Japanese Auction Sheet Abbreviations: The Complete Symbol, Grade & Damage Map Glossary

Why Auction Sheets Are Written in Shorthand

A Japanese auction sheet is not written for export buyers. It is written by a grader, for other Japanese-speaking dealers, under enormous time pressure. A typical grader inspects a car in three to five minutes before it crosses the auction block — there is no time to write full sentences. So the industry settled on a compact visual language decades ago: a single overall number or letter for body condition, a separate letter for interior condition, a small car-outline diagram with one or two-letter codes marking exactly where any damage sits, and a handful of standardized kanji abbreviations for anything that needs a note (repair history, one-owner status, non-smoker, navigation equipment, and so on).

For a Japanese dealer who has read thousands of these sheets, the whole thing takes ten seconds to absorb. For a first-time international buyer, it looks like a code that needs breaking. That is exactly what it is, and that is exactly what this article is for — a single page you can keep open next to any auction sheet and translate it symbol by symbol, without guessing.

Before going further, one clarification that matters more than any individual code: this glossary describes the general, widely-used convention shared across the major Japanese auction networks — USS, TAA, JU, Aucnet and similar. It is not a single universal standard published by one governing body. Grading language evolved independently across auction houses and even between individual graders at the same auction house, so while the codes below are correct for the overwhelming majority of sheets you will encounter, always check the specific legend printed on the sheet or your auction house's own key when a code seems ambiguous. Treat this as your fast, reliable starting reference — not a substitute for the auction house's own documentation.

The Overall Grade Scale: What the Big Number Means

The single most important character on the sheet is the overall grade — usually printed large, in the top corner or center of the form. This grade summarizes the exterior body condition of the vehicle as a whole, and it is the first filter most buyers use before they even look at the rest of the sheet.

Two things trip up new buyers immediately. First, grades like 4.5 are genuinely common — Japanese grading uses half-points between 3 and 5, so "4.5" is not a typo or an unusually specific rating, it is simply the grade between 4 and 5. Second, and more important: R is not a number, it is a flag. A car can be graded "R4.5" — meaning it has a documented accident repair in its history, but the current cosmetic condition is still very good. Buyers who only skim for the numeric grade and ignore the R prefix routinely end up bidding on accident vehicles without realizing it. If your sourcing requirement is strictly accident-free, treat any R grade as an automatic pass regardless of how high the accompanying number is.

This overall grade is a summary judgment, not a substitute for reading the damage map. A grade 4 car with a cluster of dents concentrated on one door reads very differently from a grade 4 car with the same total wear spread evenly and invisibly across the body — and only the damage map tells you which one you are looking at. For a deeper walkthrough of how graders actually arrive at these numbers and the philosophy behind the scale, see our companion piece on Japanese car auction inspection grades explained — that article covers the reasoning behind the grading system in depth, while this one is built to be the fast symbol-by-symbol lookup you keep open while you're actually reading a sheet.

Interior Condition Grades: The Letter Scale

Separate from the exterior body grade, most sheets carry a second, smaller grade for interior condition — usually a single letter. This covers seats, dashboard, headliner, carpet, and general cabin cleanliness and odor (smoke smell in particular is something graders note explicitly).

Note that this A-through-E scale uses the same letters as some of the damage-map codes described below, but the two systems are unrelated — an interior grade of "B" is not the same thing as a "B" mark on the body diagram. Context on the sheet (which field the letter appears in) always tells you which scale is in use, but it is a common source of confusion for first-time readers scanning a sheet quickly. A car with an excellent exterior grade (4.5 or 5) and a weak interior grade (D or E) is not unusual — Japanese owners often drive a vehicle hard from the inside (children, pets, smoking) while keeping the bodywork pristine through careful parking and regular washing. If cabin condition matters for your resale market, do not assume it tracks the exterior grade.

