How to Read and Decode a Japanese Auction Sheet: The Ultimate Guide

A Japanese auction sheet is a vehicle's medical record. Here is how to decode the Japanese symbols and inspection maps to spot hidden repairs and odometer rollbacks.

Almost every Japanese used car imported into Kenya was sourced through a major Japanese auction house. During the intake process, an independent, certified inspector evaluates the vehicle and generates an official inspection sheet. This sheet acts as the vehicle's true medical record, detailing its exact physical condition, mechanical health, and history. However, because these documents are written in Japanese shorthand and use specific codes, they are opaque to the average buyer. Learning to decode these sheets is your single best shield against buying odometer-rolled or accident-repaired vehicles.

Understanding the Overall Auction Grade

The overall grade is located in the top-right corner of the sheet. It ranges from a perfect 'S' to a salvaged '0' or 'R'.

  • Grade S / 6: Brand new. Delivery mileage only (typically under 100 km).
  • Grade 5: As close to new as possible. Pristine paint and interior.
  • Grade 4.5: Excellent. Very light wear, may have tiny paint chips.
  • Grade 4: Good overall condition. Normal wear for age, minor scratches or small dents.
  • Grade 3.5: Average. Clear signs of wear, may require light body reconditioning.
  • Grade 3: Poor. Major scratches, noticeable interior wear, potential mechanical faults.
  • Grade R / RA: ACCIDENT REPAIRED. The vehicle has had structural or frame repairs.
  • Grade XX: Salvage or unmodified damaged vehicle.

Decoding the Body Diagram Map

The auction sheet contains a stylized schematic diagram showing the car's body panels. Inspectors mark this diagram with letters and numbers to indicate the location and severity of damage. The numbers (1 to 4) indicate severity: 1 is minor, 4 is severe.

  1. 01A (Scratch): A1 (tiny scratch), A2 (noticeable scratch), A3 (deep scratch requiring painting).
  2. 02U (Dent): U1 (pin-dent), U2 (medium dent), U3 (large dent).
  3. 03W (Wavy / Repainted Panel): W1 (expert repaint, hard to see), W2 (visible repaint), W3 (poor paint match or visible orange peel).
  4. 04S (Rust): S1 (surface rust), S2 (rust bubbles), S3 (severe structural corrosion).
  5. 05C (Corrosion): Indicates advanced metal rot, usually on the underbody.
  6. 06X (Replacement Required): Panel is heavily damaged and must be replaced.
  7. 07XX (Replaced Panel): The fender, door, or bonnet has already been replaced.

The Odometer 'Mileage' Verification

Check the mileage section on the sheet. If you see a small symbol next to the mileage reading, it is a critical signal:

  • No Symbol: Verified mileage. The digital logs in Japan match the car's cluster.
  • Dollar Sign ($) or Asterisk (*): The mileage is unverified, indicating a suspected odometer rollback.
  • Hash (#): The odometer has been physically replaced, and the actual total mileage is unknown.

Pro Tip: Inspect the Inspector's Notes

The Japanese text area in the middle of the sheet contains the inspector's detailed notes. This is where they note engine noises, active warning lights, exhaust smoke, or underbody structural repairs. Always use Google Lens or a translator service to read these notes before bidding.

— Frequently Asked

Quick answers

Can a Grade R (Accident Repaired) vehicle be imported into Kenya?

+

Yes. KEBS allows Grade R vehicles as long as they pass the QISJ mechanical safety and alignment inspections. However, these vehicles should be priced significantly lower than Grade 4 or 4.5 equivalents.

Are printed auction sheets in Kenyan yards reliable?

+

No. Photoshop alteration of auction sheets is a common scam in Nairobi (turning a Grade R into a Grade 4.5). Always verify the chassis number independently through an online Japanese auction database.
