SHAKEN - Car Inspection system
The inspection system is in place to ensure that vehicles on Japanese roads are properly maintained and are safe to be on the road. Another reason is to determine if a vehicle has been illegally modified. Illegally modified vehicles and vehicles deemed unsafe will have a red sticker with the following: fuseikaizousha(不正改造車) (Illegal Vehicle) in yellow and the date the vehicle was declared not fit to be on the street.
I have recently used the service at ENOS gas station at Tsukushima and it was very reasonable.
