Undoubtedly true, but there is a mountain of video evidence of Japanese tourists in France and other European towns being awful, loud and unlistening to rules until it causes problems for everyone. From flipping boats to damaging historical sites.

Point is, they aren't "innocent" of the same things they decry other people of doing in their country when they go to other countries. "Gaijin fatigue" is just "thing, Japan" of a problem the world over.
