Japan Vehicle Inspection (Shaken) Total Cost Calculator
Select your vehicle type, eco-car tax reduction category, compulsory insurance term, and recycling fee vehicle class to estimate the total shaken (vehicle inspection) cost — statutory fees plus optional maintenance and agent fees.
What the shaken total cost calculator does
Shaken costs fall into two buckets: statutory fees, which are the same amount no matter who handles the paperwork, and maintenance plus agent handling fees, which vary by provider. Statutory fees are the total of the vehicle weight tax, compulsory insurance (CALI) premium, and recycling fee, and they're determined entirely by the vehicle's class and age. This tool calculates that statutory total from your inputs and adds whatever maintenance fee and agent fee you enter, to show an estimate of the full shaken bill.
It's hard to tell whether a quote is fair because these two buckets are usually shown as one combined figure. Since the statutory fees can't be negotiated, knowing that amount up front lets you compare only the marked-up maintenance and handling portions across providers. Note that the automobile tax and environmental performance surtax, which are billed separately from shaken, aren't included in this estimate.
How to estimate your shaken cost
- Choose the vehicle type and weight Select regular or kei car; for a regular car, also pick the weight bracket shown on your vehicle inspection certificate. This sets the weight tax.
- Pick the eco-car reduction category The tax rate rises once a car passes 13 years since first registration. From the second shaken onward, standard rate or the aged-vehicle surcharge usually applies.
- Set the insurance term and recycling class Compulsory insurance is commonly bought for 25 months so it doesn't lapse before the next shaken. The recycling fee estimate depends on the vehicle class you select.
- Enter maintenance and handling fees to compare Type in the figures from a quote to see the full total. Leave both at 0 yen to see only the statutory fees.
Tips for getting more out of it
- To see only the statutory fees (weight tax, compulsory insurance, recycling fee), leave the maintenance fee and agent fee at 0 yen.
- When comparing this estimate against a dealer or garage quote, check whether their "statutory fees" line matches this tool's statutory subtotal — that makes it easier to isolate how much you're paying for labor and handling.
- Compulsory insurance is commonly purchased for 25 months (one month longer than the 2-year shaken cycle) so coverage never lapses before the next inspection.
- The eco-car reduction category is decided only once, at first registration, so most cars pay either the standard rate or the aged-vehicle surcharge (over 13 / over 18 years) from the second shaken onward.
Ways to use the shaken cost estimate
Check whether a quote is fair
Matching a quote's statutory fees line against this estimate reveals exactly how much is being added for maintenance and handling — useful leverage if you want to negotiate.
Compare multiple providers
Since statutory fees are identical everywhere, only maintenance and handling fees differ. Line up several quotes under the same conditions to judge them fairly.
Weigh doing a user shaken yourself
Set the agent fee to 0 yen to see how much you'd save by bringing the car in yourself, then weigh that against the time and effort involved.
Save up ahead of your next shaken
Divide the total by the number of months until your next inspection to see how much to set aside monthly, so the bill doesn't catch you off guard.
Shaken cost glossary
- Statutory fees
- The sum of the vehicle weight tax, compulsory insurance premium, and recycling fee. The amount is identical regardless of provider and is never discounted.
- Vehicle weight tax
- A national tax based on the vehicle's weight. The rate steps up once the car passes 13 and then 18 years since first registration.
- Compulsory insurance (CALI)
- Insurance every vehicle is legally required to carry. It's commonly purchased for 25 months so coverage doesn't lapse before the shaken deadline.
- Recycling fee
- A fee deposited in advance to cover future disposal costs. It's paid once at purchase, not at every shaken.
- Aged-vehicle surcharge
- A mechanism that raises the weight tax once a car passes a set age, in two steps: over 13 years and over 18 years.
- Agent handling fee
- What a shop charges for bringing your car to the transport bureau and processing the paperwork on your behalf. It doesn't apply if you go yourself.
Frequently asked questions
Side Note — Why shaken renews every two years
Japan's vehicle inspection and registration system (shaken) requires a first inspection three years after a new car is registered, then renewal every two years after that. This cycle is set by the Road Transport Vehicle Act and exists to regularly confirm that a vehicle's safety and emissions performance hasn't degraded below the required standard as it ages.
Among the statutory fees, the weight tax and compulsory insurance premium need to be paid and renewed at every shaken, but the recycling fee is deposited just once — either when you buy the car new, or inherited from the previous owner when you buy it used — and isn't billed again at each inspection. This tool bundles it into the statutory total anyway, so that at shaken time you have a single estimate of "how much is left to pay if it hasn't been deposited yet."
Agent handling fees vary widely between providers: dealer shaken tends to charge more in exchange for thorough inspection and genuine parts, while shaken specialist chains often keep fees low by focusing narrowly on clearing the legal minimum requirements. Which one suits you often comes down to whether you prioritize price or the depth of after-sales support.
