Princess Aiko, the 24-year-old daughter of Emperor Naruhito, is making her mark as a full-time employee with the Japanese Red Cross Society after earning a degree in Japanese literature. Meanwhile, Japan's first female prime minister, Sanae Takaichi, emphasized the importance of the male line in the imperial lineage, which has persisted for 126 generations, as a cornerstone of the emperor's authority.

Seiichiro Noboru, a former Japanese diplomat with connections to the imperial family, has criticized recent revisions that aim to prevent a female emperor. These changes allow princesses to stay in the imperial family after marrying commoners but prohibit them from inheriting the throne, while adopted male descendants from former branches can’t inherit either, although their future male offspring would be eligible. The revisions are designed to secure the number of imperial family members and ensure they can continue their public duties as the family faces a decline in numbers and aging members.
