Being rich, highly educated, low in criminality, low in illegal emigration means that other nations are more willing to welcome you in. Think of who you would welcome into your own home and they map pretty homomorphically to the same set of rules you would set at the national level i.e. probably someone who won't steal your things, is good company, won't break your rules, or overstay their welcome.

Not diplomacy or government action, it simply helps if you are the sort of nation whose travelling supporters volunteer to help clean up their mess in stadiums after their matches in international tournaments. Contrast that with away supporters of other nations (looking at you England :D)

The benefit of Japan, Singapore, South Korea is that they are countries in Asia that have historically been supported by the West.

Practically, it means they enjoy easy access to Europe, North America, as well as Asia with little trouble.

In my view Japan at least is undoubtedly a western nation, at least when it comes to the strength and values of their institutions.

Japan in my view is often a post-western country facing issues that the west have yet to encounter.

Would you have some examples?

aging population, lower birth rate, zero interest policy, QE policy, massive debt, have been thing since 90s-00s
