 Many young Japanese adults choose to live with their parents, rather than seeking 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.After marriage, the young couple often live in the same house as their parents.
