Chapter 1
When Truth Meets Power: The Black Box of Sexual Assault
In the heart of Tokyo, on a spring day in 2017, a woman stood before a crowd of journalists, cameras flashing as she prepared to share her story. This wasn't just any press conference-it was the moment Shiori Ito decided to break Japan's culture of silence surrounding sexual assault. Her book "Black Box" would become a watershed moment in Japan's reckoning with sexual violence, earning her a spot on Time magazine's 100 Most Influential People of 2020. The title references what a prosecutor called her case: a "black box" because it happened behind closed doors-a metaphor for how society treats sexual assault as something unknowable and therefore dismissible. Despite Japan's reputation for safety, Ito discovered that the most dangerous place wasn't in the war zones she'd reported from as a journalist, but in her own country, where the very institutions meant to protect victims failed her completely. Her story would challenge not just one powerful man, but an entire system designed to silence survivors.
Chapter 2
A Journey Interrupted: The Path to That Fateful Night
Long before the assault that would change her life, Shiori Ito was a determined young woman with dreams of becoming a journalist. Born in 1989-the year the Berlin Wall fell and the first year of Japan's Heisei era-she grew up with a strong sense of justice and boundless curiosity. As a child, she once punched a boy who was bullying others, making his nose bleed. This early sense of right and wrong would shape her future path.
Her American mother, raised in rural Japan, allowed her surprising freedom. As a young child, Ito would use their fifth-floor balcony as a jungle gym, even hoisting herself over the railing to visit friends next door-a memory that terrifies her now as an adult. This independence grew stronger after her siblings were born and her parents' attention shifted. She often cared for her younger sister, who followed her everywhere, and they were frequently mistaken for mother and daughter due to their age gap.
At nine years old, Ito began modeling work after an agency manager approached her mother at a public bath. Though initially intended for her sister, Ito's outgoing nature made her better suited for the job. She would follow faxed instructions to auditions, sometimes stopping at her father's office when tired. While the auditions made her uncomfortable, she enjoyed working with adults to create finished products. However, this early taste of standing out would teach her a painful lesson about Japan's social conformity when classmates discovered her modeling work and bullying ensued.
Her life veered dramatically off course when she collapsed after a basketball game in middle school, leading to months of hospitalization. In the hospital school, she encountered students battling various illnesses, gaining perspective on what truly mattered. After returning to regular school, she sought experiences beyond the conventional path, teaching Japanese to foreigners and volunteering at nursing homes while her classmates prepared for entrance exams.
This desire to test herself in unfamiliar environments led her to an exchange program in rural Kansas, funded by her modeling earnings. Instead of the glamorous American high school life she'd imagined, she found herself learning to ride horses and attending rodeos. Despite initial isolation as "an alien who didn't speak the language," she eventually made friends through sports and discovered her passion for journalism by watching international news-her window to the world beyond Kansas.
Chapter 3
Ambition Meets Opportunity: The Path to New York
After her transformative year in Kansas, Ito returned to Japan with a clear vision: to study journalism in New York City. Despite her parents' objections and the prohibitive cost of American universities, she was determined to make it happen. Working multiple jobs around the clock, she saved every penny while also securing a position as a news assistant at a TV station.
The exhaustion eventually caught up with her when she missed a flight for a planned trip after falling asleep while packing. This wake-up call made her realize her approach was financially unsustainable. She pivoted to studying in Germany where tuition was virtually free, planning to earn transferable credits before eventually moving to New York. Her educational journey took her to Spain to study Arabic and international relations, though her planned exchange in Syria fell through due to worsening conditions there.
Throughout this period, she maintained a long-distance relationship, eventually convincing her partner to move with her to New York after she received a scholarship. Her dream of studying journalism in the media capital of the world was finally within reach. In New York, she majored in photography and began making documentaries, continuing her circuitous but determined path toward becoming a journalist.
It was during this time in New York that she first met Noriyuki Yamaguchi, the Washington bureau chief for Tokyo Broadcasting System (TBS). While working at a piano bar, another customer pointed him out as an important figure in Japanese journalism. Their conversation was thrilling as she heard stories from a seasoned professional in her dream field. He gave her his business card and offered to show her around the TBS New York bureau.
