Those are good points and hence, why I propose that we agree to disagree.
As an example: A Japanese domestic Supra in Japan IS built according to Japan specifications. So essentially any car built by a Japanese automaker and sold in Japan is a Japanese domestic. Regardless of whether an automaker sells their cars to other countries, it still doesn't change the fact the their domestically built cars are built according to Japanese regulations, hence making the domestic versions of the cars, JDM.
It would be like not calling a Viper an American domestic, just because it was sold in another country. Or any other car from any other manufacturer.
Of course, the exception is the 2020 Supra, which is a Toyota-BMW hybrid.
