Japan is running out of royals. So why won’t it let women become emperor?
Japan’s Imperial Dilemma: Why Women Are Barred from the Throne Despite a Shrinking Royal Line
Japan is running out of royals – While Japan potentially prepares to welcome its inaugural female prime minister, efforts to prevent a succession crisis within the imperial household are simultaneously narrowing the possibility of a woman ascending to the Chrysanthemum throne. The imperial family currently possesses only three viable heirs, with two of them already surpassing the age of sixty. This demographic reality has placed the world’s oldest monarchy in a precarious position regarding its future leadership.
A Patriarchal Tradition Under Pressure
For countless centuries, Japan’s monarchy has adhered to a strict male-only line of succession. This custom aligns with the nation’s deeply patriarchal social structure, where men continue to hold predominant positions across various sectors including commerce and governance. However, this longstanding tradition now threatens the very continuity of the imperial institution. In recent decades, the royal family has produced more daughters than sons, creating an unexpected challenge to the male-centric succession model.
To address the shortage of eligible male heirs, government officials have introduced proposals to reinstate former branches of the royal family. This strategy would significantly expand the pool of potential male successors. These legislative changes are currently pending parliamentary approval, yet they have prompted considerable debate among scholars, opposition figures, and ordinary citizens regarding a fundamental question: why not simply permit women to inherit the throne?
Historical Precedents and Legal Barriers
Professor Makoto Okawa, an expert in imperial lineage at Chuo University in Tokyo, has articulated the logical inconsistencies in current policy.
It is difficult to find any rational basis for refusing to allow a woman to become emperor,
he observed. Historical records demonstrate that Japan previously crowned eight empresses, typically during periods when male heirs were too young to assume royal responsibilities. This precedent continued until the Imperial House Law was established in 1889 during the Meiji era, which formally prohibited female emperors from ascending to the throne.
Despite this statutory prohibition, Professor Okawa notes that Japan’s broader constitution does not explicitly prevent women from becoming empress. Furthermore, he argues that excluding women cannot legitimately be characterized as an inherent Japanese tradition.
The idea of excluding women in advance as persons incapable of becoming emperor should be understood plainly as misogyny,
Okawa declared, highlighting the gender bias embedded in the current legal framework.
Public Opinion and Political Resistance
Survey data consistently reveals that the Japanese public remains largely receptive to the concept of female emperors. Kana Sakakura, a Japanese resident, pointed out that European nations like the United Kingdom possess extensive histories of female rulers.
I suppose when you really compare it to other countries, it does feel like Japan still has an atmosphere where women taking on leadership roles in society is avoided,
she remarked, emphasizing the cultural resistance to female leadership.
Nevertheless, the movement for female succession has encountered substantial political headwinds. Prime Minister Sanae Takaichi and her Liberal Democratic Party stand as some of the most vocal opponents to reforming succession laws. During parliamentary deliberations earlier this year, Takaichi maintained that
it was still appropriate to limit eligibility to male descendants of the imperial lineage.
The Shrinking Imperial Household
The government’s proposed amendments, anticipated to become law this month, fail to include any provision allowing a princess to ascend to the throne. Additionally, the children of princesses who marry commoners are also excluded from succession rights—an outcome nearly guaranteed given the royal family’s diminishing size. Though primarily ceremonial, the imperial family serves as a powerful unifying symbol for Japan’s population of 123 million people.
The institution’s significance was underscored by US Army General Douglas MacArthur, who oversaw Japan’s post-World War II reconstruction. According to the US State Department’s Office of the Historian, MacArthur described the emperor in a telegram as
a symbol which unites all Japanese,
adding that
Destroy him and the nation will disintegrate.
Before World War II, succession planning was considerably less complicated. The imperial family was substantially larger and included collateral branches known as Oke, which provided alternative candidates should the primary bloodline fail to produce an heir. Everything transformed in 1947 when Japan, struggling with a devastated economy, amended the Imperial House Law to reduce the imperial family’s size and curtail royal expenditures. This legislation effectively limited imperial membership to immediate relatives of Emperor Hirohito, eliminating eleven collateral branches and establishing the conditions for today’s heir shortage.
The original royal household of 67 members contracted to just 16 individuals, a reduction intensified by the requirement that female members must depart the imperial family upon marrying commoners. The latest governmental proposal aims to permit the imperial family to adopt members of these former collateral branches who are at least fifteen years old, unmarried, and without children. Their offspring would subsequently qualify for the throne.
Currently, Emperor Naruhito, aged sixty-six, has a daughter, the highly beloved Princess Aiko. Legally prohibited from inheriting due to her gender, the twenty-four-year-old princess has no children. Even if she were to have a son, that child would remain ineligible to succeed to the throne under existing regulations.
