Despite being free 24-hour rest facilities, Japan's roadside stations (Michinoeki) and service/parking areas are experiencing ongoing issues due to some users treating them as overnight camping sites. The core problem is a widespread misunderstanding: users are confusing 'car camping' for leisure with the permitted act of taking a short nap for driver safety. Authorities clarify that while short naps are acceptable, using these public spaces for overnight stays, cooking, or recreational activities is discouraged.
