What was the defendant, who was engaged in “papa-katsu” with girls the same age as his students, thinking while standing at the classroom podium── (photo is for illustrative purposes) Arrested for “papa-katsu” with three girls “Personally, I have a small request: please bring your school uniform, gym clothes, and short-sleeved shorts. I would also like to record during the act.” A junior high school teacher in Niigata Prefecture, who was looking for girls for papa-katsu via social media, reportedly sent this message to high school student A (15 at the time). “Petit” apparently means that sexual intercourse is not involved. “On October 15, 2025, the Omiya Nishi Police Station in Saitama Prefecture arrested Gaku Nakamura (36), a defendant working at a public junior high school in Niigata Prefecture, on suspicion of non-consensual sexual acts and other charges. Nakamura is suspected of having promised to give money to A in June this year and then engaging in sexual acts, recording the acts on video. In addition, he was re-arrested on November 4 for committing similar acts with junior high school student B (13 at the time) in August of last year, also on suspicion of non-consensual sexual acts” (reporter from a national newspaper’s social affairs department). The case was triggered in August 2023 when the Omiya Nishi Police Station received a report from the mother of another teenage girl living in Saitama Prefecture that my daughter is meeting strangers and receiving money. “During the investigation, Nakamura came under suspicion. When police conducted a search of his home, multiple sexual images and videos of girls were found on Nakamura’s smartphone, which led to the discovery of the case. The police analyzed the images and videos stored on Nakamura’s phone to identify the victims. On September 25, he was arrested and indicted for non-consensual sexual acts and other charges against junior high school student C in Kanagawa Prefecture. After that, he was arrested in connection with A and B.” Nakamura reportedly admitted the allegations, saying, “It’s true. I was under work-related stress” (same source). On December 22, Nakamura’s first trial was held at the Saitama District Court. In this trial, he faces four charges, including non-consensual sexual acts and filming sexual acts of A and B, violations of the Child Pornography Prohibition Law, and requesting to meet with a person under 16 years old (A).
