Japan's legislative leaders gave general approval Friday to a draft amendment of the Imperial House Law aimed at securing the imperial succession [1].

The move is critical as the Japanese government seeks to prevent the imperial family from shrinking, a challenge that threatens the long-term stability of the monarchy. The proposed changes would allow female members of the imperial family to remain in their positions after marriage, and enable the adoption of male descendants from former imperial branches [1].

Chief Cabinet Secretary Kihara detailed the outline of the amendment during a meeting held Friday afternoon at the official residence of the Speaker of the House of Representatives in Tokyo [1]. The session lasted approximately 90 minutes [1]. Kihara briefed four officials, including Speaker of the House of Representatives Hanae Mori, and the speakers and vice-speakers of both the House of Representatives and the House of Councillors [1].

Following the briefing, the legislative leaders expressed their broad agreement with the proposal. Mori said the four leaders determined the content aligned with the consensus of the legislative branch and therefore gave their general approval [1].

Despite the general agreement, some details remain unresolved. Mori said that final adjustments are still required [1].

The government plans to continue the process with another briefing scheduled for the afternoon of June 22 [1]. These discussions are intended to finalize the language and structure of the amendment before it moves to the next stage of government approval. The government expects to reach a formal cabinet decision by June 26 [1].

The proposed reforms represent a significant shift in traditional succession rules, which have historically limited the imperial line to male descendants. By introducing mechanisms to retain female members and integrate former imperial branches, the government aims to create a more sustainable framework for the throne's future [1].

The proposed changes would allow female members of the imperial family to remain in their positions after marriage.

This agreement signals a rare legislative consensus on one of Japan's most sensitive constitutional issues. By combining the ability for women to remain in the imperial family with the adoption of male members from old imperial branches, the government is attempting a hybrid approach to satisfy both modern gender expectations and traditionalist demands for a patrilineal line.
