How to read a Japanese auction sheet

JDM Auction Service

The auction sheet is the inspector's report on every car at a Japanese dealer auction. Here's what the grades and codes mean.

Buying · November 7, 2026

Every car at a Japanese dealer auction comes with an auction sheet: a one-page inspection report written by the auction house's inspectors. It is in Japanese, and it is the most useful thing you'll read before you bid.

The overall grade

Most auction houses use a similar scale. Exact meanings vary a little between auction houses, so we translate each sheet rather than relying on the number alone.

The interior grade

A separate letter, usually A to E, rates the interior. A is excellent, C is average and E is poor.

The damage map

A drawing of the car marks each defect with a letter and a number. The letter says what it is and the number says how big it is, usually from 1 (small) to 3 (large).

The notes

Handwritten notes cover things the boxes miss: aftermarket parts, warning lights, smells, noises and missing items. They are often the most important part of the sheet, and the hardest to read without help.

How we use it

Before you bid, we translate the whole sheet into plain English and tell you what it means for that car. Auction cars are sold as-is, so this is where you decide. Learn about Japan auction import.
