The traditional japanese family is also an extended family- a son, his parents, his wife, his children, and his unmarried brothers and sisthers.
They live together in his parents' hom.
But this tradition is changing.
Now most families are nuclear families.
They have new problems.
Most men spend a lot of on the job.
They don't see their families often.
This is difficult.
Many married women feel lonely.
Their husbands are almost never home.
Their children are at school.
Sometimes these women get jobs or join cultural groups.
