Almost nobody who buys a used Japanese car for export ever sees it in person before it ships. They see a handful of photos, a price, and — if their exporter is doing it right — an auction sheet. That single page, filled out in shorthand by an inspector who has never met the buyer and has no reason to flatter the car, is the closest thing to an independent inspection most overseas buyers will ever get. Learning to read it properly is the single highest-leverage skill in buying a Japanese used car sight-unseen.
This guide breaks the sheet down piece by piece: the overall grade, the separate interior grade, the damage diagram and its shorthand, and the handful of warning signs that should make you ask your exporter more questions before you commit. None of it requires Japanese fluency. It requires knowing what the codes actually mean.
What Is a Japanese Auction Sheet, Exactly?
A Japanese auction sheet is a standardized condition report produced by a trained inspector employed by the auction house — not by the seller, and not by the exporter selling you the car. Major auction networks such as USS, TAA, JAA, and ARAI each run their own inspection teams, and a vehicle is inspected once, shortly before it goes up for bidding to licensed dealers and exporters. The sheet records an overall condition grade, a separate interior grade, a basic damage map of the body panels, confirmed mileage, and the fitted equipment.
Because the inspector is paid by the auction house rather than by whoever is trying to sell the car that day, the sheet is meaningfully more reliable than a private seller's own description would be. It is not, however, a full mechanical inspection — it is a structured visual and odometer check, and it should be read alongside clear photos and, where possible, a reputable exporter's own confirmation of the car's history.
The Overall Grade: What S, 6, 4.5, 3, and R Actually Mean
The overall grade is the single number or letter printed largest on the sheet, and it is the first thing most buyers look at. The exact scale varies slightly between auction houses, but the version below is the broadly standard convention used across most major Japanese auctions. Always check the legend printed on the specific sheet you're looking at — a small number of houses shift these bands slightly.
- S — Near-new condition, typically under ~6 months old or extremely low mileage. Expect showroom-level condition, priced accordingly.
- 6 — Excellent condition, essentially no visible defects. Top-tier used condition.
- 5 — Excellent, very light wear consistent with light use. Few if any cosmetic issues.
- 4.5 — Very good, minor blemishes only. A few small marks; strong everyday buy.
- 4 — Good condition, normal wear for a used car. The most common "safe" grade for budget-conscious buyers.
- 3.5 — Average, more noticeable cosmetic wear. May need small cosmetic repair; check the damage diagram.
- 3 — Below average, multiple visible defects. Inspect the damage diagram closely before buying.
- 2 / 1 — Poor condition, heavy wear or multiple defects. Budget/parts-grade buyers only; verify carefully.
- R / RA — Vehicle has a documented repair history, often accident-related. Ask specifically what was repaired and why before buying.
- 0 / R0 — Major structural damage, flood damage, or otherwise compromised. Generally best avoided for road use.
One point worth repeating because it surprises so many first-time buyers: the grade describes physical condition, not mileage. A car can carry a grade 4 or 4.5 with relatively high kilometers if it has been well maintained and shows little visible wear, while a low-mileage car can still grade lower if it has cosmetic damage. Read the grade and the odometer reading as two separate pieces of information, not one.
The Interior Grade: A Second, Separate Score
Most sheets carry a second grade — usually a single letter — for interior condition, scored independently of the exterior. This is easy to miss if you're only looking at the big number, but it matters: a great exterior grade says nothing about whether the seats are stained or the car smells of cigarette smoke.
- A — Clean, like new: no notable stains, damage, or odor.
- B — Light wear or minor dirt consistent with normal use.
- C — Noticeable stains, wear, or odor (commonly flagged for smoke smell).
- D — Heavy staining or damage; expect to budget for cleaning or replacement of seats/carpet.
- E — Severe interior damage.
Reading the Damage Diagram
Below the grades, most sheets include a simple line-drawing of the car from above, marked with letters at the points where the inspector noted something. This is the part that intimidates first-time buyers most, but the core shorthand is short and learnable. Exact letter sets vary slightly by auction house — always check the key printed on the sheet itself — but the following covers the symbols you will see most often.