Later that autumn, Yamaguchi invited her to join him and the TBS New York bureau chief for lunch. The bureau chief gave her a tour of their office afterward. To Ito, Yamaguchi was simply a successful journalist who knew many people and made helpful introductions-a valuable connection in her chosen field.
As graduation approached in 2014, Ito's relationship ended when her partner wanted her to follow him around the world for his job, suggesting she could "teach yoga" in her spare time. Though she loved yoga enough to study it in India, she couldn't abandon her journalism career. She couldn't compromise her dreams, even for love-all her efforts had been focused on becoming a journalist.
Chapter 4
The Night Everything Changed: April 3, 2015
Financial struggles in New York eventually forced Ito to return to Japan, where she secured a full-time internship with Reuters. While working there, she remembered Yamaguchi's previous offer and contacted him about possibly interning at TBS's Washington bureau. To her surprise, he quickly replied with an opportunity to work as a paid producer rather than an intern-far beyond what she'd hoped for. He asked for her resume and inquired about her visa status, explaining that he could approve her starting as a freelancer.
On April 3, 2015, after covering a sumo tournament for Reuters, Ito met Yamaguchi at Ebisu station in Tokyo. They first went to a small kushiyaki bar he frequented since childhood, where she had a few skewers and drinks while maintaining her composure. During their meal, he asked about her interest in politics, explaining how the Washington bureau focused on political reporting and building connections.
After about ninety minutes, they moved to a sushi restaurant nearby. Strangely, no sushi was served-only small plates with two bottles of sake. Yamaguchi mentioned positive feedback about her from the NTV bureau chief and name-dropped politicians including a former prime minister, seemingly to impress her with his journalistic connections.
Before finishing the second sake bottle, Ito went to the bathroom twice. During her second visit, she suddenly felt dizzy, sat down on the closed toilet lid, and rested her head. That was her last memory before everything went black.
She regained consciousness to excruciating pain in her lower abdomen, finding herself pinned beneath a heavy weight on a hotel bed. Despite her grogginess, she immediately understood what was happening. The room was dimly lit, with curtains drawn and a strangely positioned laptop that appeared to be recording.
Her repeated pleas about being in pain didn't stop him. When he finally asked "It hurts?" he made no move to release her. She struggled desperately but couldn't match his strength. Only when she claimed she needed the bathroom did Yamaguchi finally let her up. In the bathroom mirror, she saw her naked body covered in red marks and bleeding in places.
When she tried to escape, Yamaguchi was waiting outside the bathroom. He grabbed her shoulders, threw her onto the bed, and began raping her again. As she struggled, he pressed her face into the mattress until she couldn't breathe. In that terrifying moment, she thought she was going to die and imagined her mother's grief-stricken face on the morning news.
After several minutes of struggle, he finally stopped. Finding Japanese too timid for expressing her rage, she switched to English: "What the fuck are you doing?" and "Why the fuck are you doing this to me?" She realized later that she'd always used honorific Japanese with him as her potential boss-their language has no register for a woman to protest on equal footing with a male superior.
When Yamaguchi said he wanted to keep her underwear as a souvenir, her body went completely limp. She hastily dressed and fled the room, only realizing in the lobby that she was at the Sheraton Miyako Hotel Tokyo. She took a taxi home around 5:50 a.m., desperately trying to remember anything between being in the restaurant bathroom and waking up, but encountered only blankness.
Chapter 5
The Aftermath: Shock, Confusion, and Silence
Even in the supposed safety of her apartment, Ito couldn't relax or process what had happened. Flashbacks consumed her, and she desperately wished she could escape her own body and the lingering sensations of pain. While curled up in the fetal position, Yamaguchi called around 7 or 8 a.m., speaking in the same businesslike tone as before. He asked if she'd left a black pouch behind and mentioned he'd be in touch about the visa. They both spoke as if nothing had happened.
She was terrified. Yamaguchi was the chief of TBS's Washington bureau with powerful connections in politics and police. TBS was an important client for Reuters, where she worked. If she accused him, would she ever work in the industry again? Would TBS shield him and sue her for defamation?
