Compulsory Vehicle Inspection - JCI/Shaken(車検)

What is Shaken?

A vehicle inspection (shaken or JCI) is compulsory for all vehicles in every 2 years, it ensures that all vehicles on the road are properly maintained and safe to drive. The inspection also checks that vehicles have not been illegally modified.

The inspection must be carried out at an authorized service garage or at the Land Transport Bureau. Inspection and maintenance services can also be found at most car dealers. Before proceeding the inspection, the service garages and dealers normally provide you with an estimate but the price may also vary depending on the types of your vehicles such as Yellow-plate or White-plate.

Please check the expiry date of your vehicle inspection on your Shaken/JCI certificate referring the below image.

Q. I pay automobile tax/light-sized vechile tax every year. Do I still have to pay weight tax which is listed as one of the shaken costs?

A. Yes. They are different types of taxes. Automobile tax/light-sized tax is levied by a local government(prefecture/municipalities), while the weight tax is levied by the central government.

The weight tax is normally paid along with other costs when a car goes through compulsory bi-annual Shaken inspection(JCI), while automobile tax/light-sized vehicle tax must be paid separately by the owner in the beginning of every fiscal year. (usually the due is 31st May)
