So you had to explain a whole geopolitical context but it's not complex ? That's also omitting that most of them are like that because "That's how it is here", they're not really racist for any other reasons than the culture being very closed to the outside world in general, it's not really Xenophobia for the sake of it.
I'm done trying to have this debate here personally, seems like you and me could have an interesting conversation but the downvotes and answers I get here clearly show people won't even try to understand the complexity of it, it's easier to deem all the Japanese racists apparently.
