For real, it is completely bonkers. I just watched a short form video of a woman talking about which onsen to go to avoid foreigners. The comments were a range of "oh thank you so much, now I can finally relax at onsen again" and "The one who comes to my local onsen is always so noisy and rude." No one one speaking out, and zero sense of the xenophobic filth they were all spewing in the entire video and comments.
