Prince Hisahito, the son of Japan’s Crown Prince Akishino, celebrated his 18th birthday on Friday, marking his formal entry into adulthood as a member of Japan’s Imperial family.
His coming of age is a significant moment for the Imperial household, which has ruled Japan for over a millennium but now faces the challenges of an ageing population and shrinking family lines. Hisahito is the first male member of the Imperial family to reach adulthood in 39 years, according to a report by Japan Times. As the nephew of Emperor Naruhito and second in line to the Chrysanthemum Throne, Prince Hisahito’s milestone highlights both tradition and the looming uncertainties surrounding the future of Japan’s monarchy.
A new era for the imperial family
In a statement released by the Imperial Household Agency, Prince Hisahito expressed his eagerness to grow through new experiences. “I hope to learn more through each and every experience, absorbing various aspects and growing through them,” he said.
The young prince also thanked his family, acknowledging his parents and sisters, Mako Komuro—who left the royal family after marriage—and Princess Kako, for their support.
As a third-year student at the University of Tsukuba’s Senior High School at Otsuka in Tokyo, Hisahito voiced his intention to focus on his education. “I want to cherish my remaining time at high school,” he added. While the traditional Coming-of-Age Ceremony is typically held for male members of the Imperial family upon turning 18, Prince Hisahito’s ceremony has been postponed to spring 2025 or later, according to the Imperial Household Agency. The decision was made to allow the prince to complete his high school education without interruption.
The future of the imperial line
Prince Hisahito’s entry into adulthood casts a spotlight on the shrinking male lineage within the 17-member Imperial family, which only includes four men.
The 18-year-old prince’s role as the last apparent heir after his father, Crown Prince Akishino, underscores the succession challenges facing the Chrysanthemum Throne. His uncle, Prince Hitachi, an 88-year-old and childless member of the family, is the only other male successor. Japan’s Imperial House Law, enacted in 1947, restricts succession to male members of the family. Female royals, including Prince Hisahito’s sister Mako Komuro, are required to renounce their royal status if they marry commoners, further shrinking the pool of potential heirs. This rule has raised concerns over the future stability of Japan’s monarchy, as discussions about potential reforms—including allowing female succession—continue to be met with resistance.
A symbolic turning point for Japan
With Prince Hisahito now an adult, the future of Japan’s Imperial family will likely remain a subject of public discourse. His unique position as the last male heir in line brings added scrutiny, as Japan’s monarchy grapples with modern-day challenges while maintaining centuries-old traditions. As Japan navigates these complexities, the world will watch as Prince Hisahito continues his education and prepares for a future that holds both royal responsibilities and profound implications for the country’s ancient institution.
