America has this too. It's homelessness. The drug abuse and mental illness makes it worse though. Unlike the comparably docile hikikomori, drug and alcohol use leads to erratic and aggressive behavior and makes accommodations and treatment impossible, hence homelessness.
100% this. I think the reason we see these people homeless in the US is due to the myth of the self-sufficiency. That if you can't succeed or fit in it's because you are deficient in some way. It makes it hard to ask for help and it's doubly so if you are introverted to this extreme.
Homelessness is the scariest thing for me. And actually I know that in many cases you became one without your actual influence on it. This problem breaks my heart.
