Forget the "All-Speed" builds for a second. If you want to actually win the Arima Kinen consistently, you need a different blueprint.

First, look at your inheritance. Stop taking 9-star Speed parents. Take at least one parent with 9-star Stamina. This gives you a massive cushion so you don't have to hit the Stamina training button every single turn. It frees you up to build Power, which you'll need for that Nakayama hill.
Second, prioritize "Corner" skills over "Straight" skills. The Arima Kinen layout is mostly curves. Skills like Arc Maestro or Long Distance Corner offer way more value than Straight Venturer because of where the stamina consumption peaks.
Third, watch the "Debuff" meta. In high-level Arima Kinen play, people love using "Nice Nature" to drain your stamina. If you are on the edge of your stamina limit, a single Gaze or Distraction skill from an opponent will sink you. Always build a "buffer" of about 50 extra stamina points just to account for these debuffs.
Finally, pay attention to the "Inherent" skills. Some Uniques, like those of Seiun Sky, only work if you are in the lead. If you are running against three other Escape types, your chances of winning the Arima Kinen drop to near zero. Diversity in your team composition is the only way to safeguard against bad RNG.
Get back into the training room. Focus on the "Mid-game" transition. If you can't hold a good position by the time you hit the third corner, the Arima Kinen is already over for you. Speed wins races, but Stamina and Strategy win the Grand Prix.
