In the snowy serenity of Sapporo, Japan, a city known for peace and low crime, no one could have imagined the horror that would unfold behind the closed doors of a love hotel. Runa Tamura, a quiet, socially reclusive woman with a traumatic past, met someone online she thought she could trust. “Tomo” was kind, funny, and finally made Runa feel seen. But Tomo wasn’t who she claimed to be, she was Hiroshi Ueno, a 62-year-old man with a history of deceit and disturbing behavior toward women.

When the truth came out, Runa’s fury ignited. What followed wasn’t a breakup, it was a calculated, cold-blooded revenge, orchestrated with the help of her own parents. Police would later find Hiroshi’s body dismembered, his head stored in an icebox, and evidence of the crime hidden beneath a web of lies, loyalty, and psychosis.

This is not just a story of catfishing gone wrong, it’s a descent into a disturbing family dynamic, twisted justice, and a mystery that still has Japan asking: was this revenge, or something even darker?
