Help with my thesis: Can you tell me about some of the social problems of japanese culture?

Hello! For a little bit of context, right now im working on my degree thesis, it is about the social critique and how its visually presented in media. One of the objectives requires that i get stories and testimonies of people around the world, mainly about the social problems in their respective cultures (and a friend said that i should ask in reddit.)

I´ve made some research on the japanese social problems and, even if i have some info about them, it would be helpful if the natives or foreigners who have lived there for a while could tell me about their experiences, how has it affected them and if you could speak in general about some of the social problems in the japanese culture.

I appreciate all the help you could give me and i apologize if maybe the topic is a bit intrusive.

Also, i apologize if my english is a bit broken, its not my first language and im a bit rust with it.
