Japan has over 130 licensed car auction houses. The largest is USS, which processes 500,000+ vehicles per year and sets the industry's grading benchmark. All licensed houses use the same JAAI grading system — but strictness varies. USS and manufacturer networks (Toyota's TAU, Honda's HAA) grade most rigorously. A Grade 4.5 at a small regional house may reflect lower actual quality than the same grade at USS.
Key Takeaways
- Japan has 130+ registered auction houses — USS is the largest with 500,000+ vehicles/year across 13+ locations
- All licensed houses follow JAAI standards, so Grade 4.5 means the same condition definition everywhere — but strictness of application varies
- USS and manufacturer networks (TAU, HAA) apply grades most consistently — regional houses can be more generous
- The damage diagram is always more reliable than the grade number alone — especially when comparing across auction houses
- Records from smaller regional auctions and manufacturer networks may not appear in standard databases — manual search can find them
- Auction location matters for cost — Hokkaido vehicles add ¥45,000–65,000 in inland transport vs Tokyo region
Japan has over 130 registered car auction houses — from national networks processing half a million vehicles per year to small regional houses selling a few hundred cars a month. When you see an auction sheet, the auction house name tells you a great deal about the quality of the inspection, the reliability of the grading, and how easily the record can be verified.
This guide covers every major Japanese auction house, what makes each one distinct, how their grading standards compare, and exactly what the auction house name on your sheet means for your import decision.
How Japanese car auctions work
Japanese car auctions are not open to the public — they operate as wholesale markets for licensed dealers, exporters and registered buying agents. Every vehicle goes through the same standardised process:
- Vehicle registered by seller — typically a dealer, leasing company, fleet operator or private seller through a member dealer
- JAAI-certified inspector examines vehicle — physically checks the car, marks every defect on the damage diagram, assigns exterior and interior grades independently
- Auction sheet created — complete condition record with grade, mileage, damage diagram, equipment list, inspector notes and photos uploaded to the database
- Bidding takes place — buyers bid in person at the lane, or remotely via online terminal. Typically 30–90 seconds per car
- Record archived permanently — the auction record is stored in the database indefinitely and can be retrieved by chassis number years later
Key fact: The auction inspector is employed by the auction house — not by the seller or buyer. This independence is why Japanese auction grades are trusted internationally. The inspector has no financial incentive to inflate the grade.
The major Japanese auction houses

USS (Used Car System of Japan) is the undisputed largest auction network in Japan and the most widely recognised internationally. USS operates in Tokyo, Osaka, Nagoya, Fukuoka, Sapporo, Okayama, Kyushu and several other cities, with major locations running weekly or twice-weekly auctions.
Why USS grading is the industry benchmark: USS inspectors undergo additional certification beyond the national JAAI standard. USS grades are the reference point that other houses are measured against. When importing blind, a USS Grade 4.5 carries more predictable quality than the same grade from a smaller house.
Location notes:
- USS Tokyo — largest single auction in Japan by volume. Every Toyota, Honda, Nissan, Mazda and Subaru model. Weekly, every Thursday. USS Prime Corner here for premium stock.
- USS Osaka / Kansai — second largest. Strong in domestic Toyota, Honda, Nissan. Weekly.
- USS Nagoya — Toyota heartland. Strong Toyota and Lexus stock. Weekly.
- USS Fukuoka / Kyushu — compact and kei cars. Twice weekly.
- USS Sapporo / Hokkaido — check S marks carefully. Road salt causes underside rust on Hokkaido vehicles.
Record availability: USS records are in the database within minutes to hours of auction. JP Sheet retrieves USS records automatically.
TAU (Toyota Auto Used cars) and TAA (Toyota Auto Auction) are used interchangeably — both refer to Toyota Motor Corporation's own auction network, operating through Toyota dealerships nationwide. TAU primarily sells Toyota and Lexus vehicles from lease returns and dealership trade-ins.
Why TAU stock tends to be well maintained: Cars entering TAU come from Toyota dealer trade-ins and lease returns — vehicles with documented Toyota service history. Consistent grading also protects Toyota's brand reputation.
Record availability note: TAU historically maintained a more restricted database. Some records appear on standard search; others require manual search. If your chassis shows no result and the auction was TAU, manual search is the right next step.
HAA is Honda Motor Company's auction network, operating through Honda dealerships across Japan. HAA Kobe and HAA Osaka are the most commonly seen on auction sheets for Honda vehicles.
HAA Kobe is significant because Kobe is a major export port. Vehicles sold at HAA Kobe have short inland transport distance, reducing export costs compared to inland auction houses.
JU auctions are operated through the Japan Used Motor Vehicle Dealers Association — a national network of licensed used car dealers. JU has locations in virtually every prefecture: JU Aichi, JU Tokyo, JU Osaka, JU Kanagawa, JU Fukuoka, JU Hokkaido and many more.
Because JU only accepts vehicles from licensed member dealers — not private sellers — stock quality tends to be consistently good. JU Aichi has strong Toyota stock due to proximity to Toyota HQ. JU Kanagawa handles high volumes from the Tokyo metro area.
