Forza Horizon 6 is packed with things to discover, and while the big expansions—Expansion 1 and Expansion 2—haven’t been released yet, there are already plenty of secrets and hidden unlocks on the base Japan map that you can tackle. Here’s a clear guide from an experienced gamer’s perspective.

Expansions 1 & 2: What We Know

As of May 15, 2026, players who bought the Premium Edition or Premium Upgrade Bundle automatically own both expansions. However, these DLCs are post-launch content, and no hidden unlocks or secret criteria exist in the game files yet. You’ll be able to download them once Playground Games releases the official expansion updates.

Unlocking “Discover Japan” & Legend Island

Even before the expansions, the base game has major zones and hidden areas you can explore:

Discover Japan System: To unlock areas like Legend Island and progress your regional stamp levels, focus on this system rather than just finishing races.

Earning Stamp Points: Normal Horizon Festival races don’t count. You need to complete world-exploration tasks like:

Discovering hidden roads and routes

Smashing regional mascots

Completing delivery missions and story quests

Progressing in Discover Japan opens more regions, events, and rare rewards along the way.

Hunting Secret Cars & Barn Finds

Forza Horizon 6 keeps its collection exciting with secret cars scattered across Japan. There are two main types of map secrets:

Barn Finds (15 Cars)

These are traditional hidden cars, but you can’t claim them immediately.

Each barn is locked behind a Discover Japan progression requirement.

For example, the rare Honda NSX-R GT won’t be yours until your stamp tier in that region reaches the necessary level.

Hidden Treasure Cars (9 Cars)

Each comes with a postcard clue for the region.

Unlike barn finds, no level requirements are needed.

You just need to reveal the map’s fog of war to activate the clue notification and track down the car.

Pro Tips for Early Progression

Explore Thoroughly: Even if you don’t need a specific car, reveal roads and landmarks to earn stamp points faster.

Track Postcards: Hidden treasure cars are easier if you pay attention to the visual/text clues.

Prioritize Regions: Some zones have multiple collectibles; finishing one region fully can unlock bonuses in others.

Even before Expansion 1 and 2 drop, mastering the Discover Japan system and hunting down hidden vehicles gives you a solid head start for when the new content goes live.
