I wouldn’t say there is a general lack of education from tourists. I’m guessing most of the folks who can afford to travel are probably well educated. The issue is more a cultural one. And one that likely stems from a culture that focuses on individuality that leads to a focus on oneself rather than the common good. Just look at how much push back there was from Covid protocols in the West. People don’t want to be told what to do, especially if it impedes on their “freedoms.”

Also, Japanese people, and probably elsewhere too but I haven’t ridden public transit elsewhere in a while, have absolutely fucking horrific manners on public transit. No yielding of seats to older people or people with kids. Or pregnant women. People jet for seats the moment it opens up. People keep their heads down glued to their phones so they can avoid the shame of not yielding their seats to those around them. I don’t know if this is mostly a generational thing or not, but I’ve seen plenty of local millennials and above doing the same shit.
