Study Warns: Japan's Future Generations May All Share Last Name "Sato" by 2531 if Marriage Rates Don't Increase

The articles discuss the potential future scenario where all Japanese people may share the same family name, Sato, due to current laws that require married couples to adopt the husband's surname. This issue is of concern as Japan faces a declining marriage rate and population growth. Women's rights advocates are pushing for changes to allow couples to keep their original surnames. If the rules remain unchanged, every Japanese person could bear the surname Sato by the year 2531.
