Westernization involves change to an entire peoples culture. Not a few people here and there.
For that lowly medical practitioner to have become Easternized they will have had to adopt an entire Eastern medical ideology and methodology, not just add acupuncture to their services list.
Learning some Japanese does not make you Easternized. If you adopted totally and completely a traditional Japanese lifestyle, clothing, diet, language, medicine, morals, values, etc. and did away with pretty much all things Western…then you might be able consider yourself Easternized.
Get it? Easternization doesn’t exist because the scale for it doesn’t exist. Western cultures are not changing as a whole in the way Eastern cultures are changing as a whole from Westernization.
The idea or concept of Easternization can exist sure. But because in actuality Easternization does not really exist, it is not recognized as a notion, word, occurrence the way Westernization is.
