Shaken costs calculator

If you own a car in Japan, you’ll eventually meet Shaken (車検) — the mandatory vehicle inspection that keeps cars safe, insured and legally on the road.

It happens three years after first registration and then every two years. While the process is standardized nationwide, costs vary by vehicle type, weight and age, and by where you choose to do the inspection.

In 2025, most drivers are asking two things: “How much will Shaken cost me?” and “How can I avoid overpaying?” 

The short answer is that the bill is a combination of fixed items (mandatory liability insurance and taxes) plus service fees(dealer vs local garage vs do-it-yourself at an inspection center). The longer answer depends on your car.

What makes up your Shaken bill

A typical Shaken invoice includes:

• Mandatory Liability Insurance (自賠責保険 / Jibaiseki Hoken) – set by law for the full Shaken period.
• Weight Tax (自動車重量税) – tied to vehicle category/weight and impacted by age; older cars tend to pay more.
• Inspection Service Fee – the biggest variable. Dealer convenience costs more; local garages are usually cheaper; DIY at the inspection center reduces labor but requires paperwork and prep.
• Minor maintenance & parts – wipers, bulbs, fluid top-ups and any fixes needed to pass.

Because those pieces move together, the final amount for a kei car is often much lower than for a large SUV, and a newer compact will typically pay less tax than an older heavyweight.

Typical price ranges (2025)

While every case is different, these market ranges help you plan:

• Kei car (軽自動車): around ¥55,000–¥70,000
• Small sedan / hatch (≤1.5t): ¥80,000–¥100,000
• Midsize SUV / large sedan (1.5–2.0t): ¥100,000–¥120,000
• Large SUV / van (2.0t+): ¥120,000–¥150,000
• EV: ¥70,000–¥90,000 (insurance/tax profile differs)

Those ranges already include insurance + taxes + a typical service fee. If your car is 13+ years old, expect an uplift; likewise, dealer service tends to push totals toward the upper end.

Try the calculator

To remove the guesswork, use our Shaken calculator. Choose your vehicle category, whether it’s under or over 13 years old, and your service option (dealer, local garage or DIY). You’ll see an estimated range and a midpoint for budgeting. It’s quick, transparent and adapts to your inputs.

How to reduce your Shaken cost

• Shop the service fee. Ask a local garage for a quote; they often beat dealer labor while meeting the same legal standards.
• Handle small fixes early. Replace worn wipers, bulbs or tires before inspection day so you don’t pay twice or fail for minor issues.
• Stay on schedule. Driving without valid Shaken is illegal; waiting until the last minute can limit your options and increase stress.
• Keep maintenance regular. Well-maintained cars sail through inspection with fewer surprises.
• Consider DIY at the inspection center. If you’re comfortable with paperwork, this can trim fees (but plan time for forms and rechecks).

Where to book

You can pass Shaken at dealerships, independent garages and official inspection centers. Dealers are convenient and thorough but usually cost the most. Independent garages offer good value and can coordinate parts in advance.

Going direct to the inspection center minimizes fees but shifts admin to you. Choose the route that matches your budget and comfort with the process.

Bottom line

Shaken is predictable when you break it down. Fixed insurance + tax, plus a service fee that you control by where you book. Use the calculator below to get a realistic range for 2025, plan your maintenance, and choose the service path that fits your time and budget. Being prepared means passing smoothly — without paying more than you should.
