I only say respectful and not nice because it's hard to get them to be true to you. I lived there for about 3 years and what most people view as being kind is more of them just being polite, which they are more polite than almost any other people. That ain't to say there aren't some truly kind Japanese folks.The old Japanese folk where i live cool… some I see in town cool too. I knew a couple of folks that married Japanese women they were super sweet… even surprised me with a birthday cake one year when I was a young man
There were 2 that i would still run the fade with at my old job though.
Regardless, dude is a dikkhead and he was lucky they ain't treat him how folks would do in the west.
