Princess Aiko, the only child of Emperor Naruhito and Empress Masako, celebrated her 23rd birthday on Sunday as questions about her future in Japan’s male-dominated imperial system persist. A recent university graduate, Aiko has taken on official duties, including work at the Red Cross Society and participating in palace rituals. However, Japanese law mandates that she must relinquish her royal status if she marries outside the imperial family.
While public opinion overwhelmingly supports changes to allow female emperors, conservative lawmakers maintain strict adherence to male-only succession. With just four male members left in the dwindling 16-member royal family, including 18-year-old Prince Hisahito as the last heir apparent, the system faces sustainability challenges. Proposals to adopt male heirs from former noble families are under consideration but have sparked debate.
