Every Japanese auction sheet carries a grade — a single number or letter assigned by a licensed Japanese inspector after physically examining the vehicle. It is the single most important number on the sheet. Understanding exactly what each grade means, how inspectors assign them, and which grade to target for your budget is essential knowledge for any buyer importing a Japanese car.
This guide covers every grade on the Japanese auction sheet scale — from S (brand new) down to 1 (severe damage) — plus the R and RA grades for repaired vehicles, interior grades, and exactly what each grade means for a buyer in Pakistan, Kenya, UAE, New Zealand or anywhere else in the world.
How Japanese Auction Grades Are Assigned
Before looking at the grade scale, it is important to understand who assigns the grade and how — because this is what makes Japanese auction grades so reliable compared to used car listings anywhere else in the world.
Every vehicle entered into a Japanese auction is physically inspected by a licensed inspector employed directly by the auction house — not by the seller or the importer. The inspector walks around the entire car, examines the body panels, interior, engine bay and under-body, then marks every scratch, dent, stain and repair on a standardised damage diagram. This inspection takes 15 to 20 minutes per vehicle and follows rules set by the auction house.
The inspector assigns two grades: an exterior condition grade (the main grade shown as S, 6, 5, 4.5, 4, 3.5, 3, 2, 1, R or RA) and a separate interior grade (A, B, C or D). Both appear on the auction sheet alongside the full damage diagram.
Why this matters: Because the grade is assigned by an independent inspector — not the seller — it is one of the most reliable used car condition assessments available anywhere in the world. A Japanese grade 4.5 means the same thing whether the car was sold at USS Tokyo, TAU Osaka or LAA Kyoto.
The Complete Japanese Auction Grade Scale
The full grade scale runs from S (showroom condition) down to 1 (severely damaged), with additional R and RA grades for repaired vehicles. Here is every grade with a full explanation — click any grade to expand it:
An S grade vehicle is essentially brand new — often a cancelled factory order, a display model, a delivery-mileage car or a vehicle stored and never used. These are genuinely the rarest cars at Japanese auction. In a typical week across all auction houses, only a handful of S grade cars appear.
- Mileage is almost always under 1,000km
- No damage marks whatsoever on the damage diagram
- Usually carries remaining factory warranty
- Price is typically within 10–15% of new retail price
Buyer advice: If you see an S grade car at an unexpectedly low price, verify the auction sheet immediately. S grade at normal auction prices almost certainly means a data entry error, a fraudulent listing, or a car that has been misidentified. Genuine S grade cars command premium prices with competitive bidding.
Grade 6 is the practical top grade for most buyers. These vehicles are near-new condition — typically ex-dealer stock, cancelled orders or very early lease returns. Mileage is usually under 10,000 to 20,000km with no damage marks and a perfectly clean damage diagram.
- Typical mileage: 5,000–20,000km
- No accident history, no panel repairs
- May carry remaining manufacturer warranty
- Priced significantly above Grade 5 — expect to pay 15–25% more for the same model
Buyer advice: Grade 6 is excellent value if you find one at a reasonable price. It offers near-new condition without the S-grade premium. Particularly common with Toyota, Honda and Nissan kei cars that dealers return after short-term loan or display use.
Grade 5 is the most sought-after practical grade for serious buyers worldwide. It means the vehicle is in excellent condition — no accident history, no panel repairs, only very minor cosmetic wear such as light stone chips or small surface scratches that are completely normal on any used car. The majority of well-maintained Japanese vehicles fall in the 4.5 to 5 range.
- Typical mileage: 20,000–80,000km depending on age
- Damage diagram shows only A1 or A marks at most — very light scratches
- No accident history, no repairs, no structural work
- Best balance of condition, availability and price
- Widely available across all auction houses and vehicle types
Buyer advice: Grade 5 is the standard recommendation for private buyers importing from Japan. If your budget allows Grade 5, prioritise it over Grade 4.5 — the difference in long-term reliability and resale value is significant.
Grade 4.5 is very close to Grade 5 — the difference is a few more cosmetic marks on the body. The damage diagram may show a couple of A or B marks (light scratches or small dents) but no accident history and no panel repairs. These vehicles are mechanically identical to Grade 5 cars with slightly more visual wear.
