About this episode

This episode explores the chilling unsolved mystery of 'The Monster with 21 Faces' in Japan during the mid-1980s.

In the mid‑1980s, a shadowy group calling itself “The Monster with 21 Faces” terrorized Japan by tampering with popular candy and snack brands, sending taunting letters to the police and media, and threatening to poison products on store shelves. Their campaign of blackmail, arson, and public fear forced massive product recalls, humiliated law enforcement, and dominated national headlines, yet despite intense investigation and one suspect driven to suicide, the group vanished without a trace and has never been identified, leaving behind one of Japan’s most chilling unsolved mysteries.
