The Japanese government is planning a reform of the Imperial Household Law that is to pave the way for the adoption of male descendants of former collateral lines – women like Princess Aiko will thus continue to be denied the throne.
The Japanese government wants to amend the Imperial Household Law before the end of the current parliamentary session on Friday (7/17). The aim is to incorporate male members of former collateral lines, who lost their status after the Second World War and lived as private citizens, into the imperial family. This is intended to alleviate the long-lamented shortage of male heirs to the throne.
The planned reform in detail
A prerequisite for such an adoption is, according to the plans, that the candidates be at least 15 years old and unmarried. "Whoever among them is at least 15 years old and unmarried could be adopted," according to the outlines of the plan. The adopted individuals themselves would not be eligible for the succession, but their male descendants would be.
