How to Read Japanese Auction Sheets

1. Introduction

Japanese car auctions are the primary source of used vehicles exported from Japan to markets worldwide, including Australia. Every vehicle listed at a major Japanese auction undergoes a professional independent inspection before it is offered for sale, with the results recorded on a standardised inspection report known as an auction sheet (オークションシート).

For international buyers — particularly those importing vehicles into Australia under the Specialist and Enthusiast Vehicle Scheme (SEVS) or the 25-Year Rule — the auction sheet is one of the most important documents in the purchasing process. It enables buyers to assess a vehicle’s condition, accident history, interior and exterior defects, and overall grade without physically inspecting the car.

Because auction sheets are written primarily in Japanese and rely on a symbolic diagram system, many international buyers find them difficult to interpret at first. This guide provides a clear, thorough explanation of how auction sheets work, what each grade and symbol means, and how to use this information to make safer, more informed purchasing decisions.

Understanding auction sheets is only one part of the process. For a complete overview of importing vehicles, see our car import service.

2. What Is a Japanese Car Auction Sheet?

A Japanese auction sheet is an inspection report produced by a professional, independent vehicle inspector employed by the auction house. The inspector evaluates each vehicle before it is listed and records a detailed account of its condition. Unlike private sales, major Japanese auction networks — including USS (Used Car System of Japan), TAA (Toyota Auto Auction), JU (Japan Used Motor Vehicle Dealers Association), and HAA (Honda Auto Auction) — conduct these inspections to provide a transparent, standardised assessment to domestic and international bidders alike.

“Before reading the auction sheet, understand the full Japanese car auction buying process.

2.1 Information Typically Contained in an Auction Sheet

While formats vary between auction houses, most sheets contain the following:

• Vehicle identification details — make, model, body type, engine displacement, chassis number (VIN)
• Production month and year — used to calculate the vehicle’s precise age for import eligibility
• Initial registration date in Japan
• Odometer reading — with a flag if mileage is unconfirmed (denoted by #, $, or *)
• Standard equipment list — e.g. PS (power steering), PW (power windows), SR (sunroof), 4WD
• Overall auction grade
• Interior condition grade
• Exterior condition diagram with damage codes
• Inspector’s written comments

The chassis number is particularly important for Australian buyers, as it must match the vehicle identification plate and shipping documents. Any discrepancy is a serious warning sign.

3. The Overall Auction Grade System

The overall auction grade is the single most prominent figure on an auction sheet and provides the inspector’s holistic assessment of the vehicle’s condition. It is important to understand that while the grade provides a useful starting point for narrowing down vehicles, it should never be used in isolation. The inspector’s written notes, the exterior damage diagram, and the interior rating must all be considered together to form an accurate picture.

Grading standards vary slightly between auction houses; a Grade 4 at one auction may differ from a Grade 4 at another. As a general principle, however, the following scale applies across the major auction networks:

⚠️ Important Note on Grade Reliability

Auction sheets note that rust is not always reflected in the overall grade. A vehicle graded 3.5 could have significant rust not mentioned in the diagram, while an R-grade car professionally repaired may drive better than a rough Grade 3. Always read the full sheet — not just the headline number.

4. Interior Condition Rating

Alongside the overall grade, Japanese auction sheets include a separate interior condition rating, typically displayed as a letter grade. This rating covers the condition of the seats, dashboard, carpets, headlining, and general cleanliness, including any odours.

Interior condition is especially important for vehicles intended for passenger transport or resale, as upholstery, carpet, and headlining repairs can be costly. Always pay attention to inspector notes mentioning cigarette smoke, pet odours, or staining, as these may not be immediately obvious from the grade alone.

5. The Exterior Condition Diagram

One of the most distinctive features of a Japanese auction sheet is the vehicle diagram — a top-down or side-view outline of the car on which the inspector marks the location and nature of every visible defect. Understanding this diagram is critical, as it reveals defects that may not be evident from the overall grade.

Inspectors use a standardised system of letter codes combined with a severity number (1, 2, or 3) to describe each defect. A numeral 1 indicates minor or barely visible damage; 2 indicates more visible damage; and 3 indicates significant damage that is clearly apparent. Where a defect is too specific to describe symbolically, the inspector may write additional notes in Japanese alongside the diagram.

5.1 Complete Exterior Damage Code Reference

Note: Tyre tread depth may also be annotated on the wheel positions of the diagram at some auction houses. A number at each wheel position indicates the remaining tread in millimetres. This annotation is not universal across all auctions.

6. Inspector Comments

In addition to the graded diagram, most auction sheets include a section for the inspector’s written observations. These notes are handwritten in Japanese and often contain critical information that cannot be conveyed through the standard coding system alone. This section frequently reveals issues that have a significant bearing on the vehicle’s true condition.

