I'm taking into account of the fact that Israel is literally committing a fucking genocide and all that actively while being funded by the US, but holy fucking shit, do I notice a lot of similarities between the two countries. Hell, I'd personally go as far as to describe modern Japan as the Israel of East Asia. Both are extremely reactionary nations with the Empire's hand so far up their asses like sock puppets
To elaborate, while Japanese people in general tend to be more 'polite' and 'reserved' in nature - especially compared to the barbaric Zionists of Israel that are straight up going mask off with their fascism and hatred towards Arabs, it is still pretty well known that Japanese society as a whole are still rife with racism and xenophobia - especially towards Chinese and Koreans. I genuinely feel that the racial attitudes exhibited by Japanese people are comparable to those of Zionists.
This isn't even to mention another well-known fact - that Japan loves to whitewash their history and brainwash their populace that they did nothing wrong with the Ainus, that they did not commit the most depraved massacres,removeds, and experiments towards countless Chinese, South Asians, and Koreans.
So by combining the two factors, I would be quite confident that had it not been fact that modern Japan is quite literally declawed and defanged, and that China, unlike Palestine, has a powerful standing army and nuclear weapons, poses a real formidable opponent, Japan would have been acting quite similarly to how Israel acts because I'd be sure that Japan would be quite keen to be doing the same shit that Israel is currently doing in Palestine and repeat their past crimes towards other East Asians.
Another reason to hate modern Japan would because their country is literally a cyberpunk dystopia rife with capitalism in every corner, causing high depression and suicide rates, with a declining population.
So yeah, I genuinely feel that Japan deserves far more hate than it gets currently.
Japan is way too isolationist to justify hate. Fucked up stuff happens mostly on the territories they have sovereignty over (except ww2) .
