After His Arrest, He Sent Endless Resentful Emails to the Victim in Her 20s… “My Parents Abandoned Me”: The Childish Claims of a 52-Year-Old Stalker
He also harassed an acquaintance of the victim.
The second hearing for defendant Mitsuo Osaka (52 at the time of arrest), who is charged with stalking and other offenses against a woman nearly 30 years his junior, was held on October 27 at the Tokyo District Court.
During the defendant’s questioning that day, Osaka’s extreme “attention-seeking” behavior, driven by his intense delusions, was brought to light.
“In May of this year, Osaka was arrested on suspicion of violating the Anti-Stalking Act for sending emails to Ms. A, a woman in her 20s who was a colleague at the restaurant where he worked, containing romantic overtures and hints of suicide.
Although she was sentenced to a fine of 300,000 yen and issued a restraining order, she was re-arrested after sending Ms. A messages and images expressing resentment, such as, ‘You did it to me, didn’t you?’ and ‘ ‘I spent what little life I had left eating cold rice behind bars’”—and was re-arrested. At the initial hearing held in September, she admitted to the charges.” (National newspaper judicial correspondent)
For those who wish to know more details about this trial, it was reported in the October 1, ’26 issue of Friday Digital.
Defendant Osaka appeared in court with a hairstyle featuring gold highlights and dressed in a tracksuit. Compared to her first hearing—when her skin was pale and lifeless—she had regained some color, and her stride as she walked to the witness stand was steady.
In ’24, Ms. A (then 20) began working part-time at the restaurant where defendant Osaka was employed, and the two became coworkers. Since they shared a common interest in music—including the same favorite band—defendant Osaka and Ms. A began going out to meals and concerts together.
Osaka believed she was in a romantic relationship with A, but in March ’26, A began dating another man. When A told Osaka, “I’m seeing someone else, so I can’t go out to eat or to concerts with you anymore,” Osaka made suicidal remarks, prompting A to consult the police, which led to her arrest.
According to the supplementary indictment read by the prosecution (Editor’s note: an indictment newly drafted based on statements made by Defendant Osaka during the initial hearing held in September), Defendant Osaka’s anger grew not only toward Ms. A but also toward Ms. B, who had introduced Ms. A to the man who would later become her boyfriend. On her Instagram, she posted messages such as: “I’m being driven to the brink and will be killed” (Editor’s note: meaning “Defendant Osaka will be driven to the brink mentally and die as a result of Ms. B’s actions”) and similar messages.
In court, she acknowledged these posts, stating, “There is nothing in particular that is incorrect.” In a written statement read by the prosecution, Ms. B described her fear and anger as follows:
“When I learned that Defendant Osaka was loitering around the station (nearest to my home), I was overcome with anxiety. I ask that she be given a severe punishment.”
Reason for Not Eating While in Custody
When the defendant’s questioning began and the defense attorney asked about his state of mind at the time of the crime,
“I was quite confused. I had grown tired of living and wanted to die,”
He made the following statement regarding his motive for the crime:
“I wanted people to know that there are people who feel this way. I was aware that it would cause distress, but I felt abandoned and thought my life had no value.”
He also stated that, driven to despair by his unfulfilled feelings, he had disposed of his personal belongings and identification and had been wandering around the train platform intending to jump in front of a train.
He reportedly refused to eat while in custody, but when his lawyer asked why,
“I was put in custody without being interrogated, so I wanted someone to listen to my side of the story,”
she insisted. When her father, who was acting as her guarantor, failed to pick her up upon her release on bail,
“I felt my parents had abandoned me too,”
he revealed.
However, it later emerged that a miscommunication with his parents was the reason they couldn’t come to pick him up. “I want to return to my parents’ home and get my life back on track, ” he declared.
When the presiding judge asked, “Is there anything you’d like to do once you’re back in society?” she replied, “I want to start working as soon as possible.” The judge gently urged her,
“I don’t want you to give up on yourself, and I don’t want you to die. I hope you have something you want to do for that reason.”
The defendant’s questioning concluded with Osaka’s apology: “I’m sorry for dragging others into this because of my own misconceptions.” The prosecution argued, “This was a persistent and malicious act. She committed the crime just three weeks after the previous incident, so the likelihood of reoffending is high,” and sought a six-month prison sentence.
On November 5, the Tokyo District Court sentenced her to six months in prison, suspended for three years with probation. Osaka returned to her parents’ home to try to restart her life at the age of 52—
