Japanese Auction Sheet Verification and Reading Guide

To verify a Japanese auction sheet, match the car's full chassis number to the original auction record, then check that the grade, mileage, damage map and photos on that record agree with the copy you were shown and with the car itself. If any of these differ, you have a question to settle before you send money.

For an imported Japanese car, this one page is usually the best record of its life in Japan. US history databases only start tracking a car once it is titled here. The years before that live on Japanese paperwork, and sellers sometimes edit, swap or "tidy up" that paperwork.

You don't need to read Japanese to do this well. You need the right number, the original record and a clear idea of what each box on the sheet means.

Key Takeaways

• Use the full chassis number from the car's plate to pull the original record, and treat any seller copy as unverified until it matches.
• Read the grade together with the damage map and the inspector's handwritten notes, since a high number can sit beside serious repair or rust notes.
• A verified sheet describes the past, so confirm the build date for import rules and get a fresh inspection before you buy.

How Do You Match an Auction Record to the Actual Car?

You match a record to a car by its complete chassis number, then by details only that one car shares: the auction house, sale date, lot number, color, trim and the photos. Get the identifier right first, because every later check depends on it.

Find the Full Chassis Number and Distinguish It From a VIN

Most Japanese domestic-market cars carry a chassis number (also called a frame number) instead of a 17-character VIN. It has two parts: a model code and a serial, written like AGH30-0419969. The model code tells you the vehicle family. The serial identifies the single car.

You need both parts. A model code alone, such as BNR32, describes thousands of cars and won't find one auction sheet.

Collect the number from three places and compare every character:

• The manufacturer plate in the engine bay or on the door jamb
• The export or deregistration certificate
• The seller's listing, invoice and any auction document

A one-character difference points to a typo, a swapped document or a different car. Photograph the plate yourself, or ask for a clear, uncropped photo of it.

If the car is already in the US, it may have a 17-character VIN assigned at titling. Use that for US history reports. For the Japanese auction sheet by chassis number, go back to the original frame number on the plate.

Retrieve the Original Record Rather Than Trusting a Screenshot

A seller's image proves only that an image exists. To check it, you need a second copy pulled independently from the auction data for that chassis number. A fresh copy of the same screenshot tells you nothing new.

Japan auction sheet records come from the big auction groups and venues, including USS, TAA, JU and ARAI. Paid online services and auction-member exporters can search these by chassis number. When you ask anyone to look up a lot, give them the venue, the sale date and the lot number together. Lot numbers repeat across sales, so a lot number by itself can point to the wrong car.

Ask the person retrieving it whether the auction issued an amended sheet or a later condition notice. You want the latest version.

Compare Vehicle Details, Auction Dates, and Photos

Lay the seller's copy next to the original and go field by field:

Field	What to look for
Chassis number	Every character identical
Auction house, date, lot	Same sale on both copies
Model, engine, transmission, color	Match the car in front of you
Grades	Same main, interior and exterior grades
Mileage	Same figure and any notes beside it
Damage map	Same marks in the same places
Inspector notes	Same wording, nothing missing

Then check the auction photos. The wheels, trim, body kit, stickers and distinctive scuffs should match current photos of the car. A blurred or cropped field on the seller copy is a reason to ask for a clearer original. It isn't proof of forgery by itself, but a field that reads differently on the two copies is a serious warning sign.

How Do You Read the Grades, Codes, and Inspector Notes?

You read a Japanese auction sheet by working through four parts: the vehicle details box, the grades, the damage map and the handwritten notes. Each part answers a different question. Layouts and grading rules differ between auction houses, so check the venue's own legend when something looks unfamiliar.

Locate Vehicle Details, Mileage, and Condition Ratings

The top of a Japanese car auction sheet holds the identity details. Expect to find the model, chassis number, registration year, engine size, transmission, color, equipment and mileage.

Two points catch new buyers:

• Registration date and build date differ. The sheet usually shows first registration. That date doesn't prove when the car was built, and US import rules run on build date.
• Mileage is in kilometers. Multiply by 0.621 for miles. A car showing 60,000 km has about 37,000 miles. Some listings quote the kilometer figure as if it were miles.

Look for any mark beside the odometer figure. Inspectors note replaced meters or uncertain distance there. The phrase 走行距離不明 means mileage unknown, so treat the displayed reading as unverified.

The grade boxes sit near the mileage. You'll usually see one main grade and a separate interior grade, and some sheets add an exterior letter grade.

