Online communities for immersing in Japanese language that AREN’T focused on language learning / exchange?

[This post](https://www.reddit.com/r/LearnJapanese/comments/xvhnf4/learning_while_in_japan_but_surrounded_by_english/) got popular recently and made me realize that I have not been exposing myself to enough native Japanese conversation (in proportion to the native Japanese literature I have been studying with). I already participate in language exchanges, which help my speaking skills but not my comprehension skills (since the native speakers only use English).

Someone in this thread suggested to participate in communities where native speakers gather for reasons other than language learning. I live in a place where there are zero native speakers for quite a few miles, so I was wondering where to find online communities where native Japanese speakers gather. I figure LINE groups, Japanese-language subreddits and Discord servers would be good options, where can I find these communities and are there any more good places to look?
