How to make friends.

I have a serious question so please don't delete my post. I am currently a language student, 22M european, been here for 4 months already. Why is it so hard to make friends? I tried everything, from apps to subreddits. I either get responses from people over 30 wanting to hang out but tbh it's weird to have that big of an age difference friendship so I rather find other people around my age. I thought going to a school would make getting friends much easier but almost everyone ( 99% of the students ) either don't speak english at all or speak broken english and get emberrased and would rather not talk at all. I know it's a school where you learn japanese and some people might say to use it with them instead of speaking english but knowing only easy words, you can't really express yourself. I got some recommendations to use Meetup app but the only events I saw were language exchanges where 30+ japanese people come to train their english and mostly tourists come there for the experience. Since I came here I didn't get to hug someone properly. I kinda tried to hug some people but I swear, it's not me, people don't know how to hug? They either feel awkward or try to touch as little body as possible. I am not the type of zero social anxiety that i can just go in a bar and make friends there. I actually don't know what to do at this point, it's getting to me, the loneliness, the thought that I'm currently wasting my 20s.
