> I mean it is no coincidence Japan is they only country to ever get nuked..... Twice!

That's a terrible thing to say. Maybe people weren't friendly to you because you have a horrible attitude.

Saying that neighbouring countries hate Japan is more or less a cliche. It's like saying neighbouring European countries hate Germany. In fact, Koreans for example commonly go over to Japan for a weekend trip.

I spent half my time in Japan for several years (3 months there, 3 back home), I absolutely _never_ experienced anything like you describe. Even in areas where I was the only foreigner around. Small children would glance an extra time at me, but everybody else treated me exactly as they did treat others. If I looked like I had some problems people would stop and ask. Service in shops was never a problem. And, as someone else already mentioned, Japan is the only place where I would actually leave my PC on the table in Starbucks while visiting the bathroom. And I'll just repeat again that contrary to your Nr. 2 - I was always offered help if I needed it.

And it just may happen that I'll stay in Japan for my retirement. We'll see. In any case I'll go back as soon as, or if, the pandemic situation is over.

YMMV, but I have been living in Japan for the last two and a half years and I experienced the three things he described. Renting a place was particularly difficult.

Aren't you committing the same blunder? Hating all people of a country, because some of them hate you?
