A mother who spent 29 years caring for her severely disabled daughter—alone—took her child's life. "I didn't intend for only my daughter to die. I meant to die too." This is a murder case. But should this mother alone bear the weight of this crime? In Japan, tragedies like this keep repeating. How long can society look the other way?

What Happened in Mobara, Chiba

In the early hours of March 8, 2026, a 58-year-old mother was arrested in Mobara City, Chiba Prefecture, on suspicion of murdering her 29-year-old daughter.

The daughter had been born with a severe congenital physical disability and had been bedridden her entire life. For 29 years, the mother cared for her at home while also arranging for her to attend a welfare facility during the day. They lived alone together—just the two of them.

The mother drowned her daughter by submerging her face in a storage container filled with lukewarm water. She then attempted to take her own life but survived. She told a nearby resident, "I killed my daughter," which led to the police being called.

During questioning, the mother stated that she had "lost hope for her daughter's future and attempted a forced double suicide"—a phenomenon known in Japanese as muri-shinjū, where a caregiver kills the person in their care before attempting suicide, often driven by despair rather than malice.

Twenty-nine years. More than 10,000 days. What must those days have looked like for this mother?

A Repeating Tragedy: Japan's Dark Reality of "Caregiver Murder"

This case is far from isolated.

In Japan, approximately 40 cases of murder or attempted murder-suicide linked to caregiving difficulties are reported each year. Between 1998 and 2015, a total of 716 fatal cases were documented—and the numbers have not decreased even after the introduction of Japan's Long-Term Care Insurance system in 2000.

Just one year ago, in March 2025, another verdict drew public attention. In Yasu City, Shiga Prefecture, an 82-year-old father who had spent 34 years caring for his son—left bedridden after a traffic accident—killed him with his consent. The Otsu District Court handed down a sentence of three years in prison, suspended for four years. The judge acknowledged that "taking a life cannot be permitted" but considered the father's decades of devoted care, his own advanced age, and his declining health.

In 2006, a case in Fushimi Ward, Kyoto, became a watershed moment. A 54-year-old son who had been caring for his mother with dementia applied for welfare assistance three times but was rejected each time. Financially and emotionally cornered, he killed his mother and attempted to take his own life. At trial, even the prosecution detailed the defendant's desperate circumstances—an extraordinary move. Not only the gallery but also the judge was moved to tears. The sentence was two years and six months, suspended for three years. The presiding judge added a remarkable statement:

"It is not only the defendant who is being judged here. The very systems of long-term care insurance and public welfare are on trial."

Yet this man, who had vowed to rebuild his life after receiving a compassionate verdict, took his own life eight years later. Among his belongings were a few hundred yen in coins, two umbilical cords—his own and his mother's—and a note that read: "Please cremate these together."

"Just Ask for Help" Is Advice Only the Privileged Can Give

Every time a case like this makes the news, the same chorus of responses follows:

"They should have consulted the government." "They should have used welfare services." "They should have asked someone for help."

These words may be logical. But they come from a place of privilege—from those who still have the capacity to ask.

Japan has a deeply ingrained cultural value: meiwaku wo kakete wa ikenai—"you must not be a burden to others." Even when struggling, many people cannot bring themselves to speak up. Asking for help itself is felt as shameful. The man in the Kyoto case had been raised by his father with the teaching: "You must never live in a way that burdens others." He followed that principle faithfully—so faithfully that even after being turned away from welfare offices three times, he could not push back.

The isolation of caregivers is not a sign of personal weakness. It is a problem created by the very structure of Japanese society.

Statistics on caregiver killings reveal that approximately 37% of cases occurred in households where only the caregiver and care recipient lived together. In about 29% of cases, the caregiving burden was concentrated on a single person. And in roughly 31% of cases, the caregivers themselves had disabilities or mental health conditions. In other words, the very people providing support were the ones who needed it most.

What Is Government—What Is Society—For?

Japan's Long-Term Care Insurance system launched in 2000 with a stated ideal: kaigo no shakai-ka—the "socialization of caregiving." The idea was that care should no longer be a burden borne by families alone but shared across all of society.

But what is the reality?

The fact that roughly 60% of primary caregivers are family members living with the person they care for has barely changed in the quarter-century since the system began. Special nursing homes have long waiting lists, and only a fraction of those who need them can get in. Home care services remain thin during nighttime and early morning hours—a gap that has been pointed out for years. And when it comes to caring for a child with disabilities, the situation falls outside the framework of long-term care insurance entirely, leaving even wider gaps.

In the Mobara case, the mother had been sending her daughter to a care facility. She was not completely disconnected from the system. Yet 29 years of relentless pressure still drove her to the breaking point. The system existed—but it failed to save her.

What are governments and societies fundamentally for? Are they not meant to share the burdens that no individual can carry alone? In Japan, the phrase ji-jo, kyo-jo, kō-jo—"self-help, mutual help, public help"—is often invoked. But it is typically interpreted in that exact order: "First, figure it out yourself." The true role of public assistance, however, is to catch those who have already reached the limits of self-help. If it fails to do that, then society itself has failed.

Who Should Bear This Guilt?

Legally, this is a murder case. The mother committed a crime. The fact that a life was taken cannot be undone.

But is it truly justice to place the full weight of guilt on a woman who spent 29 years caring for her daughter alone, lost hope for the future, and tried to die alongside her child?

In similar past cases, courts have repeatedly stated, in one form or another, that "it is not only the defendant who is on trial—society itself is being questioned." These words represent the judiciary acknowledging its own limitations. The law can judge people. But it cannot save those who have been driven to despair. What saves people is not the law—it is the fabric of society itself.

Each time a caregiver killing occurs, society grieves, pays attention for a moment—and then forgets, until the next tragedy strikes. Breaking this cycle requires not individual effort but systemic reform and a fundamental shift in societal awareness.

Part of the guilt this mother carries undeniably belongs to society as well.

What About in Your Country?

In Japan, tragedies surrounding caregiving show no signs of stopping. Behind them lie a culture that says "don't be a burden to others," a social structure that places caregiving squarely on families, and the existence of people who fall through the cracks of support systems.

How does your country support families who need long-term care? When caregivers are pushed to the brink, what safety nets does your society offer? How does your society reach out to those who cannot bring themselves to say "help me"?

We'd love to hear about the experiences and perspectives from your country.
