Japan’s parliament has approved revisions to its imperial law, addressing concerns about the dwindling number of potential heirs. The amended legislation allows for the re-adoption of male descendants from former imperial family branches into the main line of succession, provided they remain unmarried. Notably, the changes do *not* alter the longstanding rule prohibiting female emperors; the throne will remain exclusively male. However, female imperial family members will now be permitted to keep their royal status even after marrying outside the imperial family—a right previously held only by male royals. This adjustment seeks to maintain the stability of the imperial household amid declining birth rates and a shrinking pool of eligible successors. While seen as a partial modernization, critics argue the law fails to address fundamental issues of gender inequality within the imperial system. The revisions aim to ensure the continuation of the imperial lineage without altering the core patriarchal structure.