How to Read the Damage Map

Below the grade summary, almost every sheet includes a small line-drawing of the car from above (sometimes with a side profile too), broken into named panels — bonnet, roof, each door, each fender, trunk lid, bumpers, and pillars. This is the damage map, and it is where the single-letter codes appear, each one placed at the specific panel location it describes.

Reading it correctly means doing two things at once: identifying the letter, and noting exactly which panel it sits on. A "C" on the rear bumper and a "C" on the roof rail mean the same type of damage but have very different implications for resale value and repair cost — bumpers are cheap and fast to address, roof panels are not. Buyers who read only the letters and ignore placement are reading half the information the sheet is giving them.

Most sheets also use size or count annotations alongside the letter — a small number or a rough size indicator next to the code — to show how large the mark is. A tiny "A1" style annotation versus a code spanning a wider drawn area on the panel outline tells you whether you're looking at a coin-sized mark or something that covers most of a panel. Get in the habit of looking at the drawing itself, not just tallying letters, because the visual size and spread carries real information the letter alone does not.

Damage Map Symbol Glossary

These are the single-letter codes you will see scattered across the body diagram. This is the most widely used convention across major auction houses, but — and this is worth repeating plainly — exact letter assignments can and do vary between auction houses, and sometimes between individual graders at the same house. Use this as your default reading, and cross-check against the sheet's own printed key whenever one is included.

A few practical notes on using this table. "S" for a repainted or filler-repaired panel is one of the more important codes to understand correctly: it does not automatically mean accident damage — Japanese owners commonly repaint a single door or bumper after a minor parking scrape, which is routine and does not affect the vehicle's mechanical integrity. It is worth noting alongside the R flag, but on its own it is not a red flag. "W" for corrosion deserves real attention, particularly on structural or underbody panels, since rust tends to spread and is expensive to remediate properly — a W mark on a visible cosmetic panel is a different conversation than one near a structural rail or the underbody.

You may also see combined or compound notations on some sheets — for example a code paired with a small number indicating repeated marks of the same type on one panel, or two codes close together on the diagram indicating separate issues on adjoining panels. There is no need to memorize every possible combination; the base letters above cover the overwhelming majority of what you will encounter, and anything unusual is exactly the case where you should default to the sheet's own legend or ask your local buying agent rather than guess.

Common Misreadings That Cost New Buyers Money

The gap between what a sheet actually says and what a new buyer thinks it says is where most bad purchase decisions happen. A few patterns come up again and again.

Treating any letter as a red flag

The single most common mistake: seeing one "A" mark on the damage map and assuming the car is damaged goods. In reality, A is typically the mildest code in the system, marking something as minor as a coin-sized dent or a light scuff. Almost every used vehicle above a grade 3 will carry at least one or two A marks somewhere on the body — that is normal wear, not a defect. What should actually catch your attention is a cluster of marks on one panel, a jump to C, W, or X codes, or an R flag on the overall grade. A lone A is closer to background noise than a warning sign.

Confusing the interior letter grade with damage codes

As covered above, the A-E interior scale and the A/B/C/U/W/X/S damage codes share letters but are unrelated systems living in different fields on the sheet. Buyers scanning quickly sometimes read an interior grade of "C" as a crack somewhere on the car. Always check which section of the sheet a letter is sitting in before interpreting it.

Ignoring panel placement

A B-grade dent on a rear bumper cover is a non-event; the same B-grade dent on a roof panel is a different repair job entirely. Reading letters without cross-referencing where they sit on the diagram gives you an incomplete — sometimes misleading — picture of true repair cost.

Missing the R flag entirely

Because R is attached to the overall grade rather than sitting as its own separate line, buyers focused only on the numeric grade can miss it. "R4.5" and "4.5" look similar at a glance but describe fundamentally different vehicles — one has a documented accident repair history, the other does not.

Assuming codes are identical across every auction house

A buyer who learns the codes at one auction house and assumes they transfer perfectly to another can occasionally misread a sheet. The core letters above are shared broadly enough to be a reliable default, but the specific legend on each sheet is the final authority, especially for less common codes.

