I've had a few Jap imports in my time MR2 turbo , GT4 etc. All were in exceptional condition and all had been unersealed on their arrival to a dealer. Never had an issue selling them on either, all parts are available and there was never an issue with things getting lost in translation due to a combination of most parts having English print on them somewhere and Google assistance. Haven't had an import for about 12 years now though. Oh, and they all had a high spec on them especially for the price. And the mileage....super low. The only exception i ever found to euro spec being better was on the twin turbo supra where the UK got full leather and bigger brakes plus about 50bhp extra. If i found a good vehicle imported i would not hesitate if the price was right. I always made sure the car was in the country so i could go inspect it first, i've heard a few horror stories from people who imported their own.
