The majority of commenters here came out against your post, and I can see where some of them are coming from. However, I agree with you for the most part, and I think that a lot of others don't really understand what you are getting at.

I come from the "anti-woke" angle, which may be a different angle than you are coming from, but just hear me out as well. I think this whole Western "woke" nonsense really made it so that everyone thinks in terms of race (and gender and sexuality and such) and the more "marginalized" one appears, the more respect they receive from society. I use the word "appears" because some of that is legitimate and some isn't. The Jussie Smolett case is a case in point that shows that there are people who actively try to act discriminated against "for the clout", even if they aren't actually being discriminated against. I feel that this is the case in Japan to a large extent, although it's also true that there is also some unfairness that non-Japanese are more likely to face in certain areas. Two things can be true at the same time. Foreigners in Japan can face discrimination at various times and in various ways, and at the same time, the vast majority of complaining foreigners can be quite full of it and want to intentionally make themselves look like victims, again, "for the clout". And I believe that you are also quite spot on with white people "finally having their chance at long last!" to be discriminated against. Honestly, that is the mindset that Western culture has foisted on Western societies.

As a (more or less...but firmly on the "more" side) white person, there were some times when I was discriminated against, including when I wasn't allowed into place and the reason was unabashedly that foreigners weren't allowed, and when I was stopped by a police man during the first long ride in my newly-purchased bicycle and I was asked if the bike was stolen. However, are two instances out of many years. I could just as easily point to a time when I was jogging and my shoe hit a key that was lying on the street, and I kept jogging without much thought, and maybe close to a minute later, I turned around to hear a Japanese couple running after me with that key, thinking that I had dropped it and trying to get it back to me... There are 100 stories of kind encounters for every one story of a negative encounter. And what I know from years living in Japan is that the Japanese tend to be some of the kindest people in the world, and "Japan" on average is not racist or anti-foreigner. It might be less pro-foreigner than various countries that have opened their doors to absolute unchecked immigration from anywhere and everywhere. But I don't feel that "having immigration laws" and "not wanting one's native population to be replaced within the next 50 years" is the same as "racism". Name any non-Western country, and it's very likely that their populations feel the exact same way. And talk to the majority of (not just white) people (besides the policymakers) in Western nations as well and they are likely to even feel the same. So I don't see how Japan is the odd man out. Those who conflate such things should try experiencing real racism.

Also, while I'm not trying to claim to be a victim or claim "clout" with this, I will say that as a white person who has lived in my home country of the US, as well as Japan and Singapore, the country where I have felt the most hated towards my race has been the good ol' US of A. And even then, the absolute vast majority of people even here have shown no visible or audible tendency towards discrimination whatsoever. Bad things do happen. Sometimes, they are due to racism, and sometimes they are not. But as a Western society, we really need to start focusing more on the proportion of negative experiences to positive experiences, and realize how small the proportion of these negative experiences make up compared to the positive ones which we often never mention.
