The Setagaya Murders: The Unsolved Miyazawa Family Case

On December 30th, 2000, the Miyazawa family murders shocked Japan and became one of the most chilling unsolved murder cases in Japanese history. In the quiet Tokyo suburb of Setagaya, 44-year-old Mikio Miyazawa, his wife Yasuko, and their children Niina and Rei were brutally killed inside their home — a crime now known globally as The Setagaya Family Murders or simply The Miyazawa Family Murder Case. What makes this case infamous isn’t just that it remains unsolved. It’s what the killer did after. The suspect stayed inside the home for hours. He ate the family’s food, drank their tea, browsed their computer, tended to his injuries, and even slept on their couch before disappearing without a trace. Despite leaving behind DNA, fingerprints, clothing, and dozens of forensic clues, the killer has never been identified. This episode breaks down the facts, theories, and evidence behind one of Japan’s most haunting cold cases — a case that continues to baffle detectives 25 years later. If you're interested in unsolved mysteries, Japanese true crime, cold cases, international murder cases, or the Setagaya murders, this episode is one you won’t forget.
