Many Americans continue to travel the world freely, but rising cultural tensions, political divides, and increasing reports of disrespectful tourist behavior are prompting some countries to rethink their welcome.

While U.S. travelers aren’t banned outright, 16 destinations are making it clear: those who ignore local customs may find themselves less welcome. The message is consistent across borders—show respect, or reconsider your trip.

In South Korea and Japan, deeply rooted traditions and social expectations are being overlooked by some visitors. In South Korea, disregard for etiquette and elders creates friction, while in Japan, noisy, disrespectful behavior—especially at shrines and in Kyoto’s geisha districts—has led to access restrictions. Both nations urge tourists to embrace humility and quiet respect.
