Parasite singles

According to Wikipedia:

Many young Japanese adults choose to live with their parents, rather than seek a separate residence, a phenomenon known as parasite singles (パラサイトシングル). A 1998 survey by the Ministry of Health and Welfare indicated that about 60% of single Japanese men and 80% of single women between the ages of 20 and 34 lived with their parents.

That survey was taken almost 10 years ago. I wonder if it's changed any since that time. With the cost of living in Tokyo, I can imagine that the numbers are even higher now.
