Its not as if those issues are not portrayed in media either. The disgruntled salary men, the bored/hopeless teenagers, the anxiety about confessing/starting a love relationship, how every foreigner is reduced to a stereotype often as a gag for plausible deniability and of course the dozens(?) of times we've seen JP otakus in anime being portrayed either negatively or as creepy, also the whole NEET issue where the victim blames society and they're mocked for it for being a loser etc.

My point is you have to be a certain type of weeb, that consumes only the most mainstream and samey genres like action/adventure etc to not have noticed at least some of these.

I picked up that Japan was a horrible place to live when I got older and realized wait a second this whole taking the last train home trope is a bit too common for my liking. That and a dozen other things but yeah.