When her younger sister called about their plans to visit a popular cafe, Ito decided to pretend nothing had happened. Before her sister arrived, she tried to visit an OB-GYN clinic for the morning-after pill. The female doctor was brisk and unapproachable, never looking up from her computer as she wrote the prescription. If she had looked Ito in the eye and asked what was wrong, perhaps everything that followed would have been different.
Though grateful to obtain the morning-after pill without an appointment, she needed more help. She found a nonprofit supporting sexual assault victims online, but they refused to provide information unless she came in person. In her traumatized state, she lacked the energy to travel there, while the critical window for blood tests and DNA collection was closing rapidly.
She took the pill and spent the day with her sister, forcing herself to follow their planned schedule. She was terrified that if she stopped moving, thoughts of what happened would overwhelm her. At this point, she hadn't yet fully acknowledged that what happened was rape-part of her still associated rape with attacks by strangers, and she didn't want to admit she was now a victim.
Her right knee was in such pain she could barely walk. Despite her state, she kept dinner plans with her close friend K. and her family. Later, she met her childhood friend S., a nurse, who noticed her despondent state and gently encouraged her to talk. As Ito haltingly confided about the assault, her friend grasped her hand tightly and wept with her. It was the first time she'd put her experience into words, and the first time she'd shed tears since the attack.
Yamaguchi never responded about the visa. Ito emailed him that night, desperately wanting to forget everything had happened, pretending it was just a nightmare despite her physical pain and mental confusion. He never replied. She realized the producer job was likely never going to materialize-had he just seen her as an "object" rather than a potential colleague?
She couldn't ignore what happened; the trauma only grew larger. What pained her most was that despite her determination to become a journalist committed to presenting facts, she was attempting to stifle the truth within herself. For whose sake was she pursuing journalism if she couldn't face her own truth? She decided she must go to the police-if she didn't live according to her principles, she wouldn't be true to herself in any profession.
Chapter 6
Fighting the System: A Journey Through Japan's Justice System
On April 9, five days after the attack, Ito went alone to the Harajuku Police Department. At the front desk, she had to explain her situation in front of others waiting, repeatedly stating "I was raped" before being directed to a female officer-from the traffic department. After telling her story for two hours, she spent another two hours repeating the same story to a male investigator. He explained that since the incident occurred in Takanawa's jurisdiction, she'd need to return when a Takanawa investigator came to Harajuku.
Two days later, she returned to meet Mr. A., the Takanawa investigator handling her case. His reaction was much sterner than the Harajuku officer's. "It's been a week. That's tough," he said bluntly, adding, "This kind of thing happens all the time, and there's no easy way to investigate cases like these." His casual treatment of sexual assault was chilling. He explained how difficult prosecution would be without immediate DNA evidence.
On April 15, she reluctantly accompanied investigator Mr. A. to the Sheraton Miyako Hotel. Though there was no security camera in the second-floor hallway, they had footage from the hotel entrance showing Yamaguchi dragging her limp body from a taxi and carrying her inside as the bellman watched. Seeing herself unconscious gave her goosebumps and made her nauseous. The footage showed her being carried through the lobby with her feet not touching the ground, disappearing into the elevator, and later fleeing the hotel with her face downcast.
After viewing the footage, she exchanged emails with Yamaguchi. He claimed she had vomited extensively and that he had cleaned up after her, removing her vomit-covered clothes. He denied taking advantage of her while unconscious, insisting she had gotten into bed with him while half-naked. She had no memory of this, and noted the other bed in the room had been completely intact, contradicting his story about sleeping separately.
When she consulted with investigator Mr. A. again, his attitude had completely changed. "We can't arrest him. It's challenging without any evidence," he said dismissively. He argued that even DNA on her bra would only prove contact, not sexual activity, and without semen, conviction would be difficult. He questioned her memory's reliability, demanding exact times and challenging why she had gaps in her recollection.
The day after this discouraging response, Mr. A. called with unexpected urgency. "There might still be a chance," he said, explaining that Yamaguchi had been demoted and was on a fifteen-day suspension in Japan. Mr. A. now wanted her to file the criminal complaint immediately so they could bring Yamaguchi in for voluntary questioning. This sudden shift in attitude surprised her.
