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.
How Japanese Car Auctions Work
Before diving into individual auction houses, it helps to understand how the system works. Japanese car auctions are not open to the public — they operate as wholesale markets for licensed car dealers, exporters and registered buying agents. The process for every vehicle is standardised:
- Vehicle registered by seller — typically a dealer, leasing company, fleet operator or private seller through a member dealer
- Inspector examines vehicle — licensed inspector employed by the auction house physically checks the car, marks every defect on the damage diagram, assigns exterior and interior grades
- Auction sheet created — complete record of condition, mileage, grade, photos and notes uploaded to the auction database
- Bidding takes place — buyers bid in person at the lane, or remotely via online terminal. Bidding is fast — typically 30–90 seconds per car
- Record archived — the auction record is archived permanently in the database and can be retrieved by chassis number
This process produces the auction sheet — the permanent condition record that JP Sheet retrieves directly from the auction database.
Key fact: The auction inspector is employed by the auction house, not by the seller or buyer. This independence is what makes Japanese auction grades so trustworthy — unlike dealer assessments, the inspector has no financial incentive to inflate the grade.
The Major Japanese Auction Houses

USS is the undisputed largest auction network in Japan and the most widely recognised name in Japanese used car auctions internationally. USS operates major locations in Tokyo, Osaka, Nagoya, Fukuoka, Sapporo, Kyushu, Okayama and several other cities, with some locations running auctions multiple times per week.
What makes USS grading special: USS is known in the industry for the most rigorous and consistent grading standards in Japan. USS inspectors undergo additional certification beyond the national standard, and USS grades are considered the benchmark that other auction houses aspire to. A USS Grade 4.5 is a reliable, consistent indicator of vehicle condition.
USS locations and what they typically stock:
- USS Tokyo — the largest single auction in Japan by volume. Enormous variety — domestic kei cars to luxury imports. Weekly auction every Thursday.
- USS Osaka / Kansai — second largest USS location. Strong in domestic Toyota, Honda and Nissan stock. Weekly auction.
- USS Nagoya — Toyota heartland. Strong Toyota and Lexus stock. Weekly auction.
- USS Fukuoka / Kyushu — significant volume of compact and kei cars. Twice weekly auctions.
- USS Sapporo / Hokkaido — note that Hokkaido cars may have rust from road salt exposure in winter. Check S marks carefully.
Record availability: USS records are in the standard digital database immediately after auction. JP Sheet retrieves USS records automatically — no manual search needed.
TAU is Toyota Motor Corporation's own auction network, operating through Toyota dealerships across Japan. TAU primarily sells Toyota-branded vehicles — Corolla, Prius, Aqua, Vitz, Hiace, Land Cruiser, Crown and others — that have come off lease or been traded in at Toyota dealerships.
Why TAU vehicles tend to be well maintained: Cars entering TAU auctions typically come from Toyota dealership trade-ins and lease returns. Dealership-maintained vehicles have full service records and tend to be in better condition than private seller vehicles. TAU grades are generally reliable and consistent.
Record availability note: TAU historically maintained a more restricted database compared to USS. Some TAU records appear in the standard database, others may require a manual search depending on the location and year of auction. If your chassis shows no result on standard search and the auction was at a TAU location, manual search is the right next step.
- Toyota Corolla, Prius, Aqua, Vitz are very common at TAU
- Hiace vans and commercial vehicles appear regularly
- Land Cruiser and Lexus models appear at higher-volume TAU locations
HAA is Honda Motor Company's own auction network, operating similarly to Toyota's TAU. HAA primarily sells Honda and Acura vehicles from Honda dealership trade-ins and lease returns across Japan. HAA Kobe and HAA Osaka are the most commonly seen names on auction sheets for Honda vehicles.
HAA uses the standard Japanese auction grading system. Vehicles are typically dealer-maintained and in good condition. The Fit, Vezel, N-Box and Civic are particularly common at HAA auctions — making it a key source for these popular import models.
HAA Kobe is significant because Kobe is a major export port — vehicles sold at HAA Kobe have very short inland transport distance to the port, which reduces export costs compared to vehicles from inland auction houses.
LAA is one of Japan's major independent auction networks with strong presence in the Kansai (Osaka/Kobe) region. LAA handles a wide variety of vehicles from compact kei cars to large commercial vehicles. LAA Kansai is one of the largest auction sites in western Japan.
LAA records are generally well documented and available in the standard database. LAA's strength is volume and variety — buyers looking for less common models or commercial vehicles often find good stock at LAA auctions. LAA Kansai's proximity to Osaka and Kobe ports also makes it cost-effective for export.
