Japan’s upper house of parliament has approved a revised Imperial House Law aimed at ensuring the stability of the royal family’s succession. The key changes allow female imperial family members to remain members of the family even after marriage, previously causing them to lose their status. Additionally, the revision enables the adoption of male descendants from former imperial family branches as potential heirs. This addresses concerns regarding the dwindling number of eligible heirs to the Chrysanthemum Throne. The bill passed with a majority vote in the House of Councillors, following previous approval in the lower house. Supporters of the reform argue it is crucial to maintain a stable imperial line, while debate continues regarding broader succession reforms. The revised law seeks to address the immediate challenges faced by the imperial household concerning royal lineage.
