Japanese stereotypes of European countries

Source, out of curiosity as a long-time foreign resident of Japan?

As a person who is Swiss and has lived a while in Japan, everyone says “Heidi”. I think Heidi/the alps is the biggest stereotype of Switzerland to japanese people, not banking.
- What's "Heidi"? I need to ask my wife about this one. Is the pronunciation like German on this word for reference?
Same here, but I've noticed that, at least from my circle here, people don't know too much about countries in Europe. Not that they really should, I guess. I'm from the Czech Republic, and usually I should point it on a map for people to understand better where it is.

"Love Japan " not represented in France wtf? We consume the most Japan media after the Japan itself :)

France is full of weebs??
- France is full of weeb?
  
  Oh boy you have no idea , we had huge access to manga and anime since before the USA and that influenced a part of our pop culture since the 80s.
- They created the original weeb word in the 1800s, Japonisme
Especially during and just following the bubble economy in Japan, a lot of people would go to France and get completely shocked. They largely went to Paris and we're shocked that it was not romance, fantasy, and love, but regular Parisians. There is a word in japanese パリ病 (Paris sickness) to describe the disillusionment of it all.
For some reason, pretty much nobody knows that except the French, lol. I only know it because of Polandball.
Even ignoring media consumption, we have a ton of deluded Japan stans too
Do you know why that is? I never really thought about that, but as a child, before i knew what anime or manga is, we went to france a lot on vacation. Back then the only anime i knew was heidi and drangonball, and that was before the frieza saga even aired. But there, kids my age had dbz video games, a ton of mangas and anime. I bought some mangas and was blown away to read the story where golu goes super saiyan.

And even now, i deadass wouldn't know where i would buy a manga, but if i cross the french border and go to a normal supermarket, they have a whole isle just manga.
- The biggest tvshow aimed for kids switched from French cartoon to anime because it was cheaper ,so it influenced a lot the kids and our pop culture. That s one big reason , there are surely other factors but I don't know them.

Seeing Poland Ball on this makes me wonder exactly what kind of sample of people they polled. Is this all redditors?

I googled poland ball and immediately thought that that chart is just a reddit sample then

Is "killed jews" really a stereotype of it's true?

It’s just a way of deflecting the subject of Unit ~~271~~ 731.

Edit: They really should have named that something easier to remember, like “Crimes against humanity unit” or something.

Germany's stereotype of Japanese is that they raped straighted through China.

I don't think so tbh. Japan did a lot of horrendous things back then, but it's still not nearly as infamous as Nazi Germany at that time. The only time I hear or see any mention of that is usually when someone praises anything Japanese and the other person wants to show how extremely highly educated they are by noting that Japan did something terrible more than half a century ago.
- America downplayed it because it launched straight into the Cold War alliance propaganda and remembering it would be inconvenient while trying to build alliances against China and Russia.
  
  I don't know what Germany teaches about the invasion of China and the occupation of Korea and the Pacific islands, but I can certainly see why both East and West Germany would teach it in school.
