Japan’s parliament enacts revisions to the Imperial House Law that aim to address concerns about the shrinking number of eligible heirs, while preserving the existing prohibition on women becoming emperors. Under the changes passed on Friday, male members from former imperial branch families are allowed to be adopted back into the imperial family, including those aged 15 and over. The revised law also provides that female members of the imperial family can retain their imperial or royal status after marrying commoners, a rule that is designed to prevent loss of status for princesses and women in the family.
The legislation keeps the male-only succession system, meaning only men with a paternal lineage can ascend the Chrysanthemum Throne. Several outlets note that opinion polls indicate broad public support for allowing a female emperor, but conservative opposition remains. The reforms are intended to strengthen the future pool of male heirs as the imperial family ages and the number of male descendants is limited, with succession currently tied to the emperor’s younger male relatives.
