It used to be the case, now the majority of the people in high-income countries and the high earners of medium-income countries can globe trot, it is a massive increase.

As for the "colonial" aspect, Japan is not exactly a poor country. It is, in fact, a rather expensive destination (a bit less now because the Yen is cheap) and you will certainly not be seen as an aristocratic elite. You will be respected as a guest because that's how Japan works, but there is a line and it will become very clear if you ever attempt to cross it.

I think that "colonial style" tourism is on the decline, simply because the world is developing and what used to be poor countries now do very well by themselves. They will still accept your money though.
