Many major cities are clamping down hard. Mayors and politicians are under much more pressure from locals to stop their cities turning into, well, Amsterdam. Tourism is fine, but it has increasingly come at the cost of locals.
Well... a moderate amount of tourism is fine, even beneficial; but excessive tourism in any given location becomes a blight. Airbnb has contributed to that, by facilitating short-term profits for "hosts" and the company and ignoring the negative impact.
Tourism that overwhelms the location turns it into a tourist trap; whatever it had before becomes a veneer over the main industry, which will be tourism.
In some places this is incredibly visible (think Las Vegas Strip vs Las Vegas) but you can also see it in many famous tourist destinations.
Of course, large cities like Tokyo are quite resistant to tourism, just because of how big they are - certain areas and attractions may be tourist heavy but the city is still Tokyo.
