Japan has some of the most transparent used car history data in the world. Informed buyers use multiple sources — and are experienced at identifying discrepancies. Proactive disclosure is always the best strategy.
What Buyers Check
- Shaken (車検) history: The vehicle inspection certificate (車検証) records all past inspections with dates and odometer readings. Mileage discrepancies between inspections raise immediate red flags.
- Auction grade history: Japanese used car auctions maintain detailed inspection grade records (USS, CAA, etc.). Buyers use past auction sheets to see documented condition at previous sales.
- JARWA or equivalent vehicle history reports: Third-party history reports aggregate insurance claim data, accident records, and registration history.
- Loan/lien status: Outstanding loans registered against the vehicle prevent the Land Transport Office transfer. Buyers verify this before committing.
- Service records (整備記録簿): Full service book stamps are inspected carefully — gaps in service history are a significant concern.
Disclosing Accident History
Japan has comprehensive accident and insurance claim data. Attempting to hide accidents is counterproductive — buyers or their inspectors will identify repairs. Disclose all incidents proactively; this actually builds trust with serious buyers.
Settle Any Loan Before Listing
If the vehicle is under a loan, the lender's lien must be cleared from the vehicle certificate (車検証) before any transfer. Obtain a lien release and update the certificate — this cannot be done after a buyer has been found without delaying the transaction.
Get an Inspection Grade Before Listing
Consider having your vehicle graded by a Japan auction inspection service before listing privately. A documented grade adds credibility and is particularly valuable for higher-mileage or older vehicles.
