Manufacturer specification sheets, type-approval publications and industry association registration statistics
Structured extraction with bilingual review; registration statistics loaded monthly
Reference data for the Japanese vehicle parc, where many domestic cars carry a chassis number instead of a 17-character VIN.
Specifications are extracted from manufacturer spec sheets and type-approval publications and reviewed by bilingual analysts; Japanese and English names are delivered for every variant. Chassis-number decoding uses model-code tables maintained by Tsubame and is tested against a reference set of known vehicles. Registration counts come from industry association statistics and are aggregates only: the dataset holds no information about vehicle owners. New variants are added monthly, usually within four weeks of launch.
