Kenji has worked in Japanese vehicle auctions since 1998, initially as a floor inspector at USS Tokyo before joining the verification side. He specialises in damage notation — the X, B, U, W, and A codes that describe every scratch, dent, rust patch, and structural repair on an auction sheet. His translations are the gold standard for any buyer trying to understand what a sheet actually says.

Hiroshi spent 12 years as a licensed auction inspector (検査員) at JU auctions before joining JP Sheet. He is the team's authority on auction grading — the S, 5, 4.5, 4, R, RA system that determines a vehicle's overall condition. His deep knowledge of how inspectors assess cars means he can identify when a grade looks inconsistent with the damage recorded, a critical skill for spotting misrepresented vehicles.

Yuki specialises in the equipment and options section of auction sheets — a dense list of Japanese abbreviations that tells you exactly what a car has fitted. From sunroofs and navigation systems to seat heating, LSD differentials, and traction control variants — she decodes every code. She also covers mileage verification and the star-rating system used to assess odometer reliability.

Takeshi's background is in vehicle export compliance — he worked for a major Japanese vehicle exporter for 9 years, dealing directly with JAAI export certificates, customs documentation, and import regulations for markets including Pakistan, Kenya, Sri Lanka, and New Zealand. He writes all JP Sheet content related to buying safely, export certificates, scam identification, and import regulations.

Manabu is responsible for JP Sheet's manual search operations — the service for buyers whose vehicle cannot be found in the live database. With relationships across 500+ auction houses built over two decades, he knows how to locate records that have never been digitised, including private imports, older vehicles, and records from smaller regional auctions. He also writes JP Sheet's content covering auction house specifics.

Rina's expertise is in detecting damage that is intentionally concealed — flood damage, fire damage, accident repairs disguised as cosmetic work, and odometer tampering. She trained as an automotive inspector before transitioning to JP Sheet's analysis team. Her articles on water-damaged cars and hidden damage indicators are among the most-read guides on the site, used by buyers across Pakistan, Kenya, and Sri Lanka before making purchase decisions.
