Japanese carmakers do not use a Vehicle Identification Number as is common overseas. Instead, Japan uses a Frame Number—nine to twelve alphanumeric characters identifying model and serial number. For example, Frame Number SV30-0169266 breaks down as "V30" identifying the model as Toyota Camry/Vista x30; "S" identifying the engine (4S-FE), and "0169266" being the serial number of the vehicle. Vehicle make is not identified but slight number variations can identify the carmaker, i.e. Toyota usually uses seven digits for its serial numbers while Nissan uses six. Because a frame number contains far less information than a VIN, JDM vehicles also use a Model Code. As an example, SV30-BTPNK breaks down as "SV30", which means the same as above, and "BTPNK" which designates a set of features incorporated in the vehicle

The "Japanese domestic market" has been growing significantly since the late 90's. Many car enthusiasts are attracted to the JDM in different continents such as North America, Europe, and Asia.
Popular brands include Honda, Subaru, Toyota, Mazda, Mitsubishi Motors and Nissan with iconic cars such as the Honda S2000, Subaru Impreza WRX STI, Mitsubishi Lancer, Mazda RX-7. Mazda MX-5, Nissan 300ZX, Nissan Skyline GT-R, Honda NSX, Honda Integra Type-R, Toyota AE86, Toyota Supra, Nissan 350Z, and Civic Type R.
There is a huge following of JDM cars in Canada due to the 15-year rule now making most of the highly sought after imports legal and importable.
