Japan’s parliament passes changes to the Imperial House Law aimed at addressing a shrinking imperial family, but it keeps the existing ban on women ascending to the Chrysanthemum Throne. Under the revised rules, male relatives from former imperial branch families can be adopted back into the imperial household, provided they meet eligibility conditions described in the legislation, including an age threshold. The law also allows members of the imperial family to keep their imperial status even after marrying commoners, a change aimed at reducing barriers for those marriages.
Across coverage, the core outcome remains the same: the throne continues to pass through the male line. As a result, Princess Aiko—Emperor Naruhito’s daughter—does not become eligible to succeed him under the new framework. Several outlets note that the current line of succession includes only men and that the reform does not alter the sex-based restriction that prevents a woman emperor.
The measures come despite public opinion in Japan showing broad support for allowing women to rule, with the revised legislation instead focusing on expanding the pool of eligible male relatives and preserving imperial status after marriage.
