The Center Reform Union party has conditionally accepted a proposal to welcome male descendants of former imperial branches back into the royal family through adoption [1].

This shift is significant because it addresses the long-standing crisis of a shrinking royal family and the strict requirement for male-line succession in Japan. By allowing the adoption of men from former imperial branches, the party aims to stabilize the throne's succession and increase the number of working royals [3].

The decision followed the fifth meeting [1] of the "Headquarters for the Study of Stable Imperial Succession," which took place within the National Diet on May 11 [1]. During the session, the party expressed a willingness to consider the formal institutionalization of this adoption process [1].

According to reports, the party approved a summary plan that basically accepts two primary proposals from the government's expert panel [4]. This move is seen as a way to increase the feasibility of amending the Imperial House Law [3].

Director Kasamoto of the Center Reform Union described the agreement as a tangible achievement, though he acknowledged the outcome might not be a perfect solution for everyone.

"The fact that we were able to summarize the party's view is a certain achievement," Kasamoto said. "This may not be a perfect score for everyone. However, while opinions were asserted, in the end, I was entrusted to summarize them."

While some members within the party continue to call for further deliberation, the general stance is now one of conditional acceptance [5]. The proposal focuses on maintaining the agnatic, or male-line, succession tradition while expanding the pool of eligible candidates to ensure the monarchy's survival [3].

The party indicated it would conditionally accept bringing male descendants of former imperial branches back into the royal family.

This development signals a strategic compromise by the Center Reform Union to preserve the traditional male-only succession system. By supporting the adoption of former imperial males, the party provides a legislative path to bolster royal numbers without conceding to the more controversial proposal of allowing female succession or female emperors, thereby bridging the gap between traditionalists and the need for a sustainable royal lineage.