Understand Overall and Interior Grades, Including R and RA

The main auction grade is a quick summary of condition on sale day. Common scales run from S (nearly new) down through 6, 5, 4.5, 4, 3.5 and 3 to 2. Many venues use *** or similar marks for non-runners or badly damaged cars. JDMBUYSELL's guide to reading Japanese auction sheets lists the same grade scale with interior letter grades and damage codes.

Grade	Plain reading
S, 6, 5	Very low use, very clean
4.5	Minor defects, little prep needed
4	Visible defects that need repair
3.5	Larger defects, repair or replacement
3	Major defects, possible mechanical issues
R or 0	Repair history (accident damage repaired)
RA	Lighter repair history, at venues that use it

R and RA are the grades to slow down on. They mean the car has repair history in areas the auction treats as significant, often structural. RA doesn't by itself prove a repair was minor. Ask which parts were affected and read the notes for detail.

Interior grades use letters, commonly A (excellent) through D or E (poor). A strong main grade can sit beside a weak interior grade, so read them separately. Under TAA's definitions, a B interior means several minor defects. It doesn't promise spotless seats.

Decode the Damage Map: A, U, W, S, X, XX, and Numbers

The car outline shows where the inspector found each flaw. A letter gives the type and a number gives the size or severity, with 1 the smallest.

Code	Common meaning
A1–A3	Scratch, small to large
U1–U3	Dent, small to large
B	Dent with scratch
W1–W3	Wavy panel or repair trace
S	Rust
C	Corrosion
P	Paint damage or repaint needed
X	Panel needs replacing
XX	Panel already replaced
Y	Hole or crack

Some auctions use B for dents and U for small pin dents, so letters shift between venues. The number scale has no universal size in centimeters either.

Use each mark to plan a question. For W, ask for a close-up of the repair, since it often signals a repaint. For XX, confirm which panel was replaced and check the notes. For S or C, find out exactly where the rust is and how far it runs. Rust on a fender lip is a cosmetic job, while rust near a frame rail is a structural one.

Translate Inspector Notes Without Losing Important Warnings

The handwritten notes box often carries the most important information on the page. A high grade can't cancel a note about flood damage or a replaced pillar.

Ask for a line-by-line Japanese auction sheet translation, with the original Japanese kept beside the English. A summary like "normal wear" hides detail you need. Ask the translator to flag handwriting they can't read.

Watch for these terms:

Japanese	Meaning
修復歴あり	Repair history present
水没	Submersion or flood damage
下回りサビ / 下廻り錆	Underbody rust
走行距離不明	Mileage unknown
内装汚れ	Interior dirt or soiling
シートシミ	Seat stains

Spellings vary, so read the full phrase for where the problem is. If a note mentions damage that the map doesn't show, ask for a photo of that area before you go further.

What Can Auction History Reveal About Hidden Problems?

A car's auction history shows how its mileage and condition changed each time it sold, which is the best way to catch rolled-back mileage or repairs that disappeared from a later sheet. A single sheet is one snapshot, while several sheets for the same chassis number show you a trend.

Compare Dated Mileage Readings for Possible Odometer Rollback

Build a simple table in date order: each auction sheet, any Japanese inspection or service record, the export certificate, US shipping or title paperwork and the current odometer. The readings should only go up.

Date	Record	Reading
Earliest	First auction sheet	km figure
Later	Second auction sheet	Higher km
Export	Deregistration certificate	Equal or higher
Now	Dashboard	Equal or higher

A reading that rises and then falls is the classic sign of odometer fraud. Ask for documented proof, such as a meter replacement record. A verbal story isn't enough. Japan's Automobile Fair Trade Council runs a mileage-management system built on auction data, which shows how central these records are to tracking distance.

Small gains between the final auction and arrival are normal, from yard moves and loading. A big jump or a drop needs an explanation.

Track Repairs, Structural Damage, and Flood Warnings Across Listings

Compare every sheet for the same car, not just the newest. A car might appear as R grade at one sale and as 4.5 at a later one after a repaint. The repair still happened, and the earlier record is where you'll see it.

Look for these patterns across listings:

• An R, RA or 修復歴あり note that vanishes on a later sheet
• XX or W marks on pillars, rails, inner panels or the trunk floor
• 水没 or water-entry notes anywhere in the history
• A seller copy showing a clean grade while the original shows repair history

Structural damage and flood damage affect safety and resale value far more than scratches. If any sheet records either, plan on an inspector checking welds, panel gaps, corrosion and wiring before you commit.

