Even white guys would never be able to assimilate with them. You are never Japanese even if you are half, even when you born in Japan move to overseas and come back to Japan — you are treated as an outsider.
I think that is because you can't really compare a country that's for the most part populated with it's natives (at least for the last centuries) versus a country that basically removed it's natives and was populated from the beginning with people from different nations (like the USA, Australia or Canada).
Immigration works differently when you integrate into a country that's made out of immigrants. Versus a country where the natives are still living there as a majority.
That's not exactly true. They're fine with you being their temporarily, even for a few years. Try to raise a family there and that consideration goes away.
That's exactly what I've been doing for about 20 years as a matter of fact. No real trouble whatsoever myself, but I can't even count the number of times now I've seen people give my Chinese wife shit and then fumble all over themselves when I (an American) walk up and introduce myself. One old guy at a ramen shop even had the balls to try to explain how much better western and Japanese girls are, while she was sitting right next to me.
Question: but how can they tell she's not Japanese (I'm assuming she speaks Japanese)? E.g. many Europeans could pass as being from anywhere in the Americas+Europe as long as they don't say anything and dress like a local. Are they that sensitive to facial structure differences?
What? Are you really saying you couldn't tell if someone is from Spain or Russia? Germany or UK? Hair colour, eyes colour, skin colour, height, facial features are all completely different. Try finding blonde, 1.9m tall Spaniard with blue eyes for example. There are exceptions obviously, but 99% of the time you can easily spot a Brit/German/Polish/Russian in Spain. The same is true for Asia. I'm sure it's very easy for them to tell Japanese/Chinese/Korans/Indians apart.
Sure, the percentages of certain traits in the population are radically different, but there is always enough variation within the population that you can find combinations without automatically having to conclude that the person is foreign. Maybe the variation is smaller within Japan, I know it's larger in China, so maybe a Japanese woman would blend easier in China than the reverse?
I can only judge from media and people i met here in Europe, but for all of them the facial structure is pretty distinct between chinese and japanese people.
This would be after she's introduced herself, but you can make a pretty good guess about most Asian people once you get used to the differences as well
I'm raising a family here in Japan. Pick them up from daycare, take them to the clinic when sick, go to bars, talk to cabbies. Never had a hint of negativity about it.
Sure there's xenophobia in Japan, lots of it, but I've never seen this meme of "they love tourists but when they hate it when you move there!" that people (who mostly have not lived in Japan) repeat online.
If anything, the examples of racism I see are the opposite - they dislike tourists who barge into small corner bars and violate local manners, but if you live there, speak the language and show an understanding of the customs they're fine with you.
