The Shimanoyama region treasure hunt in the Summer season of Forza Horizon 6 hides its chest at the Shimanoyama Circuit, tucked into the pit lane where cars are serviced. Shimanoyama is the westernmost region on the Japan map, sitting west of Minamino and northwest of Ohtani. Break the chest and you earn 100,000 Credits along with three Season Points toward the Festival Playlist.
Quick answer: Fast travel to the Shimanoyama Circuit Road Racing event at the northeastern edge of the region, drive through the front gate, and crash into the chest sitting in the third service slot on the left.
Where the Shimanoyama treasure chest is
Look at the northeastern corner of the Shimanoyama region on the map. You are searching for a red icon marked with a checkered flag, which is the Shimanoyama Circuit Road Racing event. That marker is your fast travel target, so there is no wandering required.
The chest is not out on the track itself. It waits inside the circuit’s pit area, in the third of the service slots lined up on the left side once you pass through the gate.
How to reach and break the chest
You know it worked when the chest shatters and the reward banner appears on screen, adding the Credits and Season Points to your account immediately.
Rewards and where the Season Points go
The treasure hunt is one of the higher-paying single tasks in the Summer season, handing over far more Credits than most weekly challenges. The three Season Points feed the Festival Playlist, which you spend on this season’s reward cars.
| Reward | Amount |
|---|---|
| Credits | 100,000 |
| Season Points | 3 |