- Typical mileage: 30,000–100,000km
- Damage: A or B marks on 1–3 panels — scratches or minor dents
- No accident history, no structural repairs
- Typically 10–20% cheaper than the same car at Grade 5
Buyer advice: Grade 4.5 is the sweet spot for value buyers. The cosmetic marks rarely affect daily use and the price saving versus Grade 5 is meaningful. Always check the damage diagram — a Grade 4.5 with two A marks on a door is very different from one with a B mark on a front panel.
Grade 4 vehicles are in good condition with more visible cosmetic wear. The damage diagram typically shows B or C marks on multiple panels — small dents, light scratches across several areas. No accident history and no structural repairs, but the exterior shows its age more clearly.
- Typical mileage: 50,000–150,000km
- Damage: B or C marks on several panels
- No accident history in most cases — always verify the full sheet
- Typically 20–35% cheaper than Grade 5 for the same model and year
Buyer advice: Grade 4 is acceptable for buyers on a budget. Read the damage diagram carefully — where are the marks and what type are they? A Grade 4 with marks only on doors and bumpers is far better than one with marks on structural panels. Always verify the full auction sheet before bidding.
Grade 3.5 means noticeable exterior damage across multiple panels, possibly minor previous repairs. The car may have had bumper work or panel beating that was repaired well enough not to qualify for an R grade. These vehicles require careful review of the full damage diagram.
- Multiple panels with B or C damage marks
- May have had minor non-structural repairs
- Mechanically can still be sound — check engine and under-body notes
- Significant price discount versus Grade 4 or above
Buyer advice: Only consider Grade 3.5 if you have reviewed the full auction sheet in detail and understand exactly what damage is recorded. Suitable for buyers who plan repairs or for commercial use where cosmetic condition is less important.
Grade 3 means significant visible wear and damage. The car may have accident history recorded on the sheet, multiple panel repairs or heavy cosmetic damage. At this grade, the full auction sheet becomes critical — the damage diagram will show where and what type of damage exists.
- Multiple C or U marks (dents, unrepaired damage)
- May have recorded accident history or structural notes
- Can offer good value for experienced buyers who understand what they are buying
- Typically 40–60% cheaper than Grade 5 for same model
Buyer advice: A Grade 3 car with only door and bumper damage can still be worth buying at the right price. A Grade 3 with structural marks or inspector notes about frame damage is a different matter entirely. Never buy Grade 3 without reading the complete auction sheet.
Grade 2 indicates heavy overall damage — the car has significant structural or cosmetic problems that make it unsuitable for normal use without substantial repairs. These vehicles are typically bought by repair shops or parts dealers in Japan, not for export.
- Heavy structural or cosmetic damage throughout
- Not suitable for normal private use without major repairs
- Rarely worth importing — repair costs typically exceed any saving on purchase price
Buyer advice: Avoid Grade 2 for personal import unless you are a professional mechanic with a clear repair plan and cost estimate. The savings on purchase price are almost always wiped out by repair costs plus import fees.
R grade means the vehicle was involved in an accident and was repaired — but it was repaired well enough that the inspector classified it as repaired rather than damaged. Critically, the accident did not involve airbag deployment. The repairs may include panel replacement, repainting or minor structural work.
- Confirmed accident history — the vehicle has been in a collision
- Repairs were completed — but the original accident is permanently recorded
- No airbag deployment (this distinguishes R from RA)
- May look cosmetically fine but carries accident history
- Will always have lower resale value than equivalent non-accident vehicles
Buyer advice: R grade vehicles can run perfectly well for many years — the repair quality in Japan is generally very high. But you must price them accordingly. An R grade car should be 25–40% cheaper than the same model at Grade 4 or 4.5. Never pay near-Grade 4 prices for an R grade.
RA is the most serious repair grade. It means the vehicle was involved in a serious accident where the airbags deployed — indicating a significant collision — and was subsequently repaired. Airbag deployment means the collision exceeded the threshold that triggers the safety system, typically a front impact at 20–30 km/h or greater.
- Airbags deployed — serious collision confirmed
- May have had airbag replacement, structural repairs, full respray
- Hidden structural damage may exist even after visible repairs
- Long-term reliability and safety is uncertain
- Should be priced at a very significant discount — 40–60% below equivalent clean grade
Buyer advice: RA grade vehicles are high risk. Even if they look and drive fine, airbag deployment in a serious accident can mean hidden structural damage in the floor pan, firewall or A-pillars that repair shops may not have addressed correctly. Only experienced buyers who understand exactly what they are purchasing should consider RA grade cars.

