The auction sheet is a condition report, not a history file
Every week thousands of cars roll through Japanese auction houses — USS, TAA, JU, HAA and others. Each gets a sheet: an exterior grade, an interior grade, a mileage reading and a hand-drawn diagram with Japanese notes marking scratches, dents, chips and panel repairs.
That sheet is genuinely useful. It is also widely misunderstood, particularly when a listing claims accident free Japanese import cars or pristine condition JDM imports for sale.
What the grade actually measures
Typical grades run S (as new), 6 (new), 5 (excellent), 4.5, 4 (good), 3.5, 3, 2, 1 (poor or heavily modified). Grades R and RA indicate recorded repair history.
The grade is largely a visual assessment of exterior and interior condition, not a mechanical report. A grade 4 car with 90,000 km can have a worn clutch, a tired turbo or leaking shocks and still score 4. Scales are also not perfectly standardised between auction houses, so a 4 at one is not automatically a 4 at another.
The term that matters most: 修復歴 (shūfukureki)
修復歴 means repair history of the frame or unibody — structural repair. Sheets usually state 修復歴無し (none) or flag the repair in the notes.
Critically, no repair history does not mean the car was never bumped. Bumpers, doors, fenders and bonnets are replaced and repainted all the time in Japan, and cosmetic panel work does not count as shūfukureki. So accident-free in auction-sheet terms means: no recorded structural repair. Damage repaired privately without an insurance claim may never surface on the sheet at all.
What the sheet will not tell you
- Mechanical health. There is no compression test, no transmission check, and usually nothing about the timing belt or chain, clutch, turbo or air conditioning.
- Undercarriage rust. A car from a snowy prefecture can carry salt-related corrosion that a top-down diagram will not show.
- Owner count. Many sheets do not list it. Claims of a single owner low mileage import Japan often come from separate paperwork or the exporter's own checks — ask how it was verified.
- Service records. Dealer servicing in Japan is common but does not always travel with the car.
- Odometer accuracy. The sheet records the reading, not its authenticity. Watch for meter-related notes (メーター交換, meter replaced) and for mileage that does not suit the car's age.
- Previous use. Rental, fleet or driving-school history is not always obvious.
Verifying low mileage properly
Ask for the export certificate. It shows the first registration date, chassis number and the odometer reading at deregistration — the final official record before the car left Japan. If that number is well above the auction sheet figure, walk away.
Then sanity-check the maths. A 2016 car showing 20,000 km implies roughly 2,500 km a year — possible in Japan, but worth scrutiny. Genuine low mileage JDM cars for sale stock normally come with an export certificate that lines up neatly with the sheet.
Low mileage is not automatically better, either. Cars that sat unused for long periods can suffer hardened seals, degraded fluids, flat-spotted tyres and a weak battery.
A practical checklist for overseas buyers
- Get the full sheet translated — the Japanese note legend and body diagram, not just the grade.
- Ask directly whether the sheet shows 修復歴, whether there is an R or RA grade, and whether there are any meter notes.
- Request underbody, engine bay, interior and boot-floor photos before bidding.
- Ask for the export certificate before shipping is booked.
- For older or higher-value cars, commission an independent pre-shipment inspection.
- Ask your exporter how the owner count and mileage were sourced. A straight answer is a good sign.
Auction sheets are one of the strongest tools in the Japanese used-car market. Use them as a visual snapshot, confirm the history with documents, and you will be far less likely to inherit a surprise.