JU auctions are operated through the Japan Used Motor Vehicle Dealers Association — a national network of licensed used car dealers. JU auctions focus on vehicles from member dealers, which tend to be well-maintained with full service histories. JU has locations in virtually every prefecture in Japan including JU Aichi, JU Tokyo, JU Osaka, JU Kanagawa and many more.
Because JU only accepts vehicles from licensed member dealers — not private sellers — the average condition of JU auction stock tends to be better than open market auctions. Dealers who want to sell at JU must be registered members, which creates a layer of accountability.
JU prefectural auctions: JU Aichi (near Toyota, strong Toyota stock), JU Kanagawa (Tokyo metro area, high volume), JU Osaka, JU Fukuoka, JU Hokkaido, and dozens more. Each runs on its own schedule — typically weekly or fortnightly.
CAA is based in Aichi Prefecture — the home of Toyota Motor Corporation. Because of its location in Toyota country, CAA handles a disproportionately high volume of Toyota and Lexus vehicles compared to other auction houses. CAA records are well-archived and follow national grading standards.
Cars sold at CAA benefit from proximity to Nagoya Port — one of Japan's major vehicle export ports. Inland transport costs for CAA vehicles are among the lowest in Japan, making them cost-effective for export buyers.
BCN is the Nissan-affiliated auction network, operating through Nissan dealerships across Japan. Like TAU (Toyota) and HAA (Honda), BCN primarily sells Nissan and Infiniti vehicles that have come off Nissan dealership trade-ins and leases. Common models include Note, Serena, X-Trail, Skyline, March and Elgrand.
BCN vehicles are typically dealer-maintained Nissan products with service history. The auction sheets follow standard national grading format. BCN is the Nissan equivalent of TAU (Toyota) and HAA (Honda).
AUCNET is Japan's major online-only auction platform — there is no physical auction lane. Vehicles are inspected at their current location, auction sheets created, and bidding takes place entirely online. AUCNET was one of Japan's first online vehicle auction systems and remains widely used by dealers who want to sell without physically transporting their vehicle to an auction location.
AUCNET inspection quality is generally good — inspectors are certified and follow national standards. However, because inspections happen at various locations rather than at a central facility with standardised lighting and equipment, some buyers prefer in-lane auction records for high-value purchases.

Do All Auction Houses Grade the Same?
The core grading system — grades S, 6, 5, 4.5, 4, 3.5, 3, 2, 1, R, RA — is standardised across all registered Japanese auction houses under JAAI (Japan Auto Appraisal Institute) and national dealer association guidelines. The damage codes (A, B, C, U, W, X, Y, S, H, E, P) are identical at every house.
However, the strictness of application varies between houses:
- USS is known for the most consistent and strict application of grading standards in the industry. A USS Grade 4.5 is highly reliable.
- TAU and HAA (manufacturer networks) are also well-regarded for grading consistency, partly because consistent grading protects the brand reputation of Toyota and Honda.
- Smaller regional houses may apply grades more generously to attract more sellers — a Grade 4 at a small regional house may actually reflect Grade 3.5 quality by USS standards.
Practical advice: When comparing two cars — one from USS and one from a small regional house — at the same grade, the USS car is the safer bet. If both grades are equal on paper but prices differ significantly, the USS car's grade is more reliably predictable.
How Auction Location Affects Your Import Cost
Where a car was auctioned in Japan directly affects the inland transport cost from the auction house to the export port. This is a real cost that your exporter passes on:
| 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 (ship to Honshu first) | ¥45,000–¥65,000 |
| Tohoku (various JU houses) | Sendai / Yokohama | ¥30,000–¥50,000 |
Import cost tip: A car sold at HAA Kobe or LAA Kansai is typically ¥5,000–¥15,000 cheaper to export than the same car sold at USS Sapporo, purely due to port distance. Use the JP Sheet Import Calculator to factor this into your total landed cost estimate.
Why Some Auction Records Are Not Found
If you search a chassis number and get no result, the most common reasons are:
- Small regional auction house — not all smaller houses upload to the main database in real time. Records may exist but require manual search.
- Manufacturer network (TAU, HAA, BCN) — these networks have historically maintained more restricted databases. Some records require manual search.
- Private sale in Japan — if the car was never sold through a registered auction (private dealer sale, company disposal, family transfer), no auction record exists.
- Very old vehicle — auction records from before approximately 2005 may not be in the digital database. Physical records may still exist.
- Chassis number typo — Japanese chassis numbers can look similar. A single incorrect character produces no result. Double-check the chassis from the VIN plate.
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 your standard search returns no result, the manual search option ($35, full refund if nothing found) is the next step — not the conclusion that no record exists.