- A1 / A2 — Scratch: small (A1) or larger/more noticeable (A2).
- U1 / U2 — Dent: small (U1) or larger (U2).
- B1 / B2 — Dent combined with scratch in the same spot — more involved than a plain dent.
- S — Rust.
- C — Corrosion (a separate mark from straightforward rust).
- W — Panel wave or distortion, often a sign the panel has previously been repaired and filled.
- X — Panel or part needs replacing. XX — the panel has already been replaced, which flags prior repair history rather than current damage severity.
- E — Small dent or dimple, lighter than a U-graded dent.
A handful of small A1 scratches scattered around a grade 4 car is normal and rarely worth worrying about. A cluster of W or X marks concentrated on one side of the vehicle is a different story — it can indicate a previous side-impact accident, even on a car that still carries a respectable overall numeric grade. This is exactly why the grade and the diagram should always be read together, never one without the other.
Equipment and Mileage Notes
Around the diagram, sheets typically list the car's fitted equipment using short codes — common ones include AC (air conditioning), PS (power steering), PW (power windows), AW (alloy wheels), SR (sunroof), and AAC (automatic climate control) — along with the number of keys supplied and the confirmed odometer reading. Some sheets explicitly flag if the odometer has been replaced or cannot be verified; treat that flag as a reason to ask direct questions, not as an automatic disqualifier, since meter replacement after a legitimate repair does happen.
Red Flags: When to Ask More Questions Before You Buy
- An R or RA grade without a clear explanation of what was repaired — ask your exporter to find out specifically before you commit.
- A 0 or R0 grade — generally best avoided unless you fully understand and accept the structural risk, and have priced the car accordingly.
- Heavy concentrations of W or X marks on one side or corner of the vehicle, even alongside a decent overall number.
- An odometer flagged as unverifiable with no explanation offered.
- Any sheet your exporter can't or won't walk you through line by line — a reputable exporter should be able to translate and explain every mark on the sheet, not just hand it over.
How This Fits Into Buying Through Japanese Auto World
Japanese Auto World is a directory of verified exporters rather than a single fixed inventory, which means the auction sheet — and an exporter willing to explain it in full — is the common thread across every listing on the platform, regardless of which exporter you ultimately buy from. Once you've found a car whose auction sheet checks out, the next practical question is usually whether that specific vehicle can legally be imported into your country at all. That's a separate question from condition, and it's the one our own "Can I Import This Car to My Country?" tool is built to answer before you commit to a purchase.
Frequently Asked Questions
Is a grade 4 auction car good?
Yes, for most buyers. Grade 4 indicates good, normal used condition with no major issues — it's the most common grade bought by export buyers looking for a reliable, fairly priced car rather than a near-showroom example.
What does R mean on a Japanese auction sheet?
R (sometimes shown as RA) indicates the vehicle has a documented repair history, often following an accident. It is not automatically disqualifying, but you should always ask your exporter exactly what was repaired before buying an R-graded car.
Can I actually trust a Japanese auction sheet?
Generally, yes — it is produced by an independent inspector employed by the auction house, not by the seller, which makes it considerably more reliable than a private seller's own description. It is a structured visual and mileage check, however, not a full mechanical inspection, so pairing it with clear photos and your exporter's own confirmation is good practice.
Are auction grades the same at every Japanese auction house?
Broadly similar, but not identical. USS, TAA, JAA, and other networks use closely related but slightly different scales and damage-diagram shorthand. Always check the legend printed on the specific sheet rather than assuming it matches exactly what's described in any general guide, including this one.
Should I buy a grade 3 or 3.5 car?
It can be a smart budget choice if the defects noted in the damage diagram are purely cosmetic and your exporter can explain them clearly. The grade alone isn't the full story — what's actually marked on the diagram matters more than the number at lower grades.
Sources & further reading: this guide reflects the auction-grading conventions used broadly across major Japanese vehicle auction networks (USS, TAA, JAA, and similar). Auction houses publish their own legends on each sheet, which should always take precedence over general guides.
