The Inner City Run Drift Zone in Forza Horizon 6 is situated within Tokyo City's northern park and serves as the venue for a timed drift challenge as part of the Horizon Decades Festival Playlist. The zone features a winding road through the park with natural hazards, including proximity to a lake that can end attempts if drivers veer off course.

Completion requires players to accumulate 45,000 points whilst drifting, with the added constraint of using only vehicles manufactured in the 2000s. Winter weather conditions further complicate the task, as snow-covered areas yield no points, forcing drivers to stay on the main road and maintain controlled, continuous drifting throughout the course.
