Prosecutors requested a 20-year prison sentence on July 10 for Kenichi Takano, 44, who fatally stabbed livestreamer Airi Sato, 22, during a live broadcast in Tokyo’s Takadanobaba district in March 2025. The attack left Sato with 55 stab wounds. Takano, a former fan of Sato’s, admitted to the killing. The verdict is scheduled for July 15.
The attack and its brutality
Sato was stabbed repeatedly in the neck and chest while broadcasting live on March 2025. Prosecutors described the assault as “extremely cruel” driven by revenge and anger. The defendant filmed Sato covered in blood after the attack, according to court documents. Takano had a prior financial dispute with Sato before the killing.
Prosecution’s case for 20 years
Prosecutors argued the stabbing was premeditated, noting the 55 wounds constituted “extreme cruelty.” They stated that even if money troubles triggered the act, Takano’s decision to attack was inexcusable. The victim endured immeasurable physical pain, fear, and despair, prosecutors said.
Defense argues for lighter sentence
Takano’s legal team contended that financial stress drove him to commit the crime. They requested a nine-year sentence, saying he was cornered by circumstances. Takano told the court: “I took Airi Sato’s life through wrong thinking and actions. I am truly sorry.”
Victim’s family seeks justice
Sato’s mother addressed the court, stating: “I hate Takano, who took my daughter’s life in such a cruel way. Our family will never forgive him.” The family’s statement was read aloud during the July 10 hearing. The Tokyo District Court will deliver its verdict on July 15.
Final Thoughts
The case highlights the risks livestreamers face and the severity Japan’s courts assign to premeditated violence. The verdict on July 15 will set the sentence between the prosecution’s 20-year demand and the defense’s nine-year proposal.
