Japan’s parliament has passed controversial revisions to a law governing who can inherit the throne, a move aimed at addressing the shrinking number of royals by allowing princesses to remain in the imperial family after marriage. The legislation, approved by both houses, enables the adoption of male-line descendants from former branches of the imperial family, though these individuals and the princesses themselves remain barred from the throne. With only one young heir, 19-year-old Prince Hisahito, remaining in the line of succession, the reform seeks to maintain the monarchy’s public duties despite widespread public support for allowing female emperors.
The Mechanics of the Imperial Succession Reform
The newly passed law introduces two primary changes to how the imperial family functions. First, princesses will no longer lose their royal status upon marrying commoners. However, the legislation stipulates they must continue performing royal duties without gaining any right to inherit the throne. Second, the law authorizes the adoption of men from former imperial branches. While these adopted men cannot ascend the throne themselves, their future male offspring would be eligible to succeed the monarch.
According to Seiichiro Noboru, a former diplomat with ties to the imperial family, these complex measures serve a “very clear objective: to prevent the future emergence of a female emperor.” Critics argue that the government is prioritizing a rigid adherence to male-line succession over the practical need for a stable, modern monarchy.
Did you know?
Nearly half of Japan’s 125 emperors were born to concubines. This historical practice was once used as a “safety valve” to ensure the continuation of the male line when infant and maternal mortality rates were high.
Public Opinion Versus Political Tradition
There is a notable divide between the Japanese public and the current government regarding the future of the throne. Polls consistently indicate that 60% to 90% of the Japanese public support the idea of a female emperor. Princess Aiko, the 24-year-old only child of Emperor Naruhito, is a central figure in this conversation. A graduate in Japanese literature who now works for the Japanese Red Cross Society, she frequently draws large, enthusiastic crowds during public appearances.
However, Japan’s first female prime minister, Sanae Takaichi, remains a vocal opponent of changing the male-only rule. During a party convention in April, Takaichi stated, “The unparalleled historic fact that the imperial line has been maintained through the male line for 126 generations is the foundation of the emperor’s authority and legitimacy.”
Historical Context: The 1889 Imperial Household Law
The current male-only succession rule is not an ancient, immutable tradition. It was established by the 1889 Imperial Household Law under the Meiji government. During that era, the state viewed the emperor as the patriarch of a “family-state” and a semi-divine figure. The 1889 laws were also shaped by a civil code that rendered women legally powerless, prohibiting them from owning property or signing contracts without spousal consent.
Historical records show that Japan has had eight female emperors over the past twelve centuries. All were descendants of the male line—specifically the child or grandchild of a male emperor—much like Princess Aiko. Noboru argues that the current government’s refusal to recognize female succession contradicts Article 1 of the Japanese Constitution, which defines the emperor as a symbol of the nation whose position is determined by “the will of the people.”
