If you're working through the Horizon Decades Summer Playlist, the Short Circuit task at Shimanoyama can be one of those events that looks simple until it isn't. You just need a win in an 1980s car, plus the usual bit of patience, and the reward is a Playlist point with a small pile of FH6 Credits on top. That sounds easy enough, but plenty of players still miss it because the game is picky about which race actually counts.

Finding the right event

The main thing to know is that not every race in the area will do the job. Shimanoyama Circuit is the one you want, not the sprint, not a custom route, and not some EventLab version that looks close enough. That is where a lot of people trip up. They race well, they win, and then nothing pops. It can be annoying, sure, but the fix is simple once you know what to look for. Head to the standard Festival event at Shimanoyama Circuit, pick the proper race, and leave the custom stuff alone for this one.

Which 1980s cars work best

You do not need a wild build here. In fact, going too hard on power usually makes the car harder to place through the corners, and this circuit asks for control more than brute force. A light car with decent grip will usually feel much better than something that just chases top speed. The 1984 Honda City E II is a solid pick because it turns in cleanly and does not feel twitchy. The Nissan Be-1 is another easy choice if you already have it. The Nissan PAO can also get the job done with a bit of tuning, and the Nissan S-Cargo is strange but still usable if it's what you've got sitting in the garage. You'll probably notice pretty fast that the winner here is the car that stays settled, not the one with the biggest numbers.

How to make the race easier

If you want this done quickly, spend your upgrade points on grip, brakes, and suspension before you think about horsepower. That is the kind of setup that makes sense on a tight circuit. A stable car lets you carry speed out of corners, and that matters more than a flashy top-end run down a short straight. It also helps to brake earlier than you think you need to. A lot of the turns tighten up just enough to catch you if you come in hot. Keep your lines tidy, avoid clipping walls, and use Rewind if you botch a corner badly. There's no reason to throw away a clean run when the event is only a couple of minutes long.

What players usually get wrong

The most common mistake is choosing the wrong event and assuming the challenge is bugged. It usually isn't. Most of the time, the game just didn't see the exact race it wanted. Another mistake is bringing a car from the wrong decade and not noticing until the finish line. If you are only after the Playlist point, you can also lower the Drivatar difficulty and make the whole thing far less stressful. That's not cheating. It's just being efficient. Once you know the event is the real Shimanoyama Circuit race and your car is actually from the 1980s, the challenge is straightforward.

Final Thoughts

This is one of those daily tasks that sounds like busywork, but it goes faster than most people expect when you set it up properly. Pick the right circuit, use a sensible 1980s car, and lean into grip instead of raw speed. That's really the whole deal. If you're also keeping an eye on seasonal rewards, it's worth clearing these small objectives as they come up.
