I've not done Japan yet, but I've been plenty of places that supposedly hate tourists or hate American tourists. I've never had an issue once. I do tend to avoid tourist-heavy spots. I wouldn't walk across the street to take a picture of Mount Fuji abovs a convenience store. Anywhere I am that there is a tourist-heavy site that I want to see, I'm up early and done with all of those by 10am. Typical irritating tourists go when it's crowded. I'll spend the rest of the day way out in some weird places or hiking or something. Then the evenings I rest or I like to find sporting events to go to. Yeah, I've got multiple instances of where I've had someone talk to me and end up asking "You're from Texas, why are you all the way out here?" So yeah, I haven't really planned Japan although it's mostly on the books for early 2026, but when everyone is crowding up some Instagram spot in Tokyo, I'll be off in Sendai or something anyway. (I just picked a town off a rail map, I have no idea where I'd go but that's how I am).

It's simple. Be civilized, be quiet, don't trash places. Who the hell eats while walking? Bleh. You're on vacation take time to eat like a human being.
