'Hikikomori' is the term Japan uses to describe people who shut themselves off from society... but is this just a mental health issue that's disguised?

The Japanese government says there are roughly one million hikikomori, or people who have played no part in society for over six months, and who've locked themselves at home, away from the public. 

One woman describes this period in her life as one of the lowest point in her mid-twenties. "I spent all my waking hours criticising myself... All I did was get up afternoon, eat, excrete, and breathe. I was like a living corpse. I couldn't find the tiniest bit of worth in myself. I thought my life was meaningless."

Hikikomori exists on a spectrum, sometimes so extreme that the condition becomes debilitating. Hikikomori also seems to encapsulate forms of OCD. The country is now trying to better understand the condition and provide support for people suffering from this phenomenon. In my opinion, sounds a lot like a mental health concern. Mental health concerns are still wildly considered taboo in countries such as Japan and South Korea. What more can be done to reach these populations?
