I saw a documentary on hikikomori once and felt quite sorry for them.
Seeing them just stop taking part in society at the drop of a hat because of the rigours of hard ingrained traditions within Japanese society and there spirit being crushed by just the prospect of failure making them retreat into as small a living space as possible.
Some of the had been like that for over a decade and had no intention of wanting to get back into the society around them.
Living out their self imposed life sentence... sort of a version of the living dead.
Quite harrowing.
Peace.
