From Nanking's Horror to Organized Slavery: How Mass Rape Led to the "Comfort Women" System

In December 1937, Minnie Vautrin stood at the gates of Ginling College in Nanking, physically blocking Japanese soldiers from dragging Chinese women out of the refugee camp. She would repeat this act dozens of times each day for weeks. Her diary entries from that period make for harrowing reading: soldiers arriving in trucks to select women like livestock, girls as young as 11 being targeted, women stabbed with bayonets when they resisted.
Vautrin and other Safety Zone members documented approximately 20,000 cases of rape in Nanking in just the first month of occupation. The actual number was almost certainly much higher—most victims never reported what happened to them.
The mass rape of Nanking shocked the world. Film footage smuggled out by George Fitch, reports filed by the International Committee, and testimonies from neutral witnesses made it impossible to deny. Even some Japanese military leaders were embarrassed by the scale and brutality of the sexual violence their troops had committed.
But the Japanese military's response to this international scandal wasn't to prosecute perpetrators or reform soldier conduct. Instead, they decided the problem was that the rapes were unorganized. Their solution was to systematize sexual violence—to establish an official system of military brothels staffed by women coerced, deceived, or outright kidnapped into sexual slavery.
This was the birth of the "comfort women" system, one of the twentieth century's most horrific examples of state-sanctioned sexual slavery. And it grew directly from what happened in Nanking.
The "Problem" the Military Saw
To understand the twisted logic that led from Nanking to the comfort women system, you have to understand how Japanese military leadership viewed the mass rapes.
They didn't see them as a moral catastrophe or a crime against humanity. They saw them as a public relations problemand an operational inefficiency.
The rapes at Nanking had created several issues from the military's perspective:
International outrage: The testimony of Safety Zone members and the film footage from Nanking had made international headlines. American missionaries were showing footage of atrocities in churches across the United States. This damaged Japan's image as a "civilizing force" in Asia and complicated diplomatic relations.
Venereal disease: Uncontrolled sexual violence led to the rapid spread of VD among troops, reducing combat effectiveness. Military doctors were reporting alarming infection rates.
Security risks: Soldiers forming relationships with local women created potential for espionage. Local women might report troop movements or other intelligence to resistance forces.
Lack of discipline: The uncontrolled looting, rape, and murder demonstrated a breakdown in military order. Officers had lost control of their men.
Notice what's missing from this list: any concern for the victims. Any recognition that rape is a war crime. Any acknowledgment that soldiers shouldn't be raping anyone under any circumstances.
The military's goal wasn't to stop sexual violence—it was to manage it more efficiently.
The "Solution": Organized Sexual Slavery
In the months following Nanking, the Japanese military formalized a system that had existed on a smaller scale since the early 1930s. They would establish military-controlled brothels—"comfort stations"—staffed with women who would provide sexual services to Japanese soldiers.
The military's reasoning was coldly pragmatic:
Controlled environment would reduce public rapes that created bad publicity
Medical inspections would control venereal disease rates
Military oversight would prevent security leaks
Regulated access would maintain military discipline and unit cohesion
On paper, the system presented itself as voluntary—women would be recruited and paid. In reality, it was slavery dressed up in bureaucratic language.
How the System Actually Worked
Between 1932 and 1945, an estimated 200,000 to 400,000 women were forced into sexual slavery as "comfort women" (the euphemistic Japanese term "ianfu" translates more accurately as "comfort women," though "military sexual slaves" would be more honest).
The women came from across Japan's empire and occupied territories:
Korea provided the largest number—young women and girls (some as young as 11 or 12) were recruited through deception, coercion, or outright kidnapping. Recruiters promised factory jobs, nursing positions, or other work, then delivered girls to comfort stations.
China supplied many victims, often women and girls taken during military operations. Some were survivors of massacres like Nanking who were then forced into sexual slavery.
The Philippines, Indonesia, Taiwan, and other occupied territories all supplied victims through various combinations of deception, economic coercion, and force.
