During the House of Representatives budget committee meeting, Prime Minister Sanae Takaichi acknowledged that there is a need for 'dual listing' of maiden names on official documents like passports, driver's licenses, and My Number cards. This statement comes after her directive to consider the legal implementation of using maiden names for individuals who change their surnames after marriage. There has been significant pushback from conservative factions regarding the implications of standalone-use of maiden names, which could lead to a perception of family separation.

Takaichi's recommendations to extend the use of maiden names were made amidst concerns about the impact of such changes on social structures, particularly the traditional notion of married couples sharing a surname. In a recent meeting, politician Rina Yoshikawa expressed worry that allowing the single use of maiden names could effectively create situations close to separate surnames within families. Prime Minister Takaichi responded by asserting that introducing single use without adequate safeguards could present new risks, particularly for strict identification processes in official documents.

The discussion surrounding the legal recognition of maiden names is tightly interwoven with the politics of marital naming conventions in Japan. Should the legislation be passed under the current premise, some observers fear it may quell momentum for the introduction of optional separate surnames for married couples. Therefore, establishing protocols for maiden name usage may indicate a gradual shift toward broader acceptance but remains controversial among conservative lawmakers and segments of the populace.
