Primary School Teacher Shocked to Discover Unusual Dead Body Part Under Public Toilet Seat at School

September 2, 2025

Decades-Old mystery: Body Found in Japanese School Toilet Remains Unexplained

A chilling discovery in a small Japanese village in 1989 continues to haunt authorities and locals alike. The remains of a man were found inside the cesspit of a school toilet, a case that remains unsolved despite extensive examination and persistent public curiosity.

The Gruesome Discovery

The unsettling find occurred at a primary school in Miyakoji when a teacher, Yumi Tanaka, noticed an anomaly while using the restroom. She observed what appeared to be a shoe protruding from the squat toilet. Upon further inspection of the connected septic tank, she was horrified to discover two bare human feet.

Retrieving the body proved incredibly difficult,requiring authorities to cut open the narrow 36-centimeter access point to the tank. What they found was a man eerily curled up, partially unclothed, with his coat neatly folded beside him.

Identifying the Victim

Forensic teams faced a significant challenge as the body was heavily soiled, necessitating a double cleaning before identification was possible. Ultimately, the man was identified as 26-year-old Naoyuki Kanno, a maintenance worker at a nuclear power plant and an active member of the local youth group.

Kanno had been missing for approximately two days before his body was located. His parents reported his absence after finding his car abandoned near a nearby farmhouse.

Conflicting Theories and Unanswered Questions

Several theories emerged in the wake of the discovery. One speculation suggested Kanno may have intentionally entered the septic tank, perhaps with the intent to eavesdrop or spy. However, this explanation was questioned, as it seemed unlikely he would risk becoming trapped in such a confined space. His family reported no prior unusual behavior.

Another line of inquiry focused on Kanno’s employment at the nuclear power plant, especially considering ongoing debates about its expansion at the time. A colleague of Kanno’s had died by suicide a month prior, raising questions about a possible connection, though no concrete evidence emerged.
