newb question!!!
JDM is an acronym for "Japanese Domestic Market"
OEM is an acronym for "Original Equipment Manufacturer"
In theory these would indicate:
"JDM" = something that was stock specifically on the Japanese market version of the car
"OEM" = something that was made by the OEM (Honda) in general (eg: stock parts)
What it usually ends up meaning though is:
"JDM" = ANYTHING a speed shop wants to sell badly, or anything with LEDs
"OEM" = ANYTHING made in China that someone on ebay wants to overcharge for
Hope this clears things up

EDM is european domestic market.
USDM is United States domestic market
Anything on the car when you buy it is OEM (unless it is a used ricer car) regardless of whether it is USDM, JDM, or EDM. Aftermarket honda accessories are OEM parts because they are made by Honda. Anything else is aftermarket.
