Prince Hisahito turned 20 on Sunday as the University of Tsukuba sophomore faces growing attention as a future monarch in Japan, following the government’s unpopular revision to the Imperial House Law that reinforces male-only succession rules.
Japan’s imperial family finds itself at a generational and legal crossroads. The nephew of Emperor Naruhito is second in line to the 1,500-year-old Chrysanthemum Throne behind his father, Crown Prince Akishino, and remains the youngest of just 16 members in a rapidly shrinking institution according to reporting from Associated Press. While public attention focuses heavily on his academic pursuits and growing roster of royal responsibilities, the legal framework governing his future has sparked intense national debate.
University Life, Academic Rigor, and Public Duties
Prince Hisahito leads a fulfilling life divided between his university commitments in Ibaraki Prefecture and official palace functions as detailed by Jiji Press. As a second-year student of the College of Biological Sciences within the School of Life and Environmental Sciences at the University of Tsukuba, his daily routine involves advanced lab work, compulsory English courses designed to help him read biology papers, physical education classes, and outdoor field studies noted The Japan Times.
Away from his studies, the prince has deepened his lifelong interest in geography and cartography. Footage released by the Imperial Household Agency captured by Tokyo Broadcasting System shows him visiting the Science Museum of Map and Survey in Tsukuba, where he peered through a telescope and calculated latitude.
He has also steadily increased his ceremonial workload. Over the past year, the prince completed his coming-of-age ceremony, attended New Year’s greetings at the Imperial Palace, and participated in a state banquet for visiting Philippine President Ferdinand Marcos Jr. His travels over the past year span six prefectures, including Hokkaido, Mie, Kyoto, Osaka, Nara, and Hiroshima, where he prayed for atomic bombing victims and joined a boy scout event to help prepare breakfast for participants reported The Japan Times.
Crown Prince Akishino Expresses Mixed Feelings on Succession Laws
The milestone birthday arrives in the shadow of major legislative changes pushed through by the conservative government of Prime Minister Sanae Takaichi highlighted by Associated Press. In July, Japan’s parliament enacted a revised Imperial House Law that reinforces male-only succession while lifting a ban on adopting male offspring from extremely distant former royal families.

While acknowledging that he cannot speak freely on political decisions due to his standing as an imperial family member, Akishino added that society needs to keep making progress, and I believe it is important for people with different views to keep thinking what’s best
according to the news agency dispatch. He also noted that I believe there is no difference between men and women
when fulfilling the social duties required of the modern imperial family.
Public Backlash and the Popularity of Princess Aiko
The legislative tightening has provoked widespread public criticism. Citizens and commentators have staged protests, arguing that the patriarchal rules are anachronistic and sexist, and specifically designed to prevent Emperor Naruhito’s 24-year-old daughter, Princess Aiko, from ruling noted Associated Press. Most Japanese want her to be his successor.
Experts point out that the updated legal framework places profound pressure on the young prince and any future spouse to bear a male child to determine the future of the imperial family.
Future Outlook and Marriage Views
Despite the heavy institutional weight resting on his shoulders, the prince’s immediate focus remains his studies. During his debut press appearance following his coming-of-age ceremony last year, Hisahito expressed a desire to travel overseas eventually to gain new perspectives and meet people from different backgrounds and cultures according to AP coverage.
“About marriage, I haven’t thought about an ideal timing or a partner yet.”

As the imperial institution navigates an aging demographic reality alongside deepening public debates over gender equity in governance, the path forward for Japan’s throne remains inextricably tied to how these modern social tensions are resolved.