Not reading the written notes section

The damage map tells you where and roughly how severe an issue is; it does not always tell you why. The handwritten or typed notes field — covered next — often adds context (cause of a mark, confirmation something was inspected and found sound, mechanical observations) that changes how a code should be interpreted.

Japanese Shorthand and Kanji Terms Glossary

Beyond the grade and damage map, most sheets include a notes section using standardized Japanese shorthand — a mix of kanji, katakana abbreviations, and Roman-letter acronyms borrowed from English. These notes are where graders record ownership history, equipment, and anything that does not fit into the grade or diagram. The terms below are the ones that appear consistently across sheets and are worth learning to recognize on sight.

These terms are not exhaustive — graders occasionally add freehand notes for anything unusual — but this set covers the shorthand you will run into on the large majority of sheets. Two are worth flagging specifically. "実走行" (genuine mileage) is a meaningfully positive note, since odometer tampering is a real concern on older Japanese-market vehicles being exported; its absence does not automatically mean the mileage is false, but its presence is a reassuring confirmation. "不明" (unknown/unconfirmed) attached to mileage should raise your attention and prompt you to weigh the vehicle more conservatively, or ask for additional verification before bidding.

Equipment and Options Abbreviations

Auction sheets also carry a row of equipment abbreviations confirming what the vehicle is fitted with — useful for matching a listing against your buyer's requirements before you commit to bidding.

These equipment codes are far more standardized across auction houses than the damage codes are, since they describe fitted hardware rather than a subjective condition judgment — there is much less room for interpretation in whether a sunroof is present than in how severe a dent is. Even so, treat the equipment list as a starting checklist rather than a guarantee; confirming key equipment through photos or an in-person inspection is worthwhile for any vehicle where a missing feature would be a deal-breaker for your buyer.

Cross-Referencing the Damage Map with the Written Notes

The three parts of the sheet — overall grade, damage map, and written notes — are designed to be read together, not in isolation. The grade gives you a fast summary judgment. The damage map gives you the location and rough severity of specific marks. The notes give you context the map cannot express: why a mark exists, whether something was checked and confirmed sound, or details about mechanical condition that fall outside the body-condition grading entirely.

A practical habit: read the overall grade first to decide if the car clears your basic threshold, then scan the damage map for placement and clustering, then read the notes for anything that changes your interpretation of what you just saw. A cluster of A and B marks concentrated on one rear door plus a note referencing a minor parking incident tells a coherent, low-risk story. The same cluster with no explanatory note, on a vehicle otherwise described as low-mileage and single-owner, is worth a second look or a direct question to your sourcing agent before you commit a bid.

This is also where machine translation genuinely helps and genuinely falls short at the same time. Automated tools are good at converting the kanji shorthand into rough English quickly, which is valuable when you are triaging dozens of sheets a day, but they routinely miss the auction-specific meaning behind terms like grade flags and compact notation, and they cannot judge severity the way an experienced human reader can. Our piece on AI translation for Japanese auction sheets goes into exactly where automated translation earns its keep in this workflow, and where it still needs a human check before you rely on it for a bidding decision.

A Worked Example: Reading a Sheet Line by Line

Put the pieces together with a realistic example. Imagine a sheet for a Toyota Vitz showing: overall grade 4.5, interior grade B, two A marks on the front bumper, one B mark on the rear-left door, an S mark on the rear bumper, equipment codes AC / PS / PW / ETC, and a note reading 記録簿 and 禁煙車.

Reading it in order: the 4.5 overall grade with no R flag means this is a very good condition vehicle with no documented accident history. The B interior grade means the cabin shows light, normal wear — clean but not showroom-new. The two A marks on the front bumper are minor cosmetic scuffs, entirely typical and not a concern for resale in most markets. The single B mark on the rear-left door is a slightly larger dent worth noting in your listing description but not a deal-breaker on its own. The S mark on the rear bumper indicates that panel has been repainted at some point — combined with the absence of an R flag, this reads as a minor prior repair (a small scrape or scuff resolved with a respray) rather than anything structural. The equipment list confirms the vehicle has the basics buyers typically expect. The notes confirm a maintenance record book exists and the vehicle has not been smoked in — both genuinely positive signals.

