Shimanoyama Region Treasure Location in Forza Horizon 6
If you look right at the northeastern edge of the Shimanoyama region on the Forza Horizon 6 map, you should see a red icon with a checkered flag --this is the Shimanoyama Circuit Road Racing event.
If you fast travel there and drive through the front gate, you'll see some spots on the left for cars to get worked on. The treasure chest will be in the third slot!
Just drive your car into it to break the box and reap the rewards.