Know What Auction Records Cannot Prove About Current Condition

Each sheet describes the car on one day, often months or years ago. It isn't a mechanical warranty, and it can't show what happened after the sale.

An auction sheet won't tell you about:

• Damage or repairs after the last auction
• Engine, transmission or electrical faults the inspector didn't note
• Smells, slow leaks and intermittent problems
• Whether a modification was legal or done well

A missing record proves nothing either way. Some cars were sold privately or before auction data was widely stored, and older sales are harder to find. Treat a car with no sheet as having an unresolved history and lean harder on service records and a physical inspection.

Does a Verified Sheet Make a Car Eligible for US Import?

A verified sheet confirms the car's identity and history, while US import eligibility depends on its build date and configuration, which you confirm separately. The frame number links those documents together.

Check the Build Date for the NHTSA 25-Year Exemption

A vehicle that is 25 or more years old, counted from its date of manufacture, is exempt from the Federal Motor Vehicle Safety Standards. NHTSA counts from the month and year of manufacture, so a car becomes eligible on that anniversary.

The auction sheet usually shows the registration date, which can trail the build date by months. Don't rely on it. Check the build date on the vehicle plate or a manufacturer production record matched to the frame number. If the car is close to the 25-year line, wait for confirmed eligibility before you ship. Cars imported early can be refused entry or seized.

Check Original Configuration for the Separate EPA 21-Year Exemption

The EPA rule is separate from the NHTSA rule. The EPA exempts vehicles at least 21 years old only when they remain in original configuration, meaning they haven't been modified from the manufacturer's original design.

This is where the sheet helps. Check the equipment box and the notes for aftermarket parts, engine swaps or emissions changes. A car with a non-original engine can fail the EPA exemption even when it passes the age test. Ask the seller to confirm in writing that the engine and emissions parts are original.

Prepare EPA Form 3520-1 and DOT Form HS-7 for CBP Entry

You enter the car through US Customs and Border Protection (CBP). Two declarations go with it:

• EPA Form 3520-1 covers emissions and the exemption you're claiming.
• DOT Form HS-7 covers safety standards and the 25-year exemption.

Keep the export certificate, bill of sale, bill of lading and verified auction sheet together, with the frame number matching on all of them. After entry, check your own state's titling and emissions rules. Some states, California in particular, add requirements beyond the federal ones.

Match the Record, Read the Notes, and Inspect Before Buying

Good auction sheet verification comes down to a fixed order of steps. First, copy the full chassis number from the car's plate and pull the original record yourself. Compare it field by field with the seller's copy.

Next, read the grade together with the damage map and a full translation of the notes. Give R and RA grades, W and XX marks, and any flood or structural notes the most attention.

Then gather every earlier sheet for the same car. Check that mileage climbs in date order and that the repair history never quietly disappears.

Last, treat the sheet as history. Confirm the build date on the vehicle plate for the 25-year rule, confirm original configuration for the EPA, and book an independent inspection that covers the underbody, suspension, brakes, leaks and signs of water entry. Save the original record, translation and seller answers in one file so you have a paper trail if anything turns up later.

Frequently Asked Questions

Can I verify a Japanese auction sheet online for free?

You can often check for free whether a record exists for a chassis number. Downloading the full original sheet usually costs a fee. Pay only after confirming the search found the right car.

Can a PDF auction sheet prove that the record is genuine?

No. A PDF is just a file, and it can be edited like any image. It becomes useful only when it matches a copy you retrieved independently by chassis number.

What does R mean on a Japanese auction sheet?

R means the car has repair history, usually after accident damage to important or structural parts. Some venues show it as 0 or split it into RA, RB and similar grades. Read the notes to learn exactly what was repaired.

What does A1 mean on a Japanese auction sheet?

A1 marks a small scratch at that spot on the damage map. The letter gives the flaw type and the number gives its size, so A3 is a larger scratch. Exact sizes vary by auction house.

Why might no auction sheet appear for my chassis number?

The car may have been sold privately or outside the auctions a database covers, or the sale may be too old for stored records. Check that you entered the full model code and serial correctly. A missing sheet doesn't show the car is clean.

Can I check a Toyota Prius, Toyota Aqua, Toyota Corolla, or Honda Vezel the same way?

Yes. Toyota, Honda, Nissan, Suzuki and Subaru domestic models all use the same chassis number system, so an auction sheet by chassis number search works for each. Popular cars like the Prius and Aqua often have several past sales on record, which gives you more mileage readings to compare.