Interior Grades — A, B, C, D
Every Japanese auction sheet carries a second grade for the interior condition, shown as a letter from A to D. This grade is independent of the exterior grade — a car can be Grade 5 exterior with a B interior, or Grade 4 exterior with an A interior.
When evaluating a car, always check both grades together. A Grade 5 exterior with a C interior suggests the car was used hard inside despite being kept clean outside — possibly a commercial vehicle or taxi. A Grade 4 exterior with an A interior is common on older cars that were garaged and well maintained but accumulated minor exterior marks over time.
How Grades Affect Price
The grade directly affects auction price. Here is a typical price range for a Toyota Aqua (2018 model year) at Japanese auction to illustrate how grade affects cost:
| Grade | Typical Auction Price (JPY) | USD Estimate | vs Grade 5 |
|---|---|---|---|
| Grade 6 | ¥1,200,000–¥1,600,000 | $8,000–$10,700 | +25–35% |
| Grade 5 | ¥900,000–¥1,200,000 | $6,000–$8,000 | Baseline |
| Grade 4.5 | ¥750,000–¥1,000,000 | $5,000–$6,700 | −15–20% |
| Grade 4 | ¥600,000–¥850,000 | $4,000–$5,700 | −25–35% |
| Grade 3.5 | ¥450,000–¥700,000 | $3,000–$4,700 | −40–50% |
| Grade R | ¥350,000–¥600,000 | $2,300–$4,000 | −45–55% |
| Grade RA | ¥200,000–¥450,000 | $1,300–$3,000 | −60–70% |

Does Grade Inflation Exist?
One important question many buyers ask is whether the grades can be inflated or manipulated. The short answer is: rarely, but it does happen at some auction houses.
The major auction houses — USS, TAU, LAA, JU — have strict standardised grading systems with professional inspectors and quality control processes. Their grades are highly reliable. Smaller regional auction houses may have less consistent grading standards, and some have a reputation for slightly lenient grades to attract more sellers.
The safeguard is always the damage diagram. Even if the headline grade number seems slightly generous, the actual damage marks on the diagram cannot lie — every scratch and dent must be marked. A car graded 4 at a lenient auction house may have a damage diagram that actually looks more like a 3.5 at a stricter house. This is why you should always read the full auction sheet, not just the grade number.
Key insight: Never buy based on a grade number alone — always read the damage diagram. Two cars both graded 4 can have very different actual conditions depending on where and what type of damage is recorded.
Which Grade Should You Target?
The right grade depends on your budget, intended use and how much you value cosmetic condition:
- Grade 5 or 4.5 — the standard recommendation for private buyers importing for personal use. Best long-term reliability and resale value.
- Grade 4 — acceptable for budget-conscious buyers who understand what they are buying. Read the damage diagram carefully.
- Grade 3.5 or 3 — only for experienced buyers with full knowledge of what the damage diagram shows. Good for buyers who plan to repair or for commercial use.
- Grade R — only if priced significantly below equivalent clean-grade cars and you have reviewed the full repair documentation on the sheet.
- Grade RA — not recommended for most buyers. High structural risk that is difficult to assess without physical inspection.
- Grade 2 or 1 — parts or project cars only. Not worth importing.
Pro tip: For buyers importing to Pakistan, UAE, Kenya or New Zealand — target Grade 4.5 minimum. The cost of shipping, duty and clearance means you want a car that will last and hold its value. The extra money you spend on Grade 4.5 versus Grade 3.5 is almost always recovered in lower maintenance costs and better resale price at your destination.
Always Verify the Auction Sheet
A grade number is only as useful as the full auction sheet behind it. Sellers, dealers and importers can and do misrepresent grades — claiming Grade 4 when the sheet shows RA, or showing a different car's auction sheet entirely for a vehicle that has no auction record. The only way to be certain is to verify the auction sheet directly from the Japanese auction database using the chassis number.
JP Sheet retrieves the original record directly from the auction house database — not from a third party or reseller — and gives you the complete sheet including the damage diagram, inspector notes, mileage, auction price and all photos.