On April 30, she filed both a report and criminal complaint at the Takanawa Police Department. She had repeatedly asked Mr. A. to investigate the possibility of date-rape drugs, explaining that she has a high alcohol tolerance and never passes out from drinking the amount she had consumed that night. Mr. A. maintained that too much time had passed for testing.
Chapter 7
The Arrest That Never Happened: Power and Influence
While working in Germany, where she'd found some relief from her panic attacks, Ito received news that Yamaguchi would be arrested upon returning to Japan. Despite what should have been welcome news, she felt numb contemplating the backlash that would follow. The arrest warrant signified that sufficient evidence existed, giving her hope that truth would prevail.
Four days later, on the scheduled arrest day, Mr. A. called with devastating news: "We were not able to arrest him. We were prepared to do so... but at the last minute we were ordered to stop." He apologized for his "inadequacy" and informed her he was being removed from the case. The stop order came from "the top" of the Tokyo Metropolitan Police Department. When she pressed for answers, he could only say "I hope you can pardon my failure." Both the investigator and prosecutor were removed from the case on the same day.
After this shocking halt to Yamaguchi's arrest, Ito found herself dealing with an entirely new investigation team from MPD's First Investigation Division. Their explanations for why the arrest warrant wasn't executed were nonsensical and contradictory. They claimed since no weapon was used, there was no concern about evidence destruction, and his "social status" meant he wouldn't flee. Their reasoning suggested people with higher social standing receive preferential treatment in the justice system.
Strangely, the police seemed eager to push her toward an out-of-court settlement, relaying that Yamaguchi's lawyer wanted to negotiate. "In a situation such as this, it's only ever about money," the officer told her. They offered to connect her with a lawyer specializing in representing victims, whose services would be covered by public funds. Meanwhile, the investigation continued, with DNA analysis confirming Yamaguchi's DNA on multiple parts of her bra.
Several days after meeting with MPD, she was driven to a lawyer's office in a police car with investigators accompanying her. The female lawyer specialized in out-of-court settlements, explaining that many sexual assault cases end with settlements around one million yen. The lawyer seemed to assume she wanted a settlement, though Ito never expressed such interest. She questioned why police were pushing settlement so strongly, especially when what she wanted most was "the truth."
Knowing Yamaguchi had returned to work at TBS-in the same building complex as her Reuters internship-filled her with dread. She became unable to leave the building during lunch, fearing an encounter. Even seeing someone who resembled him triggered panic attacks, and she once fainted at work from the stress.
On August 26, 2015, the case was submitted to the Public Prosecutor's Office. In October, she met with Prosecutor K., now handling her case, and repeated her account yet again. Months later, Yamaguchi quit his job at TBS and published a book about Prime Minister Abe, becoming ubiquitous on television while she avoided seeing his face. On July 22, 2016, the case was officially dismissed, leaving her with a vast sense of helplessness.
Chapter 8
The Black Box: Japan's Legal System and Sexual Assault
Rape remains severely underreported in Japan. According to UN data from 2013, Japan reported only 1.1 rapes per 100,000 population, compared to Sweden's 58.5, the UK's 36.4, and the US's 35.9. These numbers reflect not actual occurrence rates but reporting rates. A 2015 Japanese government survey found one in fifteen women had "been forced to have intercourse by a member of the opposite sex," while US data indicates one in five women have been victims of rape.
Sweden's high rape statistics stem from their counting method-each instance of abuse counts separately, not as a single incident. Their reporting environment is also more supportive, with women comprising 31% of the Swedish police force compared to Japan's 8.1%. This means Japanese victims face mostly male officers throughout the reporting process.
In rape cases, two main points are contested: whether sexual intercourse occurred and whether there was consent. While the first can be proven with medical examination, the second presents a significant challenge. For stranger attacks, consent is rarely questioned, but most rapes involve acquaintances. When suspects claim the encounter was consensual, disproving this becomes extremely difficult.
According to Stockholm's rape center, 70 percent of victims experience "tonic immobility" during assault-an involuntary paralysis similar to animals playing dead when sensing danger. In Japanese rape trials, what's questioned isn't whether the victim refused, but whether refusal was "clearly conveyed" to the perpetrator. This creates what's known as the "consent wall." Essentially, if a suspect claims they "didn't realize" the victim was unwilling, this can legally establish consent.
