Forza Horizon 6: Horizon Decades

Forza Horizon 6‘s second festival playlist, Horizon Decades, has officially kicked off. The first season to tackle is Summer, and it’s packing in plenty of challenges to keep you busy over the next seven days. However, few are as tricky as trying to find the Nangan Region Treasure Hunt somewhere along the coast.

Whether this is the first Horizon Decades challenge you’re tackling, or you’ve saved it for last, you won’t want to miss completing it. So, if you’re finding yourself stuck, don’t fret — we’ll explain where to find the Horizon Decades Nangan Region Treasure Hunt below.

Where To Find The Horizon Decades Nangan Region Treasure Hunt

To find the treasure chest for the Horizon Decades Nangan Region Treasure Hunt, you’ll need to head to the (surprise!) Nangan region, which is located on the southeastern side of the map. This treasure chest is located along the lower coast of the region, south of Tokyo City. For the exact spot, reference the map above.

To reach this spot on the beach, you’ll need to drive or fast-travel to the road just left of it, then drive carefully down the slope. This is the only way to get to this point on the coast, as a rock formation will be blocking your way if you try to approach from the north along the beach.

For finding this treasure chest, you’ll earn 100,000 credits and three points toward the overall seasonal track. This gets you a little bit closer to wrapping up this week’s requirements.

Indeed, finding the treasure chest may complete one of this week’s challenges, but you still have quite a few more to go. If you’re gunning for all of the Horizon Decades rewards, you won’t want to leave anything unfinished, so get back out there and keep driving.

Forza Horizon 6 is available on Xbox Series X|S and PC, with a PS5 version slated for later in 2026.
