Matchmaking events pair singles with identical surnames to bypass Japan's 128-year-old marriage law

A Japanese advocacy group and a matchmaking firm organized events for singles with the same last name to sidestep the legal requirement that married couples share a surname. The law, Article 750, has been cited by many women as a deterrent to marriage, contributing to declining birth rates. The initiative aims to spotlight the issue and push for legislative change.
The matchmaking events, held in Tokyo and online, specifically targeted individuals with the surname Suzuki, Japan’s second most common name. Asuniwa’s partnership with IBJ reflects a creative, low-cost workaround to a legal hurdle that disproportionately affects women, who often bear the burden of changing official documents. The 2021 government survey highlighted that nearly a third of women cited surname change as a marriage deterrent, versus under a tenth of men. Meanwhile, a 2024 study projected that if the law persists, every Japanese citizen could share the surname Sato by 2531, underscoring the demographic and cultural stakes behind the advocacy.
This initiative could subtly shift public discourse on Japan’s marriage and birthrate crisis, normalizing the idea that legal reform is necessary. By making the surname issue tangible and even playful, it may pressure lawmakers to revisit Article 750, while also offering a practical, if limited, solution for some couples. However, its impact is likely symbolic rather than systemic, as only those with common surnames benefit. Broader societal effects may emerge if the events amplify women’s voices and encourage more open debate on gender equality in family law.
