Defendant Yuta Ishino (from the judo school’s website; now deleted) From the many incident reports covered by FRIDAY Digital in 2025, this installment of the specially curated 2025 Heinous & Major Crimes Wide focuses on the Former Judo School Head Sexual Assault Trial, in which a man who ran a judo school committed crimes against nine of his students. FRIDAY Digital reported on this case in four articles, from the first hearing on June 27, 2025, through the sentencing hearing on October 22 of the same year. This article revisits those reports with newly added details. A large amount of child pornography discovered on his smartphone The case began on November 7, 2024, when Chiba Prefectural Police arrested defendant Yuta Ishino on suspicion of assault in connection with a May 2023 incident in which, during a training camp, he forcibly poured soy sauce into the mouth of a male child, A. As police investigated the assault, they discovered a large amount of child pornography on Ishino’s smartphone, which led to the exposure of his sexual offenses. Investigators analyzed the child pornography and identified each victim one by one. Starting with his arrest on January 7, 2025, for sexually assaulting B, who was under 13 at the time of the incident, and culminating in his arrest on June 10 for violations of the Child Welfare Act involving victim I, the number of victims ultimately reached nine. Ishino was arrested and indicted on ten charges, including assault of minors, violations of the Child Welfare Act, non-consensual sexual intercourse, filming sexual acts, and violations of the Child Pornography Prohibition Act. At the first hearing on June 27, 2025, the prosecutor spent 30 minutes reading six indictments aloud, laying bare the horrifying details of Ishino’s crimes. 《“Between 2022 and 2024, the sexual assaults committed against five former female students, B through F, all of whom were under the age of 13 at the time of the incidents, were carried out while the victims were asleep, and in fact they were not even aware that they had been victimized. Notes were discovered on Ishino’s smartphone containing entries such as sleeping-pill camp — give sleeping medication when they go to bed.” “The defendant planned to engage in sexual acts with B, who was participating in the training camp, and gave her juice containing a sleep-inducing drug. He then sexually assaulted B while she was asleep.” “Inside a car parked at a service area, the defendant lifted the clothing of D while she was sleeping, touched her body, and sexually assaulted her. During the training camp, he also sexually assaulted D while she was asleep. On another day, again inside a car, he ejaculated on D’s face while she was sleeping and committed an obscene act by placing semen in her mouth.”》
