Some young Japanese men are refusing to leave their bedrooms and are choosing to withdraw themselves from society. The reasons aren't always very clear, but in Japan, it's known as hikikomori.
Hikikomori refers to the act of isolation, and to the young men themselves. The word translates as 'pulling inward' or 'being confined'. Often, a hikikomori's family are both ashamed and at a loss as to how to help their child. Some men have not left their own houses in over a decade!
Isolation and loneliness can have a major impact on our mental health. A scheme called 'Rent-a-sister' in Japan is being used to help these hikkomori men to begin to recovery from their reclusiveness. You can watch more about this here.
