Japanese last name

[Muz1234]

Are Japanese last name same from a heritage to another heritage? If a Japanese women surname example name Hamasaki marries a man with surname Tanaka, does it mean the women has to change her surname to Tanaka? What about if a foreigner marries a Japanese, does the women surname has to change to the husband's surname?

The majority of Japanese women (95.9 per cent, according to this article) adopted the family name of their husband, although the Civil Code only stipulates that they have to share the same surname. Therefore, they could choose either the wife's or the husband's family name.

On 13 February 1875 (明治8年) it was officially decreed that all Japanese must adopt surnames. An additional decree from 17 March 1876, mandated that spouses must both keep their original family (maiden) names. It was in the year 1896 that Japan returned to the old civil law that obligated spouses to share the same family name. Article 750 of the revised Civil Code (1947) stipulates that a couple should use either the husband's or the wife's surname.

This issue has become a hot topic:

Japan is the sole country in which husband and wife are legally obliged to use the same surname. This should change.
