JDM stands for "Japanese Domestic Market." It refers to vehicles and vehicle parts that are designed, built, and sold specifically for Japan's home market, not for export to other countries such as the USA, Europe, or Australia
. A true JDM car must meet two key criteria: it is manufactured entirely in Japan and sold exclusively within Japan
. The term is often used more loosely to describe Japanese-brand cars or export versions, but strictly speaking, JDM applies only to Japan-market models
. JDM cars are popular among enthusiasts due to their unique features, limited availability, and performance capabilities, often offering specifications or technologies not found in export versions
. Examples include models like the Nissan Skyline GT-R and Mazda RX-7 in their Japan-only configurations
. In summary, JDM means Japanese Domestic Market, denoting cars made for and sold exclusively in Japan