Put together, this sheet describes a solid, exportable vehicle with normal, explainable wear — exactly the profile most buyers are looking for, and exactly the kind of sheet that a new buyer unfamiliar with the codes might second-guess simply because it has letters on it at all. That gap between what the sheet actually communicates and what an untrained eye assumes it communicates is the whole reason this glossary exists.

Why the Codes Vary Between Auction Houses

It's worth explaining plainly why this article keeps repeating its central caveat. Japan does not have one central regulatory body that issues a single official auction-grading standard used identically by every auction house. USS, TAA, JU, Aucnet and the many smaller regional auctions each operate under their own internal grading manuals, trained their own graders, and evolved their own conventions over decades — conventions that converged heavily around the same core ideas (a numeric body grade, a letter interior grade, single-letter damage codes) because graders move between companies and because buyers demanded consistency, but that were never formally unified into one universal spec.

The practical result is that the codes in this glossary will be correct for the substantial majority of sheets you read, because they represent the common convention that spread across the industry. But individual graders also bring personal habits to how they mark borderline cases, and less common codes in particular can differ from house to house. This is normal and expected in the industry — experienced buying agents build a working knowledge of the specific quirks of the auction houses they use most. The reliable approach for anyone newer to this is: use this glossary as your default reading, check the specific legend printed on the sheet whenever it's included, and ask a local agent or your sourcing partner when a code or combination doesn't fit anything you recognize. Our broader guide on how Japanese car auctions work covers the differences between the major auction houses themselves — schedules, lane formats, and registration requirements — if you're building out sourcing across more than one network.

From Glossary to Bidding Decision

Knowing what the codes mean is only useful if it changes how you bid. A glossary like this one exists to remove ambiguity from the reading process so your actual decision — bid or pass, and at what price — is based on real information rather than a guess or an overreaction to unfamiliar symbols.

In practice, that means building a simple mental checklist you run through every time you open a sheet: check the overall grade and R flag first as your hard filter; scan the damage map for clustering and severity rather than counting individual letters; read the notes for context that changes your read of the map; confirm equipment matches your buyer's requirements; and factor genuine uncertainty (an 不明/unknown mileage note, an unfamiliar code, a sheet with no legend) into your bid price as a discount rather than an automatic pass. Buyers who read sheets this way consistently win better vehicles at fairer prices than buyers who either bid blind on the headline grade or panic-pass on anything with visible letters.

If you're still building this skill, our practical walkthrough on how to buy from Japanese car auctions covers the registration, bidding, and inspection process end to end, with this glossary slotting in as the reference you'd use at the sheet-reading step of that process.

Turning Sheet Data into Sourcing Decisions at Scale

Reading one sheet carefully is manageable. Reading fifty a day, across multiple auction houses, while tracking which vehicles match which buyer's requirements, is a different problem — and it's exactly where manual sheet-reading starts to break down for growing export operations. Sourcing teams that rely purely on individual judgment tend to lose consistency as volume grows: the same grader on your team might read a borderline sheet differently on a busy Thursday than they would on a quiet Monday.

CarDeal365's SmartApp platform is built to close that gap. It captures auction sheet data, damage-map notes, and grading fields directly against each vehicle record, so your sourcing decisions are backed by structured data rather than a sticky note next to a printout. Combined with the automotive CRM built for exporters, every vehicle you win at auction flows straight into inventory with its grade, damage notes, and equipment list attached — ready to match against buyer requirements without re-keying anything. Explore the full platform on the features page, compare plans on the pricing page, or get in touch to talk through your current sourcing workflow.
