>>17817391hmm when it comes to jap youtube, this is my favourite youtuber
https://www.youtube.com/watch?v=2xAyBI_kuOwI love his videos but also his way of engagement. If you post a comment on any of his videos, he will reply, in the same language as you, within the same day, even on year old videos like the one i linked
All his community posts are in like 20 languages, which are all the languages the people have commented in.
