I believe that the assertion is Moreso true for Japan than it is for just about any other culture on earth, given their heavy cultural influence and integration into the global economy. I also believe their practices are far more hygenic than those in other non-western States.
It's much harder to pick out the western footprint in Japanese culture because western influences are so heavilly mutated during their transition to Japanese society, and more of them just don't map onto it. The same is harder to say for many other countries that more often emulate than dissect and adapt. Western elements in other societies tend to stick out like sore thumbs, and remain relatively unchanged from their sources.
India is also a good example.
If you include Thailand in countries that have maintained their unique culture free of Western ideas, I think you have to include virtually all countries. I’ve lived around half my life in Thailand, and like any country it has its specialties, but particular resistance to Western ideas is not one of them. It’s a country that has previously prided itself on integration of Western ideals (cf Rama V), and continues to wholeheartedly embrace fusion with certain cultures (Chinese, Western, Japanese) while strongly pushing back on others (Indian, for example).
The same could be said about Indians, Thai or Nigerians.
