Your Japanese car has arrived in the UK, it looks great, and it drives smoothly. You’re ready to hit the road but not yet. First, the UK government needs to check that your car is safe for British roads. This check is called the IVA test Individual Vehicle Approval.

Many first-time importers have never heard of it, and then get surprised by the £200 test fee and the long waiting list.

At Nobuko Japan, we pre-check every car for IVA compliance before you even bid, saving you time, money, and stress. This post tells you exactly what the IVA test is, which cars need it, and how to pass on your first attempt.

What Is the IVA Test?

The Individual Vehicle Approval (IVA) test is a government test on imported cars in the UK. It ensures that your car is up to British environmental and safety standards.

Think of it as an MOT on steroids. It is stricter, more detailed and happens before your car is allowed on UK roads.

What the IVA checks:

Lights (dip beam, main beam, indicators, fog lights, reverse lights)

Brakes (performance and balance)

Steering and suspension

Tyres and wheels

Seatbelts and restraints

Glass (windscreen, windows)

Speedometer (must show mph, not just km/h)

Exhaust emissions

Noise levels

Mirrors (rear view and side)

What the IVA does NOT check:

General engine condition

Bodywork scratches or dents

Interior wear and tear

Bottom line: The IVA is about safety and legality. Not cosmetic condition.

Which Japanese Imports Need an IVA Test?

This is where most buyers get confused. The rule is simple.

The 10-year regulation: Age is determined by the first issuance of the car in Japan, to the day it enters the UK. 

Example: A 2017 Toyota Voxy arrives in the UK in 2026. That is 9 years old so it needs an IVA test.

A 2014 Toyota Voxy arrives in 2026 which is 12 years old. No IVA needed, straight to MOT.

Nobuko Japan tip: If you want to avoid the IVA completely, buy a car that is 10 years or older. You save £200–£300 and weeks of waiting.
 

What Happens During the IVA Test?

The test takes 1–2 hours at a designated DVSA test centre. There are 20+ centres across the UK.

Step-by-step:

1. Booking: You book online via the DVSA portal. Wait times vary: 2–6 weeks depending on location.

2. Arrival: You drive (or trailer) your car to the test centre. Bring the car, the fee, and your import documents.

3. Inspection: A DVSA examiner has to complete a 60+ point checklist. They employ measuring devices, emission meters, and brake testers.

4. Result: Pass or fail. If you pass, you get an IVA certificate (valid for 6 months). If you fail, you get a failure report listing what needs fixing.

5. Retest (if needed): Fix the problems, book a retest (reduced fee: £100–£150). Pass within 6 months or start over.

Cost: £200 – £300 for the first test. Retests are cheaper.

Common IVA Failures on Japanese Cars

Japanese cars are built for Japanese roads. UK roads have different rules. Here is what fails most often.

Failure #1: Rear Fog Light (80% of failures)

Japanese cars do not have a rear fog light but UK law requires one.

Solution: Install a red rear fog light on the driver's side (right side) or centre. Cost: £50–£150 at a garage.

Failure #2: Speedometer in km/h Only

UK law requires the speedometer to show miles per hour (mph). Many Japanese cars show only km/h.

Solution: Digital speedometers often have a hidden mph setting (check the manual). Analogue ones need a new dial face or converter box. Cost: £50–£200.

Failure #3: Headlight Beam Pattern

Japanese headlights dip to the left (for driving on the left in Japan). UK requires dip to the right.

Solution: Adjustable headlights can be realigned. Fixed ones need beam deflectors or replacement units. Cost: £20–£300.

Failure #4: Exhaust Emissions

There are performance cars in Japan (Skyline, Evo, Impreza) with altered exhausts. They cannot pass the emissions tests in the UK.

Solution: Reinstall the original catalytic converter. Cost: £200–£500.

Failure #5: Tyres

Japanese tyres may not have the UK E-mark certification.

Solution: Replace with UK-approved tyres. Cost: £200–£400 for a set.

Nobuko Japan tip: We check all five of these issues before you bid. If a car needs work, we tell you upfront, no surprises at the test centre.

Experience Section 

Real Example: Buyer Failed IVA Twice – Cost £1,145

A UK customer imported a 2016 Nissan Elgrand from an online auction, unaware of IVA requirements. The car arrived, and he booked the test.

First test – FAIL. Issues: no rear fog light, speedometer in km/h only, headlights dipping wrong way. He fixed the fog light (£120), bought a mph converter (£80), beam deflectors (£15), and paid a £150 retest fee.

Second test – FAIL again. Converter wired incorrectly, speedometer still in km/h, deflectors fell off. He paid £180 to an auto electrician, bought replacement headlights (£250), and rebooked (£150).

Third test – PASS. Total cost: £500 in test fees + £645 in repairs = £1,145.

He said: "I thought I saved money buying from Japan. I spent over £1,000 on IVA issues I never knew about."

Lesson: Always pre-check IVA compliance before bidding.

How to Pass the IVA Test First Time

Follow this checklist before you book your test.

Pre-test checklist:

Rear fog light installed (red, driver's side or centre)

Speedometer shows mph (digital or analogue)

Headlights dip to the right (or have beam deflectors)

Tyres have UK E-mark (look for a circled E on the sidewall)

Exhaust has a catalytic converter (no straight pipes)

All lights work (brake, indicator, reverse, number plate)

Seatbelts retract and latch properly

Windscreen has no cracks in driver's line of sight

Mirrors are present and secure

Horn works

Nobuko Japan service: We check all 10 items before your car leaves Japan. If something is missing, we either fix it in Japan (cheaper) or warn you before you bid.

IVA vs MOT What Is the Difference?

Many buyers confuse these two tests.

What Happens After You Pass the IVA?

You have the IVA certificate. Now finish the registration process.

Step 1: Get insurance (even if you are not driving yet – needed for registration).

Step 2: Take your IVA certificate, insurance certificate, and import documents to the DVLA.

Step 3: Pay the first registration fee (£55).

Step 4: DVLA issues a UK log book (V5C) and assigns a UK number plate.

Step 5: Get physical number plates made (£25).

Step 6: Pay road tax (varies by CO2, £50–£200 per year).

Step 7: Book an MOT (if car is over 3 years old – most imports are).

Step 8: Drive legally.

Total post-IVA cost: £55 (registration) + £25 (plates) + £50–£200 (tax) + £40–£60 (MOT) = £170–£340

Cars That Are Exempt from IVA

You do NOT need an IVA test for these vehicles:

Cars 10 years old or older (from first registration date)

Classic cars (over 40 years old – different rules)

Cars imported from within the EU (different rules post-Brexit – check current guidance)

Cars temporarily imported (non-UK residents, limited time)

Nobuko Japan tip: If you want the simplest import, buy a car that is 10+ years old. No IVA, go straight to MOT. Lower cost and definitely less hassle.

Conclusion

The IVA test for Japanese imports is mandatory for cars under 10 years old. It costs £200–£300. The most common failures are rear fog lights, speedometer in km/h, and headlight beam pattern.

Failing the IVA is expensive since each retest costs £100–£150. Repairs add hundreds more.

Nobuko Japan pre-checks every car for UK compliance before you bid. We identify missing fog lights, mph issues, and beam problems. You fix them cheaply in Japan or choose a different car.
