Japan is facing a royal succession challenge that has sparked a nationwide debate. With only three eligible male heirs remaining, many experts and citizens are asking a simple question: Why can’t a woman become Japan’s emperor?
The issue has become more urgent as the country’s imperial family continues to shrink. Although Japan may soon have its first female prime minister, the government is still committed to maintaining a centuries-old rule that allows only male descendants to inherit the Chrysanthemum Throne.
Why Is Japan Facing a Royal Succession Crisis?
Japan’s imperial family now has only three legally eligible male heirs.
- Emperor Naruhito has one child, Princess Aiko, but she cannot inherit the throne under current law because she is a woman.
- The other eligible heirs include the emperor’s younger brother, Crown Prince Akishino, his elderly uncle Prince Hitachi, and Akishino’s 19-year-old son, Prince Hisahito.
With such a limited number of successors, concerns are growing about the long-term future of the world’s oldest hereditary monarchy.
Why Can’t Women Become Emperor?
Japan’s current Imperial House Law, introduced during the Meiji Era in 1889, officially limits succession to male members of the imperial family.
However, historians point out that Japan has had eight female emperors in its history, mostly serving when male heirs were too young to rule.
Professor Makoto Okawa of Chuo University argues there is no logical or constitutional reason to permanently prevent women from becoming emperor. According to him, excluding women from succession reflects outdated gender discrimination rather than historical tradition.
What Does the Government Want?
Instead of allowing women to inherit the throne, Prime Minister Sanae Takaichi’s government has proposed another solution.
The proposal would:
- Restore members from former royal family branches that lost their royal status after World War II.
- Expand the number of eligible male heirs.
- Allow princesses to remain within the imperial family after marrying commoners so they can continue performing royal duties.
However, their children would still not be allowed to inherit the throne if they are not male descendants under existing succession rules.
The proposal is currently awaiting parliamentary approval.
Why Was the Royal Family Reduced?
Before 1947, Japan’s imperial household included many extended royal branches.
Following World War II, reforms dramatically reduced the size of the royal family to lower public spending. Eleven collateral royal branches were removed from imperial status, and female royals who married commoners were required to leave the family.
As a result, the imperial household gradually became much smaller, creating today’s succession problem.
Public Opinion Is Changing
Many opinion polls indicate that a large number of Japanese citizens support allowing women to become emperor.
Supporters argue that:
- Japan has already had female emperors in the past.
- Many constitutional monarchies, including the United Kingdom, have female monarchs.
- Modern society values gender equality.
Some residents believe it feels outdated that women remain excluded from the country’s highest ceremonial position.
Why Do Some People Oppose Female Succession?
Traditionalists believe the imperial family should continue its unbroken male bloodline, arguing that changing the succession rules could weaken one of Japan’s oldest national traditions.
Supporters of the current system say preserving the male lineage helps maintain stability and historical continuity. They also worry that changing centuries-old customs could divide public opinion.
Will the Succession Problem Be Solved?
Many constitutional experts believe the government’s current proposal offers only a temporary solution.
Even if former royal branches are restored, Japan would still depend on a very small number of male heirs. Scholars argue that unless women are eventually allowed to inherit the throne, the country may continue facing succession challenges in future generations.

Why can’t women become emperor in Japan?
Women cannot become emperor under Japan’s current Imperial House Law, which restricts succession to male descendants of the imperial family. Although Japan has had female emperors in the past, the present law introduced during the Meiji Era does not allow women or their children to inherit the throne.
Conclusion
Japan’s royal succession debate is about more than tradition. It reflects a larger national conversation about history, gender equality, and the future of one of the world’s oldest monarchies.
While the government continues to protect the male-only succession system, many scholars and citizens believe allowing women to inherit the throne could provide a more stable and modern solution. Whether Japan eventually changes its centuries-old rules remains one of the country’s most important constitutional and cultural questions.
