The same can be said in reverse for Japanese people on how they see the Western world: Do they assume the USA is like Hollywood or the UK being like British Television? They perhaps assume that all Americans live in a large home with a white picket fence depicting a nuclear family as if its 1950.
All they talk about US is California or New York since most movies and TV shows use either as their main setting. Is the US in real life similar to Hollywood (everyone having a nice car, big home & white picket fence)? That’s the kind of response from non-Japanese assuming Japan is like anime.


I’ve been to France a couple of times, Paris once.
But it’s not like there were people going around telling people off for not abiding by rules, or people getting frosty looks everywhere. Honestly, only a minority of time was actually interacting with people - most of the time was:
All this to say, I think that there’s a lot more to disappointment with a trip to Paris than just getting etiquette wrong, and relating this to Japanese tourists, I would expect most to pick up on some obvious but unwritten rules quite quickly.
