The Series 4 Week 3 Horizon Mascot Party Winter season includes a Treasure Hunt that sends players to a surprisingly specific location. If you are looking for an easy source of FH6 Credits, this activity is worth adding to your weekly routine because the actual objective takes only a few minutes once you understand the route.

The reward is particularly straightforward. Completing the Treasure Hunt gives 100,000 FH6 Credits and 3 Seasonal Points. There is no difficult race at the end, so players who prefer quick Festival Playlist activities can clear this one without changing their usual setup.

The Ohtani Starting Point

The hunt takes place in the Ohtani region, which is located roughly in the center-south portion of the map and just northwest of Tokyo City.

Open your map and move toward Ohtani before searching for smaller roads. The area can initially look fairly large, but the Treasure Hunt is tied to a specific landmark. Once you identify that landmark, you can ignore most of the surrounding region.

The landmark you need is Matsumi Great Bridge.

Why The Bridge Matters

Matsumi Great Bridge is not just a general clue. The treasure chest is positioned directly underneath the bridge, which means the bridge gives you an exact starting point for the final search.

Zoom in on the map and look at the roads around the structure. There should be a small off-road dirt route passing underneath the bridge. Depending on the map display, you may see it represented by a white dotted line or an orange/checkered route.

This dirt path is much more important than the main road crossing the bridge.

Getting Under The Bridge

Once you find the dirt path, drive toward the underpass. If possible, fast travel to the dirt road or a nearby point such as the Minami Curve speed zone.

From there, head toward the bridge structure rather than following the road above it. Your car needs to reach the lower area directly beneath Matsumi Great Bridge.

The route is not particularly technical. Any normal car that can reach the dirt road should be fine. The challenge is mainly about recognizing where the chest has been placed.

Search Around The Central Support

When you enter the area beneath the bridge, start looking around the central pylon. The chest is resting against the support on the northern side.

This is the most useful detail to remember if you are trying to complete the Treasure Hunt without following a long route. You do not need to search every part of the underpass.

If you cannot see the chest right away, reposition your car around the central support and check the northern side. The chest can blend into the surroundings when viewed from a distance, particularly if you are approaching quickly.

The Final Move

After locating the wooden chest, there is nothing complicated left to do. Simply drive into it.

The chest breaks when your vehicle hits it, and the Treasure Hunt is completed immediately. You do not need to activate another objective or return to a Festival Playlist screen before receiving the reward.

This is one reason the activity is worth completing even if Treasure Hunts are not normally your favorite part of the weekly rotation. The time investment is low once you know the location.

Making The Hunt Faster

The best approach is to avoid wandering around Ohtani. Start by locating Matsumi Great Bridge on the map, then zoom in and identify the dirt route underneath it.

Using the nearby Minami Curve speed zone as a reference can also make navigation easier. Once you reach the lower road, reduce your speed as you approach the bridge. A slower approach gives you enough time to spot the central pylon and the wooden chest.

There is no benefit to driving around the surrounding roads after you reach the correct area. The chest is close to the bridge support.

What You Get For Completing It

The Treasure Hunt provides two useful rewards for a relatively small amount of effort. The 100,000-Credit payout can help with future purchases, while the 3 Seasonal Points contribute toward your Series 4 Festival Playlist progress.

For players trying to complete as much of the Winter playlist as possible, these points can be valuable when they are close to a reward threshold. Even if you are not actively chasing every playlist reward, the chest is quick enough that there is little reason to skip it.

Final Location Reminder

The whole route can be reduced to a few landmarks: travel to Ohtani, locate Matsumi Great Bridge, find the dirt road underneath it, and drive toward the central pylon. Check the northern side of the support and smash the wooden chest when you find it. For players saving up Forza Horizon 6 Credits, this is a quick activity that provides a useful reward without requiring a long race or complicated challenge.

With the location understood, the Winter Treasure Hunt becomes a quick and reliable part of a Series 4 Week 3 session, leaving you plenty of time to focus on the other activities in the Horizon Mascot Party season.
