Summary
The Japanese Diet has reopened discussions on the selective married couple surname system after 28 years, reflecting deep political divisions. The system, which allows couples to retain their original surnames after marriage, aims to address identity and administrative challenges, particularly for women. In 2023, 94.5% of couples adopted the husband’s surname, highlighting the issue’s relevance. Three opposition parties-Constitutional Democratic Party, Democratic Party for the People, and Japan Innovation Party-proposed separate bills, but failed to unify their efforts. The ruling Liberal Democratic Party remains split, with no consensus reached. The debate will continue in the autumn 2025 extraordinary Diet session, amid concerns over political posturing ahead of elections.