6.1 Common Topics Covered in Inspector Notes

• Engine noises or abnormal sounds — knocking, tapping, or exhaust irregularities
• Oil or fluid leaks
• Smoke from the exhaust
• Transmission or gearbox issues
• Previous accident repairs not fully captured in the diagram
• Interior odours — cigarette smoke, pets, dampness
• Evidence of flooding or water ingress
• Non-standard or aftermarket modifications
• Missing or non-functional equipment

For buyers working through an import specialist or broker, inspector notes should always be professionally translated prior to placing a bid. Digital auction sheets from some networks can be processed through translation tools, but handwritten notes require human interpretation to ensure accuracy.

7. Verifying Auction Sheet Authenticity

Because vehicles frequently pass through multiple brokers or intermediaries between the original auction and the end buyer, ensuring the authenticity of an auction sheet is an important safeguard against misrepresentation.

7.1 Steps to Verify

• Confirm that the chassis number on the auction sheet matches the vehicle identification plate and all shipping documentation
• Check that the auction house name, lot number, and auction date are clearly present and consistent
• Use the auction verification services offered by major networks where available — USS, for example, provides online result history lookup
• Cross-reference the auction sheet with the accompanying photographs from the auction
• Obtain the sheet directly from the auction database through a licensed export agent, rather than via third-party scans or screenshots

Reputable import specialists maintain direct access to auction databases and can provide verified, original auction sheets as part of their service.

8. Common Auction Sheet Red Flags

Certain indicators on an auction sheet should prompt additional caution or may warrant rejecting a vehicle entirely, depending on the buyer’s intended use and budget for remediation.

⛔ High-Risk Indicators

R or RA grade (accident history) • XX codes on structural panels (A, B, or C pillars; floor pan; strut housing) • W codes on multiple adjacent panels (suggests major repair) • S2 or C2 rust and corrosion codes • Odometer unconfirmed (#, $, or *) • Ungraded (***) status • Inspector notes mentioning flooding, frame damage, or engine smoke • Multiple X codes across the vehicle

It is worth noting that not all R or RA-grade vehicles are unsuitable purchases. A professionally repaired minor accident — for example, a single replaced door panel — may result in an RA grade, while the vehicle remains in otherwise excellent condition. Conversely, a Grade 3.5 vehicle with undisclosed corrosion can be far more problematic. The full sheet must always be assessed holistically.

9. How Auction Sheets Support the Australian Import Process

For buyers importing vehicles into Australia, the auction sheet provides a critical layer of due diligence. Under Australia’s vehicle import framework, most Japanese imports arrive via the Specialist and Enthusiast Vehicle Scheme (SEVS) — designed for vehicles that were never officially sold new in Australia — or through the 25-Year Rule, which permits the import of any vehicle manufactured at least 25 years prior to the date of importation.

9.1 Key Australian Compliance Considerations

• SEVS eligibility — the vehicle must appear on the Register of Approved Vehicles (RAV) and meet specific criteria such as a minimum power-to-weight ratio or specialist use classification
• Registered Automotive Workshop (RAW) — all SEVS vehicles must be complied by a federally licensed RAW before they can be registered in any Australian state or territory
• RAW compliance costs typically range from AUD $3,000–$8,000 — depending on the vehicle model, required modifications, and parts availability
• Common compliance modifications include — child restraint anchor points, ADR-compliant lighting and indicators, tyres meeting Australian standards, and updated compliance plates
• The Japan–Australia Economic Partnership Agreement (JAEPA) — means most vehicles manufactured in Japan attract no customs duty, though GST (10%) still applies on the combined cost including freight and insurance
• Typical total import timeline is 30–45 days — including Japan-side preparation, sea freight (2–3 weeks), Australian customs clearance and quarantine (5–10 days), and RAW compliance

Auction sheets play a practical role in the compliance process. A RAW will want to understand the vehicle’s condition prior to taking it on for compliance work, and significant undisclosed damage — such as structural repairs or rust — can affect both the feasibility and cost of compliance. Obtaining a thorough auction sheet review before purchase reduces the risk of surprises at the compliance stage.

10. Working with an Import Specialist

For most Australian buyers, working with an experienced import specialist or licensed export agent in Japan is the most reliable path to a successful purchase. A specialist will typically:

• Source vehicles directly from major auction networks (USS, TAA, HAA, JAA, and others)
• Translate auction sheets and inspector notes in full
• Arrange pre-bid third-party inspections for vehicles graded 3.5 and below
• Verify the chassis number, mileage, and auction authenticity
• Manage the export process including deregistration, export certificate, and asbestos clearance documentation
• Coordinate shipping, customs clearance, and introduction to a suitable RAW for compliance

Glam Groups assists clients throughout this process by reviewing auction sheets, providing professional translation of inspector comments, and evaluating real-world vehicle condition before bids are placed. By combining auction data, condition reports, and compliance knowledge, buyers can significantly reduce the risks associated with sourcing vehicles through Japanese auctions.
