a term that describes STOCK honda automobiles, that are manufactured for consumers in Japan.

Ricers in the united states believe that by having these stock parts on their cars it makes them so much better, when the money could be better spent on other aspects of modifying ones automobile. Super ricers claim that aftermarket parts manufactured in japan are considered JDM, but that is nonsence because they are MARKETED to united states consumers.
"you see that RHD civic over there? I wonder if its JDM or a USDM car that has been converted"
