Not sure what you want to say here, but yes JDM build quality is better only because they have strict laws and more importantly, implementation in their society.
People are educated and they know their rights, we are an uneducated nation deprived of common sense, local manufacturers only produce feature deprived cars because we buy them. Boycott them today and you'll see better builds and more features in no time.
However, the way few members extra ordinarily exaggerate JDM quality and criticize PKDM vehicles is simply foolishness, what I think is if you crash a JDM vehicle or like most of the JDM cars have CVT transmissions, if there ever is a problem, you are gonna end up in deep crap.
Rarely I've found a mechanic who is fully capable of fixing PKDM vehicles properly, yet our people expect JDMs to NEVER fail and even if they do, the build quality will come into play and the car will fix itself, haha!
