How can i tell if I own a JDM Integra?

I own a 1993 Acura Integra GSR and was told it was a japanese import at the time of purchase. The guy I bought it from told me that the vin started with a J, meaning it was an import. Is this true, or was this guy giving me false information?|||The first letter of the VIN denotes where the car was assembled. So because it starts with a J, yes, it was built in Japan. See the link below for further information on how to read and decode the VIN.|||Yes
