Why I Keep Saying Travel to JAPAN ASAP (youtube.com)
Japan was the country I thought would hold out the longest. I visited both Japan and Thailand an era ago, when there were flip phones in Japan and most people in Thailand didn't have phones or only had pushbutton texting phones. 5 years later Thai culture was gone when I visited and everyone was just head down looking at their phone watching American movies, but Japanese culture was still there. Perhaps Japan can lose its culture, too, though, with the massive movements of the current era. Maybe they'll close off their borders completely again. I could see them doing that, as they are a country capable of grand decision-making and decision-taking.
For people asking if Japan is ‘getting worse,’ Yeah, obviously it is. It coudn't be other, it's a mathematical relationship. It's the top culture, the most demanding, and no other people can uphold it, so the amount of foreign influence it can sustain is very low. Japan withstands foreign people because they are so clashing and because Japanese systems are better when they compare, unlike Thailand which was apparently weak when faced with foreign influences, which I mentioned, but Japan depends on a homogenous upholding of its society and culture by maybe 99% or more percent of the population other it will deteriorate, estimating. People from other countries can't undestand this because their culture is easy to hold up, being much less demanding and involved, and also it has proven very easy for Western populations to be tricked into giving up their culture for fear of being called ‘racists,’ this worked for about 25 years and is now over.
Also, Japan like everywhere will have more and more scams targetting foreigners and businesses catering to foreigners, which are negative.
If they don't protect the country, I suspect I'll visit it as visiting a decayed, falling apart Japan, which maybe would be interesting but not as good.
I also don't think creating special tourist zones or regions would be a solution, because the people living there would have even higher exposure to non-Japanese, and the negative effect would come into the country through them.
Overall, the best option would be a culture test as requirement to enter.
