Reminder that this happened, one day Korean decided to randomly get pissed at Japan and boycott all their products, resulting in billions of losses.
Koreans are just as fanatic as Chinese, the situation has become better now for japanese companies in Korea. But there's nothing preventing the next Korean president to go and say "When Japan sends in their people. They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people" and he'd get applauded by the entire nation. And then you'd get shit tons of haters attacking the holo girl.
Japan in active border dispute with Korea doesn't help. While Ayame hate gooks is just a meme, there are reasons why this meme exists.
I'd rather hololive never touch that market unless they are staffed enough to completely prevent another Coco situation.
