In a recent meeting of the Japanese Senate Budget Committee, Prime Minister Sanae Takaichi engaged in a heated debate with Renho, a member of the Constitutional Democratic Party, regarding the proposed introduction of a system that would allow couples to choose different surnames after marriage. Takaichi took a firm stance, expressing her apprehension towards the implementation of such a system, while advocating for an expansion of the use of maiden names in a non-official capacity. She emphasized the importance of maintaining the same family name within registries, arguing that it enhances family cohesion.

Renho challenged Takaichi's position by questioning whether the arrangement of having different surnames underlines familial unity, stating that if the use of a maiden name becomes commonplace, the shared family name would only exist in official documents. Takaichi responded by clarifying that she does not prioritize family cohesion in the way Renho suggests. Reflecting on her own marriage, she noted that she identifies as Takaichi professionally, while being registered as Yamamoto, stating that she feels no discomfort or confusion from this duality.

The discussion highlighted broader societal issues regarding the flexibility of name usage in Japan. Takaichi mentioned that while there might be some challenges in practice—particularly with businesses not adapting to name changes—efforts are underway by the government to alleviate these inconveniences. Meanwhile, Renho, whose parents were in an international marriage, underscored the necessity for a more inclusive system that recognizes diverse family structures across modern Japan.
