Throughout July‑August 2026 Japanese authorities continued a broad‑spectrum crackdown on sexual exploitation, indecent conduct and related violent crimes. Following the July 18 dismissal of charges against a Kagoshima host‑club operator and a fraud suspect, prosecutors again dropped two cases on July 18, citing privacy and evidentiary concerns. In the same period, arrests were made for non‑consensual filming in Hyogo (camera‑equipped glasses) and a naked‑body incident in Sapporo, echoing earlier indecent‑conduct cases. Police seized several individuals involved in illegal sex‑industry operations, including a host‑club owner in Kagoshima (June 29) and a men’s‑esthetic salon in Chiba (June 29). Teacher misconduct was targeted with arrests of two Chiba educators for indecent assault of minors (June 24). Multiple sexual‑assault arrests occurred across the country: a 23‑year‑old in Chiba attempted under‑skirt filming (June 18), a 59‑year‑old Peruvian on a Saitama train (June 20), and a 44‑year‑old Saitama man charged with kidnapping and sexual assault of a 13‑year‑old (June 21). Kidnapping and sexual‑abuse cases involving minors were also pursued in Niigata and Tokyo. Violent homicide cases continued to be prosecuted, with lengthy sentences handed down in Hokkaido (27‑ and 30‑year terms, June 23) and appeals filed for a 30‑year sentence in the Ebetsu university murder (July 7). Additional murder investigations linked to robbery and organized crime were reported in Hiroshima, Fukui and Miharu City. The pattern shows intensified law‑enforcement action against a range of sexual, indecent and violent offenses nationwide.
