South Korea edges toward mandatory military service for women amid demographic crisis

South Korea is edging toward a decision that would fundamentally reshape its military conscription system: requiring women to serve alongside men. A survey released in August found that nearly 60 percent of South Koreans now support mandatory military service for women, a striking reversal of a long-standing cultural taboo. The shift reflects three converging pressures—a collapsing birth rate that is shrinking the pool of eligible male conscripts, an intensifying national conversation about gender equality, and a military establishment grappling with how to defend the peninsula in an age of drones and cyber warfare rather than mass infantry.

Thousands of women already volunteer in South Korea's armed forces, but the question of whether to compel them to serve has always been politically delicate. That restraint is breaking. According to the Reform Institute, the policy research arm of the conservative Reform Party, support for mandatory female conscription runs at 65 percent among men overall and climbs to 71.7 percent among men in their twenties and thirties. Even among women, 54.5 percent across all age groups favor the change. The numbers suggest a generational shift in how South Koreans think about the relationship between citizenship, obligation, and gender.

The demographic math is unforgiving. In 2019, approximately 332,000 men were eligible for mandatory military service. By 2022, that figure had fallen to 257,000. Projections show it will plummet to just 120,000 by 2043. Every able-bodied man currently serves between 18 and 21 months, with the possibility of recall in a national emergency. The Korean Peninsula remains technically at war; the armistice with North Korea has held since 1953, but no peace treaty was ever signed. The military cannot sustain itself on a shrinking male population alone.

Hyobin Lee, a professor at Sogang University in Seoul, traces the cultural roots of the old system. For generations, South Korean society assigned men the duty to protect the nation and family through military service, while women bore responsibility for childbirth, childcare, and household management. That division is no longer holding. As women's participation in education and employment has expanded, younger men have begun asking a straightforward question: if equality is the goal in rights and opportunities, why does one of the country's most significant civic obligations fall only on them? The question has gained force precisely because it comes from men, not as a demand from women's advocates but as a complaint about fairness.

The nature of modern warfare has shifted the terms of the debate. The military increasingly relies on unmanned systems, cyber capabilities, and information technology—domains where physical strength is irrelevant. The old argument that combat roles require male bodies no longer holds water. Yet Lee, despite her support for gender equality across South Korean society, harbors serious reservations about mandatory service for women. She points to a stubborn reality: women in South Korea still bear a disproportionate share of pregnancy, childbirth, and childcare responsibilities. Career interruption after having a child remains common. If women were also required to surrender 18 months in their twenties to military service, the cumulative burden across their lifetimes could become crushing. In a country already experiencing one of the world's lowest birth rates, the additional obligation might further discourage marriage and childbirth.

Lee comes from a military family—her grandfather was a naval admiral, her father served in the navy—but she acknowledges she would have found mandatory service difficult. Eighteen months in your twenties is not a small thing; it is the time when people study, launch careers, and make personal choices. The state demanding that sacrifice is a substantial burden, she said.

Opposition to mandatory female conscription exists, though it remains a minority view. Song Young-Chae, a Seoul-based academic and human rights activist who himself completed two years of infantry service along the Demilitarized Zone, argues that national defense has traditionally been men's responsibility and that South Korea should instead invest heavily in drones, robots, and advanced military technologies. The government established a task force in 2025 to overhaul the conscription system, which has been in place since the 1950s. Military Manpower Commissioner Hong So-young acknowledged in August that the nation faces a "demographic cliff" and that reforms are urgent. He mentioned potentially reducing exemptions and requiring foreign-born naturalized citizens to serve, but made no public statement about mandatory service for women. The defense plan revision is scheduled for release in autumn, and the question of whether women will be conscripted remains unresolved—though the momentum, and the numbers, suggest the taboo is breaking.
