Where to find the Takashiro region Treasure Hunt in Forza Horizon 6

This week's Treasure Hunt in Forza Horizon 6 places the chest in east Takashiro, at a rest area surrounded by pampas grass southeast of Soni Circuit. Drive right down the winding road past the Soni Circuit entrance going west to east, then turn left into the pampas grass fields and watch for the rest area on your left near the pool. Smashing the chest awards 100,000 credits, 5,000 XP, and three Season Progress, and there's a new photo challenge for extra points.