In Japan, cases where victims are unconscious or don't remember are classified as "quasi-rape"-a distinction that baffles English speakers who insist "rape is rape." Date-rape drugs are frequently used in these cases, yet awareness of them remains low in Japan. Dr. Chieko Nagai, who began researching these substances after treating a patient who was assaulted while unconscious, discovered specialized labs can detect these drugs in urine even days after ingestion, and in blood up to a week later.
For quasi-rape cases in Japan to overcome the "consent wall," specific legal conditions must align. In one successful prosecution, a famous judoka was convicted of assaulting an unconscious first-year university student after deliberately getting her drunk at a team training camp. The court recognized that her panic, confusion, and respect for him as her instructor explained why she didn't call for help when a teammate knocked on the door.
Japan's legal standard requiring proof of "violence or threats to a degree markedly difficult to resist" places an unreasonable burden on victims, especially when 70% experience tonic immobility during assault. Though the criminal code was amended in 2017, this requirement wasn't revised. Society must shift from "if I don't say NO, I don't mean NO" to "if I don't say YES, I don't consent."
Chapter 9
Breaking the Silence: Going Public with Her Story
As a journalist, Ito considered going public with her case to prevent investigation distortion and raise awareness about quasi-rape issues. When she consulted Reuters, her employer, they declined to investigate because she was their employee, making objective reporting impossible. She reached out to Kiyoshi Shimizu, a journalist known for exposing police misconduct, who immediately offered help and introduced her to NTV journalists covering the Metropolitan Police Department.
The NTV reporters never aired her story despite initial promises. When the case was sent to prosecutors, they postponed, claiming they'd run it "at the beginning of the year" and later "if the case is dismissed." Even after dismissal, NTV never ran the story. Other journalists, including a respected Tokyo Shimbun writer, also declined to report her case, claiming timing difficulties or insufficient evidence.
While continuing freelance work, Ito visited the World Press Photo exhibition at Tokyo Photographic Art Museum. Mary F. Calvert's first-prize series documenting military sexual assault survivors captivated her. One photo showed Carri Leigh Goodwin's diary-a Marine Corps member who was assaulted, bullied for reporting it, discharged for misconduct, and later died by suicide. After her assault, Ito too had contemplated suicide, feeling like an empty husk of her former self. But these photographs reminded her she still had a voice when Carri no longer did. She realized she couldn't remain silent.
Her final option was petitioning the Committee for the Inquest of the Prosecution-a citizen panel of eleven people who review prosecutorial decisions. She filed for evidence disclosure in September 2016, and surprisingly, the prosecutor released substantial materials. She began gathering additional evidence and testimony to strengthen her petition.
Almost two years after the incident, she located and rode with the taxi driver who had transported them to the hotel. He remembered that night vividly: she had repeatedly requested to be taken to Meguro Station while Yamaguchi remained silent. Near their destination, Yamaguchi suddenly redirected to the Miyako Hotel despite her protests. The driver recalled that she fell silent, and at the hotel, Yamaguchi had to physically drag her from the taxi. The driver also noticed she had vomited in the back seat.
She was shocked to discover the MPD never questioned the taxi driver at all, despite claiming they would question everyone involved again after taking over from Takanawa Police. The driver had only been interviewed twice by Takanawa Police in May 2015. This revelation completely contradicted what First Investigation had told her about their thorough reinvestigation.
Chapter 10
The Power of Bearing Witness: Finding Her Voice
On the same day she petitioned the Committee for the Inquest of the Prosecution, Ito considered going public with a press conference. This would require immense courage-like jumping off a cliff. The timing seemed perfect with amendments to criminal law being proposed in the Diet. But anxiety overwhelmed her: Would mentioning Yamaguchi turn serious discussion into gossip? Would his right-leaning supporters attack her? Would her address be leaked, endangering her family?
When journalist Kiyoshi Shimizu informed her that weekly magazine Shukan Shincho wanted to report on her case, she agreed to cooperate if they would explain her motivation: the need for systemic change in investigations, legal processes, and assault hotlines. The article was published quickly on May 10, 2017, with reporters even investigating at the Sheraton Miyako Hotel where security immediately alerted MPD about their inquiries.
