WAKAYAMA (TR) – The 30-year-old widow of Kosuke Nozaki, the wealthy businessman famously dubbed the “Don Juan of Kishu,” has abruptly suspended her social media activity after making sensational claims about her high-profile murder trial earlier this month.
Saki Sudo, who was acquitted in both her district and high court trials over the 2018 fatal methamphetamine (kakuseizai) poisoning of her husband, has drawn significant attention on X (formerly Twitter).
Despite her legal victories, the Osaka High Public Prosecutors Office has appealed the ruling to the Supreme Court, ensuring her court battle continues.
“I’m the real deal”
An account believed to belong to Sudo, launched in October 2025, had been laying bare the behind-the-scenes reality of her interrogations and her candid thoughts on the trial. The profile biography bluntly stated, “People say I’m fake, but I’m the real deal,” and featured a photo of her official court judgment document as its header.
In a post dated April 8, Sudo coldly analyzed how her polarizing persona could have influenced her fate in the courtroom.
“Just between us, I’m well aware that I’m the type of person women hate,” she wrote on April 8. “So the moment I found out in the first lay judge trial that the presiding judge and four out of six lay judges were women, I thought I was doomed.”
“So many slutty women”
Sudo’s account also shared photos of letters she received while held in the detention center and disclosed surprising anecdotes about her interactions with her defense team, sparking widespread online debate.
The posts are defiant and cocky. On April 6, she posted, “The prosecutor has appealed. Lol.”
Sudo also described her interrogation following her arrest. She claimed that she was “tied to a chair with ropes for hours, yelled at in Wakayama dialect like, ‘You killed him, didn’t you?'”
She also says the table was kicked. “This is an interrogation method unthinkable in the Reiwa Era,” she wrote.
Sudo also discussed her public perception, including a comment from her lawyer: “Saki, you’re the type of person women dislike, so I was afraid it might affect the trial.”
“I thought that was true,” she wrote on April 8. “I guess what he meant was that my lifestyle is disliked by serious people. But then, during the questioning of a witness, that lawyer called her a ‘slut like Saki.’ Lol. I thought, ‘Am I really hated?'”
Later, she added a correction: “I wrote that my lawyer called me a slut, but it wasn’t about me, it was about someone else. There are so many slutty women mentioned, so I got confused. I’m sorry.”
Halting posts
The next day, however, she announced she will halt further posts.
“My lawyer warned me out of concern, so I’m taking an indefinite break,” she wrote. “(I never thought I’d be saying something like an idol, lol.) I don’t know if my statements will influence the Supreme Court, but I’ve been told to refrain from making any rash statements until the trial is over.”
She said she only criticized the methods of the police, prosecutors and media.
“I didn’t incite the court at all,” she wrote. “In fact, I’m grateful that they made an appropriate judgment in that situation.”
Meth poisoning
Nozaki, who notoriously bragged of spending billions of yen courting thousands of women, died of acute methamphetamine poisoning at his home in Wakayama Prefecture in May 2018.
Sudo stands accused of administering the lethal dose, a claim she has denied in both trials.
While lower courts found insufficient evidence to convict Sudo of the murder, prosecutors are continuing their fight at the nation’s top court.
