If you had enough insight to infer my nationality (which is not even a secret), you should have also inferred that most Koreans have no f---ing reason to have "some East Asian pride reflex" right? You really sounds like some random Westerner who happens to know something about Japan and is desperately trying to overgeneralize that to other Asian countries.

By the way, the same can be said for most Koreans. In fact Koreans don't like Japan so much that there are widespread false beliefs about Japan---say, the social acceptance of the Adult Video industry (which still doesn't exist) or the fabricated reporting of COVID-19 cases (which might or might not have been happened, but if it did happen, was not that excessive as the rumor suggested) or even that there is zero stigma about game centers (there is, but not to the extent you have initially suggested). There are also many true beliefs that I can independently verify from multiple sources, including those about the modern Yakuza. But you seem to believe that the Japanese society is so conglomerated that it can make any such source up to cover its innards and you can only trust insider's accounts (and I do have plenty from my friends in Japan). How am I supposed to rationally continue this discussion given that?