Japan itself provided some women, typically from impoverished backgrounds, recruited through misleading promises about the nature of the work.
Once in the system, women were trapped. They were:
Confined to comfort stations under guard
Forced to service 10-30 men per day (more on weekends and before battles)
Given no choice in accepting customers
Provided minimal medical care
Paid little or nothing (most earnings went to operators)
Prevented from leaving even if sick or injured
Moved from station to station as military units moved
This wasn't prostitution. It was rape on an industrial scale, systematized and supervised by the military.
The Safety Zone Members' Testimony
The connection between Nanking and the comfort women system is evident in the testimony of the Safety Zone members who witnessed both the mass rapes in Nanking and, in some cases, the establishment of comfort stations.
Minnie Vautrin's diary documents her desperate efforts to protect women from being taken from the college grounds. She describes soldiers arriving with lists, demanding specific numbers of women, sometimes claiming they would just be used for "laundry work" or "kitchen duty." She knew what actually awaited them.
John Rabe's diary includes reports of Japanese authorities establishing military brothels in Nanking soon after the massacre. He noted with dark irony that the military seemed to think that organizing rape would somehow be better than unorganized rape.
George Fitch wrote letters describing the establishment of regulated brothels as part of the occupation authorities' attempt to restore "order"—not by punishing rapists, but by institutionalizing sexual access to women.
The Safety Zone members understood what they were witnessing: the military's response to the PR disaster of Nanking wasn't to prevent sexual violence, but to make it more systematic and less visible.
The Fundamental Failure of the System
Even by its own twisted logic, the comfort women system failed to achieve its stated goals.
It didn't prevent rape. Soldiers continued to rape civilians throughout occupied territories. The comfort stations were supplemental to, not a replacement for, sexual violence against local populations. In Manila in 1945, Japanese soldiers massacred 100,000 Filipinos and raped thousands of women—even though comfort stations were operating in the city.
It didn't control disease. Medical inspections were inconsistent, treatment was minimal, and soldiers often ignored regulations about condom use. VD rates remained high throughout the war.
It didn't prevent security breaches. The complex logistics of running comfort stations—recruiting women, transporting them, supplying stations—actually created more security vulnerabilities than relationships with local women ever did.
It didn't improve discipline. If anything, the system reinforced the idea that soldiers were entitled to sexual access to women. It normalized sexual violence rather than controlling it.
What the system did accomplish was to facilitate the rape of hundreds of thousands of women in a more organized, sustained, and thorough way than spontaneous sexual violence could have achieved. It industrialized rape.
The Denial Continues
Just as Japan has spent decades denying or minimizing the Nanking Massacre, it has denied the coercive nature of the comfort women system.
The official line from Japanese nationalists has evolved over time:
"It never happened" (contradicted by too much evidence)
"They were willing prostitutes" (contradicted by survivor testimony and military documents)
"They were well paid" (contradicted by records and survivor accounts)
"It was a private operation" (contradicted by military documents showing government involvement)
"Other countries did it too" (deflection that doesn't address Japanese culpability)
"The survivors are lying for money" (particularly cruel given how little compensation victims have received)
In 2015, Japan and South Korea reached an agreement meant to settle the issue. Japan expressed "apologies and remorse" and provided 1 billion yen (about $9 million) to support surviving victims. But many survivors rejected the deal, saying it didn't provide adequate acknowledgment of the military's role or proper compensation. The fund worked out to about $90,000 per survivor—a pittance for a lifetime of trauma.
More troublingly, some Japanese officials have continued to deny or minimize the coercive nature of the system even after the agreement. The same pattern we see with Nanking denial continues with comfort women denial: minimize the scale, question the survivors' credibility, deflect to other nations' behavior, and avoid clear acknowledgment of state responsibility.
