Episode 57:
My Sister, My Master: The Enslaved Life of a High School Dropout

A call comes in from a residential street in Osaka: a young woman has collapsed outside a gate. When paramedics arrive, she's barely conscious — but manages a faint smile. "I fell down the stairs. I'm okay."

She wasn't. She was rushed to the hospital, and by the following midnight, she was dead. The victim was seventeen-year-old Yuriko Tashiro.

Under her long sleeves and long pants, doctors found countless scars, multiple fractures, and internal bleeding. She weighed just 88 pounds. This was no accidental fall.

A Story That Didn't Add Up

The autopsy found the cause of death was a cardiac contusion — a hard blow to the chest. Investigators, sensing Yuriko had been covering for someone, started asking around the neighborhood instead of going straight to her family.

Neighbors described a girl who'd stopped attending school, lost significant weight, and always walked hunched over, staring at the ground — sometimes trailed by a young man aggressively telling her to hurry. Medical records added dental injuries, facial paralysis, and severe malnutrition, each visit explained away with a different accident: a bike crash, a motorcycle collision. Three months earlier, she'd been treated for injuries needing nine weeks to heal, then discharged herself after just two days.

Money Going to the Wrong Name

Yuriko had dropped out of high school and was working packaging shifts at a factory for about $1,100 a month. When police visited, the owner was startled — her paychecks had been deposited not into her own account, but into one belonging to her older sister, Eriko Tashiro.

The sisters had once been close. But Eriko, once a promising swimsuit model scouted in high school, abruptly quit everything after meeting an unemployed man nine years her senior, Daigoro Umezaki, on a dating site. She dropped out, cut off her family's objections with violence against their mother, and eventually moved Umezaki into the family home after their mother left in 2008, unable to take any more.

Two Years as a Slave

With Eriko jobless since quitting modeling and Umezaki never employed, the couple needed money — and decided Yuriko would provide it. They pulled her out of school, confiscated her phone, cut her off from friends, and forced her into factory work while pocketing every paycheck.

To keep her compliant, they starved her until she was skin and bone, then beat her for the smallest offense — using a metal knuckle duster Eriko kept for the purpose, a wooden chair, whatever was within reach. They once shaved part of her head for being "disobedient" and drained their father's bank account through her without his knowledge, spending the stolen money on games and drinking. A youth counselor did visit after a neighbor's report, but Yuriko — controlled and afraid — insisted she was fine, and the visits stopped.

Final Thoughts

On September 11, 2010, Yuriko said she felt unwell. Eriko exploded, accusing her of faking it to avoid work, and the abuse turned frenzied — Umezaki handing over the knuckle duster mid-beating. When the couple's guard dropped, Yuriko dragged herself outside and collapsed at the gate, telling paramedics to the end that she'd simply fallen down the stairs.

Eriko and Umezaki were arrested two months later and denied everything until the evidence — medical records, bank statements, neighbor and teacher testimony — made denial pointless. At trial, each blamed the other as the instigator. The court convicted them of manslaughter: thirteen years for Eriko, fourteen for Umezaki.

Their father and older brother lived in the same house throughout and later claimed they had no idea what was happening — even though neighbors had already reported it to a youth center. Yuriko wasn't killed by her sister and her boyfriend alone. She was let down by everyone who shared her home and did nothing.
