Prince Hisahito‘s formal coming-of-age ceremony marked a significant moment for the Japanese Imperial Family, but also served as a stark reminder of the challenges facing the monarchy. The elaborate rituals, held in Tokyo, underscored the dwindling number of male heirs. The 18-year-old prince, a university student with a passion for dragonflies, is currently second in line to the throne.
However, after Hisahito, there are no male heirs, leaving the future of the imperial line uncertain. This situation has reignited the debate surrounding Japan‘s male-only succession law, a policy rooted in the 19th century. While female emperors have existed historically, the current law, largely unchanged since the post-war era, restricts succession to males.
Experts have long criticized this system, arguing that it is unsustainable and relies on outdated practices. They point to a history where concubines were essential for producing male heirs, a practice that ended centuries ago. The popularity of Princess Aiko, the only child of Emperor Naruhito, further highlights the public’s willingness to accept a female emperor. Despite widespread support for Princess Aiko‘s potential succession, the current law prevents it.
The Japanese government has previously attempted to address the succession issue. A proposal to allow female emperors was drafted in 2005, but Hisahito‘s birth shifted the political landscape, and nationalist opposition halted the reform. More recently, a conservative panel recommended maintaining the male-line succession, while suggesting other measures like adopting male descendants from defunct royal families.
The debate remains stalled, largely over the issue of granting royal status to spouses and children of princesses who marry commoners. This impasse leaves Prince Hisahito shouldering the weight of the family’s future, according to former Imperial Household Agency chief Shingo Haketa. He argued that the central question isn’t male versus female succession, but rather how to ensure the monarchy’s survival.
Calls for reform continue, with publications like the conservative Yomiuri Shimbun advocating for changes to the Imperial House Law. They propose granting royal status to princesses’ spouses and children, and allowing female succession, urging the parliament to address this urgent national issue.
Prince Hisahito‘s coming-of-age ceremony included traditional elements, such as receiving a crown from Emperor Naruhito and participating in prayers at the Imperial Palace shrines. He also received the Grand Cordon of the Supreme Order of the Chrysanthemum. These rituals symbolized his transition into adulthood and his future responsibilities as a member of the Imperial Family. The future of the Chrysanthemum Throne, however, remains a subject of ongoing national debate and uncertainty.
