Do you think traveling to Japan would slow its globalization? Do you think Japan is not globalized already? I am curious why you think that globalization would hurt Japan (you used the word: ruined).
I think mixing human cultures can be very complex (human social culture is certainly some form of a complex system) and you're correct that it can cause a lot of change and possibly danger like culture getting erased. When cultural integration is done well, it can cause a lot of beautiful things to happen: appreciation and love of the culture(s), sharing the culture, and fusions of culture. Please note: The above is a lot harder said than done.
there is a long list of long-dead languages that attests to this. coca-cola is the number one drink globally because of these kind of implications.
>Do you think traveling to Japan would slow its globalization?
I think the implication is that one should experience it now before it inevitably changes to be more homogeneous with the rest of the world.
I think the two can be the same, however, that does not mean they are the same.
Look up Ainu and Okinawan languages - Japanese is the dominant language that drove its neighbors' cultures to extinct. It has more native speakers than French, German, or Italian. The Japanese culture is not going anywhere.
Most of the time, those "globalization is ruining beautiful Japanese culture" arguments sound like a mixture of orientalism and xenophobic dog-whistle, i.e., "Isn't it nice that there's a country where only its one native ethnic group is considered the true members and all else are at best second-class citizens?"