The Through Line from Nanking
The connection between the Nanking rapes and the comfort women system reveals something important about how atrocities escalate:
First: Soldiers commit mass sexual violence during an invasion (Nanking, December 1937).
Second: Rather than punish the perpetrators, military leadership treats the problem as one of public relations and operational efficiency.
Third: The "solution" is to systematize the violence—making it more organized, more hidden, more sustained.
Fourth: The systematic violence becomes normalized, expanding across the empire and lasting for years.
Fifth: After the war, the same denial mechanisms apply to both: question the scale, blame the victims, deflect responsibility, resist acknowledgment.
Minnie Vautrin understood this trajectory. In 1940, unable to escape the psychological trauma of what she had witnessed in Nanking, she took her own life. Her diary remains as testimony to both what she saw and what it cost her to bear witness.
The women she tried to protect at Ginling College, the Chinese women raped in Nanking, and the Korean, Chinese, Filipino, Indonesian, and other women forced into sexual slavery as comfort women are all connected by the same fundamental disregard for women's humanity.
Why This History Matters
The comfort women system wasn't an aberration or the work of rogue officers. It was official military policy, documented in military orders, logistics records, and administrative documents. It was systematic, organized, and sustained for over a decade.
The survivors—the few who are still alive—are now in their 80s and 90s. They have spent their post-war lives fighting for acknowledgment. Many suffered in silence for decades, stigmatized by societies that blamed victims of sexual violence. Those who did speak out were often dismissed, attacked, or ignored.
Organizations like the Korean Council for Justice and Remembrance for the Issues of Military Sexual Slavery by Japan continue to demand:
Full acknowledgment of the coercive nature of the system
Proper apologies that don't equivocate
Compensation that reflects the severity and scale of the crime
Education in Japanese schools about what actually happened
Memorials to the victims
These are reasonable demands. They're the minimum owed to women who were enslaved, raped repeatedly for years, and then denied justice for decades.
The through line from Nanking to the comfort women system shows how one atrocity led to another—not through remorse and reform, but through bureaucratic reorganization of violence. The Safety Zone members who documented the Nanking rapes were witnessing the event that would lead to an even more sustained and systematic sexual violence.
George Fitch smuggled out film footage of Nanking because he believed the world needed to know. Minnie Vautrin kept her diary because she believed someone needed to bear witness. John Rabe filed his protests because he believed documentation mattered.
They were right. The evidence they created makes denial harder. Their testimony connects Nanking's horror to the broader pattern of Japanese military conduct—including the comfort women system that grew directly from it.
Understanding Through Story
Historical documentation is essential, but narrative brings history to life in ways that statistics and official records cannot. Nanking Safety Zone takes readers inside the lived experience of those desperate December weeks—not just as observers, but as participants in the moral choices faced by the Safety Zone members. Through the eyes of characters like Minnie Vautrin fighting off soldiers at the gates, or witnessing the terror of young Chinese women like Mei Lan hiding from Japanese Soldiers, readers begin to understand the visceral horror that the comfort women system was designed to perpetuate. The novel doesn't sanitize or distance—it immerses you in the fear, the courage, the impossible choices, and the psychological cost of bearing witness. When you read about Minnie Vautrin's desperate attempts to protect girls barely into their teens, you begin to grasp not just what happened, but what it felt like—the panic, the helplessness, the moral anguish. This emotional understanding is what transforms historical knowledge into genuine comprehension of why these events must never be forgotten or denied.
The comfort women deserve the same unflinching acknowledgment that the Nanking victims deserve. The same political courage required to face what happened in Nanking is required to face what happened in the comfort stations. Japan cannot claim to have learned from history while denying so much of it.
The witnesses spoke. The survivors testified. The evidence exists. What remains is the question of whether Japan—and the world—will truly listen.
The stories of the Nanking Safety Zone members and the comfort women survivors are connected by themes of bearing witness, seeking justice, and fighting for historical truth. Both demonstrate the cost of sexual violence in war and the importance of documentation in preventing denial.
