It's the basis for the wildly successful and profitable "mental clinic" franchise business. There is one of those ( or two, or three, or four ) in front of every train station in Tokyo. For those who don't know Japan, take a look at a train map of Greater Tokyo and count stations, just for fun. You'll be doing that for a while. Then multiply the number by 2 or 4 to get to the number of "mental clinics".
Those are little more than drug dispensers run by legally authorized pimps with no medical expertise of any kind or a psychiatrist or psychologist anywhere on the premises, but anyone ( and millions do ) can "treat" their anxiety, depression, or insomnia, with half a dozen prescriptions a month. For good measure, they make sure to book appointments weekly in both the clinic near home and also the one near work. And maybe have a third one as backup.
What's needed is proper mental health services, on that you're spot on. And as another comment points out, to erase the stigma of suffering a mentall illness, so people don't use alcohol or these vending machine style clinics with no oversight to treat themselves.
That it is a problem and it needs to be treated everyone's perfectly aware of.
