The law does not say which partner must give up his or her name in marriage. In practice it has almost always been the woman who took the husband’s name. Some women say that is unfair and feel as though their identity is lost.
In traditional marriage, one person, usually the woman, enters the household of the partner and is registered as a member of that household. Men are seen as more powerful in Japanese traditional culture. But as women increasingly have careers, some argue that changing surnames is confusing.
