Police in Kashiwa, Chiba Prefecture, plan to arrest a man in his 30s who formerly headed a disability group home on suspicion of assault resulting in death after a 19-year-old male resident with an intellectual disability died under suspicious circumstances in 2025. Investigators believe the former representative assaulted the resident, leading to his death, and are also examining possible liability among staff members who allegedly failed to report the abuse despite being aware of it. Police suspect the victim may have been subjected to routine violence and are continuing the investigation.
