First of all, we are way more anti-korean than we are anti-chinaman. Although that being said Koreans sneed more about Japs than vice versa. Call Takeshima it's actual name instead of "Dokdo" and REEEEEE ensues. The level of Koreasneed has never died down to the extent that I have met koreans irl in an unrelated country like America and their first reaction when finding out eachothers ethnicities was "oh god please no racism".
I'm waiting for the Japaanese nationalist groups to blame Koreans, somehow. Like how every American crime is "the jews" or "glowies," so is everything "the Koreans" in Japan.
If this mf comes out any other nationality than Japanese that country is done for.
Japan loves stability and thus autocracy tends to happen, but we will rebel if it's nonce. Just not Chinaman level rebel.
However, organized crime is on a really steep decline. Yakuza peaked in the 80s. It's not really good to theorize like this with no proof to impressionable foreigners. What's popular in games and TV isn't the same as what's real.