The bombshell in Shukan Shincho's reporting was an admission from then-chief of Criminal Investigation at MPD, Itaru Nakamura: "I was the one who called off Mr. Yamaguchi's arrest." The article revealed that when the Public Information Division learned about the "Yamaguchi Arrest," they alerted Nakamura and the MPD commissioner. Another revelation came when Yamaguchi accidentally replied to Shukan Shincho instead of forwarding their interview request to someone named "Kitamura"-suspected to be Shigeru Kitamura, Director of Cabinet Intelligence and part of Prime Minister Abe's inner circle.
While grateful for the revelations, Ito had hoped to emphasize the systemic problems in the legal system and investigative processes that silence victims. She refused to remain an anonymous "female victim," as this label neither defined her character nor her profession. Seeing families like those of Matsuri Takahashi (who died by suicide from overwork at Dentsu) and Rima Kasai (a middle school student who took her life due to bullying) come forward with their real names and faces inspired her.
On May 29, 2017, she held her press conference at the Tokyo District Court's judiciary reporters club, facing unexpected resistance. One journalist suggested no daughter should endure such scrutiny from reporters who couldn't run the story anyway. Despite Shukan Shincho's articles, mainstream media had barely covered her case. Even the Foreign Correspondents' Club rejected hosting her, calling her story "too personal, too sensitive."
After the press conference, her comments about Diet deliberations on an anti-conspiracy law delaying rape law revisions were misconstrued as politically motivated, triggering online harassment. Her personal information was exposed, and she received threatening messages. The stress was so severe that she collapsed immediately after the conference and remained bedridden for days, unable to eat solid food.
Going public meant accepting she might never work for Japanese companies again. She'd been repeatedly warned that filing a complaint against the politically-connected TBS Washington bureau chief would make finding journalism work difficult. Uncertain about employment prospects with limited experience and only a Japanese passport, she chose to believe in her abilities. She began pitching documentary ideas to foreign media, starting with BBC London. Eventually, Channel News Asia commissioned her documentary on elderly people dying alone as a one-hour program, and other projects followed.
Chapter 11
The Ongoing Fight for Justice and Change
Five years after her assault and three years since publishing her book in Japan, Ito spent countless hours in courtrooms and speaking about her trauma. Being on Time's list dispelled the labels of "victim" or "liar," making her feel she could go on living her life as Shiori Ito with her head held high.
In December 2019, she won her two-year civil trial for quasi-rape, with the court acknowledging "there had not been consent." If Japan's criminal law routinely prohibited sexual intercourse without consent as in many Western countries, perhaps she wouldn't have needed to write this book. Mr. Yamaguchi's 130-million-yen countersuit for damages was dismissed, with the court recognizing the book's public importance in calling for legal and societal reforms.
Ito still needs answers to two questions. First, why did Itaru Nakamura call off her arrest warrant? Despite multiple attempts to interview him, he rushed away without explanation. Second, she wants to know why key information from the Takanawa Police Department's report was omitted from MPD's investigation report. After her case was deemed "nonprosecutable," journalists shared rumors claiming security footage showed her walking normally, suggesting she was conscious throughout. These rumors raise questions about MPD's report.
The established facts remain clear: Yamaguchi and she met to discuss a work visa, they weren't romantically involved, he knew she was in a "stupor," he brought her to his hotel room, sexual intercourse occurred, DNA evidence was found, and an arrest warrant was issued then mysteriously canceled by Nakamura.
As Jodi Kantor, the New York Times journalist who helped ignite #MeToo said, "You cannot solve a problem that you can't see." We've gone from invisible, nameless victims to "Me." In her ongoing work, Ito wants to continue making things visible-because that's how they will change.
Through her courage in speaking out, Shiori Ito has opened Japan's "black box" of sexual assault, shedding light on a system designed to protect perpetrators rather than victims. Her story is not just about one woman's fight for justice, but about challenging the structures that enable and perpetuate sexual violence. By refusing to remain silent, she has given voice to countless others and sparked a movement for change in a society that has long preferred to keep such matters in the dark.
