Japanese Car Inspections Made Simple (Dealers’ Insights)

Buying a used car from Japan sounds scary, right? You are sitting on the other side of the world, sending money for a car you have never seen.

But here is the good news: Japan has one of the strictest car inspection systems on the planet. At Nexuss Cars, we believe you should never have to guess what you are buying. So, let us break down those official Japanese inspection papers in the simplest way possible. No fancy words. Just straight talk.

🚐 What Is This Paper You Get?

Every certified used car in Japan goes through a tough check-up by trained experts. Groups like the Japan Automobile Appraisal Association (JAAA) make sure everything is fair and honest.

At the end of this process, you get a Vehicle Inspection Certificate. Think of it like a report card for the car. It uses numbers, letters, and even drawings to tell you exactly what shape the car is in.

1. The Big Number: The Overall Score

The most important thing on the paper is the Overall Rating Score. It uses a scale from S (the best) down to R (the worst).

Here is what those numbers actually mean in plain English:

GradeWhat It Really Means
Grade SAlmost new. Less than a year old and under 10,000 km.
Grade 6Super clean for a used car. Under 3 years old and under 30,000 km.
Grade 5Excellent. Very tidy with under 50,000 km.
Grade 4.5The sweet spot. Very reliable and under 100,000 km. Best value.
Grade 4Good. A few tiny scratches, but nothing serious.
Grade 3.5Normal used car. Has some small scratches and dents you would expect.
Grade 3 / 2 / 1More noticeable flaws. Still runs fine, but looks rough.
Grade R / RAHad frame or structural repairs. Usually fixed properly.

2. The Letters: Inside and Outside

Besides the big number, inspectors give separate letter grades for the outside (exterior) and the inside (interior). These go from A (perfect) to E (rough).

For the Outside (Paint and Body):

  • A: Spotless. Almost no scratches.
  • B: A few light scratches, but normal for the age.
  • C: Average. Has some small dents you can see.
  • D or E: Lots of scratches and dents all over.

For the Inside (Seats and Cabin):

A: Showroom clean. No stains or tears.

B: Very clean with tiny signs of use.

C: Normal used car. Has visible wear, but nothing crazy.

D or E: Dirty, torn, or damaged. Needs some fixing.

🚚 3. The Big Question: Has It Been in an Accident?

This confuses a lot of people.

In Japan, a car only gets a “Repair History” stamp if the main body frame (the skeleton of the car) was fixed.

If the car just had a door replaced or a fender repainted? That does NOT count as a repair history. That is just cosmetic stuff. This rule helps you tell the difference between a fender-bender and a major crash.

📦 4. The Drawing: The Map of Scratches

Every certificate has a little drawing of the car. It looks like a map with letters and numbers pointing to different spots.

  • Letters = The Type of Flaw:
    • A = Scratch
    • U = Dent
    • B = Scratch + Dent together
    • S = Rust
  • Numbers = The Size:
    • 1 = Tiny (about 10cm, like a hairline scratch)
    • 3 = Big (about 40cm, a large scratch)

So, if you see “A2” on the front bumper, it means a medium-sized scratch on the front bumper. Easy, right?