LAA is one of Japan's major independent auction networks with a strong base in the Kansai region (Osaka/Kobe). LAA handles everything from kei cars to large commercial vehicles and buses. LAA Kansai is one of the largest auction sites in western Japan.
LAA's proximity to Osaka and Kobe ports makes it cost-effective for export. LAA is a good source for commercial vehicles and less common models. Records are well-documented and in the standard database.
CAA is based in Aichi Prefecture — home of Toyota Motor Corporation. The location gives CAA disproportionately high Toyota and Lexus volume compared to other auction houses.
CAA vehicles benefit from proximity to Nagoya Port — one of Japan's largest vehicle export ports. Inland transport costs from CAA are among the lowest in Japan.
BCN is the Nissan-affiliated auction network, operating through Nissan dealerships across Japan — the Nissan equivalent of Toyota's TAU and Honda's HAA. BCN primarily sells Nissan and Infiniti vehicles from dealer trade-ins and lease returns.
BCN sheets follow standard national grading format. Vehicles are typically Nissan-dealer maintained with service history.
JAA is one of Japan's long-established independent auction networks operating nationally. JAA covers all vehicle types from passenger cars to commercial vehicles, and is a common source for variety outside the major manufacturer networks.
JAA records are well-archived and in the standard database. JAA is particularly useful for buyers looking for commercial vehicles, buses or trucks alongside passenger cars.
AUCNET is Japan's major online-only auction platform — no physical lane. Vehicles are inspected at their location and bidding happens entirely online. MIRIVE is a newer digital platform operating on a similar model. Both are increasingly used by dealers who want to sell without transporting a vehicle to a physical auction site.
AUCNET inspection quality is generally good — inspectors are JAAI-certified. Because inspections happen at various locations rather than a centralised facility, some buyers prefer in-lane records for high-value purchases. For standard daily drivers, AUCNET records are fully reliable.

Do all auction houses grade the same?
The core grading system — S, 6, 5, 4.5, 4, 3.5, 3, 2, 1, R, RA — is standardised under JAAI (Japan Auto Appraisal Institute) across all registered auction houses. The damage codes (A, B, U, W, X, XX, Y, S, H, E, P, C) are identical everywhere. Interior grades A–E follow the same definition at every house.
However, the strictness of application varies significantly:
- USS — most consistent and strict. A USS Grade 4.5 is the industry reference standard.
- TAU and HAA — consistent grading protects the brand. Reliable.
- JU prefectural houses — generally good. Strictness can vary slightly between prefectures.
- Smaller regional houses — may grade more generously to attract sellers. A Grade 4 here may reflect 3.5 quality by USS standards.
Practical rule: When you have two cars at the same grade — one from USS and one from a small regional house — always compare the damage diagram directly, not just the grade number. The USS car's grade is more precisely predictable.
How auction location affects your import cost
Where a car was auctioned directly affects the inland transport cost from the auction site to the export port:
| Auction Region | Nearest Export Port | Typical Inland Transport |
|---|---|---|
| Kanto / Tokyo (USS Tokyo, JU Kanagawa) | Yokohama | ¥15,000–¥20,000 |
| Kansai / Osaka (USS Osaka, LAA Kansai, HAA Kobe) | Osaka / Kobe | ¥15,000–¥22,000 |
| Nagoya / Aichi (USS Nagoya, CAA, JU Aichi) | Nagoya | ¥12,000–¥18,000 |
| Kyushu (USS Fukuoka, JU Fukuoka) | Fukuoka / Hakata | ¥20,000–¥35,000 |
| Hokkaido (USS Sapporo, JU Hokkaido) | Tomakomai then ship to Honshu | ¥45,000–¥65,000 |
| Tohoku (various JU houses) | Sendai / Yokohama | ¥30,000–¥50,000 |
Import cost tip: A car at HAA Kobe or LAA Kansai is typically ¥5,000–¥15,000 cheaper to ship than the same car from USS Sapporo, purely due to port distance. Factor this into your total landed cost calculation using the JP Sheet Import Calculator.
Why some auction records are not found
If a chassis number search returns no result, the most common causes are:
- Small regional auction house — not all smaller houses upload to the main database in real time. The record exists but needs a manual search.
- Manufacturer network (TAU, HAA, BCN) — these networks have historically kept more restricted databases. Manual search is often needed.
- Private sale in Japan — if the car was sold dealer-to-dealer or privately without going through a registered auction, no auction record exists.
- Vehicle pre-2005 — digital records from before approximately 2004–2005 may not be in the main database. Physical records may still exist.
- Chassis number typo — Japanese chassis numbers contain both letters and numbers that can look similar (0 vs O, 1 vs I). Verify against the VIN plate photo.
No result does not mean no record. JP Sheet's manual search covers records from smaller archives and manufacturer networks not in the standard database. If the standard search returns nothing, manual search ($35, full refund if nothing found) is the right next step — not the conclusion that no record exists.
