I mean, Western style SJWisim is already a foreign concept the further east you go, even as shallows in as Eastern Europe. There's even a really big difference between former members of the Communist bloc, Russia and current members of the Russian Federation. Its a completely alien way of thought and (the most common thing of these countries is: Xenophobia). It is basically etched into their culture for basically since its inception.
If you look at anime, even a lot of subtle tropes become achingly common: The superiority of Japan and the central focus is that its culture is super awesome (even among Western settings), Christianity is hilariously viewed as this weird mythological religion (much like we have magical Asian Mysticism, the have magical Christian/Western Mysticism. We both do it.), reincarnation (hence why Isekai is so popular), being a 'man' (even in anime with strong female characters). personal and familial honor, honorifics and respect and blue-balling where there is love between characters but they never fuck. Even in small amounts you see this.
The values of Japan are different from the West. The thing is, Western values have always operated like a pendulum. We kind of swing from progressive to conservative. When the pendulum swings too extreme one way, we grab it and swing it back. So our culture is in a constant shift. Japan's culture and the East's culture has been relatively static. So its kind of hard to capture the zeitgeist of an unchanging culture to one that shifts. And we're pretty much in the middle of a cultural shift as our divide goes wider and wider. Our culture will never stay in one place for long because of the ideology we posses. It isn't stagnant and we're used to upheavals. And we're in the middle of one right now. Despite doom and gloom, progressiveness cannot hold onto culture forever. Its all a matter of how long will it take to shift.
So the real question you should be asking is this: Will SJW culture influence Japan enough for it to fundamentally change it before it crumbles? My answer would be no. There's too much there to change with too little time left. We're already seeing the rise of right wing populism across the Western world. Fundamentally, you have support for progtards going down. LGBT, Black Lives Matter, Troons, Illegal Immigrants...all down across the board. Get woke and go broke happening rapidly. The problem is with each hard shift to the left, the backlash grows more and more, with people saying 'I'm not going to buy this'. And the fact is, most anime is still made for the Japanese. The worry should be appeasing China. And then even that situation can change if Winnie the Pooh is fucked out of power, because he's basically doing what Putin did and centralizing the CCP. If Xi croaks and the other CCP factions start knifing each other in a bid for power, all bets are off.
There's another reason why Japan would be a lot harder to succumb to Western-style Woke Leftism and that's the issue of Christianity.
Japan is a fairly secular society but unlike Europe or North America, Christianity never really took root there outside of a few fringe minority communities. The Woke Left helped get a lot of traction thanks to the wider public turning against the austere moralism of Christian conservatism.
In Europe, this happened a lot earlier and has precedents with the French Revolution and Napoleon while World War I and the Bolshevik Revolution more or less blackpilled the Europeans and ultimately led to the demise of a Christian-centered Europe and World War II accelerated that process.
In America, it mainly emerged as a Millennial backlash against the Religious Right that was dominant in the 1980's and 1990's and still a major force in American politics into the 2000's. While the New Left was also a fiercely anti-Christian movement in many respects, it was crushed and the Boomers as a whole tended to either become corporate neoliberals (Yippie to Yuppie) or they were conservative and that led to the rise of the Religious Right and the corporate neoconservatives.
The Woke Left of the Millennials and Early Zoomers is firmly rooted in the New Atheism movement and the compromised nature of higher academia, where the remnants of the New Left still managed to survive as the rest of the New Left either died out or sold out by the time Clinton was elected in 1992, if not earlier.
It's possible the Woke Left could gain traction in Japan, but the historical and cultural differences make it a lot more difficult for it to gain traction in the same way it did in the West. If anything, I could see China as the one who'd try to take Woke Leftism and reformulate it to take down Japan economically with any SJW expats being an auxilary element at best.
The problem is also that Japan really, REALLY does not value degrees in the humanities or things that don't fulfill a purpose in society. Which makes it extremely difficult for academia to make a blow in their society. There's also really not much of a tradition of post-modernism in the East because uh, well....it was relatively resistant to it during the 1960s and had different struggles than the West did and it did not evolve out of it. So the history of the two sides of the world is different, as are its cultural moires and values. And the money is not manifesting in the SJW spheres anymore.
Maybe. Its entirely possible. That also depends on China's cohesiveness and whether or not Xi centralizes his power effective enough, or that his purges will leave a lot of weak underlings and people just start coming in with knives and wrecking balls to destroy what he set up. Its hard to predict. Right now I think China's eyes will be on destabilizing the US as much as possible since Trump fucked them hard with trade. So while China might influence it somewhat, the Chinese have much bigger fish to fry.
