/this is a joke, don't do this.
Tokyo has more international tourists than Rome and is the third city destination in the world.

Tourists spilling over on less prepared and smaller places is the real issue IMHO. Seeking "authenticity" while not being local/integrated understandingly generates friction at scale.
But seanmcdirmid in a sibling comment is likely correct, and I'm possibly wrong.
Going to Spain on the other hand would be tourism. I don't speak Spanish, it's not a neighbouring country, you arrive in an airport, etc.
If an American or a Chinese person goes to Paris I feel they likely have different motivations and itinerary than a Brit, Belgian, etc who is taking the train possibly only for the day.
